I put a propane one in 5 years ago and love it. I think mine is rated at 9.5 GPM and you will never run out of hot water. I went into the extended menu on mine and cranked the sucker up super hot.

I think it may take a little longer to get the hot water to the faucet but who cares, water is cheap.

Mine is a Rheem/Ruud 80% unit that uses a metal vent. I wish I would have picked up the 90+ model but my plumbing sales guy talked me out of it...probably because he didn't have one. I had to run 3/4 pipe to mine also. You can also get one that mounts on the outside of your house and don't have to do any venting. My stove is also propane and I have to fill my 125 gallon tank about 2 times per year at about $150 each time.

I have had no issues out of mine and only cleaned it one time since I installed it. I pumped vinegar through it for about 1 hour with the heater turned off.

When I go out of town I turn the propane off to mine (and the water to the house). I don't what would happed if you had a hot water line rupture and that thing pumped out 150*-160* water all day long.
