Radiant Floors and Air Conditioning / Filtration
I’m sure this topic has been beat to death but figured I’d post it anyway in case somebody wants to smack it some more. Whole house slab w/ radiant heat. Wood stove is main heating source. I need to add A/C. This is a single pitch sealed roof assembly so not a ton of room for ducting but I can design in soffits. I’m just trying to find the least redundant system. I was looking at Zehnder but the price tag seems out of whack compared to Panasonic and Fantech. One of the biggest motivations for the system is to be able to run A/C and filter outside air during fire season. In the winter we ventilate the house a lot opening windows/doors, but it would be nice to have fresh air automated. Still not sure if HRV is better than ERV in Northern Idaho Climate zone 5b-ish.
As of now I’m leaning towards the following separate systems but I’d love to hear feedback from people that have gone through this:
– HEAT: Radiant floors/wood stove
– A/C back up HEAT: 3 zone mini split
– HRV/ERV: Separate ducted system w/ carbon filter for fire season.
– KITCHEN: High CFM fan w/ makeup air.
– Bathroom fans? Maybe HRV/ERV deletes these.
