Hello,

I just had a person that rates houses for energy efficiency come and
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?"
Are there any disadvantages to this tankless system? Does anybody here
have one that would care to comment? Thanks.. Jim

Main disadvantage to me is the high cost to install them and replace them
when they go bad. especially if it is an old house with the tank already
installed.
If you are in an area that looses power, the small 5 KW class generator will
heat the water in a tank.
