In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
A church has low pressure steam radiators that are partially recessed in exterior walls with an exanded metal cover. To me this is a pretty inefficient installation. Any one have data or experience to back this up?
I'm looking for a way to provide a more efficient system for the space. Ugrade the steam system. Maybe replace with hot water (but if the radiators are converted, something would have to be added).
