Where to put AC ducts on hydronically heated homes
Hi GW -- I have cross-posted this on the building a house forum -- sure hope that is okay.
For those of you who have hydronically heated homes, where did you place your AC duct work? We have been back and forth many times with our HVAC contractor trying to find both an efficient and asthetically pleasing duct placement. I feel very frustrated with the process.
Here are the details on our home:
- Original home was a raised ranch
- 2 story addition was placed on the back half of home (part that looked like a standard bungalow before due to grade)
- main living space is very open concept (except a bedroom, laundry room and bath. Upper level contains two baths and four bedrooms.
- All of our ceilings including basement, main floor and upper floor are 8 feet high
- All heat will be supplied by underfloor hydronic heat
- The total square footage not including basement is 2900
We have discussed using either one large air handler or two smaller ones. My priority is to avoid drop down boxes in the main living area (basement would be okay) as our ceilings are only 8 feet. We are likely going to have one air handler in the new attic over the new second floor and frame that area and drywall in a section so it is conditioned space. We are not sure where to place a possible second air handler, although theoretically we could also do another conditioned attic space in the old attic (the original attic that did not have an addition built over it).
Please tell me what you worked out, and where you had to give up ceiling height for drop down boxing, or closet and/or wall space for duct runs.
I look forward to hearing how others have solved this problem. TIA!!
P.S. Maybe we should look again at Mini-splits
