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, medium household, calculated from the model's registered performance data.
The EverythingEco AHP25-320/N6G1BP is an integral R290 heat pump water heater: the compressor, fan and coil are built into the same cylindrical cabinet as the 320 L storage tank (640 mm diameter, 2210 mm tall, 122 kg net), with no separate outdoor unit or field refrigerant pipework. R290 is a flammable A3 refrigerant, so the manual requires outdoor installation only, with unobstructed airflow around the air inlet and outlet. Rated heating capacity is 2.5 kW at a power input of 0.455 kW, tested with inlet water from 14 to 55 degrees C and air at 19 degrees C DB / 15 degrees C WB, matching the smaller 270 L model in the range.
The heat pump operates from -10 to 43 degrees C ambient; outside that range the electrical backup element activates to meet demand (the manual does not state the element’s rated output). Outlet water temperature is adjustable from 35 to 65 degrees C, and a weekly legionella control cycle boosts the upper 90 percent of the tank to 61 degrees C, a function that cannot be overridden by software settings. Water connections are G3/4 inch, with a PTR valve set at 850 kPa.
This model is registered for STC creation under the exact model code AHP25-320/N6G1BP; it does not currently appear on the VEU or ESS registers.
