What Kesselheld does

Kesselheld is a Düsseldorf-headquartered German digital heating installation portal founded in 2015. The company operates a lead-generation and matching platform that connects homeowners and property owners across Germany with a vetted network of more than 400 partner heating installation technicians. Its product surface spans all major residential heating categories — heat pumps (Wärmepumpe), gas, oil, alternative systems (infrared, pellet, solar thermal, CHP, fuel cells), thermal storage, photovoltaic, solar, and advanced technologies such as ice storage and zeolite heating — alongside a subsidies advisory service for KfW and BAFA funding programs and a maintenance/comparison offering.

The platform monetizes primarily through referral and lead-generation fees paid by partner technicians for successfully matched customer leads. Kesselheld supports this commercial flow with a substantial content marketing operation: a comprehensive Ratgeber (expert guide) covering heating technology comparisons, cost calculators, subsidy explanations, and regulatory information such as the Heizungsgesetz. The company claims over 4.5 million visitors, driven by organic search and content-led top-of-funnel acquisition, with phone-based customer service (0800 111 0440) handling consultation and quote conversion. Equipment manufacturer partnerships with Vaillant, Viessmann, Buderus, Wolf Heiztechnik, Junkers (Bosch), and Brötje are featured on the portal; these appear to be co-marketing relationships rather than disclosed commercial integrations.

Operationally the business runs as a digital lead marketplace: free consumer-side consultation, nationwide matching to a curated partner installer base, and monetization on the supply side via lead referrals. No funding rounds, investor names, headcount, or financial disclosures are available in the source data, and there are no documented AI/ML, automation, or proprietary technology components beyond standard portal/web content infrastructure.

Direct peers

• Thermondo: Germany's largest dedicated heat-pump installer, owning end-to-end demand, installation, and subsidy handling; competes with Kesselheld by absorbing the customer match step rather than routing to independent partners.
• 1Komma5°: Vertically integrated German residential energy platform delivering heat pumps, solar, and EV charging; bypasses the referral / matchmaking layer entirely and competes for the same residential modernization customer.
• MyHammer: German online marketplace for tradesmen services including heating installers; competes with Kesselheld for matching homeowners with local HVAC professionals using a similar lead-generation model.
• Aroundhome: German home-services marketplace that connects homeowners with vetted craftsmen across categories including heating and bathroom renovation; closest direct competitor to Kesselheld, operating the same lead-gen / referral model for residential trades.
