just a curiousity question for now. say i'm able to compleat a loft over my garage. i'm thinking no more than two people being accomodated as far as someone living there, with a smallish kitchenette and full bath room. what size water heater might be best for something like that? also, my house has a gas water heater that seems to work well enough, but is there any advantage to having an electric water heater to go with a gas one in a situation like this where you'd have two (the loft is over a detatched garage)? say if i lost gas or electric for whatever reason i'd still have hot water from one or the other? we have a habitat restore here and i think about stuff like this in case they get something i can use for a good deal. i can grab and hang onto it till i actually make a try at compleating the loft. thanks for any help.
