Lake heating, no drilling required

The principle behind lake heating is to make use of the energy stored at the bottom of lakes. A collector hose is placed on the bottom of a watercourse. Circulating liquid in the collector hose absorbs the heat, which is transferred to a building by the shore. Lake heating reduces energy consumption by up to 80%.

Save up to 80% with lake heating

Save up to 80% with lake heating.

COP is a measure of the lake heat pump’s efficiency – how much you save. From 1 kWh of electricity you obtain 4.6 kWh of heat energy, i.e. a heat factor (COP) of no less than 4.6. This high efficiency level means that you can save up to 80%!

More even heating offers more comfort

At CTC we’ve chosen our own technology that provides much more even heating without the temperature fluctuating up and down. Radiators and floors always maintain a precise temperature.

  • Low investment cost.
  • No drilling.
  • Simpler installation.
  • High efficiency.
  • Thanks to our unique EnergyFlex technology, you have full flexibility to add other energy sources, for example solar.
