Built for Real-World Performance
The iHEAT 18.5 kW R290 heat pump, installed and delivering 75% energy savings from day one. Compact, whisper-quiet, and engineered for tropical to temperate climates.
Key Specifications at a Glance
Two refrigerant platforms covering every commercial and industrial heating need.
75% of Your Heat Comes From the Air — Free
Your aircon takes heat out of a room and dumps it outside. An iHEAT does the same thing backwards — it takes heat from the outside air and puts it into your water. You pay for a quarter of the energy. The air gives you the rest.
25% Electrical Input
Only a quarter of the energy comes from the grid, powering high-efficiency compressors that move heat.
75% Reclaimed Energy
Three-quarters of the energy is harvested for free from ambient air, waste heat, water, or ground sources.
100% Useful Heat
The result: 100% of required thermal energy, delivered with a 75% reduction in primary energy consumption.
Natural Refrigerant Technology
iHEAT runs on CO₂ (R744) and R290 (propane) — natural gases, non-toxic and PFAS-free. Hot water up to 130 °C, and still legal as synthetic refrigerants phase out worldwide. Full engineering detail below.
CO₂ (R744) Systems
- Transcritical ThermodynamicsSupercritical heat rejection for hot water up to 130 °C and process cooling down to -40 °C.
- Ejector TechnologyRecovers expansion energy for high efficiency even at return temperatures up to 50 °C — ideal for retrofits.
- GWP of 1Zero ozone depletion, non-flammable, non-toxic. The ultimate environmental choice.
R290 (Propane) Systems
- Ultra-Low GWP of 3.3Over 700x lower than legacy HFCs. PFAS-free for long-term regulatory compliance.
- A+++ EfficiencyHot water up to 75 °C with industry-leading COPs, cutting energy costs dramatically.
- Advanced SafetyPressure relief, leak sensors, flame-proof electricals. IEC 60335-2-40 compliant.

What is the COP of iHEAT heat pumps?
iHEAT R290 heat pumps achieve COP 4.0-4.5, meaning you get 4-4.5 kWh of heat for every 1 kWh of electricity. CO2 models achieve COP 3.5-4.2 at higher temperatures up to 130 C.
What temperatures can iHEAT produce?
R290 models deliver hot water up to 75 C. CO2 transcritical models can reach up to 130 C, suitable for industrial process heating, sterilisation, and high-temperature sanitisation.
Are iHEAT systems MCS certified?
Yes, iHEAT systems are MCS (Microgeneration Certification Scheme) certified, making them eligible for UK government incentives including the Boiler Upgrade Scheme.
