Their questions were;
1. “Why in traditional heating design do we heat a mass of water to cool it down again for delivery”.
2. “Why not heat just what is required and deliver it from an energy store at the temperature we want and when we want it”.
3. “Why not do this with as much low grade, low cost renewable energy as possible”.
Based on these queries and over a 15 year period, Ratiotherm have developed a true layered reservoir energy storage system that provides a compact and an ultimate energy efficient solution for integrating multiple and varying energy inputs for the small domestic household up to a large commercial application.
