Dear Frederick: And everyone else who is tired of this spam thing. I sell waterheaters but it is not me posting these messages lately. I did post tips on waterheating, plumbing and electrical problems, followed by info on how to reach me to obtain products. I've learned that this is inappropriate and have stopped the practice. Someone else is using my name and misspelled e-mail address, to stir up bad feeling after I've already appologised. The other person isn't even giving advice, he's just causing a problem where a problem shouldn't exist. If anyone needs answers to waterheating problems: try www.cechot.com or www.seisco.net These are NOT my websites, they are there to assist you in making choices. Again, sorry about old spam. The real Brian Wood.
