Hello,

rate our house. One of his suggestions he made was to pull out my existing
Gas fired hot water tank and install a Tankless hot water heating system.
We don't have a family living here only my wife and I and we're both away
through the day working .....so the hot water demand is only morning and
evenings. It makes sense when he explains it. He says "why have a large tank
down there heating water 24/7 when your demand is about an hour a day?"

Actually because you have such low usage, it will take you all that
much longer to recoup the cost. I would think high usage would make a
better argument for spending the money on a tankless system by
replacing a perfectly good tank prematurely. At least I'd wait until
you HAVE to replace the current tank (at 11 year point depending on
your water corrosiveness). Then at least you can subtract a new tank
cost from the new tankless cost and start your recouping from there.
