Hi. I am new to forums so please bear with me.......Could anybody offer some advise on Central Heating boiler settings. I have a 14 year old Ideal Classic gas boiler and cannot decide if it is more economical to have the boiler thermostat setting turned down low or up high in these cold winter months. I have thermostats on most of my radiators that are mostly on a high setting, and the thermostat on my hot water tank is set at 60 degrees. I have had the boiler setting turned down low over the past week and the house generally is OK but am I burning more gas this way ? Any advise would be appreciated......
