Recessed radiators with limited insulation
I'm switching from steam to water based heating system
My house is made of brick on the 1st floor and stucco on 2nd floor.
I want to install recessed radiators everywhere to save some room, but since I have stucco on the 2nd floor, the thickness of the exteriors walls are no more than 2 inches (max).
My plumber suggested that I DO NOT install recessed radiators on the 2nd floor as there is a possibility of leak or crack. When I spoke to others, I was told as long as its insulated properly (including polyiso foam behind radiators and spray foam under windows), than it should be fine.
In addition, when I checked the OCS website, it says that if you recess the radiators, then buy 20% more sections (but should still be fine)
The Governale website is a little weird, but i think it says to use 10% more.
The house is located in Queens, NYC, where temps can reach -5 in the deep winter.
The plumber is planning to use Pex to connect.
Please help....thank you in advance!
