I'm curious... the way I read the code, the first links listed are incorrect... as of Jan 2010 for new construction water heaters are required to be solar...
UNLESS
...you live in an area which does not receive enough days of sunshine, in which case you can apply for a variance to use these tankless heaters.
Can anyone verify? Personally I'd like to install solar with one of these propane tankless heaters as backup for long grey stretches of weather (in Volcano)... not sure what the Building Dept will have to say. Anyone know?
