Title: 1st. Floor hot water is cold? Post by jaggiethistle on Jan 21st, 2010, 9:42am Hi all. I have a Potterton Performer 28 Combi boiler fitted in the kitchen. Over the past week i (and the missus!) have noticed a gradual drop in temperature of the upstairs hot tap water. It's now at the point of being luke warm. All radiators and other taps are fine throughout the house! Any ideas?? :-? |

Title: Re: 1st. Floor hot water is cold? Post by jaggiethistle on Jan 22nd, 2010, 12:43pm Thanx for the reply folks! My water pressure is sitting at a constant 2.0 Bar when the heating is on. Is this ok? I do have mixer taps fitted to the bath and h/w basin. But is it likely that both of these would pick up a fault at the same time? and can you service them? I also have a mains fed mixer shower. I've isolated the cold supply this morning to the shower and turned the lever to full hot and it's still luke warm with just a moments rise in temp before settling back down to cold(ish) :-? |

Title: Re: 1st. Floor hot water is cold? Post by thescruff on Jan 23rd, 2010, 12:20pm The gauge on the boiler is system pressure and not the mains pressure, and 2bar when hot is ok. Try turn the cold to the bath off and running the hot, at the same time measure the flow rate into a bucket, it should be 10-12Ltrs/m |
