MHG Heiztechnik

What MHG Heiztechnik does

MHG Heiztechnik GmbH is a German manufacturer of residential and commercial heating systems, headquartered in Buchholz in der Nordheide and operating as a wholly-owned subsidiary of US-based Rheem Manufacturing Company. Founded in 1927, the company designs, produces, and distributes a full portfolio of heating hardware under two product lines — MEISTERlinie (wholesale trade) and CARBONlinie (low-voltage radiant heating) — including gas and oil condensing boilers, air-to-water heat pumps, gas and oil burners (anchored by the proprietary Raketenbrenner® rocket burner), solar thermal collectors, hot water and buffer storage tanks, and c-flex carbon radiant heating film. The company was an early mover on hybrid heating concepts, introducing combined heat-pump-and-condensing solutions as early as 2009–2010, and has continued to expand its heat pump line with cascadeable systems (ecoWP 2Xe, 6–54 kW).

The company sells exclusively through a nationwide network of certified trade partners (SHK-Fachbetriebe / Fachpartner) in Germany, supported by wholesale building-materials distributors and a Fachpartner Portal that provides technical documentation, downloads, training, and warranty processing. Products are not sold directly to consumers; instead, an online 'Experten-Suche' (expert search) tool directs end customers to local certified installers. Revenue streams consist of hardware sales, spare parts and maintenance (with a 10-year post-production parts availability commitment), and recurring extended-warranty programs of up to 60 months that are conditional on annual maintenance and use of MHG-branded consumables and installers. Digital service layers (MHG Dashboard, MHG Mobil App) extend the relationship over the equipment lifecycle. Pricing is not publicly disclosed, but minimum order thresholds, free-house delivery above €50 net, and warranty labor rates of €42/hour plus €35 travel are documented in partner terms. Geographic scope is Germany-only, and the company holds no disclosed patents, funding rounds, or M&A activity in the available data.

Core offering

MHG Heiztechnik manufactures and distributes heating systems and components including gas and oil condensing boilers (Brennwertgeräte), heat pumps (including the ecoWP 2Xe cascade system), the proprietary Raketenbrenner® burner technology, solar thermal collectors, hot water storage tanks, and low-voltage carbon radiant heating films. Products are sold exclusively through a network of certified trade partners (Fachpartner/SHK-Fachbetriebe) in Germany, primarily serving residential and small commercial heating applications in new builds and retrofits.

Product overview

MHG Heiztechnik offers a comprehensive portfolio of heating solutions organized into two main product lines: MEISTERlinie (for wholesale distribution) and CARBONlinie (for low-voltage radiant heating). The core product portfolio includes gas and oil condensing units (ecoGAS Pro/ProX, ecoGAS Kompakt, ecoOEL Pro, ecoDUO), heat pumps (ecoWP 2Xe cascade system, ecoWP Xe, ecoWP Xm, ecoFutura), burners (Raketenbrenner rocket burners, gas and oil burners), solar thermal systems, and storage solutions. The company pioneered hybrid heating technology combining heat pumps with condensing boilers as early as 2009-2010. CARBONlinie features the c-flex carbon radiant heating film system using safe low-voltage technology for floor, wall, and ceiling heating in new construction and renovation projects. Additionally, the company offers digital tools including the MHG Dashboard and MHG Mobil App for system monitoring. MHG operates as part of the Rheem Group and has been setting standards for clean and affordable heating solutions since 1927, with products manufactured in Germany.
