Boiler manufacturer Baxi has unveiled domestic gas boilers that can simultaneously generate electricity and heat for lower carbon output while also adding to the national grid.

The Ecogen micro-CHP (Combined Heat and Power) unit looks similar to a conventional wall-hung gas boiler and can generate up to 1kWh of electricity as a by-product of heat generation.

The device converts 92% of the total energy in the gas into heat or electricity reducing wastage, the company said.

Under the UK Government’s Feed-In Tariffs scheme, each household will receive 10p for each unit of power generated and an additional 3p for each unit fed into the grid.

Field trials show that the system can meet up to two-thirds of a typical household’s electrical needs, the company claims.
