I was watching YouTube, and it auto moved to next video, and some guy was saying how we should heat the whole house, and heating room by room was a bad move, as heat moves room to room, I have seen the chimney effect on the stairs with some houses, so I suppose he does have a point.
I suspect size matters, I have also seen where thermostats and thermometers have shown vastly different temperatures within the same room. Never mind room to room.
I remember being told, fit the thermostat in a downstairs room (as heat raises) with no outside door, or alternative heating, and in a room not kept too warm, so as summer arrives the heating will auto stop, it then went on about how the set the lock shield valves to regulate how much heat to each room. I tried, and it simply did not work, as upstairs room temperatures were altered so much if a door left open or closed.
So upstairs all radiators with TRVs to stop bedroom over heating if door left open.
He was correct, very little insulation between rooms, but I was born in an era when only down-stairs rooms had fires. And bedrooms were heated by the heat from the room below. But this means even today, I want the bedroom cooler than the living room, and I see no point in heating a bedroom at 9 am as will not be used until 10 pm.
I do see a problem splitting a house into just 2 zones, one is likely some rooms in each zone will be either not used, or used at different times to other rooms in the same zone. And two, with a modern modulating boiler, nothing should turn on/off, every control where it can, should be analogue and turn up/down, and no real point having zoned zones. i.e. if using TRVs then no point in zone valves as they do the same job.
OK, there will be exceptions, my flat is hardly ever used in winter, so a zone valve does turn it off.
But I have 14 programmable TRV heads, and each room has times and heat levels adjusted to suit what the room is used for. I allow bedrooms to cool during the day, and living rooms to cool overnight. And I have three devices in the main house, which can turn the boiler on.
He was saying all this is wrong, and I should heat all rooms 24/7. I can't see why?
