Best Tankless Heaters in Phoenix AZ

When our counter that they had made and installed developed a crack in it, they said it was because a crockpot we had used was excessive heat, so they wouldn't repair it. This was a standard crockpot, not a charcoal grill. Even when talking to one of the installers about the situation being a little ridiculous after all money the kitchen cost, he agreed. But of course there was nothing that could be done about it.
