I’m thinking of implementing some changes in the heating strategy of my parents house. I excuse my self in advance for the lack of vocabulary with some words.
In winter it usually doesn’t get colder than -5°C.
So my parents have a 3 story house with additional story that is the basement where the boiler is located. The house is touching the neighbouring houses. We have a programmable thermostat in the living room in the ground floor. Finally, all radiators have a manual knob, but I’m not sure each of the radiators pipes are independent the one from another. that means if closing the knob from one radiator means condemning the flow on the others, but I highly doubt it.
As it was said before the only inconvenient of setting the temperature very low when people are away is that it takes time to bring it back up when needed, so trials and errors must be made especially if we don’t have a learning programmable thermostat right?
So what is the best way to know how much time it needs to heat up? should I make some calculations or should i just test it? What temperature should I let the house cool down to before starting the test?I also guess that external parameters like external temperature and wind speed will affect the heat up time, but will it affect it alot?
Secondly, I’m not sure about it but I think that the radiators in the ground level are hotter than the ones in the top floors, so when the living room ideal temperature has been reached, the system shuts down and the rooms are still a bit chilly. I tend to think that if I turn down the knob on the radiator on the ground level, that the heat emitted in the 3 floors will even out. Is that right?
BUT, I’m afraid than when I will leave my parents house to go back to my country where I study, if I turn the knob on the radiators in my room in the third floor the system will not perform efficiently since the water coming back to the system from the ground floor (living room) will be hot.
Sorry for this long question.
