Heat pumps

Heating with ambient energy works in existing buildings almost every time, provided the system is properly sized for the house. That is exactly where we start.

New build or existing house, what matters are heat demand, radiator surfaces and flow temperatures. We survey the building, size the heat pump accordingly and tell you honestly if something about the building should come first.

With us, heating and electrics come from the same company: our team handles the hydraulic integration including plumbing and heating work, our electricians the connection, the distribution board and the registration. If a photovoltaic system runs on the roof, we match the two so as much of your own power as possible ends up in the heating system.

What we take care of

  • Building survey and honest sizing for the heat demand
  • Installation including hydraulic integration by our own teams
  • Electrical connection, distribution board and grid registration
  • Matching with photovoltaics and storage
  • Commissioning and instruction

Funding and tax

The federal government supports switching to a heat pump through KfW (programme 458, heating subsidy for private individuals): a base subsidy of 30 percent of eligible costs, combinable with further bonuses, for example when replacing an old oil, gas or storage heater, and tiered by household income.

For owner-occupiers, combined funding is generally capped at 70 percent, with up to 80 percent possible for lower incomes, and eligible costs are capped at 28,000 euros for the first residential unit. As of September 2026; the rates were last adjusted in July 2026 and may change further. We check the currently valid conditions for your building, but we are not a substitute for tax advice on your individual case.

Where we work

We mainly work in Gechingen, the Calw area and Pforzheim, with projects in most towns within 25 kilometres, from Althengstett and Weil der Stadt via Bad Liebenzell, Wildberg and Herrenberg to Böblingen, Sindelfingen, Renningen, Leonberg and Nagold. Our regular service area is around 50 kilometres, reaching the greater Stuttgart area; larger projects are possible across Germany by arrangement.
