Growing Demand for High-Temperature Heat Pumps in Commercial and Industrial Retrofit Projects

Dethermina Heat Pump

Pure Thermal is seeing increased demand for single-stage monobloc heat pumps that can provide high-temperature heating within existing commercial and industrial systems.

Many decarbonisation projects need to reduce carbon emissions without requiring major changes to existing emitters, pipework or plant infrastructure. A heat pump that can produce flow temperatures of up to 80°C can help meet this requirement.

These systems can match the temperature demands of existing heating and hot water distribution networks, including during periods of peak demand. This allows building operators to introduce low-carbon heating technology while limiting the need for costly changes across the wider system.

Increased Interest in the Dethermina A-Therm80 Range

This demand is driving strong interest in the Dethermina high-temperature A-Therm80 R290 heat pump range, available in the UK through Pure Thermal.

The range has been developed with retrofit projects in mind and can support a wide range of commercial and industrial heating applications.

Key features include:

  • Flow temperatures of up to 80°C
  • Operation at external temperatures as low as -20°C
  • R290 natural refrigerant
  • Delta T capability between 5°C and 20°C
  • Nominal capacities ranging between 30kW and 300kW
  • Single-stage monobloc configuration
  • Four-pipe simultaneous heating and cooling options
  • Retrofit-focused system design

The single-stage configuration can remove the need for multi-unit cascade arrangements in suitable applications. This can reduce system complexity and support a more direct approach to replacing or supplementing an existing heating plant.

Supporting Existing Heating Infrastructure

One of the main barriers to heat pump adoption in older commercial and industrial buildings is the temperature requirement of the existing distribution system.

Many buildings were designed around boilers that supply higher flow temperatures. Replacing these systems with a standard low-temperature heat pump may require changes to radiators, air handling equipment, pipework and other heat emitters.

The Dethermina A-Therm80 range can produce temperatures of up to 80°C when required, helping it work with existing infrastructure in suitable retrofit applications.

This gives project teams greater flexibility when planning decarbonisation work, particularly where replacing the full heating system would be costly or disruptive.

Four-Pipe Heating and Cooling

The Dethermina A-Combo80 range also offers four-pipe simultaneous heating and cooling.

This can suit buildings that require heat and cooling at the same time, including manufacturing facilities, healthcare settings, hotels, leisure facilities and larger commercial properties.

Recovered energy can be transferred between heating and cooling loads, supporting greater system efficiency and reducing wasted energy.

A Practical Route to Lower-Carbon Heating

The growing interest in high-temperature heat pumps reflects a clear market need. Businesses want to reduce emissions, but they also need systems that can meet existing temperature and performance requirements.

The Dethermina A-Therm80 and A-Combo80 ranges provide a practical option for commercial and industrial retrofit projects where high flow temperatures remain necessary.
