Central heating boiler

[boiler]

The boiler makes a banging noise when heating up the hot water .Sometimes it fires up but does not warm any water sometimes it does.If i put the radiators on the water gets warmed every time.Any ideas to what the problem is ?

I can tell you what the problem is but as you're not corgi you don't want to be touching it.I suggest you get in touch with the "professionals" so they can tell you a load of garbage and relieve you of that rainy day money good luck my friend!
