“EndoTherm has been added to heating systems in 2 of our smaller properties for approx 2 years. The gas savings realised have been of the order of 10-13.5%. The results are there to be seen. When circumstances allow, this product will be added to the main site heating system. Everyone connected with the company has been friendly, professional and helpful at all times and a pleasure to deal with”
