When my house was built in the 70's, they stuck the electric hot water tank as well as the solar tank in the unfinished bathroom on the lower level. We would like to get rid of that situation and go with a tankless system, which would mean not running out of hot water after a couple people shower. I had always been set on a propane system. Someone mentioned last week about having an electric one. This would allow a ventless sytem as well, which would work for me. And so now I'm torn on which way to go. Besides Pennsylvania deregulating the electric in the state, and by most estimates electric rates will go up 50% in the next year or so, are there other pro or con issues with electric tankless systems? If you had to choose, propane or electric, which would you go with? Thank you.
