Circulation pump exchange programme B2C
Description of the EES
This EES exchanges old inefficient circulation pumps with a high efficient circulation pump that saves up to 80% of electricity. It is a standard product with the same payment for all customers. Remuneration for the EES provider via the steady electricity bill is within four years. The idea of the EES is that a nonvisible part of the heating system gets more attention. The electricity bill shows an obvious reduction in consumption after the second year.
The marketing efforts have been very successful. Because of the unique selling position with this EES, the supra-regional attention increased significantly.
The contract design was simple, but the circulation pump installers partly tried to encroach the programme for their advantages (for example by trying to increase prices too high).
The payment design as part of the energy supply bill was easy and understandable for the customers.
Benefit to the customer are the savings of electricity of 10% in the long term.
