@glyn.hudson I see the MID meters are IP65 rated, is the recommendation to site them outside in the pipework right next to the pump?
I saw on YouTube yours is indoors a short distance from the HP, this made sense to me that the joints are not external and subject to weather degradation and heat loss vs straight lagged pipes outside.
If I can get hold of Octopus to get answers to open questions and join the cosy club happy to contribute some data.
No, I would recommend the heat meter indoors as close as possible to where the pipes enter the property. You want to heat meter to record the heat entering the building. Heat loss from external pipework should be relativly small if it’s properly insulated, but it’s obviously a good idea to keep external pipework as possible
What does the MID meter data report for these periods? Please post side-by-side screenshots
Here’s a datapoint for the Cosy 6 in Thurcroft
Our MID monitoring for this unit started in March 25, the unit was installed in Jan 25, so we would expect our monitoring to show a higher SCOP since it missed out a lot of cold weather running in Jan/Feb. However, the Octopus scop is over-reporting by at least 9.5%
