[QUOTE="f0ster, post: 7785587, member: 66372"] I presume the heat exchanger is a plate heat exchanger (phe) these have a hot end and a cool end so the flow has to be in opposite directions if you know what I mean, what has changed recently, anything? you should have a pump on both sides of the phe, one to feed the phe and the other to take the heat from the phe to the property, are these both working, put your ear right up close to see if it is turning or just humming, these phe can be prone to block up internally especially if you do not have a magnetic filter fitted, we usually remove them and fill them with hypochlorite for a couple of hours then pressure wash them out, do not leave the hypo in too long, it attacks the brazening, [/QUOTE]
