I guess Canadian insurance companies are tougher on stuff like that. I know ours might not
cover a claim if they could prove it was a result of something I DIY-ed. Thus, the "Devil's Advocacy"
on stuff like this. I have to think that way, because it's my reality.
You guys have many advantages, when it comes to not being overly "nannied" on a lot of things.
I hate being told "no" or "don't do that" because something bad happened to someone else, maybe
because they did something stupid and caused themselves the grief, but now it affects the way the
insurance companies look at every new situation, including mine, but that's what it amounts to.
Somebody does something without thinking it through first, and it screws it up for everybody.
Good luck with your mods. I do like the fireplace one, even if it might seem like over kill to some.
You live in your van, so I don't think it is for you.
The HWH would only be useful, if you use a LOT of hot water. That was why my NG repair guy
talked us out of it for our house. Since there's only 2 of us, he said we'd never (live to) see any
cost savings. At 3 times the cost of a tank HWH. (seriously, he said we wouldn't live long enough
)
In a small van, the space savings of a tankless HWH, might be worth it.
