What KWB does

KWB Energiesysteme GmbH is an Austrian privately held energy systems supplier founded in 1994 and headquartered in St. Margarethen/Raab, Austria, with 101-250 employees. The company designs, manufactures, and distributes wood-fired and electrified heating systems — pellet boilers (Easyfire 1/2/3, Pelletfire Plus, Powerfire), wood chip systems (Multifire 2, Powerfire), log wood heaters (Classicfire 1/2), combination boilers (Combifire), and air-to-water heat pumps (EasyAir Plus, EmpaAir Hydro Split R290) — alongside an integrated system solutions stack comprising thermal and DHW storage (EmpaTherm, EmpaEco, EmpaCompact, EmpaWell, EmpaFresh), photovoltaic and battery storage, solar thermal, power-to-heat, and pellet/wood chip conveying equipment.

The technical backbone is Clee, KWB's proprietary energy management platform that coordinates heating, PV, battery, and storage components with weather-based forecasting across up to 2,000 square meters of managed living space, with the ComfortOnline app providing remote control. The company claims a 15-year minimum spare parts guarantee and positions its offering as a complete, future-proof, expandable renewable heating stack.

KWB operates an indirect go-to-market model through a certified partner/dealer network across at least 23 countries (Austria, Germany, France, Italy, Belgium, Denmark, Spain, Hungary, Ireland, Japan, Luxembourg, Morocco, Netherlands, New Zealand, Norway, Poland, Romania, Switzerland, Slovenia, Finland, United Kingdom, Canada, Chile), with a postcode-based lookup routing customers to local installers. Revenue is generated from hardware sales of boilers and heat pumps, complementary system modules, and recurring service and maintenance through the partner network. The company has served over 140,000 cumulative customers with 10,000+ installations of its bestseller products, and actively co-markets the Austrian Bundesförderung federal subsidy (up to EUR 8,500) to accelerate demand.
