Eteck

Eteck is the largest sustainable heat supplier in the Netherlands. The company supplies sustainable heating and cooling to homes and businesses, drawing on locally available renewable energy sources rather than a single technology. Its technical portfolio spans ground source heat (geothermal), air source energy, surface water thermal energy, solar energy, and recovery of sustainable residual heat.

Beyond heat supply, Eteck designs, realises and manages energy projects end to end, covering every phase of delivery and tailoring solutions to local conditions. This includes the design and management of energy infrastructure, with district heating forming a core part of its activity across the residential, commercial and sustainable energy infrastructure sectors.

The company operates in the Netherlands and employs approximately 150 professionals. Its stated focus is on accelerating the energy transition towards carbon-neutral energy, with work concentrated on decarbonisation of heat supply. The team is described as combining comprehensive expertise across project phases with solutions adapted to the specific conditions of each site.
