You can just about make out the hex pattern around the bottom so I assume it would unscrew for me to try and clean it out too - I just sadly don't have the right size adapter to get it out.

I've got a second UU engineer visit booked for a couple of weeks time now. I'm hoping they have similar equipment to this to be able to test the flow rate: https://vernonmorris.co.uk/shop/item/digital-boundary-flow-pressure-test-kit/

Thanks for everyone's input. I ended up opening up that cover (which indeed seems to be a meter fitment). In there I found some stones - one which was stuck just after the main tap, and took a bit of working with a couple of screwdrivers and pliers, and a couple of smaller ones in the "send"...

Mine's even smarter - it actually turns on a set number of times each day when one of us is most likely to be at home :D I think this timer idea should definitely be spread around!!

I suppose there's a change I could badger them repeatedly, however the original bloke who came out said it wasn't something they'd do as this tap is within in my property boundary, in the middle of the drive.

I've taken a picture of the outdoor stop tap: upload image Flow is bottom (street) to top (house). The plastic housing with the hex cap reads "Hand tight plus 1/4 turn". I'm assuming this is just some kind of cap and not a flow regulator or anything to that degree. Any worth in turning off...

Flow path is mains > outside stop tap under the drive at the front of the house > supply pipe runs entire length of house to kitchen at the back > internal stop tap under sink, meter directly after the tap, and then a straight pipe with various taps, including that for the sink and outdoor tap...

Hi all, Having a bit of an issue with our mains water pressure. We had a survey for a heat pump, and had a flow rate of 9L/min measured, described as "pants". Following this, we got United Utilities out who did a similar test - the pressure was "fine" (forgive me for forgetting the reading)...

My thermostats (ESi ESRTP4) are TPI-capable, but I haven't enabled the setting. The fact the house isn't suffering from huge temperature swings and me having manually lowered the flow temperature has meant the thermostats click off at around SP+0.5C reasonably comfortably right now. If I've...

Ah thanks for that - I had indeed read that section but clearly hadn't twigged the pump setting was a permanent one; I'd falsely equated it with the other "tests". Any potential downsides to running the CH pump at 100% all the time, other than increased wear and increased electricity use?

I, stupidly, didn't take a note of that when I was watching burn times. I'll have a look next time the heating comes on.

https://idealheating.com/uploads/documents/Logic-Max-Combi-Installation-Servicing-Guide-222362-1_lowres.pdf It was this manual. However, this is for the "Logic Max" and I have just a standard "Logic", so the manual doesn't cover my model. I think I'm completely SOL when it comes to my system...

As seems to be the growing theme, there's no obvious option to do that on the Ideal's. Unless I need to open it up and flick some kind of switch somewhere... at which point I need a GasSafe engineer as the front panel is head-to-toe room seal.

Given we have no evidence of services, I think it's safe to say any warranty is now gone. I know that'll draw you even closer to there being a fault with the boiler... but on the times were it'd fire for a small amount of time, I did hear the boiler start to modulate back down, so I don't...

Thanks for those workings, as they definitely highlight the issue with oversized combi boilers. As for the anti-cycle time, it appears this is not changeable on the Ideal boilers so I'm not able to go down that route shy of getting a brand-new boiler.

I'm just over in Liverpool so weather shouldn't be too far from yours. My biggest issue is it being a modern house (timber frame with lots of insulation) - I'm seeing the house lose less than a degree of heat overnight even with external temperatures below 10C. Great for the bills overall, but...

100% because the boiler hits the flow temperature. It seems to vary +/- 5C either side of the set point. For whatever reason, it occasionally fired up, and the flow temperature started rising, but I could hear the boiler modulate back, and the flow temperature then only crept up very slowly...

I sat and measured recently, and the firing time varied from 20-110 seconds with a flow temperature of 50C set. This may change as the winter months roll in as it's still very mild and house temperatures haven't dropped much below 18C.

My thermostats can do TPI but it's off by default from the factory. I've not enabled it, and I'm not sure if I will, though I suppose it gets me a "fake" OpenTherm at the expense of actual heating on/off cycling, with an option for 3 or 6 cycles per hour.

I found the service/install manual for the boiler, and it certainly looks like there's nothing that can be set. Service mode only allows for testing of pump speed and max/min firing rates, with no settings available, so all control looks to be firmly baked into the boiler. Never mind! I feel...
