The Pure Thermal R290 propane heat pumps are a range of hydrocarbon heat pumps delivering the highest levels of sustainability using the non-F-Gas natural refrigerant and providing a future proofed heat pump solution for commercial and industrial applications.
Because R290 propane heat pumps use natural refrigerants, this heat pump range is ideally suited to situations where low environmental impact is a priority, or areas where legislation restricts fossil fuel use. Where sustainability standards must be achieved to meet client or planning restrictions or regulations, the Pure Thermal R290 propane heat pump range provides a highly efficient, practical, and cost-effective HVAC solution, whilst future proofing the installation completely by removing the application completely from F Gas regulation and reporting requirements.
Alongside the significant environmental benefits, R290 propane heat pump units provide a practical and efficient alternative to standard HFC heat pumps.
The R290 in R290 propane heat pumps refers to the type of refrigerant used in this range of heat pumps. It is a refrigerant grade form of the common fuel gas propane which is used as an alternative hydrocarbon refrigerant to R404A and R407. R290 is now typically used in new refrigeration and air conditioning systems. R290 is a hydrocarbon refrigerant and is an efficient refrigerant that has a low Global Warming Potential (GWP).
Here at Pure Thermal, our hydrocarbon heat pumps use the natural refrigerant R290 which has a Low GWP (Global Warming Potential) of just 3 (see the graph below which shows the GWP figures for various other well-used commercial refrigerants) whilst also providing a practical, flexible, and cost-effective refrigerant option with reduced environmental impact. R290 has many refrigerant applications including commercial air conditioning, commercial refrigeration, domestic air conditioning, industrial refrigeration, and industrial air conditioning.
R290 is one of, if not the most, practical natural hydrocarbon refrigerant to use within a modern heat pump, delivering an operating temperature up to 70°C whilst being simple to apply, and with no minimum return temperature restrictions (which can be the situation with CO2 natural refrigerant heat pumps).
In recent years, manufacturers and system developers have looked to identify suitable alternative organic refrigerants following the increased focus on the potential environmental implications of conventional refrigerants such as CFCs and HFCs and the increased legislation relating to the manufacture, distribution, and use of environmentally harmful refrigerants. This has led to the use of naturally occurring hydrocarbons for various heat pump applications such as R290 that provide an effective commercial solution with lower GWP. This new generation of environmentally friendly heat pumps are referred to as hydrocarbon heat pumps, propane heat pumps or more specifically R290 propane heat pumps.
The Pure Thermal R290 air source heat pump is designed to provide high-performance, sustainable heating and cooling solutions across a range of applications. Using R290 (propane) as a natural refrigerant, these systems offer low-carbon operation without reliance on F-Gas refrigerants, ensuring compliance with environmental regulations and sustainability targets. These heat pumps are available in multiple configurations to suit various heating and cooling demands. Heating-only units can achieve output temperatures of up to 70°C, making them suitable for applications requiring consistent high-temperature heating. For more flexible performance, reversible units provide both heating and cooling, adapting to seasonal requirements and maximising energy efficiency.
For businesses requiring simultaneous heating and cooling, 4-pipe heat pump configurations allow for multi-functional energy management, delivering 80°C heating, cooling, and domestic hot water production within a single system. This level of operational flexibility makes the R290 air source heat pump an ideal solution for commercial buildings, district heating systems, and industrial applications where efficient energy use and carbon reduction are priorities.
With the ability to support BREEAM and TM65 sustainability standards, these heat pumps contribute to zero or low-carbon projects, aligning with modern regulatory and planning requirements. Their ability to provide non-F-Gas heating and cooling solutions ensures that businesses can future-proof their HVAC systems, reducing long-term environmental impact while maintaining high-performance operation.
Every project begins with a detailed system assessment, where Pure Thermal’s technical team evaluates site conditions, energy demands, and application requirements. By analysing these factors, they develop an optimised system configuration, ensuring that the selected R290 propane heat pump system provides maximum efficiency, minimal energy consumption, and a seamless integration into existing infrastructure.
The system design phase considers factors such as heat load requirements, available energy sources, and sustainability objectives, ensuring that businesses receive a tailored solution that maximises operational performance while reducing reliance on fossil fuels. By incorporating air, water, or ground source configurations, the design process ensures that each system operates with optimal thermal efficiency and long-term reliability.
