Energy-efficient heat pumps
At Kramer Installation A/S, we assist private individuals, housing associations, and businesses with energy-efficient heat pump solutions for heating and domestic hot water. We assess the building and the overall heating system before recommending a solution. The goal is stable comfort, efficient operation, and an investment that matches the actual need.

The right heat pump for the building
A heat pump must be correctly sized and coordinated with radiators, underfloor heating, hot water tanks, and the building's heating requirements. We assess existing installations, temperature requirements, and consumption patterns. Based on this, we advise whether a heat pump is the right solution and how the system should be designed.
- Air-to-water heat pumps for heating and domestic hot water
- Heat pump solutions for radiators and underfloor heating
- Adaptation of pipes, pumps, valves and tanks
- Integration with existing heating systems
- Control, balancing and functional testing
- Service, troubleshooting and ongoing optimization

Is the building ready for a heat pump?
Before the installation, we review whether the existing radiators or underfloor heating circuits can deliver the desired comfort at the heat pump's operating temperatures. If necessary, we propose improvements such as new radiators, better regulation, or optimization of the piping. This provides better conditions for efficient operation and reduces the risk of disappointment after installation.
Lower energy consumption and stable comfort
A correctly dimensioned and balanced heat pump can utilize energy efficiently and deliver a stable temperature throughout the year. The system's performance depends, among other things, on the building's insulation, heat distribution, and required supply temperature. Therefore, we work with the entire installation and not just the heat pump itself.
