Lochinvar

What Lochinvar does

Lochinvar Ltd is a UK-based, privately-held manufacturer founded in 1976 that designs, produces, and distributes high-efficiency commercial heating and hot-water equipment. The company serves commercial, public-sector, industrial, healthcare, education, retail and hospitality building projects across England, Scotland, Wales and Northern Ireland, supplying consulting engineers, M&E contractors, specifiers and end-user clients through a direct field-sales model organised around UK regional Area Sales Managers and a Banbury-based internal sales, technical support and service team.

The product portfolio is built around four interlocking technology stacks: (i) gas-fired condensing boilers and water heaters (CPM, EFB, Herald, Herald XL, TTB, EcoCharger, EcoForce, EcoKnight XL, EcoSword, EcoShield, EcoSable, TTW, Charger Low NOx) with seasonal efficiencies of up to 96–98.2% and ultra-low NOx output qualifying for maximum BREEAM credits; (ii) air-source and water-source heat pumps using R290 and other refrigerants (Amicus High Temperature, Low Temperature, Altus R290 up to 112 kW, Boost up to 496 kW, and the AquaStore heat-pump water heater); (iii) solar thermal collectors integrated via the proprietary HSV Thermal Store, which mitigates Legionella risk without pasteurisation; and (iv) the Imperium system controller and Con-X-us app, which provide smart switching between multiple heat sources and remote boiler monitoring.

Lochinvar monetises primarily through direct hardware sales out of the UK's largest commercial water-heater stock, supported by 2-working-day mainland delivery and a 5%-tier price increase observed in 2022 reflecting input-cost pass-through. Secondary revenue streams include spare-parts sales with next-day delivery, on-site commissioning, and routine maintenance/repair carried out by employed service technicians. Customer-acquisition and specification influence are driven by CIBSE-accredited CPD seminars, a national programme of trade-event sponsorships, technical whitepapers targeted at decarbonising hospitals and university estates, and dedicated Key Account Management for large public-sector estate retrofits (NHS, universities, local authorities).
