- Here's an example: For a four-person household, costs of approximately €4,000 to €8,000 can be expected if only hot water is to be prepared. For a system with additional heating support, the costs are approximately €9,500 to €12,500. An additional cost factor is the domestic hot water storage tank. The costs are calculated based on the size of the tank. It is essential to apply for KfW funding, as the government can cover up to 50% of the investment costs. We can help you apply for these funding applications early, as approval is usually required before construction begins.
