Company profile
About Siddons Solarstream
Siddons Solarstream Pty Ltd is the publisher identified on the surviving owner manual for its bolt-on air-to-water heat-pump systems. The publication addresses Australian installations through an Australia-only warranty and an Australian Consumer Law statement written specifically for local system owners throughout the country and its territories.

Its covered MAHRW010ZB range paired a split heat-pump module with stainless-steel, vitreous-enamel or separately supplied water storage. The MK4068 control schedule monitors six temperature points alongside water flow, refrigerant pressure protection, phase sequence and controller communications.

Evidence catalogue record
Data record for Siddons Solarstream
The evidence catalogue contains 21 exact Siddons Solarstream model records: 21 current rather than a single undifferentiated product entry. Siddons Solarstream register rows carry eligibility dates from 22 June 2006 to 31 December 2030, which supplies market-history context without claiming that every recorded unit remains available from retailers today. Captured Siddons Solarstream documents used by this project describe MK4068 bolt-on heat-pump controller display, and each source scope stays separate instead of becoming one generic brand-wide fault table. Those publications presently support 4 of 21 Siddons Solarstream model mappings across 1 public fault-code namespace; other records remain identification entries until equivalent controller evidence is found.

Siddons Solarstream owners can use Public Siddons bolt-on owner manual as the current public route preserved here for service questions or a warranty assessment based on the exact appliance. The official Siddons Solarstream warranty material documents Legacy Australian manual: 10 years for a stainless-steel tank with qualifying pure water, 5 years for a glass-enamel tank, 3 years for the bolt-on heat pump and parts, and 1 year labour, and this hub keeps those periods tied to the cited product scope instead of presenting a universal brand promise. This Siddons Solarstream context therefore joins a dated register record, exact manual scopes and a live support source; the separate owner guide focuses on identifying plates and reading controllers rather than repeating this profile. For Siddons Solarstream, the boundary between a listed model and an evidence-mapped controller is deliberate: registration establishes identity, while only the referenced publication establishes which fault meanings belong on a model page.
