The Baxi Ecogen dual energy system from heating manufacturer Baxi has won two Homebuilding & Renovating Product Excellence Awards 2011.
The Ecogen won both the Heating and Plumbing category and the Green Award. The judges said that whilst it had “obvious eco credentials it deserves to be taken seriously as a mainstream heating and plumbing solution.”
The Baxi Ecogen Dual Energy System is a micro-combined heat and power (micro-CHP) wall hung gas boiler, whichgenerates both electricity and heat from the same source close to where it is to be used. The first boiler of its kind available on the market, it is an easy replacement for a conventional gas boiler.
For electricity generation, it uses a Stirling engine that is heated by burning gas. Helium inside expands and contracts to move a piston up and down between a copper coil, generating up to 1kW of electricity at 50Hz single phase. Any electricity that is not used in the home can be exported back to the grid. It is MCS certified so is eligible for the Government’s Feed-in Tariff.
