The owners manual for my Takagi Jr calls for 3/4" for up to 50' if I remember right but the company I bought it from said that they had no problems with operation using 1/2" out to 50". When the inspector came out he said it should be 3/4" but he wasn't going to make me change it if I felt the unit would work OK. At that time I got the feeling that they were just making the changes in the code book that required 3/4" and I got into that gray area. I've taken a shower while the dishwasher and washing machine were both going and never had a problem of running out of the hot stuff.
BTW my run from tank to heater is about 20' or so.

Here in S. Fl. the per pound cost of the propane depends on the size of the tank. The larger the tank the cheaper the propane, considerably cheaper. I'm getting ready to have my 250 gal removed and replaced with a 500, possibly a 1000 but I'm not exactly flush with cash at the moment. Also, the price varies between distributers, so frequent price comparisons are worthwhile. You can rent or buy a tank. The problem with renting is it's harder to negotiate rates if they own your tank as you're stuck with that distributer. My house is all gas. Maybe someone can tell me if it works the same way on the island.

It's a little different here. You can rent a tank but if you buy one they generally won't fill it. That information as of the time I built my home 3 years ago. I have no information that the situation has changed.
Also, here if it is delivered it is MORE per gallon than if you take tanks in to be filled.
I am using my 28 gallon tanks and it works out fine. Fill one about every two weeks, but we have two showers, a gas clothes dryer and a stove on it and are not particularly frugal. Many people I know get away with 5 gallons a week.

Wow - we have just been working with this as I said. The gas line should be sized to what other appliances might be added also to the gas line.
You need to be careful that what size your WH will run on will not be too small when you add a gas stove, dryer, etc... unless of course you don't care about "moving sand"... i.e. taking out the small line and replumbing the larger line to accomodate more items.
The chart I supplied the link for has a sliding BTU scale so you add up all the BTU's (WH, Stove, dryer, etc) to get the total and then find the distance and calculate size.
I would hate to buy the great stove after the fact that you can get a high flame on and then not be able to get that flame because there isnt enough gas even though when your WH went in it was enough....
The cost difference between 3/4" and 1" is small.
