Whether you are just starting out or have 10 years of field experience, the structured curriculum gives you a complete, organised picture of the whole system, from physics to service.

R290 vs R32: Which refrigerant is better for heat pumps? Compare GWP, operating pressures, and maximum flow temperatures to see why R290 is gaining popularity.

Oversizing a heat pump can reduce COP, cause frequent compressor cycling, and lower seasonal efficiency. Learn why proper sizing and modulation range matter.

Do TRVs (thermostatic radiator valves) increase energy consumption in heat pump retrofits? This article explores the “bad setback effect,” internal heat transfer between rooms, and how control strategy (weather compensation vs. stiff regulation) impacts COP and system efficiency.

Do you really need a buffer tank in heat pump systems? Learn the difference between open loop, volumizer, and hydraulic separation setups and when each is required.

Learn how ventilation heat loss affects heat pump sizing and energy costs. Discover why calculations may overestimate air change rates and how MVHR and blower door tests improve accuracy.
