I have a wood burning furnace in the house that I just purchased the problem is that there is not a thermostat on the furnace I need to put one on how do I go about wiring a thermostat into the blower and will it need an off/on switch.

Also do you know of any good places to purchases thermal switches and blowers

Thanks

I am not completely sure what you are trying to do. Take a look at https://www.askmehelpdesk.com/heatin...ing-36908.html and post back with more details.

I am looking to add a new blower onto the wood burner that has an older worn out blower installed on it and installing a new thermal switch(thermostat) onto the wood burner to control when the blower comes off and on how do I go about wiring the switch to the blower I am not using any of the wiring or features from my heat pump thanks

Any cheap old thermostat should do, but you will need a transformer and a relay. You might look at ones meant for electric baseboard heaters. They are designed for directly switching even higher loads and don't need a transformer.

Otherwise you run one wire from the transformer to the R terminal on the thermostat. Run another wire from the W terminal to one terminal of the coil of the relay. Run a third wire from the second terminal of the transformer to the second terminal of the coil to complete the circuit. Then wire the fan to the load side of relay and a hot wire from the house to the line side, plus the other fan lead to the house neutral. When the thermostat calls for heat, it will close the contacts on the relay starting the fan.

I think that what aircraftfixer is referring to is a thermostat that goes in the wood burner to turn the blower on when its hot and off when the fire goes out, so that cold air is not being circulated. I think that these are usually called limit switches, similar to what's used in forced air furnaces to turn the blower on and off.

Maybe so. You can buy all sorts of motors and switches at wwwmouser.com or www.meci.com with no hassle about model numbers for what you are using it in.

Quite right, but a novice electrician my not understand.

This would be the most efficient way to do the job. On the downside, the room temperature will be very difficult to control and the homeowner will need to pay attention to dampering down the fresh air for the fire to get things a bit better regulate
