Have you had yours replaced? Did you go tankless? Pros/cons besides the obvious advertised selling points? I need to make a fast decision and I need assorted people to ignore.

We went tankless for some extra storage space and I thought it would be neat because I'm a retarded technophile. The unit itself and installation was expensive, occasionally during a shower the water goes cold for a moment and really pisses me off and maintenance certainly hasn't been cheap either.

Hmm, so it doesn't sounds like it's probably saving a ton of money on the efficiency aspect. I don't really care about the storage space since our basement is fieldstone and I'm not hanging out down there. Thanks for the info - really helpful.

Too new. Saves space. Expensive. Permanent hot water is useful only occasionally. Requires disassembly and cleaning on a regular basis to clear out mineral deposits.

Any energy/fuel savings are eaten up in the maintenance and initial cost.

Only do it if you want the space otherwise just get an appropriately sized standard water heater.

Yeah, I haven't really researched it but the minimal reading I've done suggests that it takes 12-15 years for the system to "pay for itself" over a conventional tank heater.

My hot water heater needs replacing but so far I've been doing this thing called "Ignoring it until it's a catastrophe". It's worked so far so I have no reason to believe it won't continue to work forever. Smiley: thumbsup

Also, I suppose "hot water heater" is sort of redundant.

But we want hotter water

I researched them quite a bit. I really wanted to try one, but after a lot of thought with the cost of natural gas vs electricity, and the cost of a tankless vs tank, decided not to. The amount of savings is negligible (imo) and takes so long to happen.

My current hot water heater is a tank style, electric. And is about 20 years old. It needs to be replaced. (2600 square foot house, 2 baths, designed for a family of 4, more than enough hot water for myself and my brother).

I have a propane tank heater in my basement that was set to be installed, but 2 years ago we switched to natural gas, and hot water heaters are not usually convertible (unlike furnaces and stoves) so I have to buy a new one. And try to sell my old (new) unused propane heater.

I looked at tankless electric. The power requirements are outrageous. One similar one to the usage of my current one I saw was 3 - 40A breakers. I have a modern 200A panel and that would be a difficult upgrade. Electric on demand would be foolish I think. I have one in a factory I maintain and it's a pain in the ***. Would want to go gas if at all.

With natural gas being so cheap, I am just going to switch to a tank heater, natural gas, and call it done. With an on demand, you still have to wait for your hot water, unless you have a point of use on demand. Because the period of cold (or not warm) water out of your faucets comes from the idle water in the lines between your heater and your point of use. And you hear a lot from end users about occasional cold intervals. While I haven't used one in my house, I have used the one industrial on demand in a factory, and it would periodically fail to heat the flowing water correctly and deliver intervals of cold water. Seemed very flow-sensitive. Too much or too little and it wouldn't heat the water right. Maintenance on your standard tank heater is not much other than the occasional cleaning (depending on your water quality) and possibly having to replace a T&P relief valve and that anode rod (I've never actually changed the rod in mine). And with gas instead of electric, I think you don't get as much calcium/lime buildup because you don't have the super hot element in the water collecting the scale.

So, I'm not going to go tankless when I replace my electric with a gas. Centralized tankless just doesn't seem to solve any issues with the tank system. And point of use tankless... maybe, but I'm not interested in installing them in each sink and shower. One tank under my basement stairwell is fine for me.


Is this mansplaining?

Replaced ours a couple of months ago. It was leaking, badly. Water bill is now half what it used to be.

Yeah. I thought the same thing. Until the catastrophe happened. And, of course, it happened on Thanksgiving (why do all my water related problems happen on Thanksgiving?). Which meant waiting 4 days to get someone out to look at it, then to discover that the specific type I needed wasn't available and had to be ordered, which meant another handful of days. Cold showers in late November sucks in San Diego. I can't imagine dealing with that in Chicago. If it actually does need replacing, I'd seriously recommend just doing it now. It'll cost less money than having to do it all emergency like, and you wont have a gap time with no hot water. Not to mention, you wont have a flood wherever your water heater is. Mine's in a little shed attached to the side of the building, so it just watered some grass with hot water. If yours is in a garage or basement, that's a lot more of a problem.

They will eventually burst and leak all over the place. Just a matter of time.

As to the OP question: I've also talked to people who've used them about tankless water heaters, and I'm not sure how great an idea it is. As several people have noted, the cost savings per gallon of heated water in a home system isn't really that great, so it'll take a long time to pay for itself (and may actually never do so depending on the cost of the model and installation you started with, and whether it's electric vs gas). The issue of inconsistent water temperature is a real problem. Not like a disaster, but it will annoy you. And the heating process is not "instant" by any means. So it'll take a bit longer after turning on the hot water before you actually get hot water (same time pushing room temp water through the lines plus the time to heat the exchanger in the unit before actual hot water comes to your faucet). The only actual benefit is that you don't technically "run out" of hot water. But unless you find yourself consistently running out of hot water due to high usage that exceeds the tank's capacity, it's not worth it.

We've tried them out when replacing hot water tanks in some of our smaller hotels. Don't like them one bit. I'm sure commercial and residential are the same...

No but I'm thinking that maybe burning the house down will be the most efficient way to heat the water. I'll get back to you all on my success.

*note to fbi and/or insurance companies, I have no actual intention of burning down my house.

Seriously though, thanks for all the feedback. I was already kinda on the anti-tankless side of the fence but I've typically been in favor of any sort of "efficiency" type upgrade whenever the occasion presents itself. So, the user-experience is really helpful.

I'm assuming by the frowny face you don't mean you're gay and spend Valentine's day being someone's power bottom.

I'm also guessing you didn't get your testicles blown off in 'Nam. Because that would deserve more than a frowny face.

I also live in a condo. I think the upstairs units have water heaters inside the units themselves (which actually bothers me a bit given the issues I've had). The downstairs heaters are in little shed thingies attached to the wall of the unit itself. In my case, right outside the mater bedroom. There is a noticeable difference in terms of default water temperature based on time of year, but it's not too bad (I have to turn my shower knob about a quarter turn more hot to get the same temp water). Cause, yeah, mild weather.

While I like having a condo for a number of reasons (far less maintenance and yard work, don't have to deal with trash pickup days, access to facilities that are included in the HOA payment, nice landscaping that I don't have to deal with personally, etc), one of the major negatives has been the stupid piping they put into them when they were built. I've had three water leak problems, and each one as a pain in the ****.

I'd expect that a cold water shower in November would be roughly equivalent to one in April or September because, you know, central climate controls. I suppose in July you could turn off the AC and pretend that taking a cold shower was refreshing.

Where I live, if you turn off the AC in July, a cold shower is likely the only thing between you and a horrible, desiccated death.

Hot water heater is gas. If I want a cold shower I just tell my wife to hug the water heater for a moment.
