On demand whole house tankless electric hot water heater
 

We have an all electric home with a standard 40 gallon electric hot water heater. I would like to change to a tankless unit which we had in NJ but We,had natural gas. It appears the technology has developed for use with electric. Has anyone done this and are you happy with the results.

Thanks for any help you can give

I've had one since 2004. I believe it was a good buy. In my case it takes 4 220 VAC Breakers in the distribution Panel.

I had one in my last home in So. Fla.
IMO while you will never run out of hot water, if it is just 2 people in the house this is not a problem. A tankless heater will not get the hot water to your bathroom any faster.
If you have a large family then a 30 or 40 gallon tank may not be sufficient.
