Stirling engine CHP systems (Also called Micro Combined Heat and Power (mCHP) systems) achieves high efficiencies by utilizing a state-of-the-art Stirling generator, a highly efficient combustion process, and the industry’s leading water heating technology.
At Helec we provide installation, servicing and maintenance of Stirling Engine CHP systems. Contact us today to discuss your CHP project.
Helec’s Qnergy Micro Stirling engine CHP system uses natural gas or LPG to produce both heat and electrical energy. This 99% efficient system uses the Free Piston Stirling Generator technology that is completely sealed, requiring zero maintenance. The Qnergy mCHP has a similar maintenance cycle as a traditional boiler so there is no need to bring in any additional professionals. The system is designed and sized for light commercial or large residential applications. It should be noted that multiple systems can be “cascaded” together for larger on-site needs.
Maintenance Free generator
Hermetically sealed environment (engine level) – zero maintenance at 60,000 hour cycle

No oil change
High-efficiency engine (up to 37% heat to electricity)
Up to 95% system efficiency
|Low emission and reduced operation costs|
|Low vibration level (engine is suspended using straps)||Ease of implementation in residential buildings|
Gas agnostic engine (external combustion)
Grid frequency independent (worldwide 50/60hz deployment)
Can work on any gas
|Modularity – Cascade ready||Fast expansion|
Qnergy’s CHP Stirling engine is shown in the schematic below. It operates just like a standard boiler generating thermal energy, but generates electricity by using some of the heat created by the natural gas or LPG fuel. The heat energy produced can be used for domestic hot water, space heating, or for heating a swimming pool, hot tub or any other commercial type of application with a thermal heat load demand.
