"What will they think of next?" bahaha
Rheem did a system like that way back, except for the ERV/HRV part.
Most Ive seen are in small condos. Most 50gal gas water heaters have a
max 40K btu input. You'll need a water heater specially designed for
that application if you want 60K+ btu or more. The water side of the
coil needs to be valved and flushed properly each year to keep it
working properly. When it klunks out on you, you'll have no heat in
your home and no hot water in your shower.
To me that would suck in the Canuck area.
Id pick something to heat my home and something totally separate to
heat my water.
