So they now make those instant hot water heaters, that are just the little box that only heats water when it is needed and I'm not sure how else to explain them. They are just those little boxes that you have instead of a huge water heater and they are supposed to be very energy efficient. So my question is does your home have to be natural gas or propane to have one installed or can you have a 100% electricity house to have one installed? Also, are they that huge of an energy saver and are they pretty good or have they had many problems? If my question is confusing I am so sorry. My husband says to get one we would have to have natural gas or propane ran to the house and I want to know if that is true. Thanks for any and all help.
They come in either gas or electric. Here's a site with a little more information for you.
