Gas fuelled Combined Heat & Power/cogeneration integrates the production of electrical power for onsite use along with the usable thermal heat, in one single, highly efficient process.
Gas fuelled CHP is still the most commonly used cogeneration technology in the UK and is the most reliable and efficient of all CHP technologies. The technology can be used with Natural Gas cogeneration systems and with LPG/Biogas systems.
Helec design, size and supply a comprehensive range of gas fuelled Combined Heat & Power solutions ranging from 7.5 kWe through multiple sizes up to 1mWe +.
Here at Helec we supply, commission, maintain and service a comprehensive range of industry leading Gas fired CHP systems.

Working with Helec
At Helec we can provide a complete turnkey Combined Heat & Power serviced solution bringing peace of mind to fully manage your project from start to finish including;
Installation & commissioning
Service & Maintenance
At Helec Limited we have our own manufacturing facilities so our build teams are able to construct your plant room off-site in order to reduce the need for any sensitve hot works on your project or within your premises. This helps minimise disruption to in-use active premises and decreases the time needed to provide practical completion for most buildings construction projects.

Why Gas Fuelled 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 grid produced electricity where vast amounts of thermal heat is unfortunately disperced and ‘wasted’ to atmosphere.
In today’s 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 “waste heat” rising from power plant cooling towers, dramatically reducing the plant’s generation efficiencies (see below)
By using the ‘waste heat’, gas CHP units can reach overall 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.
