Middlesex County, Ontario | It's what I was told by the installers when we built my parents' new ICF/in-floor house. Now that I'm looking for an actual source, I can't find one, so I think I might be mistaken.
What's probably the case is that
- code requires an HRV/ERV
- most people want AC
- code has some ducting requirements for air exchange
- If you have a full ducting system in place already then adding a radiator and pump and one more zone isn't a big cost adder overall |
