The sun...our caretaker

 

Experiences of the gardening club Alsterkanal e.V. which were made with the TWINSOLAR 4.0, installed on the club house in Hamburg: "After having installed the Twinsolar on our wooden club house, we have noticed after a time when entering the house that the atmosphere is comfortable and the air is fresh and dry, not damp and cold as before.

This has surprised us positively. Also the demand for heating energy has been reduced by 40% per year."
