Baseboard electric heater installed properly, yet won't work.
I have added a subpanel off the main service panel to add more capacity to my house. I have a 50Amp breaker and 8 guage wire going to the sub-panel, which is a Siemens. I have installed a 20 Amp 2pole breaker in the sub-panel and have run 12/2 heater red-sheathed wire to the wall thermostat, which is a Dimplex 2 pole thermostat. I have wired everything in accordance with the wiring diagrams. The Black and Red wires from the sub-panel are connected to the two red "Line" wires on the thermostat. Then I have run the 12/2 wire from the "Load" lines on the thermostat to the basedboard heater wires. The ground wire is connected properly. I have tested all the wires with my neon tester and each power wire at every location shows that it is carrying 120 volts (240 total for both wires). However the heater will not go on. I have used a continuity tester to ensure the heater is working. I have even changed heaters and thermostats to rule out defective heaters and thermostats. I have even bypassed the thermostat and hooked up the 12/2 wiring directly to the baseboard heater and still no heat. I have moved the 20 Amp breaker on the sub-panel. Nothing seems to work. Any suggestions would be most appreciated.

Re: Baseboard electric heater installed properly, yet...
DID YOU CONNECT TO TH SAME END YOU TOOK OUT WHEN PAINTING WE ARE DOWN TO THE CONNECTION @ THE HEATER MAKE SURE THE OTHER END OF TH ELEMENT IS CLOSED WITH WIRE NUTS AND TIGHT , LIKE I SAID WE ARE DOWN TO THE HEATER CONNECTIONS SO LOOK THERE

It is my understanding, that an electric baseboard type thermostat will work fine.The hook up should be fairly easy as they are both 110 volts. But, I need to caution you, that these heaters have a plastic housing and have a tendency to melt, if not installed properly.
You want to add a brand new sunroom onto your existing house. The problem is that you are not sure how to heat it. Electric heating with baseboard heaters will spoil the look that you want from your new room. Hot water baseboard is going to present all types of problems getting hooked in to the existing system and piping it. And, if you have hot air heating system then you will have the problem of getting ductwork to the room. There is another way to heat this room easily and efficiently.
Radiant heating has been one of the most comfortable and efficient ways for heating for many years. The problem has been in the past to find a good heating source for small radiant floors that will be affordable, effective and efficient.
This problem has been solved now, with the availability of small new electric combination heater- circulator units. These units use small electric heating elements together with a small circulator pump to give you a all in one heating source and circulator pump.
Now you just have to lay your tubing in the floor of the room you are adding on to your house. Then you run that tubing into your existing basement or other room in your house. The tubing and the electric are attached to the heating unit.Then, wire a thermostat to the unit, and you are now ready to make heat. This really makes heating a new addition room very inexpensive and easy to do.
The greatest thing about using this type of heating system is that most average do-it-yourself types can do this. All that is needed is a basic knowledge of plumbing and electric.
If you are thinking of building that little add-on and are worried about how you will heat it, think about using radiant floor heat and a small electric heater-circulator to do your project.
the baseboard heaters out put goes down a lot more than you would think when used on 120 volts ... thats because not only is the voltage half of what it should be, the current is also half .. so the total power (the product of voltage and current) is one fourth of what it would be if operated on 240 volts .. you are operating at only 186 watts instead of the 750 watts you should have .. so you would have to have 4 times as many heaters for the same heat output .. you likely have the 240 volts available (most houses do) .. there are two phases .. each 120 volts .. when both phases are used together then you get the 240 volts total .. another option is you can use heaters designed for 120 volts .. the current would increase to a little more than 6 amps per heater .. some heaters have a jumper you can move for 120 volt service or 240 volt service... you can use those with either voltage ..
from the mod number it looks like you have electric baseboard. these do not have blowers in them they work off natural air movement. but heat up rather quickly. your gonna have to chk if baseboard is getting power to determine weather or not the t stat or the heater is not working. but first chk your circuit breakers. most heaters are 220v (double breaker)
When you install the baseboard heater make sure the bottom part which is the all thing must sit over the floor and touch the tiles or carpet and use 2 or 3 wood screw against the wall. That is it and do not put any kind of paper or cotton or material things above the cover. Beside that you are ok and it is not like an electric wall heater.
Is your fuse box and main power source large enough to handle the full load if all are turned on at the same time? Are you uses two pole breakers? you might only be feeding with 110 volt. This would prevent them from getting very hot.
When your heater shuts off it trips your main breaker and that is usually associated with the interupt capacity of the breaker ( which means that while your heater is drawing current, if the thermostat says stop.. you are interupting that current demand abruptly and your getting a surge back to your breaker, You may be able to add a surge arrestor to that power feed to suppress that problem. You may also be able to repsecify your main breaker with one that has a higher interupt capacity.. Check with a local electrical supply house..explain the problem and they should be able to provide a hardware solution. Make sure you provide details on your circuit breaker brand so they can provide the proper solution.. GoodLuck
I am an electrician. You must measure the voltage across the black and red wires. Measuring each wire to the neutral will not cut it. If both your red and black wire are on the same phase the heater will not work.
To double check your wiring, measure the voltage across the two screws feeding your subpanel, they should be 240v or 208v depending on your power company. Then do the same at the breaker feeding your thermostat. Again it should read 240v.
If you have no potential across the screws it is possible that you installed an incorrect breaker. Not all breakers with two screws on them are 240v breakers. There is what is called a twin or split breaker that has two screws that are on the same phase. These are for wiring two 110v circuits, when you run out of spaces in the panel.
Double check everything. This is a relatively easy circuit to wire, even for homeowners. If the heater does not work them something is wrong so do not leave the circuit energized.
