Reliable heat, even in extreme conditions.

Households use up to 80% of their energy consumption to generate heat. Our smart combination of heat pumps and photovoltaics makes it possible to obtain a large proportion of this energy free of charge from the environment.

Get the most out of your solar heat generation

The intelligent integration between SOLARWATT energy management and Stiebel Eltron products guarantees the highest possible self-utilisation of solar power to reduce the operating costs of the heat pump. As a customer, you can view the current operating data at any time.

What makes our partnership special:

  • Direct communication between SOLARWATT and Stiebel Eltron appliances
  • The thermal energy management system uses photovoltaic and weather forecasts to create customised heat pump schedules for your building. Wherever possible, heat is always generated and stored when solar power is available.
  • Quick and easy connection through an internet LAN connection
  • In addition, the heat pump can directly adapt its output to the available photovoltaic generation, for example even when there is little excess solar power, across a broad spectrum.
SOLARWATT Manager portal shows the power consumption of the heat pump in the household
With the SOLARWATT Manager portal, you can keep an eye on all consumers and quickly find out how much surplus solar power your heat pump is actually consuming.

Replace your boiler with a heat pump with the help of a UK government grant

The government is offering grants of £7,500 off the cost of a heat pump to properties across England and Wales through the Boiler Upgrade Scheme*.

Why heat pumps are also worthwhile for older buildings.

  • The air-to-water heat pumps reliably cover the heat requirement even at low outside temperatures down to -25°C.
  • The heat pump can also be operated efficiently with a higher flow temperature (up to 60°C). This means it can be combined with an existing heating system.
  • Simple and space-saving installation

Heat pumps in older properties

Heat pumps aren't just suitable for new builds. In fact, heat pumps are also extremely beneficial and economical in your existing building.

  • Significant reduction in electricity consumption: from 3,800 litres of oil (equivalent to 38,000 kWh) to 11,000 kWh of electricity
  • Annual coefficient of performance: 3.45
  • The newly installed heat pump has a PV electricity share of 35%.

Advantages of a heat pump

Economical and independent

Generate up to 70% of the heat yourself by using PV electricity and make yourself less dependent on expensive gas and grid electricity.
Icon Eco 96

Sustainable

The required power can be covered to a large extent by solar power from the company's own PV system.

Quiet operation

The WPL A07 air-to-water heat pump, for example, has 32.5 dB(A) at 3 meters from the receiver. By comparison, the rustling of leaves is 35 dB(A).
