I am shopping online for pool heater, and pretty much decided on the raypak 400k btu unit, until I read the internet sales policy. While they do not come right out and say your warranty will be void if you purchase online, they certainly hint at it and are openly opposed to an internet retail sale. They say "An internet purchase can affect your warranty." Check this out at http://www.raypak.com/Support/Internet Sales Policy. What do you folks think? Do I buy it anyway and hope for the best? Is this just a lame attempt to support their retail outlets or do they refuse to support products sold online? Should I worry about spending $2k and wind up with an unsupported product? When you get right down to it whats the difference, if I bought it from a local retailer, they would just order it online themselves and tack on quite a few dollars and have the unit delivered to my home. Are other manufacturers like this? Thanks for letting me rant as bit. (Yes, I am having a licensed plumber bring the gas line over and install the unit)
