How the Subsidy Check 2026 Works (Short & Understandable)

With this Heat Pump Subsidy Check 2026, you get a reliable orientation in 2 minutes on how high your possible grant for heating replacement can be – including cost limits per dwelling unit and the most important bonus components. The calculator is deliberately "practical": You simply enter the gross total costs from the quote (heat pump, installation, dismantling/disposal of old system, necessary ancillary work) and check the boxes for the conditions that really apply to you. The result is not an approval, but a clear basis for decision-making for budget, quote comparison, and next steps.

How the result is created:
1) The calculator first determines the maximum eligible costs. This limit depends on the number of dwelling units in the building. If the new heating system does not serve all dwelling units (e.g., floor solution), the limit is distributed proportionally. If the actual costs exceed the limit, the excess is shown in the calculator but not "subsidized".
2) Then subsidy components are added: Basic subsidy plus possible bonuses (Climate Speed Bonus for early replacement of certain old systems, Income Bonus for owner-occupying households up to the income limit, Efficiency Bonus for certain heat pumps). The federal subsidy rate is capped – so you can immediately see if checking more boxes brings anything at all.
3) Optionally, you can add a regional/municipal additional subsidy as a percentage value. This is shown separately because cumulativeness varies by program.

What to enter sensibly:

• Use realistic total costs (gross). If you don't have a quote yet, start with an estimated value and update later.
• Check "Old System" honestly: Only certain heating systems or age limits count for the Speed Bonus.
• Choose the planned application period: A time window applies for some bonuses, which changes in later years.

Next steps after the check:
1) Save or print the result and use it as a basis for discussion.
2) Compare quotes not only by price: Pay attention to heat load design, hydraulics, hot water concept, noise, maintenance, warranties, and a clean commissioning protocol.
3) Collect subsidy documents early (proof of income, property/usage details, technical proofs). Often the rule applies: Application first, contract/commissioning only afterwards – otherwise you risk the claim.
4) If you are unsure, energy consulting is worthwhile: Correct design (flow temperatures/heating surfaces) often decides more about later costs than the mere device price.

Note: "Subsidy rate" is just the percentage number. Decisive are the eligible costs and the cap – that is exactly why this calculator shows both transparently.

Note on data status: Subsidy conditions can change due to budget situation or guideline updates. The calculator depicts the common components and makes the calculation logic comprehensible, but does not replace the current preliminary subsidy check. If you know the date of your application, you can select the period and immediately see how the bonus changes.
