Oil boiler is cycling on/off/on and hot water returns to boiler before it turns off, two pumps, two motorised valves micro bore main house 15 mm flat, flat works fine, main house hit and miss.
So tried each radiator non have really hot water on return pipes, radiators do get hot some times, but seems hit and miss, all TRV bases change when I moved in 4 years ago, all heads except toilet shower room are electronic all software say batteries OK, three makes of heads, Energenie, Kasa, and eQ-3 latter bluetooth version, main wall thermostat is Nest Gen 3, which is not turning off, so living room now Energenie 17ºC heating to 22ºC radiator cold, Kasa 17.5ºC heating to 23ºC radiator cold but some times the radiators do warm up, tried bleeding no air found, when flat motorised valve opens the main house seems to get warmer, I hear the pipes warming and cooling so water is getting through some where, when we moved in no motorised valves and which ever pump ran the water would flow in reverse through the other pump which is why valves were added.
If it did not work, could likely work out fault, but it works some times, and the old smashed TRV head sitting on mantle place is showing 19ºC so living room is heating up, but intermittent.
Age concern is sending some one around a week tomorrow, maybe he can help, I tried balancing radiators when I first moved in, just made it worse, so living room lock shield valves are now wide open. top floor bathroom is therm-syphon as is DHW with it seems no way to regulate flow.
I have not found a by-pass valve, but the flat use to be a garage under the main house, and the plaster board now hides pipe work and wiring. I really don't want to rip plaster board off the walls, the pumps are on the return so can't see how a by-pass valve would work.
At the moment the pipe to lock shield valve in living room is too hot to touch, Energenie TRV side just taken the chill off pipe, radiator just the chill taken off it. When the Energenie TRV's work you can hear them, and I have not heard them work except at 12 midday Saturday when set to exercise.
As said if it did not work full stop I am sure I could find out why, but this intermittent operation is driving me crazy. As I have been writing this the living room radiator has been getting ever so slightly warmer. But pulling my hair out trying to work out what is wrong.
