These questions & answers most troubleshooting and fixing issues with forced hot water baseboard heat were posted originally at BASEBOARD Estrus - please exist sure to also review the how-to communication given there.

Tepid or Cold Baseboards: 5 Steps to Ready a Baseboard that Does Non Become Hot

1. Make sure that your room thermostat is ready to a temperature higher than the temperature in the room - so that it is calling for heat.
   Only if you're sure your thermostat is calling for rut, continue below.

   Come across THERMOSTATS, HEATING / COOLING if you need help with that device.

2. Zone Valves: if your room thermostat controls a zone valve brand sure that the zone valve motor operates and that the zone valve opens; note that some hot water heating systems utilize one circulator feeding multiple zones controlled by individual thermostats and zone valves while other hot water heating systems may apply multiple circulator pumps, ane per heating zone.

   If you lot're sure your zone valve is open (or at that place are no zone valves), continue below.

   Othewise see ZONE VALVES, HEATING for details.

3. Check that the circulator pump(due south) are running;
   If the circulator is running the pipes earlier and after the circulator should be hot. If so, continue below.

   See CIRCULATOR PUMPS & RELAYS for details.

4. Make sure that your heating boiler is working, that is that the heating boiler turns on and off unremarkably. A hot water heating boiler may non turn on immediately when y'all plough upwards the room thermostat:

   if the water temperature in the boiler is already to a higher place the aquastat'south cut-in temperature the circulators volition send hot h2o to the radiator and the boiler volition turn on later when its temperature is dropped by returning water from the cooler radiators in the building.

   When the boiler temperature falls below the aquastat's cut-in temperature the boiler should run. If it does, keep below.

   Or see NO HEAT - BOILER

5. Check for an air-bound heating line or baseboard segment if the baseboard never gets hot.

   See AIR-BOUND HEATING SYSTEMS

   You may also need to encounter AIR BLEEDER VALVES and if you need to add bleeder valves

   Run across AIR Bleed VALVE INSTALLATION

6. Cheque for dirt or grit clogging the finned tubing of baseboard heaters that utilise that component (photo at above-left) or bank check for air flow blockage at the bottom opening (cool air inflow) and top opening (warm air outflow) at the baseboards if the actual baseboard piping gets hot but not enough oestrus comes into the room.

FP

Allow'due south start with a expect at the air haemorrhage procedures at AIR-Leap HEATING SYSTEMS https://inspectapedia.com/heat/Air_Bound_Heating_System.php

In that location are a couple of ways to force h2o through the zone using a pony pump vs adding bleeders, though ultimately you lot may want to add some air bleeder valves.

Sorry. That previous message was not anonymous. It was me! FP!

Cheers!
Forgot to mention; in that location are no bleeder valves on the zone in question, and they are baseboard heaters beneath the level of the boiler by just that much.

Actually, only one of the four zones (the largest and most circuitous) has bleeder valves and that just on one-half of the radiators.

My procedure (correct me if this is misguided) then is to shut off the send and render valves of the other three zones (all thermostats off and burner off) at the banality, leaving only the zone I am haemorrhage open. I then open the drain valve of that zone (into hose) and up the incoming water force per unit area at the regulator valve. This is all of course at the banality. I allow that run for a while keeping an eye on the hose end for signs of air.

When satisfied, I cut the water pressure back down and immediately close the drain valve, adjusting pressure if needed so open all back up, turn on burner, and call for heat.
Should I not be endmost off the other zones? Likewise, should I have the zone'south impeller ON when bleeding?

FP

Showtime let'south wait to make certain there isn't a balancing valve or service valve that'southward closed.

2nd, even though you've tried to drain the air out of the zone, information technology may still be are bound.

Information technology can exist difficult to button air up and then down then around and then out to a bleeder depending on where your bleeders are located.

Offset at AIR-Spring HEATING SYSTEMS

Where we refer to using a
a pony pump to force air out of an air bound hydronic heating system - I might attempt that side by side.

I have a hydronic organisation with iv zones. One zone in the basement, the shortest run and closest to the boiler, is a baseboard zone with ii baseboards.

