Heat balancing between poorly insulated and well insulated parts ofhouse
In our house it's much harder to heat the kitchen than the other rooms
mainly becaus it is in a separate single story section at the back with 3 exterior walls and poor insulation in the roof. To heat the kitchen properly we need to have the boiler on quite high which makes the other rooms too hot. I tell my missus we should keep the boiler on high and turn the thermostatic valves down in the other rooms but she thinks this will use a lot more energy than turning the boiler down and having the thermostatic valves fully open in the other rooms and put up with the chill in the kitchen. How can I explain to her that she is wrong? |

One thing you may find helpful to explain to your wife is that (to a first approximation), changing the setting on a TRV does /not/ change how fast the room heats up when it is too cold. Thus, even when you have the boiler turned down, you can turn down the TRVs, and it won't make any difference (until you set them too low of course). You can then turn the boiler up a bit, and the extra heat will go into the kitchen (because the TRVs will switch off). |

TRVs shouldnt delay room warm up compared to a room stat alone, but IRL they do, because theyre not really thermostatic in the literal sense. Instead they open and close over a range of several degrees, meaning they slow heating down when it gets near to set point. They're an improvement on manual valves, but calling them thermostatic is slightly too optimistic. NT |
