My kitchen is a LONG way from my electric water heater, which is under the floor beneath the downstairs bathroom. I'm thinking about adding a second water heater under the floor under the kitchen sink. (A tankless water heater is not being considered, and there is no inside cabinet space to accommodate another water heater.)
- Can a short body propane water heater be installed in the crawl space? If so, does it have to be vented to the outside, or is venting into the crawl space sufficient?
- Is there any reason that I cannot put a valve going into the hot water line at the kitchen sink that will allow me to switch between the present electric hot water heater and the new propane one?
- My house is plumbed with 3/4" copper, but the line going to the kitchen is only 1/2". Shouldn't that line be upgraded to 3/4"?
- What is the optimum water pressure for the house? My last plumber reduced it because it was way too high. Now it's too low.
The reasons I want to use propane are that we have a large propane tank for our gas logs. We don't use the minimum amount each month, so we can get some of the heating energy for "free". Second, if the power goes out, we'll still have hot water, and our power does go out way too often.
