CHP – Combined Heat and Power

Combined Heat & Power (CHP) is the simultaneous generation of heat and electricity from the one piece of equipment. In much the same way as heat is captured from the engine of a car when the fan heater is turned on, heat that is usually lost in the power generation process is captured and used as heat for space heating and hot water for example.

By capturing heat that is usually wasted, CHP results in much higher running efficiencies (in some cases greater than 99%), generating significant carbon and energy savings for the user.

These CHP units are great for the following applications:

  • Apartment Blocks using centralized heating systems
  • PART L and NZEB compliance for Apartment Blocks and Commercial buildings
  • Nursing Homes benefit greatly due to the constant hot water demand
  • Commercial Buildings with constant heat loads
  • Large residential buildings
  • Gyms with heated swimming pools
  • Hotels also benefit greatly from using CHP as they have a constant requirement for heat particularly hot water.

  • Glenergy has been supplying CHP units in Ireland for over 15 years and has a large number of reference sites. Click here to see a list of CHP reference sites.

    Glenergy supplies a number of CHP options including the Dachs Micro CHP unit and the larger 2G range of CHP equipment. We have a CHP solution for every scenario. Read more below about our various CHP options.

    The DACHS 2.0 Micro CHP


    The Dachs is a unique state-of-the-art micro CHP unit based on a natural gas, LPG fuel oil or bio diesel fuelled internal combustion engine. Manufactured in Germany by Senertec The one-cylinder four-stroke engine has a capacity of 580 cm³ and was designed to achieve maximum reliability with minimal maintenance.

    Operating consistently and successfully across Europe, the Dachs is proven technology and has become the number one choice in micro CHP. SenerTec and its partner network have installed over 36,000 units worldwide. There are over 100 Dachs CHP units operational in Ireland.

    Together with the storage tank and the hot water module, the Dachs forms a supply centre for heat and hot water. It charges the tank up to a defined temperature and makes energy available for heating and hot water. Once the tank has been discharged to a defined temperature, the Dachs is activated again and recharges it. Part of the storage tank is always reserved for hot water generation. The heating system cannot use this part, so priority is always given to hot water when required.

    2G CHP

    The g-box is a gas fuelled CHP plant by 2G based in Germany. The g-box CHP has an electrical output range of 20 to 50 kW. It is a compact, ready-for-connection CHP module. The g-box CHP not only works highly efficiently, but thanks to a completely enclosed sound cap, it is also very quiet and therefore also suitable for noise-sensitive areas. Thanks to calorific value utilisation, both the g-box 20 and the g-box 50 reach efficient levels of over 100 percent.

    The g-box at a glance.

    • Natural gas CHP range with an electrical output of 20 to 50 kW
    • Runs on natural gas or biomethane; g-box 20 also with liquid gas
    • Ready-for-connection, super-quiet compact module
    • Very economical with high thermal efficiency thanks to calorific value technology (as standard)
    • Long running times, reliable and low maintenance
    • Modular assembly allows insertion into narrow buildings
    • Completely water-cooled, no air inlet or outlet required, thus reducing installation costs
    • Energy efficiency class A++ (according to 2010/30/EU)

    The g-box is suitable for larger apartment blocks, commercial buildings, or entire housing complexes with heating consumption of at least 120,000 kWh or at least 12,000 litres of heating oil a year. Typical areas of use for the g-box chp are:

    • Apartment buildings
    • Hotels
    • Nursing homes
    • Hospitals
    • Schools
    • Shopping centres
    • Swimming pools
    • Office buildings
    • Housing complexes
