High Temperature Heat Pumps solutions that deliver both high performance levels and flexibility in application, reflected in the Industrial & Commercial High Temperature Heat Pump ranges that Pure Thermal provides.
Application flexibility is key to delivering both the lowest operating costs and also the highest levels of carbon savings. Pure Thermal High Temperature Heat Pumps are available in single stage (Monobloc) or Two Stage system configuration to match an applications requirement.
Monobloc Pure Thermal Commercial High Temperature Heat Pump units with single a stage refrigeration system are able to deliver an 80°C output temperature down to a -5°C external temperature. This removes the need to specify a cascade or two stage (2 x heat pump) system for medium capacity applications.
For larger application the Pure Thermal PLUS SO System delivers a Two Stage High Temperature Heat Pump option to 3000kW+ with single system control & operation. With PLUS SO the control of the first stage High Temperature Heat Pump and the second stage water-to-water heat pump is completely self-contained to provide the next generation of large capacity Two Stage High Temperature Heat Pump systems.
Where waste heat is available a Pure Thermal Industrial High Temperature Heat Pump can operate with dual or multiple source configuration. This means that the unit will operate as a High Temperature Heat Pump but importantly also has the ability to operate with a second source to provide increased levels of efficiency. For example, an application may have a cooing requirement through the heating season, but varying in time and capacity, this means that a 14°C flow is available from the chilled water return at certain times. Therefore, if the external temperature is 7°C then the Pure Thermal Dual Source Heat Pump can operate using the 14°C cooling water return and not lower temperature air as its source heat which increases efficiency and hence uses less input electricity to operate.
Identifying the most appropriate system design is key to any project and to assist in this process Pure Thermal High Temperature Heat Pumps can be provided with a Heat Pump Ready Verification Service which identifies the most appropriate & available system options to deliver the highest level of efficiency. At this stage, the type of Heat Pump is secondary as the focus is on providing the best advice based on the opportunity that the application presents.
High temperature heat pumps are advanced heating systems designed to deliver output temperatures above 55°C, with the capability to reach a maximum flow temperature of 120°C. Unlike conventional heat pumps, which typically operate at lower temperatures, these systems provide a high-performance heating solution for applications requiring elevated thermal output, such as industrial processes, district heating, and commercial hot water production.

Higher output temperatures often negate the need to make changes to the emitter/distribution system that the Heat Pump is being installed into providing installation cost savings. Retrofit applications where Higher Temperatures are needed for only a proportion of the year are now viable via A High Temperature Retrofit Heat Pump system without the need for additional heat sources.
High Temperature Heat Pumps widen the scope for Heat Pump application and enable Carbon and Cost savings to be achieved across a wider range of projects and applications that would otherwise have utilised high carbon fossil fuels.
The typical barriers to the utilisation of heat pumps within an existing installation revolve around the heating system. Primarily the emitter refurbishment/replacement costs in order for the heating system to be able to operate at standard circa 45°C standard heat pump operating temperatures. In most cases, these refurbishment costs and the practical problems of modifying existing heating systems mean that 45°C or 55°C heat pump use is not possible.
The typical barriers to the utilisation of heat pumps within a new installation revolve around the hot water production. Hot Water production at 65°C is higher than standard heat pumps which are unable to provide this output. In most cases the additional installation costs and running costs of a fossil fuel system to provide the hot water requirements, make heat pumps a less attractive cost and carbon saving solution.
