i was curious if anyone knew anything about installing a gas water heater in a crawlspace. originally, i believe the builder of my new home was going to install a gas water heater in the crawlspace. is this a proper or recommended installation? i'm assuming that they were going to tip the water heater on its side? (the crawlspace is only 3-4 ft. tall.) they've now called to tell me they're switching gas water heaters to electric water heaters for all houses with a crawlspace. the builder hasn't called me back yet so all i can assume is that they had problems with having a gas heater in a crawlspace. i of course am upset that they are switching me to an electric water heater because of obvious reasons. should the builder have even considered installing a gas water heater in a crawlspace to begin with? i'm wondering if i have a valid case for demanding they make space (in a closet, etc) in the house for the heater instead of changing the type of heater? they guaranteed that any replacements would be the same or better. this to me is NOT equivalent. any thoughts on this would be GREATLY appreciated. thanks.
