what is wrong with boilers when not heating ?what is the problems is with central heating ? is the insulations not found lose heating ?leakage ?
I take it that your central heating's not working. A boiler heats water that can be 1) pumped to a hot water tank for use in washing/bathing 2) pumped around radiators for central heating The reasons for no central heating (if the boiler is actually heating the water) include 1) pump not working 2) air in pipes - bleed the radiators, get a bleed key from your local DIY store 3) blocked/corroded pipes 4) leaks (but you'd probably see water somewhere)
