Micro combined heat and power

A new type of central heating boiler has recently become available. The boilers are combined heat and power systems which provide free electricity while the boiler is firing.

Combined Heat and Power Systems (CHP)

CHP systems have been in use for some time in Northern Ireland in large scale installations such as hospitals and leisure centres. Domestic sized models are now on the market.

The unit is gas fired and although its primary function is to provide central heating for the dwelling, it also generates about 1kW of electricity while it's running. Householders with these units installed should notice a reduction in their electricity bills.

This reduction will be enhanced if all the free electricity generated by the boiler is used rather than going back on to the grid. Power NI will buy back electricity which is spilled onto the grid but at a cost which is below the supply cost. Installing one of these units will also have a positive impact on the environment as they will reduce CO2 emissions from the property.

Insulate first

You should make sure that your property is properly insulated before installing renewable technologies.
