I have seen several TVprograms that had segments concerning tankless waterheaters and I am definetly interested. I have checked several message and discussions on the net, but the more I confused I get. Everyone claims to have the best, but do they? I have checked on SETS,SEISCO,SUPERIOR,etc. I would really like to get the low down before I make a decision. Please e-mail me directly if you have any pertinent and concrete info.
