Stagnant water
A one-stop-shop for aquathermal energy
Sustainable heating with stagnant water? Yes you can! We design and build the suitable aquathermal installation to sustainably heat using your nearby lake, canal, or moat. Our in-depth thermal simulations determine the thermal capacity of the waterbody to design the best performing and cost-effective plant.
We place a heat exchanger in your waterbody that extracts heat year round
The extracted heat is upgraded to the desired temperature using a heat pump
The heat pumps delivers its heat to the existing or newly developed interior heating system
EXTRAQT is recognized dealer of MultiQ's heat exchangers in Belgium and Luxembourg
EXTRAQT collaborates with Eco-Technix for the installation of closed-loop aquathermal systems
High thermal efficiencies (COP) for maximal CO2-reduction
Hybrid systems possible with air units or gas back-up
Passive cooling possible at sufficient depth
Negligible thermal impact on the waterbody and its ecology when dimensioned correctly
Low investment cost compared to geothermal drillings
Zero visibilty of the entire system
Heat pump output temperatures up to 55°C: compatible with floor heating, convectors, and radiators
Little to no maintenance due to closed system without filters
Heating possible during freezing conditions
