re: Water heater - Tank vs Tankless?

Is this a water heater issue or distance from water heater to bathroom issue?
This is what was explained to me when we were trying to figure out location. Basically said the cold water you feel from a tankless is the hot water pushing whatever is in the system through. Once it pushes the cold through, you will have the hot water until you shutoff the valve.

we have to start a faucet near the wash room to make sure the washer is actually getting hot water.
Don't a lot washing machines have a heating element in them for when the water is first turned on, or am I thinking of dishwasher's only?

Would not do tankless if electric.
That said, I've posted this before, but from my experience with both tank and tankless, the ideal set up would be a tankless on the living quarters side of the house where the bathrooms are, and a small tank (20 gal?) on the utility side of the house for the kitchen and laundry room. Two difference styles of use with two different demand response characteristics.
If you do go with tankless, whether electric or gas, always go with the highest GPM possible. You will never get that GPM, but the more kw the more flow, the closer you'll get.

i had a navene at the house we just moved from.
i'm in nashville so we get colder winters here than La.
100% would do it again.
that thing was THE shite
seriously bad-arse but you gotta have a plumber run recirculation lines to get the full benefit.
that bitch will learn your daily habits and heat that water up in the morning so the second you hit the shower glorious hot water hits you instantly...and forever and ever amen.
3 or 4 of us could be cranking hot showers and it never skipped a beat.
i wonder how much my gas bill was due to the fact i didn't give a shite how long i stayed in the shower.
seriously, go navene.

I'm all electric. Priced a tank less (electric and propane.) Estimates started at $8,000. Considering the cost of installation and annual maintenance, there was no cost benefit.
I installed two electric 50 gallon tanks for under $2,500.

and those two can easily, and economically, be swapped out

We went tankless when replacing our old water heater earlier this year. The old tank had a great life from 1976-2024.
After the new tank was installed the water took F-O-R-E-V-E-R to get hot in my kitchen, which is the furthest from the water heater. Called my plumber and he suggested getting a higher gpm flow rate faucet and the problem was solved. Went from about 5 minutes of waiting to 30-45 seconds for it to get hot now.

I switched in 2017. No regrets. Replaced 2 tanks with one tankless. Only downside is loss of power which is rare for us these days.

Which has nothing to do with tank or tankless. Longer piping longer wait.

This is wrong. If you have a tank you are absolutely heating hot water. Do you think that 30 gallons is just instantly hot when you turn the faucet on?
If tanked it's a hot water heater. If tankless then it is a water heater (Because tankless the water is heated differently).

lol ok. When you go to Lowe’s or Home Depot what does it say? You’re playing semantics and trying to be cute. Whatever works for you I guess

It's not semantics. You literally said "you don't heat hot water." That is just flat out not true.

Point missed, again semantics. Carry on, smarts guy in the room

I am at least smart enough to understand the meaning of semantics, which apparently you do not.
You don't even know your own argument. If you would have said that saying "hot water heater" is redundant and therefore shouldn't be used, that would at least make sense.
But you literally said that it doesn't heat hot water. That's completely not true. It's not semantics.

When you install a water heater it’s filled with cooler water that his heated to the temp that is set on the thermostat. Once the water is heated the temp is then maintained to the temp that has been set bc obviously it will cool. When you run hot water the heater is drained of the hot water and filled with cool water that is again heated to the temperature set. If you want to call that heating hot water fine. It’s semantics now you can gfy. Have a merry Christmas smart guy

quote:The entire water tank is not drained unless you use all 30+ gallons (which should be rare). So you are indeed heating hot water to bring up the temperature. - make it even hotter

Less gpm with tankless?
Makes sense.
