Tankless Water Heaters? Anyone have experience?

another thing to remember volinbham is that they only put out so much hot water at a time (6-8gpm IIRC). Based on what you said I don't think it will be an issue but we did have a couple of customers complain that they couldn't fill their jetted tub, shower, wash dishes, a load of laundry, etc all at one time.

Those customers had to be anal freaks.

Try these: "I'm rubber, you're glue....." or maybe "I'm dumb? You're dumb." They're much more clever and would show some originality.

Why don't we do this. When I make a post trying to be helpful to someone who's asked for information, why don't you just leave it alone and not make an off-the-wall, out-of-contex, comment. Then we can all get along.

No experience with a tankless, but have an on demand one at my house, my 'lectric bill dropped about 15-20 dollars a month.

Well, just heard my first negative comment about the electric type water heaters. Guy I work with said he went to a guys house that had one and it was vibrating and shaking when it was operating.

:blink:

For those who have one, how much amperage is needed for the circuit?

I've never owned one but the only comment I've heard that was negative is that you really need a water filtration system especially if you live in eat Tennessee. From what I've heard they are bad to clog. The one I looked into required 240V, 100 amp breaker.

When I lived in Spain we had these. Every six months would clog so bad with calcium we would have to disconnect, take outside and run acid through it. The clog would get bad enough there wouldn't be enough water pressure to make it kick on. I could never use one of these in southern OH where the water is so full of calcium, even with a water softener.

Got a friend who had one installed 2 years ago and has had no problems. He does not recommend them for people with kids in the house, since kids, especially teens, tend to run them until the hot water is gone. The tankless never runs out of hot water.:)

Have had one here in Knoxville for the last 3 years and haven't had any trouble with clogging that I'm currently aware of. The only complaint I have is that you have to run the water an extra minute before the hot water comes out.

I just got one a few months ago. Do you have yours serviced every year? The guy who installed mine reccomeded it.

I think we might have had the plumber come back like once and make some slight temperature adjustments but other than that we've never had it serviced. Which one did you go with?
He recommended the Takagi T-K4-IN when we were looking and pulled the trigger. So far no issues.

If I remember correctly, I have a Rinnai.

I have a rinai, but it is propane. I would have done ng but too far out in the sticks for a line. However I love the thing. Does take a second to get warm water through the lines, but the sucker sips propane compared to my old one. I'm on track for about a 3 year payoff period where my savings on propane expenses will be greater than my differential cost installation.

Same for me on the gas. Couldn't deal with electric heat when we built and no NG available so we eent the LP route too. I now have a 50 gal water heater that can't keep up with demand from my aging family (teenagers). Also, we have a jacuzzi tub and it demolishes the water heater when used.

I can do about anything around the house so I'll probably attemot the install myself. The only thing that I'm concerned with is properly venting the exhaust. My current pipes are galvanized and they are calling for some kind of special stainless pipe. I don't see replacing the galvanized pipe as an issue but the big mushroom cap on the roof has me worried.

Watch out on the self-installation. Some brands will not warranty products that aren't put in by a licensed installer. The gas lines need to be sized properly, exhaust for inside models is very important, etc.

I always heard (well, at least this was true 5-6 years ago when I moved into my current house) that the gas heaters were more reliable and had less maintenance issues than the electric models. I had everyone from the Lowes and Home Depot salesmen to plumbers to sales men at the local electric/plumbing supplies tell me the same. But I'm wondering now if the technology for the electric heaters has caught up with the gas models...

I would think they would be less likely to clog since in a tank unit the water might sit there for hours or days whereas a tank less is a once through.

This is true wits the Rinnai systems unless something has changed.
