central heating works sporadically
Programmer time comes on for heating and hot water, boiler fires up sometimes and also sometimes i get hot water but no heating. May be ok but not the next , any ideas as to what the problem maybe ?
Had similar checked.....due to damp in wiring joint outside? All fuses & trips ok; boiler fires etc as you stated above then pffft! Wait half hour.....switch on & 'hold your breath' :(
