Hi all I’m new to this game. I have Ideal C24 MINI Boiler all been well for about 5 years, then its started to play up, the hot water is working fine, the problem is the central heating system, The system will work all day as long as you don’t use the hot water. Then the central system will not fire up and just circulate water around the boiler, If I run the hot water again the boiler some time kicks back into gear and starts working, this problem comes and goes, Help
