What Viessmann UK does

Viessmann UK, operating as Viessmann Limited, is the United Kingdom subsidiary of Viessmann, a German-founded heating, climate, and renewable energy technology manufacturer established in 1917. Following Carrier Global Corporation's 2023 acquisition of Viessmann's climate solutions business, the UK entity now operates within Carrier's Viessmann Climate Solutions division, headquartered at Telford. The company manufactures and distributes a comprehensive product portfolio spanning gas condensing boilers (Vitodens family, 1.9–35 kW), air source and ground source heat pumps (Vitocal family, 2.1 kW to 240+ kW), commercial and industrial boilers (Vitocrossal, 87–1400 kW, and Vitomax), combined heat and power units (Vitobloc, 50–530 kW electrical), solar thermal collectors (Vitosol with patented ThermProtect switching absorber), photovoltaic systems (Vitovolt 300), unvented hot water cylinders (Vitocell, 100–600 L), mechanical ventilation with heat recovery (Vitovent/Vitoair), oil and electric boilers (Vitorondens, Vitotron), and digital connectivity via the ViCare app and Vitoconnect adaptor. The portfolio rests on proprietary technologies including the MatriX-Plus burner with Lambda Pro combustion controller, the Inox-Crossal stainless steel self-cleaning heat exchanger, ThermProtect switching absorber, and the NC-Box natural cooling module.

Viessmann UK sells exclusively through a two-tier channel: a network of Viessmann Academy-trained, BPEC- and CIPHE-accredited installers backed by merchant and distributor stockists, plus a direct field sales force of Regional Sales Managers and Business Development Managers covering Scotland and Northern and Southern England to support enterprise accounts including housebuilders, local authorities, housing associations, and energy partners. Revenue streams include hardware sales (boilers, heat pumps, solar, spare parts), chargeable technical pre-sales and MCS design packages (£600–£849+VAT), accredited installer training courses (£140–£180+VAT), and multi-year warranty extensions (7-year standard, upgradeable to 10 or 12 years). Customers span residential homeowners, certified installers, regional housebuilders, social housing providers, and commercial/industrial operators, with regulatory tailwinds from the UK Boiler Upgrade Scheme offering up to £7,500 per heat pump installation.
