I hadn't , no. Cheers.How Underfloor Heating Works | John Guest Speedfit - https://www.johnguest.com/speedfit/underfloor-heating/underfloor-heating-explained/what-is-ufh/I[/URL] confess my background is electrics, not plumbing. What I don't understand is that the heat store appears to have only one coil, which takes incoming mains pressure cold water, heats it and feeds it to the taps. Apparently the UFH is connected to the same coil. Surely that means that water from your hot taps could be mixed with that running through the UFH pipes, unless there is some sort of hydraulic separation somewhere. It doesn't seem a very hygenic arrangement. I would be interested to hear others observations.

(probably not an experiment to do at this time of the year). The presence of the energy monitor is still bothering me
Communal heat-pump system heats Gateshead apartments
GOING GREEN IN GATESHEAD - DIMPLEX COMMUNAL HEAT PUMP SYSTEM WARMS APARTMENTS
" Heat meters in each apartment can be remotely read, so that each owner pays only for the energy they use"
This second article has this added text
"The nine LA 28 AS air source heat pumps are arranged in two separate banks and provide heat to all apartments, which are arranged in three blocks. The innovative solution was specified, designed and installed by Dimplex heat pump installer partner Azure Natural Energy Systems and was completed in late 2009. Matthew Evans, owner of Azure, explains: “We looked at all the alternative renewable heating systems available, including ground source heat pumps, water to water heat pumps using heat from the River Tyne, biomass and solar thermal combinations. The most cost-effective solution was this communal air source heat pump system to deliver heating to the buildings, with domestic hot water served by individual, electrically heated cylinders"
