Thanks

Good progress! I would want the gas bottle disconnected and moved out of the way during the lifting process, just in case it all goes wrong! Have you considered using a Genie Lift?

Hello Glyn, thanks for the comment,.... yes i am waiting on delivery of a 1m propane pigtail to get the cylinder outside the scaffold tower structure. I plan to lift the unit 0.5m at a time, then place the scaffold boards under, so it's never more than 0.5m from a solid base. I didn't consider the genie,... well maybe look again, thanks for the suggestion.

I am currently doing a self installation of valliant arotherm 7kw. I have tested it on the hot water tank and all ok so will move onto removing the combi boiler. Is yiu outside isolation point outside the protected zone. Keep up the good work

Thanks for the comment Derek, the isolator is about 1m from the centre line, so is on the edge of the zone. The diagrams are a bit ambiguous, I used dim A (2.1m) about the centre. Did you change the water tank or are you running with the original, as I am doing initially (until I discover the coil is not big enough)?

flow meter on the return , temperature sensor on the flow maybe expected by default settings.... you can probably change it in the settings

Yes I hope so,.... i did read somewhere meter on the flow,....oh, you'll see at time 0.25 there is a sticker on the flow meter and it is to be installed on the flow.

Heatmeter bodys can be fitted on either flow or return, historically the meter body was usually fitted on Return to avoid high temperatures, this is not an issue with heat pumps. Ultrasonic heatmeters like this Kamstrup work best with the body fitted on the flow, this is how they are configured by default. But this can be changed in config settings if needed:, see:kzread.info/dash/bejne/pmagpMWRhqSrd84.htmlsi=CzasLKU-5_4P5t6B

@@GlynHudson Thanks . Just one thing , I was helping some local installers with OEM shop kit and noticed included instructions to put flow meter on flow but the meter was actual setup the other way around resulting in negative flow reading . Sontex 789 was set to "Coldpipe" . Its just FYI .

@@gopikrishnayogarajah sorry for confusion, Sontex superstatic meters work best on return,but can be configured for either. Going forward we're standardising on ultrasonic meters which will be configured for the flow..

Not sure those returns are correct

@@TheFredbackLoop been a heating engineer for 20 years and I have never seen returns connected together like that the hot water circuit should connect directly to one port and heating circuit to the other. Probably would work but it’s not right

My DHW and zone 2 (upstairs) share a common return. The zone 1 (downstairs) is also commoned with the Z2 return. The 3 flows are separate. In an ideal world I would rectify this but that is the way is it for now. I do know that I have a bit of spurious circulation on a couple of upstairs rads when the Z2 valve is closed (so Z2 supposedly off) and the tank is being heated (DHW on). Thanks for the heads-up.
