Hot water coil in furnace duct
I'm looking to install a boiler in my home to replace my furnace heat. I still want to keep the duct work so I can utilize my air conditioning. My plan is to have some infloor heat but I also wanted to install a hot water heating coil in my main supply duct to provide heat for my home.
My question is, will this coil provide the same btu output that a furnace heat exchanger can produce? Am I going to have the boiler set to 180 just to keep up?
I want to have the boiler turn down as much as possible and modulate as necessary.
