How do you wire a thermostat to two baseboard heaters?

Connect the two wires bringing power from the breaker panel to the two “Line” terminals. Connect the two wires carrying the power to the baseboard heaters to the two “Load” terminals on the thermostat. Connect the two bare ground wires together using a wire nut. Install the thermostat in its box.

What is the maximum number of baseboard heaters that can be connected to a single thermostat?





A 240-volt circuit running on a 20-amp, double-pole breaker, can have any combination of heaters up to 3,840 watts. For example, using just one thermostat, you can install: Two 1,500 watt heaters, or. Three 1,000 watt heaters, or.

Are baseboard heaters wired in series or parallel?

All heaters must be wired in parallel. You can either do that by connecting each heater to the thermostat directly, or by connecting each heater to the next — just be sure that each heater is connected to the source wires.

Can I wire a double pole thermostat as a single pole?

Quote from the video:
Quote from Youtube video: So when I wire up my new thermostat which is going to be a double pole thermostat. These two wires here are going to make together along with these two wires they're going to make together.

Can you daisy chain baseboard heaters?

In most all cases, multiple baseboard heaters can be connected together if the total operational amperage does not exceed the wires and circuit breaker’s capacity. If the heater is too large it must be wired on a separate circuit.

How many 240V baseboard heaters can I put on one circuit?





If we have a 240V circuit, we can connect up to three 1,500 W baseboard heaters. That’s because its net amp draw is 3 x 6.25 A = 18.75 A. This is less than 20 A. That means that we can connect three 1,500 W heaters, netting a total output of 4,500 W, if we have a 240 V circuit.

How many wires does a double pole thermostat have?

four wires

A single-pole thermostat has two wires, while a double-pole thermostat will have four wires.

How do I know if I need a single pole or double pole thermostat?

Quote from the video:
Quote from Youtube video: For a double pole thermostat you will have four wires two lines and two loads. The difference between these is that single pole thermostat doesn't have a true off setting.

What is difference between single pole and double pole thermostat?



Both are types of line voltage thermostats, which typically control radiant, convection or resistance heaters. The difference is all about the off setting — or a lack of one. Double pole stats have a true off setting. Single pole thermostats don’t.

How do you wire two heaters in parallel?

Connecting the heaters in parallel means that essentially the two wires coming from the power source (the thermostat) go to the two ends of the first heater, and the same two wires then continue on and are connected to the two ends of the second heater as well.

Can wires touch baseboard heaters?

Electrical codes typically do not prohibit installing heaters below wall outlets, but most heater manufacturers recommend against it. The concern is that a cord plugged into the outlet will drape down onto the heater.

How many watts is a 6 foot baseboard heater?



1500 watts

Generally, for 120V and 240V heaters, 3 feet will produce 750 watts, 4 feet will produce 1000 watts, 6 feet will produce 1500 watts, and 8 feet will produce 2000 watts.

How much does it cost to run a 1500 watt heater for 24 hours?

Example (you can use an electric heater running cost calculator below for different wattages/kWh prices): If we assume the price of electricity is $0.1319 per kWh, a 1,500-watt electric space heater will cost; $0.20 to run per hour. $4.80 to run per 24 hours (day).

Do baseboard heaters use a lot of electricity?

Is baseboard heating expensive? In general, electric baseboard heaters use more electricity than an electric heat pump. This means higher electric bills, especially in the coldest winter months when they’re working overtime to keep your home warm.

How do you tell if your baseboard heater is 120 or 240?



Just look and if you see one black wire coming in and one going out, it’s a 120-volt heater. If you see two wires coming in — one black and one red — and two wires of the same colors going out, it’s a 240-volt heater.
