Venting: The exhaust/combustion air vent is tested and listed for the unit and you can't use any other vent. It uses outside air for combustion and is very safe. The direct vent sealed combustion vent allows Rinnai to be installed in bath rooms and bed rooms where traditional B-Vent water heaters cannot. There are limitations of how far away and were you can terminate the vent, check out the installation manual for that.
Hot Water: It will make endless hot water until you turn off the tap, a minute, an hour, a week. It can only supply so much at a time, depending on your cold water temperature it will only run two or three fixtures at once. It is an `on demand' water heater, not an `instant' water heater, hot water will take longer to arrive at the fixture than it will from a tank water heater.
Gas Supply: These water heaters use less fuel than a tank style water heater but when they want fuel, they want it now. Your tank style water heater required a gas supply of about 40,000 btu's per hour, your Rinnai will require 180 to 199,000 btu's per hour. Check you gas supply lines to make sure they have enough capacity for the new load or your new water heater won't perform to its potential without upgrading the supply line.
Expect some maintenance: This is an energy saving, high tech machine with a combustion fan, pc board and electronic solenoid valves to control water and gas flow. Your water quality will also determine how often the unit will need to be flushed, generally every one or two years.Read more ›
First shower tonight right after install. Plenty of hot water. Can't speak to fluctuations as it was still clearing air in the lines. I gave it 4 stars only because it is too soon in ownership to award it 5 stars. More later...assuming I can update this later.
Jan 23, 2012 Update:
Update: It definitely takes a little longer to get hot water (30 seconds-1 minute). Of course once someone gets hot water upstairs the first time in the morning the lag time isn't really noticeable. And there is a "cold water sandwich" effect as mentioned on the Rennai site. I tend to get wet (turn water off), soap up, wash, (turn water on) and rinse. When I turn the water back on there is a short burst of cooler water. then right back to hot. This is more a function of how I shower but it is a consideration. Of course if you leave the hot water on it stays hot and you never run out. No issues with multiple showers - washing clothes - running dishwasher. It really delivers the hot water. I have a 5 person household (with 4 women).
So I recommend it. Even with the slight delay I keep thinking about all the time I am not paying to heat and reheat water. No real data on cost savings yet.

It wastes a monumental amount of water, I takes a gallon to the first floor faucet which is almost directly above the unit, I would never buy a Rinnai heater again. Read morePublished 4 months ago by Dickydoo
