Hydrocarbon Heat Pumps
Absolutely Chilled & Heating delivers advanced hydrocarbon heat pump systems by REFRA – engineered for maximum efficiency, future-ready compliance, and minimal environmental impact. Powered by natural refrigerants like R290 (propane) and R1270 (propylene), our systems are fully PFAS-free and support F-Gas phase-down targets.
Why Choose an ASHP or WSHP?
Efficient. Sustainable. Regulation-ready.
Air-to-water and water-to-water heat pumps from Refra offer an environmentally responsible alternative to traditional HVAC systems – delivering high-efficiency heating and cooling in a single reversible unit. Using natural refrigerants like R290 (propane) and R600a (isobutane), they align with F-Gas and PFAS regulations while offering ultra-low global warming potential (GWP ≤3).
Refra’s ASHPs and WSHPs are designed for commercial and industrial applications, incorporating full inverter technology to optimise seasonal efficiency, reduce energy use, and meet the evolving demands of decarbonisation. Whether used for space heating, comfort cooling, domestic hot water, or integration with low-temperature heating systems, they offer flexible, future-proof performance.

Hydrocarbon Air Source Heat Pumps
Reversible heat pumps provide efficient heating and cooling from a single unit – ideal for commercial and industrial applications with changing seasonal demands. Using natural refrigerants and full inverter technology, these systems offer a low-carbon, cost-effective alternative to traditional boiler or chiller combinations. With heating capacities up to 550 kW, flow temperatures of up to 70 °C, and advanced sound insulation, they’re suitable for everything from light commercial settings to large-scale facilities. For additional heat or redundancy, they can also be integrated with our water source heat pumps.
Flamma
Flamma
Flamma is a small-capacity, reversible air-to-water heat pump designed for commercial and industrial applications with lower heating and cooling demands. Operating with natural refrigerant R290 and full-inverter technology, it delivers between 20 kW and 50 kW of heating and 14 kW to 35 kW of cooling from a single compact unit.
Flamma units offer dual functionality for both heating and cooling, making them ideal for space-saving installations. Built with EC fans, scroll or reciprocating compressors, and finned tube or microchannel condensers, they provide high efficiency and low environmental impact.
The powder-coated galvanised steel frame is insulated with non-flammable 20 mm PU foam for sound and thermal control, with the option to upgrade to 30 mm rock wool for ultra-silent operation. Installation is simple thanks to Refra’s plug-and-play design philosophy.
