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 Thermann 300THC25P is the plug-in version of Thermann’s 300 L integral heat pump water heater: the same 287 L tank and R290 (propane) heat pump cabinet as the 300THC25, but wired for a standard 10 A GPO rather than a hardwired connection. Rated power input is 2.0 kW at up to 10 A, with a 290 g R290 refrigerant charge, and a 1.2 kW electric element for boost mode. Hot water is delivered at up to 60 degrees C.
Cabinet dimensions (2005 mm tall, 620 mm diameter) and net weight (125 kg) match the hardwired 300THC25. Tank warranty is 7 years (3 years labour), heat pump components 3 years, other components 1 year, for single-family dwelling installations (shorter terms apply for other applications).
The -H suffix model on the register is identical except for a pre-fitted hard-water anode.
