Mains wiring is dangerous and can kill you if you do not know what you are doing. For your safety I suggest you get a electrician to wire up your heaters.

SOURCE: wireing three units together

yes, you did a good job. Sounds like you paralled them. Which is right buuuut what size are these heaters. Add the wattage of all of the heaters and divide by 120 and that is how much current you will be using. On a 20 amp breaker you can only pull 16 amps safely. I think you will be way over unless the heaters are 600 watts each. You are allowed 1800 watts on a 20 amp circuit.

SOURCE: 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.

Hello there
It sound alright but You should draw out a wiring diagram on paper first before you tackle the job that way you know you're doing it right.

Good luck Dickson

Fan on gas wall heater shuts off and on every 3 minutes, but the flame is on the entire time.


It always helps to add the model number of the item you want help on. However if it's like the newer units, the fan operates whenever the heater wall has reached a high enough temperature and shuts off when the heater cools off. It is not wired into your thermostat or electrically wired to the heater. It does that with a temperature driven fan switch in a little junction box mounted to the heater. Normally when that box gets hot because the heater is on the fan comes on, when it cools off the fan goes off. The junction box will have an ac cord coming out of it. If this fan switch junction box is not properly mounted it could be getting cooled off when the fan starts and then shuts itself off. After it heats up again it starts the fan. The other possibility is the temperature based fan switch is failing and needs replacement. See link.

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 install a junction box before my water heater junction box?


Junction box is fine.
Must be accessible and not hidden inside wall.
http://waterheatertimer.org/Color-codewire.html
http://waterheatertimer.org/How-to-select-right-wire-nut.html

43 feet is not over 100 feet, so wire size can stay same.
Recommend 30 amp breaker and 10 gauge wire for 4500 watt water heater.
If circuit has 20 amp breaker and 12 gauge wire, recommend 3800 watt elements.

Is the lower element suppose to have two legs of 120 to it? Or do i need to move a wire up top to make it 240? as it is on top element.


You have water heater with two elements.
Two-element water heaters are 240Volts.

1) Lets talk about what makes a 240Volt circuit
See basic water heater circuit:
http://waterheatertimer.org/B220C.html

Open link, and illustration at top of page is your water heater circuit

Notice that two insulated wires come from the circuit breaker and go to the water heater.
These two wires are 120volt each. When these two 120Volt wires combine, they create 240Volts
These are called hot wires because they come from the hot busbars.
There is also a bare copper wire that comes from neutral busbar.
The bare copper wire is a safeguard, and is not necessary for the 240V circuit to work.

Inside each circuit breaker box is 1 neutral busbar, and 2 hot busbars.
Open image below, and it shows typical residential breaker box
http://waterheatertimer.org/images/Inside-Main-Breaker-Box-420.jpg

In a residential home, each circuit takes two wires to complete the circuit.
For 120Volt circuit, you need 1 neutral wire and 1 hot wire to complete the circuit. These are usually a black and white wire. The bare copper wire is a safeguard.
For 240Volt circuit, you need 2 hot wires to complete the circuit, and each hot wire comes off a different busbar. These can be a black and white wire, and sometimes a black and red wire. The bare copper wire is a safeguard.

With a 240Volt water heater the two hot wires connect to the black and red wires located on top of water heater.

2) Let's talk about wiring inside a water heater.
http://waterheatertimer.org/images/WH-w-combined-530.jpg

Open image on link above, and it shows your 240volt water heater wiring.
The 2 hot wires from breaker box connect to the red and black wires on top of heater.
Inside each water heater, the wires are color-coded and will appear the same, or nearly the same, as shown on link above.
As long as your wiring appears like the image, and the hot wires from breaker box connect correctly, and the circuit breaker is working fine, then your water heater will work.

Add a comment any time.

No hot water


Electric water heater can be repaired by homeowner.

Four things can cause NO hot water:
1) ECO red reset button tripped. Remove top cover on water heater, push red reset button on thermostat. Put insulation and cover back over thermostat.
2) Circuit breaker is tripped, circuit breaker bad, or wire loose in breaker box. Turn breaker on-off and listen for crackling or fizzing sound, and burned smell. Test breaker for 220Volts. Test top two screws on upper thermostat to see if water heater has electricity.
3) Bad upper thermostat. Replace upper thermostat.

4) Bad upper element. Test upper element.

Do you hhave a wireing picture or plan to wire the load center


Here are links that show basic wiring inside a breaker box.

Please look at the images.
If you need more help, answer back and we'll go to the next step

http://waterheatertimer.org/240-v-water-heater-circuit.html
http://waterheatertimer.org/Circuit-breakers.html
http://waterheatertimer.org/Color-codewire2.html
http://waterheatertimer.org/Figure-Volts-Amps-Watts-for-water-heater.html

Breaker size:
15 amp breaker connects to 14 gauge wire
20 amp breaker connects to 12 gauge wire
30 amp breaker connects to 10 gauge wire
Home Depot and Lowes have a breaker and wire size size chart next to wire cutting machine
These stores have guys who know the basic breaker size for your big appliances
Each appliance has a name plate showing wattage and voltage.
The wattage tells you what size wire.
The voltage tells you what size breaker and whether you need a 120V breaker or 240V breaker.

To lay out your home wiring:
The kitchen microwave needs a 20Amp 120V 'dedicated' line that goes just to the microwave.
The rest of the kitchen plugs are served by another 20 amp 120V breaker
When laying out rest of house, figure how much wattage might be used in an area.
For example the den might have a big 500Watt TV, and 2 ceiling fans and 4 lights.
Add up the wattage and decide how many plugs and switches you want on each breaker.
Now let's say you have a 20Amp breaker which can carry 1920 Watts for the den.
Inside the breaker box you have a 12 gauge wire for the 20 Amp breaker.
The 12 gauge wire has a black, white and bare ground.
The black connects to breaker. The white and ground connect to Neutral busbar.
The 12 gauge wire leaves the breaker box and goes to the first box in the den.
This box is your junction box.
The junction box can be a switch box or a ceiling light box.
You cannot have any junction boxes that are covered by drywall.
Junction boxes must be accessible. All boxes must be accessible.
For example, you choose a ceiling box for your junction box.
The junction box is also the same box your ceiling light connect to.
From your junction box, you branch off a wire that goes to next box.
And then a wire branches off next box and goes to next box. And so on.

Wiring a programmable thermostat for baseboard heater


The red and black is power and neutral. Green is just for the ground and that should tie into the ground wire for breaker or power wire .
The 2 black wire from thermostat should tie into the two red and black wire from your heater.
Just imagine you are wiring 1 heater to thermostat and just add the the next heater the same way
