COMBINED HEAT & POWERicon-128px-combined


A conventional power plant makes electricity by a fairly inefficient process. A fossil fuel such as oil, coal or natural gas is burned in a giant furnace to release heat energy. The heat is used to boil water and make steam, the steam drives a turbine, the turbine drives a generator, and the generator makes electricity. 

The trouble with this is that energy is wasted in every step of the process—sometimes quite spectacularly. For example, the water that’s boiled into steam to drive the turbines has to be cooled back down using giant cooling towers in the open air, wasting huge amounts of energy.

Instead of letting heat escape uselessly up cooling towers, the idea behind combined heat and power, also know as CHP, is to capture the heat that would normally be wasted in electricity generation and supply it to your buildings as well. Where a conventional power plant makes electricity and wastes the heat it makes as a byproduct, a combined heat and power plant makes both electricity and hot water and supplies both to consumers. Cogeneration (the alternative name for CHP) simply means that the electricity and heat are made at the same time.

CHP units use a fuel source like natural gas or biomass to generate electricity for immediate consumption, whilst the bi-product produced during the generation process (heat) can be used to heat hot water and provide space heating.


A constant source of energy throughout the year, micro, mini and large combined heat and power units are seen as an energy efficient alternative to traditional heating systems. A CHP biomass boiler has the added benefit of additional electricity for site consumption. CHP is one of the most cost-efficient methods of reducing carbon emissions from heating systems in cold climates, and is recognised as being the most energy efficient method of transforming energy from fossil fuels or biomass into electric power.

Adopters of CHP biomass boilers can apply for incentives such as ROCs and the CHP energy tariff and get paid a set amount for every kWh of energy the system generates.


We supply and install the FRÖLING range of CHP biomass boiler units, which are manufactured in Austria and Germany. FRÖLING represents state-of-the-art technology that combines sparkling ideas with technology that has stood the test of time. For five decades they have specialised in the efficient use of wood as an energy source and are a decisive force when it comes to development in this field. Highly efficient and reliable all round solutions make them one of Europe’s leading suppliers

Biomass Combined Heat and Power (CHP) is the perfect zero carbon solution for users with a high heat requirement all year round and are eligible for a number of government subsidies.