These stopped making estrus and I diagnosed and found the Taco circulating pump to be dead. I replaced that, confirmed that it was working, and bled the entire arrangement.

I bled the zone in question for quite a while. It is a short zone run with virtually all of its ~30' total send and return run of copper exposed and visible.

With system up and running again and the new motor definitely working, the zone is still non heating upwards. On the zone in question, the inlet to the new pump and the pump torso get hot when thermostat is on. The drain valve just above on the riser coming out of pump lets out hot water when opened.

HOWEVER, just beyond this valve and on the continued run the pipes remain common cold. How is this possible? With the zone then exposed I can run into no leaks nor imagine how air could be again "settling" in this the lowest run of the business firm. What could be going on here??

nosotros demand an experienced heating service tech onsite;
she will
- bank check boiler temp
- check circluators and/or zone valves
- check air bleeders

No, this just started one week ago. Before the rooms were nice and warm, now they are absurd.

Upwardly

And so have the cool rooms e'er been too cool on cold days? That'd be diagnostic and would suggest

- inadequate amount of heat existence provided in feet of baseboard or number of radiators
or
heating pipes to those rooms run through a common cold space similar an unheated attic or crawl surface area
or
recurrent air bound pipes
or
- an unusual rate of heat loss

I'd argue for a recurrent air blockage trouble commencement IF on bleeding air the pipes all of a sudden rut upwardly;

the problem is even after all that the rooms are still cool.

Sounds right; air in the hot h2o pipes can cake hot water menstruation; all the same if at that place's a leak elsehwere or the whole system needs haemorrhage the problem will return

I believe it is forced hot water. When the landlord came he took the air out to the betoken information technology was water that came out. According to him there is no problem.

Upward

The thermostat will only respond to the temperature correct at its very location. And then information technology'southward easy for other apartment areas to be at a different temperature than the room where the thermostat is mounted.

But if thermostat is fix to 25 and the temperature at the thermostat never reaches that number and then the commitment of estrus to the room is inadequate; that could exist any of a number of problems that depend on the kind of heat such equally steam, forced hot water, or air.

In my apartment the heat u.s. gear up at 25, but the thermostat shows 20. My living room is nice but the bedrooms are cool. Can you lot please tell me the trouble. I would very much capeesh any help you lot could provide.

Thanks I really capeesh the advice. I'll take a expect at adding an auto bleeder and relocating my bleeder every bit well. Hopefully it's only air and I'll become it out.

Stephen

When I've had poor heating issues like this it's often been considering I thought all the air was out of the piping when it wasn't, so that's my commencement focus.

For instance, y'all might bleed a bolus of air near a bleeder valve but the next rut-on bicycle may push some air from downstream in the system to the aforementioned bespeak.

That'south a reason to be sure to bleed the entire system and to install float type air vents at high points at the boiler and at the highest other points in the building.

Other possibilities could be a solder blob blockage if in soldering a joint you lot pushed as well much solder into the connection.

And aye at that place tin can be a flow problem at tees in copper baseboard pipe. For case at a left and right tee feeding ii sub-zone loops, if one of those loops, say the left one, is longer or higher than the other, say the right i, then the lower-resistance loop will get more hot water.

Plumbers may install a balancing valve on loops to set the trouble. The balancing valve tin exist anywhere in each loop that's user-friendly.

Thanks for the information. So if I was to assume I got all the air out, is there annihilation else I should exist looking for?

I don't understand why the rads start to get warm and then pitter out. In that location is some other rad for upstairs that is farther downwards the same return line that I spliced into and that one is fine.

To me it almost seems similar the water on the supply side is not able to push through the rad and become through the render line. Information technology starts to because the radiator starts to warm but then stops quite suddenly. It'due south infuriating lol. I used orange pex with an o2 barrier to supply and return the water.

Does that negatively touch on something? I also cutting into ane/2 inch supply and render line is that not a big enough piping?

further back on the supply and return it's a larger pipe that's either three/4 or an inch in diameter. Should I splice into there?

