Winterwarm

What Winterwarm does

Winterwarm Heating Solutions B.V. is a Dutch privately-held manufacturer of unit air heating, cooling, and LED lighting systems for industrial, agricultural, and commercial buildings, founded in 1936 and headquartered in Winterswijk, Netherlands, with a UK subsidiary (Winterwarm UK Ltd.) in Warrington. The company operates through the holding company WinEnergy B.V. and additional subsidiaries Winterwarm Agri UK Ltd. and Industrial Heating Service B.V. Its product portfolio spans condensing gas-fired heaters (HR series at ~106% efficiency), hybrid heat-pump/gas Qwikshift systems (QSE/QSG), LPHW unit heaters (WWH, JET), electric heaters (EH, DX-EH), direct gas agricultural heaters (DHX, DXC, DXE), air circulation/destratification units, radiant tubes, air curtains, and the WinterCooler — complemented by WinLed and Luminaid LED lighting brands. All products are developed, produced, and tested in-house, with manufacturing now augmented by a Prima Power Night Train FMS automated sheet-metal line commissioned in 2026.

Winterwarm monetizes primarily through quote-based hardware sales to enterprises and SMBs (industrial manufacturers, poultry/agricultural operators, food distributors, commercial venues) via regional field sales managers in the UK and a certified installer/service-partner network globally, supplemented by an online service-parts webshop and recurring annual servicing contracts (mandatory in the UK). Revenue is not publicly disclosed; the firm has no institutional funding, is family-controlled, and operates with 11–50 employees. The technology positioning is efficiency-led (up to 70% CO2 reduction, ~106% condensing efficiency, Modbus/BMS/Smart-Grid integration), and the go-to-market is relationship-driven, with technical consultation, Quickscan heat-load tools, and industry trade shows (VIV Europe, British Pig and Poultry Fair) supporting demand generation across three vertical segments: industrial (primary), agricultural (primary), and commercial (secondary).
