Snorting his way across the USA
Tankless concern me about legionella (I’ve seen too many of them installed at point of use instead of a proper hot water system with tempering valves in commercial settings). But I would like to have a mini “boiling water” tanked system under my kitchen sink. When I was a kid my grandparents had a boiling water tap in the kitchen (one of my uncles had built it as a science fair project in the 1960’s). It was usefull as all get out, boiling potatoes? Instantly boiling hot water in the pan, put it on the stove and it boiling, making coffee? Put the grounds in and fill the dripper, want a boiled egg, just put it in a pan and fill it, when it was cool enough to take out it was done, that thing was awsome but could never be marketed because of liability issues.
I don't know which kettle you have, but the term is "induction". And, yes, they can be very fast!The bride bought an 'instant hot' kettle which I believe is an invection process. However it works, it works great. Heats a quart of water to boiling in about 90 seconds. Almost as good as an insta-hot tap without the plumbing and electric install.
Wait, what? Most people who have even heard of legionnaires disease go with tankless to lower risk.Tankless concern me about legionella

Why?Have tankless in my condo,not a big fan.
Probably because a big fan is a terrible way to try to heat water.Why?
Both transfer energy, they don't cause heat.Invection, induction, both cause heat, right?
Too much election, not enough flying.
Ours is running about 11 years strong. Descale once a year is super easy. I see no reason to go back.I love my Rinnai tankless. Installed it about 3 years to replace an 80-gallon electric. I out the LP tankless in the garage and gained a whole new closet in the house.
Love the unending hot water and no energy use when we aren’t home. As a bonus, my generator can easily provide the electricity needed for the tankless.
I spend about an hour once a year descaling. Easy peasey.
I would never go back.
Notice commercial point of use in lue of proper hot water system with mixing valve in my post, think bathroom touch less sinks (the ones without handles, just a sensor to turn on warm water when your hands are under it. Proper way is a hot water line hot enough to deal with it then temper it with cold water through a mixing valve. On demand set to “warm” with one line feeding it is a lot cheaper but a perfect breading ground if there are any issues with the chlorination or anything in the system that uses up the free chlorine before it reaches it.Wait, what?

Ooh, I am interested in this too. Same issue, and my current water heater is pretty long in the toothI have contemplated putting a small tankless under the kitchen sink. As it is today, the kitchen sink + dishwasher are the farthest point from the tank water heater in the attic (yeah, I know.. it was there when we bought the house and I haven't found a suitable way to move it down to ground level without replumbing the whole dang house), so any time you just need some hot water to wash your hands or rinse something out, it takes a while to get hot water down. It would be nice to have hot water on-demand at that spot. Anybody done this? It might also help me justify running gas to the kitchen so I can get rid of that GDMFPOS (see other 'frugal mechanic' thread for translation) electric range.
That's odd, most showers use more water than a sink faucet. I very rarely shower at home, so I haven't been able to test it out yet. It is a Navien unit.I had one in the shop for radiant floor heating. Worked great!
Now I have two for domestic hot water in the house. The ONLY thing I don't like about it is that they have a minimum flow. So if you want a low flow of hot water, you won't get any at all (checked with Navien and they confirmed). That's a problem for me in Florida during the summer months. After working outside I want a barely lukewarm shower to cool off. Except all I get is cold water. So I have to turn on the hot water in sink faucet to generate enough demand while I take a shower.
Bought one of these a month ago. The only part of the unit that gets hot is the glass. The base of the pot and the stand remain cool. The heating system is completely encased and insulated in the pot's base. It's FAST!...But I would like to have a mini “boiling water” tanked system under my kitchen sink.

Got it. So not a problem with tankless, but with installation. If you mix your warm water near the tank heater the same problem would be there, right? And if I ran hot water from the tankless to the sink then I'd be fine?Notice commercial point of use in lue of proper hot water system with mixing valve in my post, think bathroom touch less sinks (the ones without handles, just a sensor to turn on warm water when your hands are under it.

In the summer, to cool off, I take a shower with almost no hot water. Just enough to take the chill off. IIRC, our Navion requires 1GPM. So to get the demand over that, we turn on the sink faucet. Had I known, I would have added a faucet to the shower.That's odd, most showers use more water than a sink faucet. I very rarely shower at home, so I haven't been able to test it out yet.

They make mini electric tanked heaters for exactly this. A tank would require a lot less demand on your electrical system. On demand electrics can really draw a lot of amps.Don't need much, just a kitchen and bathroom sink for hand washing, etc
LP is an option if NG service isn't feasible.Don't need much, just a kitchen and bathroom sink for hand washing, etc... no bathing, no laundry. the place used to have natural gas. It's still under the road but the service drop has been abandoned, so gas isn't practical
do any of you have electric versions?
We just recently bought an office building for my wife. I little old bungalow house that had been at some point converted to an office. It has a small tank heater in the crawl space... an open wet dirt crawl space
looks like a homeowner's special installation and is old...but still works
So I've had in mind that after the dust settles from the higher priority remodeling, I'll be considering a small tankless.

no kidding. I think the water heater in my folks house is approaching 70 years hold and still going strong.So how do you like it? Our town's water is hard and it eats the tanks. Tanks no longer have that glass lining they used to have to prevent corrosion of the steel tank walls. They're just finished with some sort of hi-temp paint or something.
Nowadays the technology is refined to the point that the engineers can calculate exactly how thick to make the coating so they last for the duration of the warranty and no longer.So how do you like it?
