Thermal actuators for stoves and chimneys
When mounted on the exhaust of a chimney, a flap (generally manual flap) is here to regulate the power of fire, and to isolate the house from outside cold temperature, when the fire is off.
An air input pipe is needed at the bottom of the fireplace, in order to provide fresh air from outside, to activate the fire. This pipe must be closed when there is no fire anymore, in order to prevent from cold air flow in the house.
Smoke referral: some modern chimney inserts are equipped with a manual flap on the top of the fire place, in order to force a double combustion of smoke. This decreases the quantity of polluting particles which are emitted to the atmosphere.
Advantages of the bimetal technology:
- Can be used both as thermal sensor and actuator.
- Simple and low cost.
- Energy free.
- Reliable and sustainable.
