Backup heat source
I was under the impression that there was a northern Minnesota requirement to have a backup heat source. When my home was built, I was told that the Steffes hydronic boiler that was installed at the time would satisfy the requirement because it stores heat.
Is this an actual requirement?
If so, is this about energy sources or about heat sources?
If it’s about energy sources and the power goes out, having a backup system that also runs on electric would not satisfy this but having a generator might.
If it’s about heat sources and my Steffes goes on the blink, then having another electric heat source would satisfy this.
If it’s about both, then the backup generator in combination with a backup heat source could cover both issues.
It’s my desire to not include propane in any of those scenarios, other than to run the outdoor generator.
