R290 Heat Pumps: Safe Innovation, Not a Hidden Hazard

14 Jul 2026Heat Pumps

Dr. Halil İbrahim DağBoard Member / Technical Coordinator

R290 heat pumps run on propane, a natural refrigerant with near-zero global warming potential and excellent efficiency. The trade-off is A3 flammability — managed through charge limits, leak detection, sealed components and certified installation. With EU F-Gas rules squeezing out high-GWP refrigerants, R290 is a safe, forward-compatible choice when installed and maintained professionally.

Advantages of EVI Compressors in Heat Pump Systems

Dr. Halil İbrahim DağBoard Member / Technical Coordinator

Enhanced Vapor Injection (EVI) compressors inject extra refrigerant vapor mid-compression through an economizer circuit, keeping heat pumps efficient in deep subzero conditions. The result: up to 30% more heating capacity, higher COP, stable operation down to -20°C (some models -30°C) and lower operating costs — making EVI a key technology for cold-climate heat pump deployment, supported by EU and national incentive programs.
