A lodged claim depends on the specific installation, household size, and the scheme rules in force at creation.

The Siddons Solarstream 264SSBD is a split-system heat pump water heater: an outdoor heat pump unit connected by refrigerant lines to a 264 L storage tank. The heat pump uses R417A refrigerant, draws 1.38 kW power input, and rates a recovery capacity of 100 L/hr at 20 degrees C. Sound level is 53 dBA, and the outdoor unit measures approximately 795 x 255 x 540 mm and weighs 39 kg.
The tank stands 1620 mm high with a 580 mm diameter and weighs 62 kg dry, rated to 500 kPa inlet water pressure. The 264SSCD register code is treated as a colour or revision variant of the same physical 264L tank/heat pump combination.
Siddons Solarstream ceased operations after 2016; this entry is sourced from the archived installation manual, not an active manufacturer site. COP, warranty terms, and certified standards were not available in the accessible manual pages.