I also had taken the two return lines from the two radiators and teed them together and then ran one line support to the main render is that my trouble maybe do I need to separate render lines? Any help is much appreciated.

Stephen in my OPINION where you have that bleeder is ok - information technology won't hurt a matter, just information technology'd exist more effective on a loftier bespeak in the pipe. Detect how the return branches towards the wall horizontally (at your bleeder elbow) and then runs Upwards?

Any air in the system wants to be in that upwards-line so if that line has a turn somewhere, a bleeder elbow there will exist helpful.

Air in heating lines is actually sneaky. You can get a "partial" blockage of air in the horizontal lines in which some water gets by but an air bubble is obstructing much of the flow.

You'll know when you've got the air out because assuming the boiler is hot and the circulator is running, when the meddlesome air blob is removed the baseboard lines will get quite hot in but a few minutes.

See AIR-Spring HEATING SYSTEMS https://inspectapedia.com/rut/Air_Bound_Heating_System.php

And see AIR BLEED VALVE INSTALLATION https://inspectapedia.com/heat/Air_Bleed_Valve_Installation.php

You'll notice that I attempt to position my bleeder valves on elbows such that the valve is upright and catches air rising.

More air bleeders are good at every loftier signal in the pipe, and of course you lot tin can add float type automated air bleeders equally well as manual ones.

I installed them coming off the return line. I attached a photo.

I would bank check first for a partial air blockage; where have you installed air bleeders?

Hi. I accept installed ii new 8 ft baseboard hydronic radiators in my basement that I'yard refinishing

. I simply came off the supply and return lines that are located in my basement already. The new rads first to get warm and their corresponding supply lines get pretty hot, but then they cool rapidly and the rads never go hot.

The residuum of the firm is fine notwithstanding.

Is information technology too difficult for the render flow to push 8ft vertically? And is that why the rads don't become hot? There is no air in the line that I can find. Practise i need a bigger circulator pump? Thank you for the aid!!!

Although I have not come up across their apply in adding heating baseboards, there are plumbing techniques that allow a plumber to cut into a water filled line when the water cannot be shut off.

There's also a pipe freezing technique or yous can install a quick-and-easy Shark-Bite shutoff valve.

In our plumbing articles I have besides described a really neat invention that a Mexican plumber showed me he had built that inserts into an active h2o line and uses an expanding plug to temporarily cake the line, only I don't think that's going to be suitable for your awarding.

Of course the freezing technique would expect that the heat is off in the organisation is cool.

Alternatives that will work for y'all are all summarized

at EMERGENCY WATER SHUTOFF VALVE

In any example you're still going to need to bleed air from the system when the additional anxiety of baseboard have been continued.

With and so niggling information I can just brand a vague guess. Merely it'southward possible that your radiator Outlet is blocked or chock-full with debris such as rust flakes. If hot h2o is definitely entering the radiator but the rest of the radiator body stays cold the radiator is either Airbound or Outlet is clock. Since you lot've led the top of the radiator where are would escape and you lot're getting no more air That's What suggests information technology may be clogged or blocked. Information technology'southward time to get some assist from a heating service technician.

The hot water radiator stopped heating all of a sudden. I bled it, some air came out but not much. I bled it 3 times, I permit water out but radiator is nonetheless common cold. The water that comes out is very hot but the radiator is very common cold. What can I do?

Clive, it's standard copper plumbing (except thinner copper) - cut and solder. If you are trying to reduce oestrus output there are better alternatives

First: close the baseboard top louver

More trouble: remove some of the fins from the tubing to reduce its radiation

I have a baseboard water heating organization installed in the 1960s when my bungalow was built ...but like the photo (ours in grey exterior though). How do we shorten the catamenia and return pipes?

The wall surface area above our 3 yr old electric baseboard heater is very hot to the bear on. The thermostat is a wall mounted style and is likely 25+ years old.
This seems like an air circulation problem to me?

