Is your house more sealed than a typical new home? I live in a new home with an HRV system (all new homes here have them), but I always assumed they were required for issues related to condensation and humidity, not oxygen levels.
- Xeoncross 9y agoMy house is much more sealed than a typical new home. Every crack was sprayed with foam and every sheet of OSB/decking was taped, then the house was wrapped in ridge foam panels and taped again. Then it was wrapped in house wrap. The weep holes on the windows, and front door, and the venting for the stove and bathroom are the only source of outside air. There is no attic. http://tinyhousemansion.com/ http://tinyhousemansion.com/ Most homes leak plenty so HRV's are mostly about recovering costs and helping with condensation and humidity since they are designed for cold weather.
- brandon272 9y agoOh! I watched your tiny home tour a while ago! Yes, I can see why your definition of a well sealed home is likely a lot different than what would be considered "well-sealed" for a typical new home, as well as why concerns about oxygen and CO2 are a factor. I mentioned that HRV's are essentially standard where I live, which is in Canada, so I think our largest concern here has to do with condensation which can quickly become an issue in any non-drafty indoor space in our extremely cold winters. If the HRV is not set high enough in the winter, ice will build up on the inside of our windows and then melt into the wall structure, causing potential issues.
