The Multifit GasSaver is an innovative product that sits neatly between a boiler and flue and recycles the heat from the flue gases which would normally be expelled into the atmosphere and wasted. It has been proven by independent testing to achieve domestic hot water savings of up to 7% and can reduce the gas used to heat hot water by up to 50% annually*.
How it works
The Multifit GasSaver stores the condensate normally expelled into the atmosphere through the boiler flue. Heat from this condensate is then recycled to preheat water coming into the boiler from the cold mains supply, significantly reducing the amount of gas required by the boiler to heat the water. This means lower energy bills for the householder and greater carbon savings.
