We have an Ideal Icos (H15 - I think) with the warm weather coming I turned the room thermostat down to 17 last night so the central heating didnt kick in. Woke up this morning to no hot water. Surely the room thermostat would not control the hot water ? The cylinder is set to 60 and the control panel shows "ON"
Any pointers please !!