The unit of measurement is installed resting on the floor, however the intake area is at least i/2 inch off the floor.
Thank you

Denice,

Since baseboard in a unmarried zone is normally run as one cereal Loop of piping information technology's non possible to turn one of the baseboards off considering that would turn off everything in the loop.

However what you tin do is to Reduce the air menses through the baseboard in the room that's too hot. That can be washed past endmost movers at the outlet or top of the baseboard if there are whatever. Foremost cast iron baseboards that do not accept louvers you can block the air entry at the bottom for example with carpeting. Or you could experiment just was some towels.

Likewise if the other baseboards are never getting hot it maybe that your system is partly air jump - that's a status that your heating service tech tin can correct.

I take old bandage fe baseboard heaters in my business firm. Zone i takes care of the start floor and upstairs bathroom, everything skilful there. My trouble is zone ii takes care of the 3 bedrooms but 1 bedroom gets extremely hit while other two are comfortable or cooler.

I'd similar to know how to decline or even completely cut the heat off to the very hot room. I checked at both ends in each room and in that location are no shut off knobs, merely bleeders. What can I exercise ?

Check for the louvered meridian opening is in the open position

Baseboard is hot on pinnacle but tin can't feel the heat coming out of it.

New boiler no heat to second floor

Lex,

As the whole house is on one heating zone you lot may simply desire to reduce the heat output of the upstairs baseboards past closing their output louvers.

Opening the windows non only increases your heating bills, it actually speeds the move of warm air from downstairs to the upper floor.

We accept an onetime (1900's) ii story house with hydronic hot water baseboard heating. The thermostat is on the first floor and when it is set at threescore or so the showtime floor rooms are nigh threescore. However, the rooms on the second floor are 10-15 degrees warmer.

Is there some mode to fifty-fifty out the heat? Right now we open a window on the second floor but that seems to exist not platonic.

On 2022-05-20 John: how much does dust cake baseboard estrus output

Interesting I tin't notice any published data on how much dust and clay reduces the efficiency of radiant fin tube. Muddy coils take a pregnant result on forced air systems.

I would await the the negative result would not be as much, merely who knows for certain. Does anyone know the approximate percent reduction in efficiency form dirty and dusty fin tube?

Reply:

I have not seen quantitative analysis, just have a look in the photograph shown hither. When the baseboard is dust clogged like shown y'all're probably blocking at least l% of the air menses through the heater.

What if We've got Hot H2o Heating Radiators, Not Baseboards

The five diagnostic steps above still use for hot water radiators, but yous've got an additional advantage: there may be a radiator command valve (carmine circle in our photo) to check (is the radiator turned on?), and in that location may be a handy air bleeder valve nigh the top of the radiator (blueish circumvolve in our photo).

If your estrus is not from a heating baseboard (like the unit shown at the top of this page) simply instead is coming from a hot water radiator (shown at left) or steam radiator then yous need to see ane of the two articles given immediately below:

Cheque if the circulator is a divide pump for this zone and so you don't have a zone valve.

There may be a flow-command valve that is stuck open or manually opened, letting hot water circulate by convection or when other pumps are running.

(Mar xiv, 2022) Mark said:
Hope someone tin answer Joe and Doreen's questions (and mine). Hither's mine: My mom thinks if you lot open the movable cover on her baseboard hot water radiators she'll get more than heat.

I figure they were made such that when you continue the cover every bit it should exist (practically closed, about one/4 to 1/2 inch open from the side piece), this allows heat to build, and so more rut is generated. Any confirmation/thoughts on this? Thanks!

Reply:

Doreen and Marker:

there's zero combustible on the baseboards themselves: copper, aluminum, steel components make up the unit. Check for a spill or for something that has fallen into the baseboard unit.

Unless the smelly baseboards are actually leaking, the smell is most likely from something that is being heated such as a spill on the baseboards or nearby, or paint or wall paneling or fifty-fifty something Iin the wall or floor cavity about the baseboards. Search InspectAPedia for. SMELL PATCH Examination to see a low price method that might help pinpoint the source.

