Oh, yeah, I know. $1000 labor which you’ll get back in 100 years or something, even assuming you don’t have to have your gas service upgraded. I’d never do it for the cost savings. If I ever did it, it would be for the “everlasting hot water” aspect, and it would have to be gas. No way am I going to pay triple. (Oh, forgot, triple minus 5%)
Still Thinking, my neighbor has a gas hot water tankless dealy. It works great and uses the standard 1/2” black pipe service. Nothing special. It’s for the whole house except for the bathroom sink, which I find odd. Luckily, as our town lost our gas service yesterday for about 12-16 hours. They had hot water at least, from that sink.
