  • Ground Source Heat Pumps

    In many buildings Ground Source Heat Pumps (GSHPs) provide an efficient solution for heating and cooling. Using low temperature latent heat which exists naturally below ground, GSHPs provide solutions by harvesting and transferring this energy for the benefit of the built environment. It is important to understand the feasibility of GSHP prior to designing a system. This guidance note has been ...

  • Exergetic and sustainability performance assessment of geothermal (ground source) ejector heat pumps

    Although ejectors have been used in cooling/refrigeration and Heat Pumps (HP) applications for a long time, utilisation of Geothermal Ejector Heat Pump (GEHP) with Ground–Heat Exchanger (GHE) is a new idea, which has recently appeared in the literature. In this study, we model a GEHP system with a GHE in terms of exergetic aspects and apply our model to this system in the heating mode. The system ...

  • 24kW Ground Source Heat Pump In Essex - Case Study

    The space heating and hot water for this property was previously done by an oil boiler. The client was considering a ground source heat pump in order to lower running costs and benefit from tariff payments under the Renewable Heat Incentive (RHI). Better Planet carried out a room by room heat loss calculation. This is required in order to size the heat pump ...


  • Zoo-technical application of Ground Source Heat Pumps: a pilot case study

    Ground Source Heat Pumps are energy-efficient HVAC systems usually adopted in residential and commercial buildings. However the control of the thermal environment is required not only in spaces occupied by people, but also in intensive breeding farms, in order to maintain healthy conditions and to increase productivity. In the Italian livestock breedings, heating is usually provided by means of ...

  • Heat recovery from wastewater

    Heat recovery from gray water is particularly important in water-intensive industries such as pulp and paper plants, dairies and breweries. Rather than flushing used water down the drain, consider whether a heat exchanging system can help you put that energy to work in your process again. Most plant operators arc aware of the need to save money and reduce the environmental impact of their plant ...

  • Getting an air source heat pump from Better Planet – from first discussion to finished project

    Initial contact The initial contact is often on the phone and we try to establish if an air source heat pump makes sense from a financial and technical point of view. Heat pumps makes sense for most new built projects. For retrofits, heat pumps makes most sense for properties not connected to the gas grid. If you are connected to the gas grid, ...


  • Harbin daoli - District Heating, China case study

    In cooperation with ABB A/S Skovlunde and APV A/S Kolding DESMI A/S replaced large parts of the heating network in Harbin in China. Daoli is one of the seven districts of Harbin, the largest city in North East China with approx. 11 million inhabitants. It is known for its bitterly cold winters and is often called the “Ice City” – so therefore the city welcomed this ...

  • Opening markets for CSP – the industrial heat application

    Heavy industry can be a viable secondary market today for CSP producers, but questions remain on whether start-up costs are justifiable for industrial users, and how reliable CSP can be for processes that can't pace production by the sun. Solar thermal heat implies steam, and industries that need steam include refining, food processing, wood-working, desalination and chemicals, among others. ...

  • What can you achieve with a solar system and battery?

    People often ask us about energy self-sufficiency. Just how hard is it to get to that point where you no longer have to pay a large corporation each time you turn on the kettle? This will depend on your usage patterns but for most people, a mix of renewable systems is the best option. We’ve taken a look at Gabriel’s home renewable systems as an example. Perhaps unsurprisingly, Gabriel ...