Mark:

Opening the hinged louver along the top of a heating baseboard increases the estrus output by permitting more air to circulate through the unit, entering at the bottom, exiting at the height, moved by convection.

Closing the louvers along the height outlet of a heating baseboard will reduce the heat output equally it slows convective air movement across the finned tubing of the baseboard.

Your mom is correct.

The rut is generated at the boiler, not in the baseboards.

You lot are correct that if you airtight the louver the baseboard piping would feel hotter. Only that'due south considering you are no longer cooling information technology by moving room air across information technology. Information technology's libation considering information technology'due south not sending oestrus into the room.

Question: banging from the heating pipes

(Mar 15, 2022) Jeff D. said:
I accept baseboard, hot h2o, furnace heating and shortly after my heating system turns itself off I hear a loud banging noise that comes from the last convector in the loop. I'k guessing that its spring up air but I frequently bleed the air from this concluding convector nevertheless I still hear this banging noise. What else can it be?

Reply:

You lot should not have to be frequently bleeding air pit of a baseboard. Either at that place is air left in the system that finds its way to the baseboard or there is a leak to find and set.

A loud bang may be water hammer acquired when a circulator of zone valve closes. InspectAPedia has articles on BANGING PIPES and also on WATER HAMMER that offering solutions. Try the search function above.

Enquire your heating company for some diagnostic help, banging pipes tin ultimately be dangerous every bit it can cause relief valve leaks.

Each time the repairs are made the there are more leaks each time the boiler is fired upward. What can we do to solve the problem?

Reply:

Jerry
Nosotros demand to starting time by finding out what is causing the leaks - an accurate diagnosis: if the problem is due to freezing pipes so 1 they're repaired you may desire to use an antifreeze in the heating system. If the leaks are due to corroded pipage then all of that will need replacement. If the leaks are due to poor workmanship the solution to that is apparent in the saying.

Keep in mind that heating baseboard copper pipes are sparse-wall; if your heating organization water is corrosive that could be the problem.

So I have a hot water fed cast fe baseboard heating system. One of the baseboard units knocks at dark when the heat comes on. I bled it and every unit in the house but found no air in them, directly stream of water from each one. Any other thoughts?

Answer:

Sure, Andrew, simply search inspectApedia website (see the search box just above)

for BANGING HEATING PIPES RADIATORS

to see some useful diagnostics for both hot h2o and steam systems. I suspect a noisy valve or a trouble that's keeping yous from successfully getting all of the air out of the rad.

To Sharon, wrap parts of the fins in aluminum foil. DON'T DAMAGE THE FINS. Practise it bit by flake until you get the desired event. The foil stops the apportionment of air through the fins.

Moderator replies:

Christopher & Sharon:

Christopher'due south thought is bonny only unless your heating baseboards have a removable forepart panel yous won't have admission to wrap the fins to reduce air movement through them and thus cut the heat output.

On a standard heating baseboard the convection current (warm air rises) that occurs up through the baseboard draws cool air from the floor up through the finned copper tubing where it is warmed earlier exiting at the top opening of the baseboard.

To reduce baseboard rut output in a room or area inside a heating zone, a standard step that is effective to only close the hinged top cover forth the basboard. Past interrupting the air movement you significantly reduce estrus output. Blocking air air entry at the bottom opening of the baseboard ( such equally past carpeting ) has the same issue.

I had New hardwood floors installed. The cast atomic number 26 baseboard was already in place. The cutting the hardwood to fit under the legs and the baseboard is most flush with the floors. No gap in between. Is this ok? Will the heat of the baseboard damage that section of the wood due to constant high temperatures?

Respond:

If y'all close off the space between the bottom of the heating baseboard and the top of the floor you volition reduce the oestrus output from the baseboard as you lot interrupt convection air currents that are a bones role of baseboard design and operation. The result may be a room that'due south as well cool, longer time to heat the room, or higher heating bills.

Question: circulator not responding to call for heat

(January 4, 2022) Christopher said:
I have a two zone baseboard oil called-for arrangement. Burner starts and runs fine. The basement zone works fine. Upstairs i have replaced the thermostat and circulating pump. Information technology seems like the pump is not getting the call for estrus. Is there something between the thermostat and circulating pump i can check?

