Question about Fahrenheat Electric Convector Baseboard Heater, 3'

3 Answers

NO HEAT I am installing a noma 1000 watt heater. Controller is a line Noma line voltage double pole thermostat, wiring 12\2, breaker double 20\20. I am not getting heat. The red\black are from the breaker to line at each thermoatate terminal, load is again black\red from each terminal. At the heater I am getting 120 volts at each wire red and black. The black is connected to the black of the heater and the red to the white at the heater by wire nuts and the copper to ground. With the thermostat on I am getting no heat... I thought it might be a defective heater and exchanged it... the same problem. Any ideas? Thanks Wayne

    I am writing about a baseboard heater and got an answer about a hot water heater that does not address the problem.

  • dogmanwayne Dec 09, 2008

    When it did not work the first time, I put in a single pole thermostat also not luck. I have tried your suggestion I have 120 volts on each phase, I attached both the black and white respectively to the red and black from the breaker. No heat. I tried something different, I took one phase of the inline and attached it to the black from the heater, I than took the white to case ground and the heater started to get warm but that is only working from 120v and this is a 240 heater and should not need a neutral ground. I took a long lead and took it to ground at a j box and to the hot wire and I got a reading so It should not be a ground problem. Any ideas, Wayne

    I know it is a strange one because I mounted a 2000 watt heater of the same brand with a single pole thermostat in my other house and it works fine. The heater in question is hot but not to what it should be and like I said it took a ground from the element to get it going. I may call Noma at their trouble line for thermostats and see what kind of a response I get. They don't seem to have one for the heater. Wayne

This is a strange one!!!!!! you say you have had the heater replaced and still get the same problem?
It sounds very much to me the the model you have purchased may have a generic fault across the whole model range, unless you have an emergian switch elsewhere in the home which is not switched on

    Everything seems to be checking out fine, you have made all the correct connections via the wires and diagrams, the unit itself has got to be faulty
    Change it for a new one

    This is typical of the manufacturers not to have any support for any problems that you may encounter, this is usually because they have bought the component from somewhere else (usually china) and cannot provide support for it, meaning you are stuck at the problem at hand!!!!
    get your money back and relpace the unit with a brand which will be able to offer you decent support

    regards

HI
When an electric water heater fails to heat water, either the power to the water heater has been interrupted or there is a problem with the controls or the heating elements. 1) Be sure electricity is being delivered to the appliance. Check the main switch on the water heater and the circuit breaker (or fuse) that serves the water heater. 2) Check the high-temperature cutoff in the water heater. Open the panel, and push the reset button. 3) If these steps don?t solve the problem, call an appliance repairperson.

    Take care here - a defective circuit breaker can give a false 240 volt reading - check for the 240 volts across the upper element (i.e. when the 240 volts has a live load on it, not just an open circuit test).
    Also, remember, the upper element has priority over the lower element, and if the water is cold, the upper element will try to turn on and this locks out the lower element (only one element is allowed to heat at any given time). The lower element comes on ONLY after the upper thermostat is satisfied. Therefore if the upper heating element is burned out you will never get any hot water. If you suspect this, TURN OFF THE POWER TO THE HEATER and take a resistance check of the upper element.

Have you tried just direct wiring the heater to your wires from the panel. Turn off breaker, wire up to heater, turn on breaker. If it works you are either wiring the thermostat wrong or the thermostat is defective.

This thermostat is a DPST (Double Pole Single Throw) type meaning it will switch BOTH pairs of wires either ON or OFF. It is a type used primarily for 220 - 240 volt circuits and can switch up to 22 amps of load current. Most heaters will provide a wattage rating and some also provide a current rating as well. Since most electric heat circuits are connected to a 2 pole 15 or 20 amp circuit breaker (or fuses) via #12 copper wires it should work well. If connected to a circuit greater than 20 amps - as long as the heaters connected to the circuit do not draw more than 22 amps will also work fine.

If all is well so far, the continue. The thermostat should have 4 wires. Two of one color, two of another (black and red are common colors). One color group will be the LINE (powered) side, and the other group is the LOAD (heater) side. You should verify WHICH color group is which for best results. The switch will open and close a connection between the LINE wires and the LOAD wires.

The thermostat should be installed in an electrical switch box located on an interior wall at about 5 feet high and not above any heater or heat source. Do not locate it behind a door that swings open, etc. The box should be supplied by a circuit from the electrical panel that will connect to the LINE side color group wires *and* a circuit that will extend from the thermostat's LOAD color group wires to the heater's wire connections / terminals.

