The THl M75 is available in 5-25 Kw. The combined boiler and hot water unit is the ideal solution for two bathroom properties. The inbuilt 75 litre un-vented hot water, fast recovery tank lifts from 10°C to 60°C in only 10 minutes on the 5-25 model and provides an amazing 160 litres of hot water in the first 10 minutes of draw off and 712 litres of hot water in one hour. Keeping in line with our philosophy to only store a small amount of hot water but to recover it very quickly, the THl M75 is the modern solution for the modern home.
