Combined Heat & Power (CHP) units generate electricity on-demand at the point of use, using natural gas, hydrogen blend, LPG or biogas. They can power our future heat generation plant such as heat pumps with low cost, low carbon electricity, while reducing the burden placed on the electricity grid. The ‘free’ waste heat by-product from power generation is also used within the building or heat network, further reducing the operational cost of the heating system.
In this table you will see all the relevant key data for the CHP product range:

Low carbon power generation on demand – even when the wind isn’t blowing and the sun isn’t shining!
Security of supply and protection from escalating electricity tariffs
Modulating output to match site demand
Suitable for new build and retro-fit into existing buildings with a gas supply connection
Where a gas connection is available, CHP offers significant CO2 footprint and cost savings in new-build and existing buildings. Using a high efficiency, low NOx emission gas engine, CHP’s generate low carbon, low-cost electricity at the point of use and on-demand. Unlike intermittent renewables, CHP can react to the buildings consumption of electricity and modulate generation in real-time according to site loads, tariff signals and grid carbon intensity. Hence, CHP saves carbon and costs by displacing the consumption of grid electricity.
Inherently, waste heat is produced as a by-product of power generation. This ‘free’ heat is captured as heated water and is used within the building to reduce the output of the boiler and reduce the boiler’s consumption of gas or electricity. In a hybrid energy centre, heat pumps are also a customer for CHP electricity and the two appliances become consumer and producer within a Prosumer building. This helps to protect the grid from some of the impact of large-scale electrification of heat production and protects the owner/occupier from extreme electricity tariffs.

A Combined Heat and Power (CHP) unit is a type of energy generation system that generates both electricity and usable heat at the same time, using natural gas, hydrogen blend, LPG or biogas. It generates electricity on-demand at the point of use and the 'free' waste heat by-product from power generation is used within the building or heat network, further reducing the operational cost of the heating system.
The key features and benefits of CHP technology include:
- Low carbon power generation on demand, even when renewable sources like wind and solar are not available
- Security of supply and protection from escalating electricity tariffs
- Modulating output to match site demand
- Suitability for new build and retrofit into existing buildings with a gas supply connection
- Integration with hybrid energy centres and heat pumps to maximise efficiency and cost savings
CHP generates low carbon, low-cost electricity at the point of use and on-demand, unlike intermittent renewables. It can react to the building's consumption of electricity and modulate generation in real-time according to site loads, tariff signals and grid carbon intensity. This helps displace the consumption of grid electricity, saving carbon and costs. Additionally, the 'free' waste heat produced is captured and used within the building, reducing the output and consumption of the boiler.
EC Power offers a range of CHP units with the following key statistics:
- XRGI 6 Low NOx: Modulation range 4.5 - 6.0 kW, Heat output 12.5 - 14.6 kW (non-condensing), 14.3 - 16.8 kW (condensing)
- XRGI 9 Low NOx: Modulation range 4.5 - 9.0 kW, Heat output 12.4 - 20.1 kW (non-condensing), 14.2 - 23.3 kW (condensing)
- XRGI 15 Low NOx: Modulation range 10 - 15 kW, Heat output 26.1 - 31.4 kW (non-condensing), 29.3 - 35.9 kW (condensing)
- XRGI 20 Low NOx: Modulation range 10 - 20 kW, Heat output 26.1 - 38.7 kW (non-condensing), 29.3 - 44.7 kW (condensing)
The EC Power CHP units are compatible with BREEAM 2018 Pol 02 Credits, providing 2 credits towards the assessment. They are also compatible with the "Flexible Operation" approach in SAP 10.2, allowing the CHP to react to site demands, tariff signals and grid carbon intensity to optimise energy usage and savings.
