Reliability and smart design from Volter

After reviewing various CHP technologies on the market and after seeing the Volter 40 Indoor unit in Japan, Keiwa were convinced of the reliability of the Volter unit and in how the supply system and energy distribution systems are organized. They saw the Volter 40 Indoor smart design adding marketing value to the company.

Excess electricity is sold onto the grid and the heat is demonstrated onsite through heating a greenhouse and a footbath, incorporating an element from traditional Japanese culture.


This installation was done by Volter´s distributor in Japan, Volter Japan.
