Aquathermally heated medieval castle
Castle de Merode in Westerlo now uses a 50 kW water-to-water heat pump connected to a closed-loop exchanger in its moat. The system operates in hybrid mode with the existing gas boiler and CHP, reducing reliance on fossil fuels while showcasing aquathermal energy use in a historic building
Flexdrill: The clean heating catalyst
Flexdrill is a lightweight, trailer-mounted drilling platform that simplifies and lowers the cost of installing ground-source heat pumps. Operable by technicians, it can drill 200 m boreholes from just 1 m² surface area in a single day, removing the need for large rigs and specialist crews.
The thermoroad – full-scale demonstration of geothermal 5th generation district heating and cooling combined with sustainable urban drainage
The Thermo-road is the world’s first road-integrated thermonet within a Sustainable Urban Drainage System, combining geothermal exchangers and stormwater retention. It supplies renewable heating and cooling to 12 homes via heat pumps, recovers wastewater heat in winter, and includes borehole
Making heat pumps attractive in education
The shortage of skilled labour and the lack of attractiveness of service technician jobs for young people will result in a reduction in the quality
Aquathermally heated heritage building
Les Les Jardins d'Eau d'Annevoie – 1758 is a historic heritage building surrounded by a moat/pond, an ideal source for aquathermal energy where heat is extracted from surface water.
DC Heat Pumps with Cross Connected PV
This 750kW heating, cooling, and domestic hot water plant integrates a DC electrical system with dedicated solar power. The system simplifies installation, reduces costs, and offers a highly resilient solution, ideal for facilities like hospitals
CoBra – The Cottbusser Brayton Heat Pump
In this project, we have designed, built, and commissioned a heat pump named “CoBra” which operates based on the reversed Brayton cycle....
Heat the streets
Heat the Streets is the UK's pioneering high-density ground source heat pump (GSHP) project, partly funded by the European Regional Development Fund (ERDF). It was delivered in rural Cornwall, UK.With the progress towards the UK's net-zero targets for domestic heating being significantly behind
PHAC system
To use the electricity when it’s available AND locally/off grid (PV-panels), to reduce the amount of electricity needed (run the heatpump only for cooling) and last-but-not-least to reduce the load on the electricity grid.
Zero Energy Homes Arnhem
In Arnhem 96 homes have been renovated to Zero Energy level by adding a new outer shell including insulation, replacing the windows and completely replacing all technical installations by our Nathan Energy Module.
