High Temperature Heat Pump

A high temperature heat pump is a heating system that delivers temperatures above 100°C, significantly higher than conventional heat pumps which typically operate at 35-55°C. The technology uses compression cycles and natural refrigerants to upgrade low-grade heat sources for district heating networks and industrial facilities.

‍

At Solid Energy, our high temperature heat pumps reach up to 165°C, making them suitable for demanding heating applications.

High temperature heat pumps deliver reliable performance where conventional systems cannot. They work with multiple heat sources and maintain efficiency across demanding temperature ranges.

‍

The systems recover waste heat from various sources — typically 50–100°C — and elevate it to temperatures exceeding 100°C, transforming wasted energy into a valuable resource for heating networks.

‍

This is achieved using 100% natural refrigerants, delivering both environmental responsibility and strong operating economics.

‍

High temperature heat pumps work well in district heating systems requiring significant heating capacity — typically 60°C to 135°C. Our solutions integrate with existing infrastructure and give operators the flexibility to balance multiple heat sources, including renewables, geothermal energy, and industrial waste heat.

‍

For industrial facilities, the same technology supports waste heat recovery and ties into existing heating infrastructure with minimal disruption.

High-temperature heat pumps deliver up to four units of heat for each unit of energy and work with air, water, brine or waste heat. Our modular solutions are assembled according to specific temperature and capacity requirements. Integration is about matching the heat pump to system requirements and available heat sources — here we draw on a broad base of experience and support the operation with service and maintenance agreements of typically five years.

‍

The initial investment is higher than with standard boiler replacements, but the combination of energy savings and reduced emissions makes it an attractive choice for district heating companies planning their green transition.

At Solid Energy, we are aware of the importance of reliable operation and efficient maintenance of district heating and industrial pipelines. Our service and maintenance contracts run over five years and are designed to make the most of your investment.

Intelligent monitoring enables remote diagnosis and rapid response when service is needed. Combined with competitive investment and operating costs, our systems deliver great value throughout their lifetime.
