on demand hot water

[Dave M]

I been thinking about changing to a hot water on demand system and was wonderig if anybody has this kind of system. Read Consumer Reports and they mentioned that it won't be any less cost, pipes clogging up,waiting for the hot water,etc. Is it worth to having this type of system. I drain the pipes in the camp at the end of the season. Can this be done with the on demand equipment.
