Wiring 240 Volt Electric Heater Thermostat

Adding a 240 volt baseboard heater usually requires a new 20 or 30 amp double pole circuit breaker and new circuit wiring to supply one or more heater units.

Wiring 240 volt electric heater thermostat.

A 240 volt thermostat doesn t use neutral wires and as such all wires are hot. It s a non programmable thermostat that s simple to use. Both of these service wires come in the panel together with a ground wire typically the ground is a whole lot of strands that surround the hot wires. A neutral wire isn t utilized within this circuit.

Using a wire connector connect the hot supply wire to the thermostat wires. More about wiring an electric heater. Electrical wiring for a electric heater. Electricians generally install 240 volt heaters since they use lower amperage and are more energy efficient than 120 volt heaters.

A wall mounted thermostat is recommended for optimum performance. Always turn off power at the circuit panel before attempting any electrical work. How to wire a 240 volt single pole thermostat. The 240 volt baseboard heater may only be connected to a 240 volt supply with a double pole circuit breaker in the electrical panel.

240 volt is typically more energy efficient and provides a lower energy bill compared to 120 volts because of even or balanced circuit utilization. Most baseboard heaters will require a dedicated circuit. When wiring a 240 volt heater a double pole thermostat should be used. Simultaneous wiring of dual heating elements 9000 watts each of 4500 watts and thermostats for 240v and 230v electric water heater.

230v and 240v continues dual element electric water heater thermostat wiring. A double pole thermostat is designed to shut off power to. Connect the remaining thermostat wire typically marked t1 or load to the same color supply wire feeding the baseboard heater. This is a dedicated circuit that serves only the heater s.

Wiring for a 240 volt single pole thermostat is similar to that for a double pole but in this case one of the hot wires will simply bypass the thermostat and pass onward to the baseboard heater. Check out our voltage blog pos. Electric baseboard or wall heaters and their thermostats should be wired to their own dedicated circuit to prevent overloading. 240 volt wiring on the flip side may not require a neutral white wire.

The size of the circuit will depend on the total watts that will be required. 120 or 240 volts. Failure to meet proper electrical standards can result in electrical shock or fire. The electric baseboard heater is the number one choice for low cost installation and the quiet operation makes it the preferred heater for bedrooms.
