old steam system replacement
Hi all, I'm trying to figure out the best way to replace my current heating system with a high efficiency system that provides comfort and a quick payback. Every HVAC contractor I interview has a different opinion.
Current system: 35 yr old oil-fired steam boiler, original steam radiators, indirect DHW coil w/ no storage tank. cost me about $2500 in oil since August last year.
House: 1931 2-story colonial in MA. 1750 sqft. Uncond basement & attic, both accessible. No A/C (but I would like it). No access to Nat gas, but propane is an option.
My thoughts are leaning toward some sort of combined system. Radiant floor heat on 1st floor & either hydro-air or multi-split heat pump (ducted) on 2nd floor. This gets comfortable heat in house and A/C in bedrooms for hot summer days, all without tearing house apart. I wonder about the ease and efficiency of doing a combined system like this.
Can radiant floor system act as cooling if unheated water runs through the system in the summer? Does this have any issues? Does using radiant + hydro-air cause issues if running at different temps?
Any other suggestions?
