A Combined Heat and Power (CHP) device simultaneously generates both heat and power and is a mature technology widely used in industry. Recovering the heat from a power generating process leads to high overall efficiencies.
Micro-CHP systems for individual homes are a relatively recent development but units resembling gas-fired boilers can now provide not only heat for space and water heating but also electricity to power domestic lights and appliances.
Micro-CHP is now a relatively straightforward replacement for the domestic boiler and because of the small size can be ‘dropped in’ to most homes.
