Hi, I just received the details for the room-by-room heat loss calculation. We will need five new radiators, three in the bedrooms on the first floor. They designed the flow temperature at 49°. I would like to have a flow at 35-40°. Should I tell them now, or can it be adjusted later? Do I need to upgrade the radiators in the bedrooms? Now that they are off, the home is really warm upstairs.

The calculation is for a 4 bed detached new build house (2019) , for midea r290 m thermal arctic ht series 4Kw.

Thank you.
