Renewable heat as part of the energy system

A heat pump can combine environmental energy and solar power in a coordinated setup for heating and hot water.

Benefits

A solution designed around the project

Plan electricity and heat together

Building, heat demand and existing systems are assessed together with electricity generation.

Designed rather than guessed

The concept is based on the building, technical conditions, demand and intended use.

Interfaces included

Existing systems and sensible future components are considered from the outset.

Clear next steps

Assessment, planning and implementation are divided into transparent project phases.

Description

The right solution starts with the building

Heat load, distribution, location, noise, hot-water demand and electrical infrastructure influence planning.

Photovoltaics, storage and energy management can coordinate operating times and self-consumption more effectively.

  • Building and location assessment
  • Coordination of heat demand and system output
  • Integration with PV and energy management

Process

From first assessment to implementation

1. Requirements

We clarify goals, current systems and the technical context.

2. Assessment

Relevant building, site, grid and consumption data are assessed.

3. Concept

The components and interfaces are combined in a coherent design.

4. Next phase

Scope, responsibilities and the route to implementation are agreed.

FAQ

Frequently asked questions

What determines the design?

The decisive factors are the site, demand, existing infrastructure, intended operation and planned extensions.

Can existing technology be included?

Often yes. Compatibility, interfaces and the condition of the existing system must be checked individually.

Is the solution expandable?

Expandability can be included in the initial design, provided the technical framework is defined accordingly.

When is a binding offer possible?

Once the relevant technical information, site conditions and desired scope have been clarified.

Assess a heat-pump concept

We review the technical conditions and plan heating as part of the overall energy system.

Heat Pump installation for your home!

Whether for private homes, offices, multi-unit residential buildings, or commercial properties, a modern heat pump allows you to heat and cool your building efficiently, comfortably, and in an eco-friendly manner. We provide tailored solutions and handle the professional installation of your heat pump—covering everything from the initial consultation and detailed planning to final commissioning.

 

Intelligent heating systems are particularly important for multi-unit residential buildings and larger properties; we develop scalable heat pump solutions suited to various building structures, ensuring optimal system design and future-proof expansion options.

 

By combining the system with a photovoltaic array, you can make the most of your self-generated solar power to operate your heat pump—efficiently, cost-effectively, and sustainably. You can also take advantage of attractive government subsidies available in 2026 for switching to renewable heating systems.

New Heating subsidies2026:

A modern heat pump at an energy-efficient single-family home in Germany, serving as an example of heating subsidies for 2026 and heat pump incentives in Mettmann.
The Federal Funding for Efficient Buildings (BEG) program, supported by KfW, promotes the switch to modern, climate-friendly heating systems. The goal is to significantly increase the use of renewable energy in existing buildings and achieve a lasting reduction in CO₂ emissions.

 

Many heating systems in Germany are still outdated and rely on fossil fuels. This is precisely where the new funding scheme comes in: owners of residential and commercial buildings receive financial support to switch to efficient heat pump systems.

 

Depending on individual circumstances, attractive grants covering up to 70% of eligible costs are available. This makes switching to a heat pump not only an environmentally friendly choice but also a particularly attractive economic proposition.

What is being funded?

  • Installation of new Heat Pumps as a heating system
  • Replacement of old oil or gas heating systems
  • Combination with renewable energies (e.g., Photovoltaics)
  • Complementary measures such as hydronic balancing and system adjustment

Prerequisites

  • Replacement of an existing heating system or new construction according to standard
  • Use of an eligible heat pump in accordance with KfW/BEG guidelines
  • Installation by a qualified specialist company
  • Submission of application prior to the start of work

Delivery head

  • up to 70%of the eligible costs (depending on the situation)
  • Basic funding for heating system replacement
  • Additional bonuses (e.g., for old heating systems or income)
  • Maximum funding amount depends on the building and the scope of the project.

Who can apply for the funding?

  • Private individuals as owners of residential buildings
  • Condominium Owners’ Associations (WEG)
  • Companies and commercial enterprises
  • Housing associations and Real estate companies
  • Municipalities and public institutions
