The integrated tank stores thermal inertia/energy. by using heat from the tank when the fire place is not running. The tank installed has coils running through the tank.
Our system makes use of a customized control design which heats up the radiators in the home and automatically switches to heat the tank once the radiators is heated. Heating can also be fixed on the tank while still enjoying heat from the fire place. Heating periods is programmed into a controller to draw heat from the tank when the fire place is not in use.
Once desired temperature of 65-70 deg C is reached, control system diverts heat to the storage tank via 3-way valves.
