So rest of house, lower floor living room which also has open fire, kitchen, and dinning room, plus shower and toilet.
Top floor two bedrooms plus bathroom, office (bedroom 2), and craft room (bedroom 1).
So three main rooms are living room, office and craft room, these will have wifi TRV heads, likely the two bed rooms with have terrier i30 heads so they are only heated at night and will not over heat. Also likely dinning room and kitchen will have terrier i30 so they are not heated at night.
But don't want boiler running 24/7, I want it to auto shut down when not required, so some where I need a thermostat, it would seem most likely place is in the hall which has stairs to landing,
Landing has no radiator but will clearly be heated from hall radiator that is other option I think?
So seems three options, opposite radiator in hall, on hall side of kitchen to hall wall, or landing, which would be best?
Next is type of thermostat, since central heating also heats water, although at moment no control over water heating, Nest 3 seems to tick the boxes, however that would need a motorised valve adding to control hot water and a thermostat on the hot water tank, and then finding a way to get wires between them all.
Or could have simple Nest e which would simply switch off boiler once house warm. But work clearly needs doing, need non return or check valves adding as at moment if pump not activated then water flows in reverse warming radiators slightly when set to domestic hot water.
There is a programmer, however it does not seem to matter where set, even set to hot water only twice a day, radiators still get hot. There seems to be no direct connection between pumps and programmer.
So as it stands, programmer turns on boiler and domestic hot water is heated, if thermostat in converted garage is set high enough one pump will circulate water around the converted garage. The other pump has a 13A plug on it, and if plugged in, then main house gets circulated hot water to radiators. As a temporary measure I have a smart socket supplying that pump so I can switch main house heating on/off.
Clearly it needs modifying, my knee jerk reaction is fit a Nest e to control second pump, but pumps don't have micro switches, so how do I power boiler at same time as pump. I can add a relay box of course, but would like to use a standard system.
