Ravenheat has launched its Energycatcher, an environmentally friendly unit which can reduce cutomers' gas bills. While modern boilers are increasingly efficient, one source of waste heat and pollution that has not so far been addressed is the heat which escapes through the boilers' flue. With the boiler running, flue gases can reach up to 60ºC. Energycatcher catches the gases and flow them over a heat exchanger. The 'waste' heat is transferred to the water and reused.
