Beer and plmbr - you came up with this idea that if this product won't heat a whole house on 110 no one will buy it. You're trying to set this up as an all or nothing thing. Now, it's doubtful it will heat a whole house on 110. You're trying to set this up as an all or nothing thing - but you are "stuck" thinking there is only one way - and there can't be any other alternatives to what is already available. If the product will function better with fewer operational problems and is a lot easier to install then I'd be willing to bet there is room for this product on the shelves - and there will be plenty of folks, including plumbers who will want to install it.
One more thing - it's a little hard to believe that a "plumber" and manufacturing "expert" just sit here all day with nothing else to do but discuss the viability of a new product?
