Baseboard heater wiring questions

I have to install 2 new electric baseboards heater to replace the old one but after installing them it seem they don't produce not much heat which im asking if it's be because they are not getting 240V each.

Here is the wiring diagram so maybe i didn't connect the 2 wire correctly at the baseboard or it's the wiring ?

if wired like the drawing and connected to 240V they should work. One caveat is, a lot of the stats I've seen from Honeywell formerly Aube (CA company) have a proportional output. If the set temperature is close to the room temp they won't put out full heat.

You might post of picture of what you have so others cans see and help.

If you don't have a VOM, go get one. Without a real voltage reading, everything is conjecture.

Set the T-Stat above room temperature and measure the voltage at the heater. Report back.

the voltage reading will be interesting since that doesn't look like a line t-stat.

I'm thinkin' the same thing.

Re: Baseboard heater wiring questions

+1...looks like a furnace (low-voltage) t-stat.

I measured at both and it's at 238V.

Can you post the make and model # of the heaters and of the thermostat?

Also, are there any thermostats on the baseboard heaters themselves?

The model of the baseboards heater are LC4015W31 and the thermostat is RTH2310B.

There is no thermostats on the baseboard.

thank you

Can you post the maker names to go with those Model Numbers?

Is this the heater?
Dimplex Linear Convector LC series:

Is there any chance that the 2 heaters you have were inadvertently installed in series?

Do you have NO heat, or just very little heat?
Do you have a clamp-on ammeter you can use to measure current flow?

Dsa, the thermostat you are using won't work on baseboards. The end

Yes it's that brand , no they are not there is 2 wire going to each baseboards , i only have a voltage tester model equus 4320a.

thanks

Do your baseboard heaters have the low-voltage relay installed ?

It would be an optional part with Dimplex part numbers BLLVCxx or BLLVD.

This relay makes your DImplex baseboard heaters compatible with the Honeywell Thermostat but in that case your wiring would be different (and you still need a 24V power source, perhaps from an air conditioning system). The 240V line voltage should under no circumstances go to this particular thermostat!

Hopefully the instructions that come with the relay are better then those for the baseboard heaters (which could be much clearer).

Edit: ideally you should use a line voltage thermostat for your baseboard heaters. Are you using this thermostat just for the heaters or also to control a central air conditioning system ? If the thermostat is used to control both heating and cooling then using the low voltage relays from Dimplex is the way to go.

Was the t-stat there and working before; or did you change it at the same time you changed the single baseboard unit out for the new ones?

Before it used to be an old thermostats like this one

»www.homedepot.ca/product/honeywe···g/903031

and the baseboard where 240V and there was no issues , then i changed for a thermostat like this RTH2310B 2 years ago and it was working well.

I then decided 2 months ago to replace them by dimplex 2 with the same wattage 1000w but 2 weeks ago they started to have this issue.

So now i though it was the baseboard so i went to change them and at the same time take 1500w which would cover the 300 square feet that i have , the issues still persist so i was wondering why suddenly what would be the problem.

Thanks

There's a relay somewhere.

Hopefully!

Keep in mind that all dsa said is that it was like the one he linked to (the link points to a low-voltage thermostat). Honeywell also makes line-voltage thermostats and in some cases they do look similar on the outside.

At this point a picture of the wiring at the thermostat (and ideally also at the baseboard heaters) would be really helpful because there is just too much left to guessing.

There may be a relay/contactor somewhere that was sized according to the load of the original baseboard heaters and whose contacts are now overloaded.

It only control only the baseboard no ac on that.

As said before i had to use something similar due to the previous thermostat being a low voltage , i just wanted to be able to have different temperature at different time so that's why i changed the old one.

thanks

I'm 99.99% sure that the round one never was a line stat. In fact I was using the round one for years on my electric heat with a relay. It used to be a mercury switch on a bi-metal spiral. Replaced last year.

My house is a T-stat museum. I have 6 different kinds. in 8 rooms.

Here are the pictures , the thermostat was connected the same way the old was.

I think also there is a relay since how would that wire would connect to the 240 V
