The Thermastore Heatwave 270 is an all-in-one heat pump water heater: a single outdoor cabinet integrates the R290 heat pump and 270 L storage tank. At the manual’s rated test point (20/15 degrees C ambient, 15 degrees C inlet, 55 degrees C outlet), the unit delivers 3.3 kW of heating capacity for 0.77 kW power input. It operates in ambient temperatures from -5 to 43 degrees C and holds a rated outlet water temperature of 60 degrees C.
The heat pump uses a rotary compressor with an R290 charge of 400 g, and a 1.0 kW electric element provides backup heating in Hybrid or Fast Heating mode. Sound rating is 49.5 dB(A). The all-in-one cabinet measures 640 mm diameter by 1950 mm tall.
Thermastore covers the tank for 6 years, the compressor for 5 years, and parts for 5 years, with 1 year on labour; warranty beyond three years requires a professional service. The Heatwave 270 is the single model registered under this brand for STC, VEU, and ESS.
