Certificate counts are computed from the model's registered performance data using the current regulated equations. A lodged claim depends on the specific installation, household size, and the scheme rules in force at creation. Energy savings % is against the AS/NZS 4234:2021 reference electric storage water heater for that zone and load size, calculated from the model's registered performance data, or taken directly from the register where it publishes a savings figure. VEU registers this data at the small load (the step-down load for a medium-rated system) and ESS at the medium load, so the two schemes' figures differ for the same zone.
The Envirosun ES200M9 is an all-in-one heat pump water heater: a single cabinet with an R290 wrap-around coil heat exchanger around a 190 L tank (marketed as the 200 L class). The heat pump delivers 3.2 kW of average heating capacity at a rated power input of 0.78 kW, giving a declared COP of 4.16 at 20 degrees C / 15 degrees C ambient air heating water from 15 to 55 degrees C.
The unit operates in ambient temperatures from -7 to 45 degrees C and reaches up to 65 degrees C from the heat pump alone, with a 1.5 kW electric element available for boost heating up to 75 degrees C. Sound pressure is 42 dB(A) at 1 m. The tank has magnesium anode corrosion protection and an IPX4 waterproof rating.
This is the same physical unit sold under the Wulfe (WPW200M9) and Enviroheat (EH200M9) names from the same manufacturer group, Energie Group Australia. Enviroheat now has a matching register entry (EH200M9) on STC, VEU and ESS, so certificate values apply under either brand; Wulfe still has no matching register entry.
