Attached is my master bedroom idea / plan.
The red boxes are were I plan to locate the radiators.
Location: Freedom, NH
Design Day Temp: -9°F (Manual J)
Heat loss: 10kBtu/Hr (at -9)
I have a Mitsubishi mini-split AC/Heat unit for summer and knee seasons - but I figure by 10°F it is insufficient and not worth anything by -9.
So, I am looking for panels to cover the 10k required.
Downstairs and basement are all radiant floor heat. Lightweight gypcrete over-pour. The water temp on design day is 126°F.
I think a pair of these Beacon Morris BM-22-24X56
radiators and a BM-22-24X36 covers my needs.
I will be using ODR. The plan is to let the upstairs run whatever the ODR says is correct temp for the main floor. There will be a thermostat upstairs, but an in-floor temp sensor control for downstairs and basement. Three zones total.
Does the placement of the radiators look ok?
The wife and I like the bedroom cooler. So we don't care if it cannot maintain design temp on the coldest nights. I just don't want any water freezing.
