Ideal Isar HE24/30

Hi All,

I have one of these boilers at home, and have noticed recently, the hot water hasn't been working right. The PCB was replaced about 9 months ago, and the Gas Venturi Fan was replaced 12 months ago, and all has been fine on the heating side, but i'm struggling to get hot water out of it. The hot water will flow warm for a couple of minutes, not hot with the dial up full, and then go cold again while even the central heating is on or off. The only thing I could think off the top of my head, is that since the PCB was replaced, since it was upgraded revision from the one that came out, is it possible a jumper on the PCB isn't set right?

Otherwise, what would cause this problem?

easiest remedy would be a sledge hammer to the boiler and a replacement

I doubt it will be anything to do with the PCB, more than likely a diverter valve issue. You need a RGI to take a look at it I'm afraid.

Could be a faulty diverter valve or blocked heat exchanger - although I'm sure one of the other GSR's with more experience will be along shortly.

I take it that all work has been carried out by a registered gas installer?

Yes thanks.
