No i don't, neither do you. I do know it was left in a poor state by a engineer who should know better. No need to defend the indefensible. If it is a pin hole, I'd be putting in a claim for damage and repair as well.

You'd leave a installation showing max pressure would you? Perfectly normal to walk out leaving it like that then? Or are you saying (you are lol) that this magically happened just after the service visit through no fault of the service? You are good at the customer bullshit, I'll give you that.

Exactly.

Where did you read that? https://schneider-electric.zendesk.com/hc/en-gb/articles/360014337977-I-have-an-OpenTherm-Combi-boiler-can-I-use-it-with-Wiser-

Or the "Gas safe" engineer has ****ed something up. Call him back.

You only need the one (trv). But I'd do both and change the other to a lockshield.

Fluid behaves the sames under pressure regardless does it? Ok. I'll just rewrite my fluid and thermodynamics text books :rolleyes:

Yes. I have it. Read my post history and search for "Wiser". Needs a little bit of thought regarding any bypasses but otherwise, its how heating controls should be. Highly recommended

Throw it away.

Give over. The PSV's on these systems are set at 3 bar. You turn the pump on, and you get a pressure rise, Should the system be satisfied (ie the abv wants to open), you are looking at enough pressure to pop open the psv, spurting hot , boiling water and steam somewhere. Let's not kid...

Another example of "Gas safe" quality and safety l. :rolleyes: Ring the Gas safe agency and ask them for an inspection because the idiot who did this left the system in a dangerous condition.

The old one is CS, constant speed. The ups3 is PP Variable speed, although it can be set to mimic the old CS pumps but this negates the benefits of PP pumps. You just need to either install the new boiler with this in mind (you might need a small tweek) or use it in CS mode which i bet my last...

Ymmv. At your own risk. Investments rise and fall. Don't stick your dick in crazy etc.etc.

You might use the wiser set up in the following way: 1) just replace the timer module with the wiser programmer and use only 1channel for on-off timed boiler control. (Call this channel "boiler on-off) link the channel to the boiler as per the existing switch. Use the HW channel as this cares...

Don't run off and buy any pump. It has to match the setup.

And... Check each piece before laying. Flaws stand out a mile. Don't be tempted to force the skirting flush with the floor if you are sitting it over it. It stops the floor from breathing and you get a load of issues. Taking the boards off is the very best way. Using quadrant instead looks...

Make sure you start from the door side. You want good, thick planks at the door. Not 6" butts of 1/4 thick planks. Make sure to figure out what this leaves at the other end. You don't want slithers at the ends. Sort the sub floor out first. Do anything you need to before hand. Make sure its...

One of the few things i miss being abroad. A meal fit for a king.

Ah. Empty bottle. That was the 1st course then? :giggle:

Interesting that the meat isn't the centre of the dish but the pudding is. You must be Yorkshire? Looks lovely but -1 point for purring the gravy over the roasties. I prefer mine salted. White wine for red meat?
