Tankless Water Heater

[Crystallas]

Cons, price. Assuming you don't buy the cheapest crap out there.

I have 3, one for kitchen, one for bathroom, and one for flooring(radiant heating). Two are natural gas, one is electric. Have had them for 9 years now, and I just did maintenance on all 3 last year for the first time since installing. All I did was run two bottles of CLR (between all 3) through it to descale mineral buildup. I would hope the ones you can buy today are even better. You save time and water, plus they use less gas/electricity than a traditional whole-house tank heater.

My plumber is recommending 1 for the whole house, not individual ones

I hear 2 complaints


1..The water temp is inconsistent

2..It wont fire up if the faucet is on a slow flow

I have 3, because I have two separate water lines, and radiant flooring. One whole house one is better if you have one source. You can also use a buffer tank for the instant heaters, technically not tankless, but get the best of both worlds if you think you're going to have some problems with low flow.

Could always use a plastic buffer tank...It wont rust out

If it's built correctly, none of these will rust. Whatever you decide to go with, it's going to be an upgrade over the prior heater. I'm just happy I went tankless myself. The spot where the tank used to be, is now a shelf. But tankless use less space, not NO space, so I ate up some space elsewhere(just not as much).

I didn't know a natural gas tankless heater with a back-up tank was an option. If so, I may have gone for it. We live in a condo, so options were limited to electric tankless or nothing.

The heater you have now wont last forever. By that time, who knows what you'll go with. Maybe direct fit, atomizing faucets will be on the market.

They say 8-10 years for a heater..Mine are goin on 14..Theyre not leaking. But as long as I am doing the remodel, I figured I should change em before I put new carpet down and it gets soaked

I am well aware of that since our gas one burst 2 years after we bought our place. The issue at the time was how to make the replacement fit with the building system, and I got discouraged from a tankless in an 8-unit system, and as I said, I was a first-time home-biyer and admit I probably got ripped off into buying another tank.*

*Troll sidebar

I got the condo association to pay for a bulding-wide replacement of all heaters because if our water tank burst, who's to say when theirs wouldn't soon since they were all installed at the same time? We all paid through associations but at the same time, everyone's heaters were 12 years old, and we have no super.

I have both in my house, the regular gas hot water heater 70 gallon feeds downstairs and I have a tankless for the upstairs. Love my tankless, would have put it in both places but we loose power and the Mrs loves having the back up 70 gallons of hot water, what are you going to do...

Pro's take up a lot less space, cheap cheap cheap on gas, not storing heated water for long periods of time (eye's the Mrs. NCChiFan and she doesn't even know why), will pay for itself in the long haul. Not had a single glitch in 5 years. Endless hot water.

No real Con's.

NC...Do me a favor..Open one of the faucets connected to the tankless so that they would have a slow flow....See if the tankless fires up..TY

Oh yea, don't have to, know that answer already, as soon as the Rinnai senses water flow, even a trickle it kicks on.

TY Sir!!

I've heard that they're difficult to install, and no one appreciates it.

I guess it's a tankless job, but somebody's gotta do it.

Glad you got the info you needed Bearsbud! Have a nice day!

How much did ya'lls bill go down when you switched over to a tankless. I am also considering one.

My plumber loves his tankless, but said his bill went up