Respond:

Please see CIRCULATOR PUMPS & RELAYS - domicile

Christopher: if your upstairs heating zone is not working cheque

1. that the thermostat is gear up above room temp and thus is calling for oestrus
2. that the circulator pump runs for that zone, or if zone valves are used, that the zone valve opens

If both 1 & 2 are working properly and so the system is probably airbound - search InspectApedia for AIRBOUND HEATING SYSTEM to see how to diagnose and repair that problem.

Informative site - thank you!

I alive in a condo with a hot water heating baseboards. Estrus in the summertime months is always a big problem in the unit, getting roasting hot, and I find that the heating baseboards are quite warm to the impact (although not scaldingly and then - similar traditional radiators can be).

The heat is on the eye section of the baseboad unit that has the radiator apparatus (metal sheets), and the baseboard is non hot where the copper piping is on either side of that.

This situation exists despite the fact that the thermometor is prepare to its lowest, and the baseboards are admittedly not pushing air out when the thermometer is set at its coldest.

Is this normal? Is there a way for me to absurd down the baseboards further, so that they're cool to the touch, at least in summer ?

Respond: what to look at if the heating baseboards stay hot when you are not calling for rut

Betimes,

If you are sure that the circulator pump itself is not running, then the nigh likely explanation of the problem you describe is that a flow command valve or bank check valve above or near your banality has been manually left in the open position or has been stuck open up. The results of this condition is that hot water will circulate out of the boiler by convection fifty-fifty if the circulator pump itself is non running.

If the thermostat is set below room temperature, the heating system should finish sending heat - yous may need to wait for the baseboard to absurd downwardly; if after 30 minutes it's still hot then heat is yet circulating: in that location is then probably a problem with the zone control, thermostat wiring, or a bank check valve in the system.

See Check VALVES, HEATING Organization

New M. Please search InspectApedia.com for HEAT WON'T Plough OFF to see some specific diagnostic suggestions.

To check for a bad thermostat, just disconnect the thermostat wires at the banality cease of the thermostat excursion. That'd be at a main aquastat control or at a circulator relay. You'll recognize the thermostat wires. Follow them. Disconnecting them at the boiler stop will eliminate possibilities of a bad thermostat or shorted thermostat wires. If the heat keeps running the problem is at the banality controls.

Rut can as well broadcast when the circulator is off if the Catamenia CONTROL VALVE (Search InspectApedia for CHECK VALVES, HEATING Arrangement) is stuck open but that will usually requite a much slower menstruation charge per unit that wouldn't be likely to sound like water rushing.

Robert:

If your thermostat is not calling for estrus but the baseboards are hot, and so either there is a control snafu or

- in that location is a valve or command at the boiler that'due south manually open or stuck in open; it could be a zone valve or a check valve at the boiler that is allowing hot water to circulate past natural convection fifty-fifty when the circulator pump itself is OFF. Your condo association is wasting heating fuel if this is the case. No it's not normal. But cooling down the baseboards at your terminate is not a good arroyo every bit the underlying problems of free energy cost and waste continue.

Enquire your condo association to get help from an experienced heating service tech to notice which command or valve is open that should exist closed.

Question: install shutoffs in NYC apartment on heating system baseboards?

(Jan 22, 2022) Ray said:
I am on the board of a half dozen-story co-op in NYC. The Board requires anyone doing renovations involving their plumbing system to install shut-offs at all entry points to the flat in society to permit servicing without impacting other share-owners.

Some Board members want to extend this to include transmission shut-offs on entry and exit points for the hot-water baseboard radiator system. Is this a mutual practice? Are there whatsoever potential operational or maintenance problems?

Reply:

I do not think that's a common practise. As well, depending on how the heating piping and zones are installed shutting off a units heat could close off that of others as well. Opinion,
I wouldn't carp.

Question: baseboard vents close on their own

(January 29, 2022) Gerry said:
Some of our baseboard vents keep closing on their own. Are there clips I can use to keep them open?