If running common #12/2 (for a 20 amp circuit breaker) or #14/2 (for a 15 amp circuit breaker) romex cable from the panel will have the Black and White wires connected to the thermostat's LINE wires and the Black and White wires in the #12/2 or #14/2 romex cable from the heater will be connected to the thermostat's LOAD wires. The ground wires will connect to each other AND a short length of the same size wire should be run from this same point to each: the ground terminal screw of the thermostat and (if using a metal electrical box) to the electrical switch box with a separately purchased green ground screw designed specifically for this purpose. Plastic boxes are not grounded.

Thermostat Line Voltage How to Install or Replace


You either have a new line voltage thermostat or have to replace your old line voltage thermostat. In either case the process is much the same.

1286363.jpg

  1. Make sure that all power is turned off at the breaker panel. Most heaters that use a line voltage thermostat usually use 240v current so the breaker will either be a double pole breaker or you will need to turn off two single pole breakers to kill all of the power.
  2. Check to see which wires are hooked to the breakers. In most cases it will be the red and black wires, but I have seen many times that the white and black wires were used. Often there is no red available when the white is used.
  3. Take out the two screws that hold the thermostat to the junction box. When you get the thermostat out make a note of which wires go to the heater (load) and which wires are coming from the breakers. (line)
  4. If you have a single pole thermostat installed one of the sets of wires may be wired straight through the box or have the line and load wires connected directly in the box. With a double pole t-stat you will have both sets of wires running through the t-stat.
  5. Remove the old thermostat and wire the new t-stat in the circuit with the load wires hooked to the load or heater and the line wires hooked to the wires coming from the breaker. Make sure to get a very good tight connection as resistance loads will heat up quickly if good contact is not made. This poor connection can and will start fires.
  6. Turn the power on and check the heater for heat output.
  7. Turn the power back off and carefully screw the thermostat to the junction box securely. Then you can reapply the power to the circuit.

Now you are up and running with a new line voltage thermostat installed.

Can I change out a Hayward H400ID with an electric heater for the spa only? If so what electric heater product brand would you recommned. Raypak?


Hayward has manuals for each type heater, gas and electric.
http://www.hayward-pool.com/prd/In-Ground-Pool-Manuals_10201_10551_14502_-1___I.htm
Hayward also has contact page, and can probably recommend correct change-over product.

You want to switch from propane to heat-pump type.

There are likely 3 areas of difference. Read each manual and generally look for 1) unit size and capability to match spa 2) pipe connections and sizes 3) Electrical requirement

From electrical standpoint, You need GFCI-protected line from circuit breaker box, or GFCI (arc-fault) breaker. This will prevent electrocution risk around spa.
http://waterheatertimer.org/How-to-wire-GFCI.html

Wire sizes are based on volts and watt-rating of heater.
Each electrical device has rating plate showing volts and watts.
3500 watts divided by 240 volts = 14.5 amps so install double-pole 20 amp breaker and use 12 gauge wire.
1500 watts divided by 120 volts = 12.5 amps so install sinle-pole 20 amp breaker and 12 gauge wire.

I have a large room in my basement where I would like to install four Marly 58" baseboard heaters to work off one thermostat. The units are rated at 1250 watts each for a total of 5000watts. I plan to...


Using the equation I = P/E where "I" is Amps, "P" is Watts, and "E" is voltage, we find that your 5000w circuit will have an Amperage of 20.83. A 22 amp tstat will work, it will just leave you no room for surges. I would suggest splitting the baseboard and using 2 thermostats. Hope this helps

CAN I WIRE A 2 WIRE NOMA NON PROGRAMMABLE THERMOSTAT TO A 240 V BASEBOARD HEATER AND HOW. 2 BLACK WIRES ON THE THERMOSTAT. 3600W@240 VOLT


To the best of my knowledge, Noma does not make a high voltage stat (M# would be more helpful). You most likely have a heating only stat that operates on 24VAC. Also, at that wattage, the wires on your thermostat would need to be a minimum of 12ga.

Problem wiring 240amp baseboard heaters


12 gauge wire sounds under sized for the application. And 20 amp 240 v breakers might be sufficient if you where wiring the heaters separately. But be sure that your wiring is not romex - because romex is an insulator and is not permitted in conduit. I would suggest that you up size your wire to 10 guage and your breaker to 30 amp as well. Then double check your heater wiring connections to insure that they're wired the same throughout.

1 Answer

Heater is not heating up.


First, is this a 120 VAC or 240 VAC heater? 120 VAC heater will usually have one Black & one White wire and 240 VAC heater will usually have two Black wires or one Black & one Red wire. If it is a 120 VAC heater then you need to supply the white wire at the heater with a neutral (white) wire from the breaker panel. If it is a 240 VAC heater then you need to verify that you have 240 VAC at the heater from Black lead to Red lead. If you are not sure about how to do this please have an experienced electrician look at it so you don't get electrocuted and/or burn up your new heater. Hope this helps!

Properly installed electric baseboard heater won't work.


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.
