Heizma competitors and assessment
Company assessmentDirect peers
- Zolar: German online installer marketplace and integrator for residential PV, storage, heat pumps and wallboxes with financing — comparable as a DACH digital-acquisition + installer-network model competing for the same homeowner funnel as Heizma.
- Thermondo: Berlin-based heat-pump specialist with a regional Meisterbetrieb-style installation model and digital sales journey — directly comparable to Heizma's heat-pump-led value proposition and four-step consultative customer journey.
- 1Komma5°: German climate-tech integrator offering solar, heat pumps, EV charging, storage and a 'Heartbeat' AI energy-management platform under one brand — directly comparable to Heizma's integrated-meisterbetrieb + AI energy-manager proposition.
- Soly: Former Dutch residential solar + storage integrator that filed insolvency in late 2025; several hundred Austrian PV customers and ongoing projects were absorbed by Heizma in January 2026 — historically a direct peer competing for the same integrated residential energy proposition.
- Enpal: Germany's leading integrated residential solar + heat pump + EV charger + storage provider with leasing/financing and proprietary energy-management software — the closest German analogue to Heizma's 5-in-1 Komplettpaket + Optima + €0-down financing model.
Broad incumbents
- Vaillant: European heat-pump and heating-systems manufacturer with deep Austrian installer footprint and a flood-relief partner of Heizma — comparable broad incumbent competing for the same heat-pump replacement demand.
- Viessmann: One of Heizma's flagship heat-pump suppliers (Viessmann Vitocal 250-A is on the Optima compatibility list) and a global broad incumbent in heating, heat pumps and integrated energy systems — comparable as an incumbent player in the same installation funnel Heizma competes in.
- Bosch Thermotechnik (Bosch Home Comfort): Manufacturer of the Bosch Compress heat-pump series installed by Heizma (e.g., family Maier project, March 2025); a broad incumbent heating-systems player whose products Heizma both specifies and competes against in the Austrian replacement market.
- Solarwatt: Established German manufacturer and integrator of PV modules, battery storage and energy management (MyReserve) — a broader incumbent operating in the same residential PV + storage + EMS category as Heizma's offerings.
- Daikin: Global HVAC and heat-pump leader with strong DACH/Austria presence — broad incumbent whose air-source and ground-source heat pumps compete for the same residential heating-system replacement demand Heizma addresses.
