There were nine models in the “Solar” range of domestic boilers, which were designed for hot water supply and small heating installations. Uniquely for small domestic appliances they had a corrugated firebox manufactured from “steelite” metal. These boilers were manufactured by Lumbys Limited, of Greetland Boiler Works, Halifax.
The boilers were available with various options, including boiler only; boiler only, with rustless fire-pot; baseplate, nickel plated top; nickel plated door; mica door; shaking gate (standard on model numbers 1, 1x, 2 and 2x); stoking tools. Model Numbers 1 to 6 could be fitted with a polished pan top, as on model numbers 0x, 1x and 2x, at no extra cost.
