Micro CHP

Micro-CHP is a specific form of CHP designed for individual households. As a replacement for a standard domestic gas boiler, it generates power mainly for consumption in the home but also for expert, alongside heat for space and water heating.

The Baxi Ecogen is the first widely available wall-hung domestic micro-CHP boiler in the UK. The boiler produces up to 1 kWe of electricity per hour, to be used throughout the owner’s home. Electricity that doesn't get used can then be sold back to the local network. Micro-CHP units are also included within the Government’s Feed-in Tariff scheme. This means that owners of a unit receive an additional 13p on top of the standard sale price for each kilowatt hour (Kwh) of power they sell.

The benefits of local electricity generation and use mean an Ecogen unit can reduce yearly fuel bills by up to £600 and cut household carbon emissions by up to 40%. Servicing costs and intervals of every 12 months are similar to a standard boiler. The units only requires a single cable electrical connection and can be connected to an existing electricity circuit ensuring installation costs are minimised.

The Baxi Ecogen is a type of Stirling engine micro-CHP unit. Numerous other types of Stirling, alongside fuel cell and Organic Rankine Cycle, micro-CHP units from a wide range of other manufacturers are currently in development or nearing commercialisation.
