What Hamworthy Heating does
Hamworthy Heating Limited is a British commercial heating and hot water equipment manufacturer operating since 1914 and headquartered in Hull, United Kingdom. The company designs, manufactures, and supplies a portfolio of high-efficiency condensing gas boilers (wall hung and floor standing), commercial heat pumps using natural refrigerants, stainless steel and glass-lined water heaters and calorifiers, and supporting ancillaries including hydraulic separation and pressurisation equipment, sold under eight sub-brands (Tyneham, Stratton, Modumax, Purewell Variheat, Varmax, Dorchester, Powerstock, Halstock). Its products are specified into UK commercial buildings across education, healthcare, hospitality, offices, public sector, and historic/heritage segments.
The business sells primarily through an enterprise field-sales model, with UK-wide Area Sales Managers providing direct consultation, specification support, site surveys, and quote-based pricing, supplemented by a website-based quote and CPD-accredited training programmes delivered through partnerships with CIBSE, SoPHE, BESA, and ICOM. The company is a wholly-owned subsidiary of Groupe Atlantic, a European heating and hot water conglomerate, and operates solely within the United Kingdom market.
Revenue is generated principally through hardware sales of commercial heating capital equipment, with a recurring-revenue Commercial Service Division for service, maintenance, and repairs launched in November 2025. Recent strategic activity has been focused on positioning for the UK commercial decarbonisation transition, including MCS certification of the Tyneham 290HT air source heat pump, refresh of the Varmax mk2 boiler line, and expansion of the aftermarket service offering.
