We had an approved heat meter installed, electricity meter on the heat pump with wifi connectivity, an additional electricity meter with wifi to the import supply, and several temperature sensors around the house. All data was sent to a router communication box and back to the trial organisation. There were manufacturer approved modifications made to the heat pump to start/stop and set differing flow temperatures.

The system worked very well: all we had to do was to set the desired comfortable temperature.

I also got the weekly data from which I worked out the weekly SPF. I could also separate the heating component from the DHW component.

In terms of results, we had a design SPF of 3.1, a working SPF of 3.2 using the manufacturers set up and SPF over 3.4 for the trial system.

Unfortunately, the communication electronics were not reliable and packed up 12 months ago. There does not appear to be anything out there to replace it. Moreover, the trial organisation decided not to proceed with any further development.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15688&Focus=267760#Comment_267760 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15688&Focus=267760#Comment_267760 Mon, 23 Apr 2018 13:48:48 +0100 RobinB http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15688&Focus=283669#Comment_283669 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15688&Focus=283669#Comment_283669 Fri, 02 Oct 2020 18:38:47 +0100 ComeOnPilgrim
