Hi All,
Just wondered what your take was on the following. I moved into my property 2.5 years ago. The boiler fitted is an Ideal iStor - I know they have a bad reputation but mine is serviced yearly and it hasn't caused me any problems to talk about really.
Anyway, the house did have an old lead supply which has since been changed to a new plastic pipe mains. Since then (over 6 months now) I've not noticed a difference at all in flow rate - if anything its worse than it was.
I've determined that next to my mains inlet is a PRV set to 2 bar yet I believe the house is receiving far in excess of 2 bar as it was measured on installation - I just cant remember what it was. On reading, the boiler manufacturer indicates that the 2 bar setting is indeed correct. The boiler advertises a flow rate of up to 35LPM and around 11 on an empty cylinder. I get 8/9 LPM - and that's on the taps next to it! All other outlets are the same as the house is limited from this PRV. Every pipe seems to be 22mm copper.
Now what I don't get is that I can manually increase the pressure on the PRV and the water flows much better to a point where the shower is great. However, the tudish begins to drip water assuming the pressure relief valve is giving way. So, if I set the PRV off the mains the at 2 bar (which is exactly how it is indicated in the ideal installation manual) I get poor flow rates. Why would a supposed mains fed boiler be limited to 2 bar? Should I actually be getting better flow or is this actually quite good?
I've ordered a new PRV and am just waiting for it to be delivered before i can try and fit it- I assumed something was wrong with that. Incidentally, the boiler company are not interested (as its not actually the boiler unit) and the last time they serviced it said there were no faults - the bloke actually didnt know what the PRV was until I told him!
Any advice would be appreciated. Thanks
