However the real problem was the lounge radiator was obstructed by the sofa
Yes same here with one radiator, hence why I was looking at the fans, but wife is looking at getting rid of sofa, in the room, three easy chairs, sofa 3 persons, and 6 chairs for dinning table, were moved in when dinning room was used as a bedroom, and never moved back. Not really a small room, L shaped, and shortest wall 5 x Ikea Billy bookcases against it.
But the Myson in old house did not seem noisy in the day, but at night would need to turn up the TV a bit when it fired up.
And I am not sure if the oil on/off boiler is causing the hysteresis or the way the electronic TRV heads work? Today I feel cold, thermometer on table next to PC shows 19.6°C the TRV behind me 19°C, behind sofa 19.7°C and the wall thermostat 20.5°C and set to 20.5°C and heating not running, radiator cold. Did not take readings yesterday, but felt warm, the Kasa TRV will show a graph, as will the wall thermostat


and it seems as if heating is doing as it is told, so why do I feel cold? Maybe because it is a dull day? Phone tells me 8°C which is also what the wall thermostat shows, where it gets it from I don't know, must be the internet in both cases.
If the room was 20°C in the summer, I would be thinking it was hot, so maybe kid ology works?
