What Varmebaronen does

Värmebaronen AB is a family-owned Swedish manufacturer of heating and hot-water systems, headquartered in Österslöv, Kristianstad, and tracing its origins to the 1970s under founder Berth Nilsson. The company is currently led by CEO Christopher Nilsson and operates sub-brands Aqualux, Pellmax, and Viking Bio. Its core products include the EP G2 electric boiler series (31-1500 kW), Pellmax pellet boilers, Viking Bio pellet burners with automatic ash removal, wood-fired boilers, solar thermal collectors, and Aqualux accumulator tanks with proprietary stratification technology claimed to retain thermal separation 25x better than conventional tanks. The portfolio also includes a patented de-icing system and Modbus/BACnet-compatible smart controls, with the EP G2 offering Direct Power Control functionality that enables participation in grid-services markets.

The company sells residential and small-commercial products through an authorized installer network in Sweden, while industrial and enterprise customers are served via regional sales representatives. International markets are reached through export and distribution partnerships across the Nordics, Western Europe (France, Netherlands, Denmark, UK), Central Europe (Poland), and South America (Chile). Customers span residential villa owners, commercial property operators, and specialized industrial and institutional users including the Swedish Navy (HMS Visby), the European Southern Observatory (ESO), Royal FloraHolland, KLF, Lalandia, Imerys, Bäckaskog Slott, Tågdepå Käråkra, and district-heating operators in France and the UK. Revenue is generated primarily through hardware sales of heating equipment and, increasingly, an aftermarket spare-parts channel via the digital Reservdelskatalogen. The business model combines unit-priced product sales for the residential segment with higher-value project-based sales for industrial and institutional deployments, including MW-scale district-heating backup installations.

The company has operated for over 50 years and has been recognized with Dagens Industris Gasellpris award for growth and profitability. Active hiring of Electrician and Constructor roles in 2026 signals ongoing operational scaling.
