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 Siddons Solarstream 417SMBD is a split-system heat pump water heater: an outdoor R417A heat pump unit connected by pre-charged refrigerant lines to a 417 L glass/enamel-lined storage tank, with the condenser coil wrapped around the outside of the tank rather than sitting inside it. The heat pump draws a maximum 1.38 kW electrical load and operates across the -5 to 45 degrees C ambient range, with a factory-default tank thermostat set point of 57 degrees C (adjustable 50 to 65 degrees C).
The 417SMBD is the largest tank in the range, sharing its heat pump platform, controller and tank design with the 165, 261 and 326 litre models, and with the R290-charged 417SMCD variant of the same tank size. No electric backup element is fitted or required.
Warranty is 5 years on the storage tank, 4 years on the compressor, 2 years on other heat pump parts, and 1 year on labour.
