Hi, I have an oil fire central heating boiler, with a pumped radiator system and convection hot water. Over the weekend the hot water loop packed in completely. Central heating is fine, the 1" pipes off the boiler to the hot cylinder are hot for about 1 M and then cool down, I can find no leaks and everything else seems fine.
Any advise appreceiated.
