Default Hot water heaters

Are tankless heaters worth the hype? My original tank unit is going after 8 years. I really don't want to spend any more than I have to unless it is really compelling to buy a tankless. Opinions anyone?

I have one, love it. Never ending hot water. Your shower experience will never be the same.

Hot water heaters
Why does hot water need heating?

Apologies...couldn't resist.

Be Well.

In the long run tankless are supposed to pay for themselves. They have been around a long time but have not caught on. I have never seen a tankless in a commercial building. Tanks have the benefit of giving you that many gallons of potable water if your power/water supply ever conks out.

Electric Tankless- will take additional electrical service beyond what an ordinary electric water heater uses- typical 40 amps at 220v. Natural gas/ propane you need venting (stack) Check the delivered amounts of water, and the temperature rise. Some are good for a shower, but play hell filling a tub. Advantage- they only use energy when you are using hot water. Also check if you are on a well to see life expectancy with well water (hardness)
What we have here is... failure- to communicate.

Water hardness is a problem for tankless heaters. Scale builds up inside and limits the life of the unit. Have your water tested for hardness.

They are worth all the hype depending on your water hardness. And maybe even then.

Couldn't one cycle the water through a water softener before running it through the 'on demand' water heaters? My sister has an 'on demand' water heater and she LOVES it. She is on septic and well but I believe she runs the water through a softener, first.

Looked at it several times. Lot of you get what you pay for with tankless water heaters. They are unlimited within the output capacity, i.e. cheapest one will provide for one tap at a time.

They avoid storage costs and wasteful reheating
generally more expensive to install
those with teenage daughters may want to reconsider Mine judged herself clean when the tank ran out of hot water.

If I were replacing my tank tomorrow, I'd take another really hard look at one.
