jfb Posted November 2, 2022 Posted November 2, 2022 Just had my pre plumbed cylinder hooked up. any glaring errors in the install or does it seem ok? lagging is going on tomorrow.
billt Posted November 2, 2022 Posted November 2, 2022 I've no idea whether the install is OK or not but it looks insanely complex. Is that 5 pumps? Heath Robinson would be proud.
Nickfromwales Posted November 2, 2022 Posted November 2, 2022 Looks busy, but the plumbing looks neat / well executed. Too much going on there to comment tbh. “Carry on!”. 1

ProDave Posted November 3, 2022 Posted November 3, 2022 Near the bottom centre is a white flex that appears to be stripped to it's individual cores outside of any junction box. I don't know if that is part of the pre wired bit or not, but the picture when zoomed in is not that clear.
PeterW Posted November 3, 2022 Posted November 3, 2022 Only comment would be that to service and check the potable expansion tank the engineer is going to have to climb over the top of the tank…!! Also, the tundish is buried at the back which makes me think the control group is also buried - again this is a potential service item so should be easily accessible. And is that a cheap DAB pump at the top ..? If it’s one you’ve had installed I would bin it now and save the headache when it fails and put a Wilo or Grundfos in its place.
markocosic Posted November 12, 2022 Posted November 12, 2022 Introducing a plate heat exchanger, especially an uncontrolled one, is going to screw the cop of the heat pump. How on earth is it all controlled and does it have any chance of working better than an immersion heater? Good workmanship is useless if the system design is a dog.

markocosic Posted November 12, 2022 Posted November 12, 2022 I'm aware - however if you stuff up the design it's possible to do not much better than an immersion. There should be no need for such spaghetti - it's probably worth a design/control review as well as a workmanship review if performance matters to you.
