How we analyzed the searches
The basis is 11,646 search terms from the Google Ads Keyword Planner via DataForSEO, for Germany, October 2025 to September 2026. The searches are monthly averages of these twelve months; the tailwind compares them with the twelve months before. The bids are Google Ads' upper bid estimates for the top of the page.

- Searches unrelated to home heating are excluded. These include 213 terms on camping and motorhome heaters, fan heaters, heating oil, jobs and apprenticeships.

AI Overviews: manufacturers and energy suppliers are cited
We searched Google for 20 typical questions, for example "was kostet eine wärmepumpe mit einbau" (what does a heat pump cost including installation), "wärmepumpe oder gasheizung" (heat pump or gas heating) or "wie laut ist eine wärmepumpe" (how loud is a heat pump) (queried on October 19, 2026). For 18 questions, an AI Overview appears above the search results; only "wärmepumpe mit heizkörpern" (heat pump with radiators) and "wie finde ich einen guten heizungsbauer" (how do I find a good heating installer) have none.
Together, the AI Overviews cite 32 different websites in 54 mentions:
- Manufacturers: Bosch (5), Buderus (4), Viessmann (3), Stiebel Eltron, Wolf and ÖkoFEN, 15 mentions in total.
- Energy suppliers: Vattenfall (3), EnBW, EWE, MVV, GASAG, Green Planet Energy and energis, 9 mentions in total.
- Installation providers and advice sites: including thermondo (4), heizung.de (3), ADAC (3), Finanztip and Enter.
None of the 32 websites can be recognized by name as an individual local heating installation business. Only 14 of the 54 mentions come from websites that also appear among the top five regular search results.
How we build Google Ads for heating installers
- Separate campaigns per intent. Quotes and installation, funding, costs and the search for a business each get their own campaigns, their own budget and their own goals.
- Catchment area per location. We define the radius in which you install and connect the ads with address, call and Google Maps.
- Value of a job as the goal. We store the job value in the account and match inquiries with your CRM so that bids are steered toward jobs.
- Factor in photovoltaics. If you also install solar systems, the combination searches get their own campaign.
- Budget by season. More from October to February, less from May to August.
We exclude these searches
- Infrared heaters, if you don't install them: 209,943 searches per month at a €1.07 median
- Camping, RV and tent heaters
- Spare parts, heating elements and fan heaters
- “wärmepumpe selber einbauen” (install a heat pump yourself): 3,325 searches, +39%
Conclusion: funding, quotes and local relevance
The heat pump accounts for half of the demand and is growing, while gas and oil are declining. Searches for funding are growing the fastest; quote searches and combination searches with photovoltaics have the highest bids. Searches for a heating installer nearby are small but growing with local relevance. Google's AI Overviews currently feature manufacturers and energy suppliers, not local businesses.
