Heat exchangers are a big one, but they are not yet that common in the US. They are used to pre-heat the makeup air. I'm looking into one atm as part of a HVAC upgrade as currently running a bath fan with all the windows closed will draw air down the chimney.
- bluGill 4y agoHeat exchangers have been code for more than 20 years. Maybe not common, but only because there are a lot of old houses. Or maybe where you live didn't adopt the new code?
- giantg2 4y agoI have a house that's less than 20 and it doesn't have a heat exchanger. I haven't heard of the new construction around here having any. Perhaps it's only in certain states?
- bluGill 4y agoI'm most familiar with Minnesota of 20 years ago, which being a cold area does tend to adopt cold weather codes quicker than others.
