Micro CHP (Domestic Combined Heat and Power)

Micro CHP (Domestic Combined Heat and Power)

A boiler that generates electrical power

A Micro CHP boiler looks very similar to a standard combination (combi) boiler, although most are a little larger in physical size. They can be fitted to most homes and existing traditional heating systems and are usually powered by Gas or LPG.

The main function of Micro CHP is to provide heat and hot water with some generation of electricity – it should be noted that these boilers only generate electricity whilst the heating or hot water is switched on.

They do qualify under the Feed-in-Tariff scheme (FiT), where you can receive payments from the government for 20 years for any electricity they produce.

Unlike solar panels, a Micro CHP can produce electricity at any time of day or night. It doesn’t rely on building orientation and is often generating electricity at peak demand times such as while you’re using power within your home, cooking, washing, ironing etc.

The electrical connection is often a simple operation, using a single three core cable to connect to the domestic electrical circuit within your home.

Research from the Carbon Trust found that Micro CHP is best suited to larger homes with three bedrooms or more, or older houses of solid brick construction, where the inhabitants require the heating systems to operate for many hours at a time rather than intermittently.

Manufacturers claim replacing a band G gas boiler with a Micro CHP can save up to £650 per year based on a running time of 2000 hours, consisting of savings on gas, income from the FIT and a reduced electricity bill due to self-generated electricity. The cost of a Micro CHP installation varies depending upon chosen manufacturer, the Co-operative Energy Saving team will suggest the best options for you.