Answer:

Gerry,

If yous refer to the louvered vent along the summit of a baseboard, try bending the hinge opening at the end of the vent to tighten it on its rotating pin

If you are referring to air purging vents on the heating pipage,

In that location are ii types of vents; automatic ones that include a float and vent if air is present, and manual ones that are manually opened to bleed air. The latter are usually left screwed shut. The old open and close automatically. The screw cap on the automatic vent should be left loose. If the screw cap is clogging with debris the vent may demand replacement.

Question: heat in our New England farmhouse is inadequate

(Feb 14, 2022) Alex said:
Hi - We just bought an old farmhouse in New England. We have hot water baseboard heat and woodstove. I've been keeping the thermostat at 70 degrees and yet the tiny old rooms don't get college than 55 degrees unless I'k cranking the woodstove.

I'g not even certain how to tackle this problem - information technology could be my furnace (though that seemed to exist in practiced shape when inspected twice in the last vi months - looks like information technology hadn't been cleaned in many years, but nosotros had information technology serviced and were told it's in skilful shape),

information technology could be my thermostat (it's one of those really old round dial ones), maybe the baseboard to room ratio is not enough, or possibly our pipes are clogged (our water is acidic and the copper pipes are slowly corroding - we have plans to install a water neutralizer). How practice I start to tackle this problem? I don't fifty-fifty know which kind of professional to call.

Alex

Accept a look at your thermostat. If the room temperature is below the thermostat's set up temperature so the oestrus should exist running.

If the heat is running take a look at your baseboards. Feel for heat coming from them. If baseboards are cold or tepid and so hot water is not circulating and repair is needed: mayhap to a circulator, control, or to remove air from the organisation piping.

If the baseboards are hot but the heating system cannot get the room temperature up to the thermostat set point, then your home is losing estrus faster than your heating system can provide it.

In that instance you lot need to improve the home's energy efficiency past finding and stopping drafts and perhaps calculation insulation.

In whatsoever case it makes sense to accept your heating boiler cleaned and tuned every bit that will reduce your heating cost.I'm guessing from your location that your heating fuel is oil. NO oil fired heating banality will run properly nor efficiently if information technology does not receive an annual cleaning and tuneup. I've seen equally much every bit a 25% reduction in heating toll from a cleanout alone.

Question: electrical baseboard heat in our townhouse has a mind of its own

(Feb 16, 2022) kathryn said:
Nosotros just moved into a townhouse with electrical baseboard heaters and one in our bathroom was replaced by an electrician (the heaters are 50+ years old) the one in my sleeping room comes on when turned off it has a heed of its ain.

They replaced the thermostat merely it has continued to do this the electrician said something to the contracter about a valve malfunction or something he completely confused the contractor. What else could exist causing this so I tin can be prepared when he comes in so I don't accept to have him dorsum a third fourth dimension if any he does this time doesn't work

Answer:

Kathryn the state of affairs y'all described is unsafe, risking fire or shock. Electric baseboard estrus does not use "valves" so I have no thought what that's almost.

Electrical oestrus is very uncomplicated: typically a resistance-type electrical baseboard, running on 240V is powered through a line-voltage thermostat that basically acts as an on-off switch in response to the thermostat setting and room temperature.

I'd expect the electrician to ostend that the heater itself is undamaged and to track down a bad wire, connection, or thermostat.

Question: soot coming out of oil baseboard heaters

(Apr three, 2022) Jerry said:

Soot coming from my oil baseboard heaters. How exercise I remedy this trouble

Respond:

Jerry,

Your hot h2o heating baseboards contain water; they won't emit soot. Merely dust, including sooty grit, can accumulate on the fins and tubing inside the baseboard. *Careful* vacuuming with the baseboard covers off, using a soft brush, can clean the fins and tubing, but you might want to look farther for a soot source in your abode.

Commencement past checking that your oil burner is working properly - inquire for service if it'south smoky, rumbling, noisy, evil-smelling, or if you have gone more than a year without service.
