What Solvis does
Solvis GmbH is a Braunschweig-based, privately held German manufacturer of modular hybrid heating systems, founded in 1982 (with the 1988 date marking its pivot to solar thermal) and operating under CEO Gabriele Münzer and Markus-Oliver Kube. The company designs, produces, and sells 'Made in Germany' heating systems that combine solar thermal collectors, air-water heat pumps (using R290 and R454B refrigerants), pellet boilers, gas/oil condensing boilers, and PV-to-heat components under a single proprietary energy management controller (SolvisControl-3) with browser-based remote access via the SolvisPortal. The core technical differentiator is the patented Schichtenlader (stratifying loader) in buffer storage, which uses thermodynamic stratification to eliminate mixing losses in thermal storage. All manufacturing occurs at the company's Nullemissionsfabrik (Europe's first zero-emission heating system factory) in Braunschweig, with control technology R&D at the Eggolsheim site acquired via the 2020 Prozeda GmbH purchase.
The company operates a B2B2C go-to-market model exclusively through a certified Fachhandwerker (SHK trade) partner network recruited via solvis-partner.de, supported by the SOLVIS Akademie training program, DATANORM/GAEB data feeds, and KfW subsidy administration support. End customers (German single-family homeowners and select commercial accounts) interact with SOLVIS only via the website's Heizkonzept configurator, online info evenings, and trade partner referrals — pricing is not publicly disclosed and is set trade-by-trade with up to 70% government subsidy offset (KfW/BEG 2024). Revenue streams are predominantly one-time hardware sales (heat pumps, buffer storage, solar thermal collectors, pellets, PV components, fuel cells) supplemented by training services revenue from the Akademie.
The group comprises five legal entities (Solvis GmbH, Solvis Holding GmbH, Solvis Grundbesitz GmbH, Prozeda GmbH, and the controlling entity) across three locations, with ownership held by the management team (majority) alongside Berlin-based PE firm capiton AG and Austrian investor Andlinger & Company (minority). Revenue grew from 28M EUR (2019) to 44M+ EUR (2021), with 2022 core business revenue reportedly more than doubling year-over-year; headcount grew from 160 (2019) to over 350 (2023), positioning Solvis as a mid-market leader in the German renewable heating transition supported by tightening Gebäudeenergiegesetz regulation and KfW/BEG subsidies.
