Germany’s thermondo Raises €50M Funding

With this funding, around 1,600 homeowners in Germany can install heat pumps on easy monthly instalments, avoiding heavy upfront costs.

The plan offers fixed 15-year payments at a 6% interest rate, starting below €300/month. With government subsidies (up to 70%), monthly payments can drop to under €100.

Customers can repay early at no extra charge and keep full ownership of the heat pump. Thermondo also handles everything—from consultation to service—making the switch simple and cost-effective.
