Gas fired CHP/cogeneration integrates the production of electrical power along with the usable thermal heat, in one single, highly efficient process.
Gas fired CHP is the most commonly used cogeneration technology and is the most reliable and efficient of all CHP technologies. The technology can be used for natural gas cogeneration systems and with LPG systems.
Helec design and supply a comprehensive range of gas fuelled Combined Heat & Power units ranging from 6 kWe through multiple sizes up to 1mWe.
At Helec we provide installation, servicing and maintenance of Gas fired CHP systems. Contact us today to discuss your CHP project.

Working with Helec
At Helec we provide a complete CHP service and can manage your project from start to finish including;
We have our own manufacturing facilities so we can create your plant room off-site to reduce the need for hot works at your project or premises. This helps minimise disruption to in-use premises and decreases the time to completion for building projects.

Why Gas Fired CHP
Gas fuelled Combined Heat & Power (CHP) Cogeneration integrates the production of electrical power along with the usable thermal heat, in one single, highly efficient process.
A CHP primarily generates electricity whilst also being able to absorb and use the thermal heat that is produced in this process.
The thermal energy is created by the engine’s water cooling jacket heating up, this is transferred away from the engine via a heat exchanger and pumped out to a thermal store, or a buffer vessel before going on to supply the buildings heating circuit, or pre heat the domestic hot water system. The returning ‘cold’ water is reheated in the engine jacket again and the process is repeated continuously whilst there is sufficient demand (see below).
This is the same principle as used by a large power station to generate electricity but is more than twice as efficient because instead of rejecting the heat to atmosphere, the CHP engine heat is transferred to the buildings services.
This contrasts with conventional ways of generating electricity where vast amounts of thermal heat is simply wasted. In today’s coal and gas fired power stations, up to two thirds of the overall energy consumed is lost in this way, often seen as a cloud of steam rising from power plant cooling towers dramatically reducing the plant’s generation efficiencies (see below)
By using ‘waste heat’, gas CHP units can reach efficiency ratings in excess of 80%. This compares excellently in comparison with the efficiency of gas power stations, which in the UK range between 49% and 52%. Coal-fired plant fare less well with an efficiency of around 38%. The financial benefits of a single fuelled co-generation process are also complimented by a series of environmental advantages with reduced C02 emissions being recognised by local authorities and government bodies.
