High Temperature Air Source Heat Pump
Industrial processes and district heating systems often require more than a standard heat pump can deliver.
Solid Energy's industrial heat pumps are built for exactly these applications, combining flow temperatures up to 165°C, 100% natural refrigerants and modular configurations that integrate with existing installations.

Flow temperatures up to 165°C
The high temperature air to water heat pump from Solid Energy delivers flow temperatures up to 165°C, putting it in a different category from most heat pump solutions on the market.
This makes it the right choice for industrial processes and older district heating networks built around high flow temperatures.
Where high temperature heat pumps are used
High temperature air source heat pumps address a concrete challenge in sectors where processes depend on high and stable flow temperatures.
Industry and production
Food production, pharmaceuticals and the textile industry all depend on stable, high-temperature heat as part of daily operations.
A high temperature air to water heat pump connects directly to existing installations, delivering the required temperatures without rebuilding surrounding infrastructure.
The transition to electrically driven heat production becomes both technically straightforward and economically sound.
District heating
Older district heating networks are often designed for high flow temperatures, which rules out many standard heat pump solutions.
A high temperature air source heat pump closes that gap, allowing plants to electrify heat production on existing terms without replacing distribution infrastructure.
Power-to-X and process heat
In Power-to-X plants, surplus process heat can be fed directly into district heating via high temperature air source heat pumps, creating value at multiple points in the energy system.
It is a practical example of how the solution supports a broader transition to renewable energy.
Consistent efficiency at high temperatures
High flow temperatures normally put pressure on heat pump efficiency. Solid Energy's solutions maintain strong performance regardless, drawing on three core elements:
- Variable speed compressors that continuously adapt to the current heat demand.
- Intelligent defrost cycles that ensure reliable operation, even when outdoor temperatures drop significantly.
- Optimised refrigerant circuits based on 100% natural HydroCarbon refrigerants.
The combination delivers stable, year-round performance with an operating economy that outperforms both gas boilers and electric resistance heating.
Intelligent monitoring
Real-time remote access gives operators full visibility of performance at all times, making it possible to identify and address any deviation from expected output quickly.
This keeps unplanned downtime to a minimum and ensures the installation consistently performs as intended.

Modular solutions from 200 kW to 4,800 kW
Solid Energy's high temperature air source heat pumps are modular, with each solution tailored to the specific application and dimensioned to current heat demand. As requirements grow, capacity can be scaled accordingly.
Where needed, the heat pumps can also be integrated with existing boilers to handle peak load, ensuring efficient daily operation and full supply security when demand is at its highest.
More than 150 units delivered since 2018
Solid Energy has delivered more than 150 HC heat pump units to district heating plants and industrial facilities across Europe. All solutions are designed and produced in Denmark, and service and maintenance agreements typically run for five years, ensuring stable operation throughout the lifetime of the installation.
From the first conversation to commissioning, we provide guidance on the solution that fits your project, your temperatures and your capacity requirements.
