Im going to be fitting new for old. the only thing is the existing system has gravity primary's. I am going to fit 2 zone valve's but i am looking for advice on where to fit the pump as i know it can cause problems.
This boiler keeps losing pressure. on inspection i noticed the blow off is dripping constantly. At first i tried to check the expansion vessel, the valve would not let air in or out though. Need some help with what needs done guys :roll:
I was looking for a boiler to replace and old one. The system will still have a hw cylinder. In a brochure i have there are system boilers and heating only boilers, whats the difference
I recently had this problem, the drain valve on the cylinder was broken. I disconnected the top connection and siphoned out as much as i could then lifted out the cylinder. Is this the easiest way or are there other methods
