my oil central heating is not turning on when I turn the thermostat up. It does come on but only when it wants it seems. Hot water works fine.
I replaced my drayton t45 thermostat with a Honeywell t6360b ( I presumed they were interchangeable) and this has made no difference. All used to work fine (for the last 10years) . The programmer is a lifestyle acl lp241. ive have tried all the timer setting with the programmer and it seems nothing I do will make it come on. Any help guys . thanks
