Biotherm Heat

What Biotherm Heat does

Biotherm Heat AB is a Västerås, Sweden-based private limited company that supplies automatic bioenergy heating systems to industrial, commercial, agricultural and municipal customers across Scandinavia. Founded in 1976 by Björn Jansson and currently owned by his sons Mikael (CEO) and Magnus (Product & Marketing Manager) Jansson, the company operates as the Scandinavia general agent for the premium PelleTech heating-system brand (Multiauto 20–200 kW wood-chip/pellet boilers, IDRO 200 kW–1.15 MW industrial boilers, and AERO 60 kW–2 MW hot-air boilers) and complements that line with its own Biotherm burners, prefabricated heating centrals (PHC, Biobox ALL INclusive, mobile heat centres up to 1 MW), fuel-storage systems (S.M.S, Skrapförråd, S-serie, PelleTech spring and scraping stores up to 500 m³), BTA accumulation tanks up to 10,000 L, and a service network.

The technical core of the offering is built around moving step-grate combustion, water-cooled combustion chambers with ceramic linings rated to 1,600 °C, lambda oxygen-based combustion control, cell-lock backfire prevention, and an automatic ash-removal chain — features that allow the systems to burn unusually wet and low-grade fuels, including wood chips up to 61% moisture, horse manure, and slaughterhouse waste. The proprietary Hästgödselbrännare (horse-manure burner, 250–1000 kW), now in its seventh generation, is the product of a 28-year (since 1996) R&D collaboration with Luleå University of Technology.

Biotherm monetizes through outright hardware sales (system price points from ~100,000 SEK up to >1,000,000 SEK for fully installed industrial plants), a B2B-only leasing option on bioboilers, rental of mobile heat centres, recurring service and maintenance contracts through a nationwide service network, and complete project delivery covering 3D planning, installation, commissioning, and on-site training. GTM is sales-led, with active participation in Swedish forestry, agricultural and construction trade shows (Skogsnolia, Skogsmaskindagarna, Brunnby Lantbrukardagar, Mittia) and direct quote-based engagement through phone, email, and the company website.
