Have a Horstmann gas boiler with 2 x zone central heating plus water heating.
Around this time every year after it hasn't been used over the summer months it gives trouble starting up. This time the lower floor central heating is working fine i.e. rads are heating up but we cannot get the water or the upper 2 floors to heat.
Trying to heat the water and the upper zone results in the unit going to fault about a minute into attempting to function.
Anybody got any suggestions?
Thanks in advance,
