Tankless water heaters

Anyone done this successfully, and used their system for over year with no issues? I can go electric, because I upgraded electricals…
I this “I highly doubt you have enough electrical supply for five heaters unless you have industrial 3-phase coming in. Each (one-bath) heater can be 50A 220V. A full-house 6 gal/min tankless can be 150-200A 220V.” is smart advice that you should consider before.
Thank you.

Funny how before dishwashers had heaters they still cleaned dishes. Also how hand washing produces perfectly clean dishes and you’re nowhere near 140deg. Just another myth that has become the standard.
And why do you need to rinse in hot water? Why don’t dishwashers have a cold line for rinsing?
A whole house on-demand gas hot water heater is a possible solution here, but one for each bathroom is not a smart way to go.
Or you can green up your standard hot water heater by installing a pump to circulate hot water thru the hot water lines. That way, when you turn on the shower, you don’t have to wait for the hot water to come up. Thus saving water.
I get this question a lot: “My dishwasher isn’t cleaning the dishes well”
You have to hook up a hot water line into your dishwasher, feeding cold water into it, and expecting the internal heater to heat the water will not work.
Most dishwashers need to use the supplemental heater in the unit to get the water hot enough for proper cleaning. The detergents used in dishwashers require the water to be around 140 F for optimal cleaning.
Though of course if you research it, it’s ok to wash clothes in cold water. And the benefits of dish water hotter than from the tank are not in yet. So…the green thing to do is: don’t use heaters in these appliances.
if you go basement tankless, go for a gas fired unit
I don’t know if you can rely on the water heaters in the appliances to make the water hot enough. My dishwasher has a water-heating element too (I think they all do), but the installation instructions clearly stated that it had to be hooked up to a hot water line, and even specified what temperature the hot water flowing into it should be.
“What do you suggest for 3.5 bathrooms & 1 kitchen in terms of tankless?”
Start saving up.
I highly doubt you have enough electrical supply for five heaters unless you have industrial 3-phase coming in. Each (one-bath) heater can be 50A 220V. A full-house 6 gal/min tankless can be 150-200A 220V.
If you don’t go this route can I have half the amount you’ll save on electricity as compensation for this sage advice?
the idea of a point of use electric water heater in each bathroom is at best a terrible idea…if you want to go tankless you would be way better off putting a tankless gas water heater in the basement
Have you priced them out yet, including installation??? Stick with the old tank.
