Does anyone have any knowledge of these hot water heaters? Cost to run vs tank type etc.? What brands are the best? TIA, Jim
Low flow point of use electric is good and quite manageable. House capable electric units will need at least 100A @ 220V to warm the higher flow used. They work at an escalating electronically controlled duty cycle as flow increases more and more above the amt needed to turn them on. Theyre great if you have the robust electric service where you need it.JimR said:Does anyone have any knowledge of these hot water heaters? Cost to run vs tank type etc.? What brands are the best?

That sounds like a 50A 220V circuit. If your feed water is very cold that power would give hot at about 1GPM. OK for a point of use faucet or a cool 2GPM trickle shower.JimR said:I do have the power and open breaker spaces to run two 50amps for the heater.

I have been told that the natural gas ones require a bigger supply pipe than the one that supplied the original 40 gallon heater.

First--I researched, but ended up going with the old tank heater... given the price of propane locally and the size unit I'd need, just would take a long time to get the return on it...
As mentioned earlier, the temperature of your water feed, and how many GPM you need will determine what set-up you need. In Maine our groundwater is so cold, most families need a dual set-up to keep pace with running a shower, doing laundry, dishes, etc. concurrently. A small household or single person would have different needs.
Most distributors will have a chart of groundwater temps for you to refer to.
I loved the idea of it, but just didn't see the payback, as the unit I bought went into a rental property. Good luck!
