What the site does

The site works out the grant for replacing a heating system under the federal efficient buildings funding guideline, running costs from official energy prices and degree days, and CO₂ costs under the Fuel Emissions Trading Act. It is not a service of the promotional bank, BAFA or any authority, not energy advice, not legal or tax advice, and it does not refer installers. Only the bank decides on your application. Methods: how we calculate.

Liability

Values are checked after every change to the guideline, the law and the official prices and are tested automatically before each release; we cannot guarantee that they are free of errors. Linked third-party sites are the responsibility of their operators. Please report errors via the contact page.

Embedding

The grant calculator and the running cost calculator may be embedded free of charge by iframe as long as the source link stays visible: embed a calculator.
