We're looking to purchase an electric tankless water heater because our standard (though fairly new) water heater just isn't cutting it for the whole house. We'd like one that will serve two bathrooms, sometimes running a shower in each at the same time. In addition to this, we live in an area with high water pressure so it really needs to have good output. Does anyone have one that they would recommend? I would love to shop around and speak to people, but I can't for the life of me imagine where I would find someone knowledgeable and well-versed, with items in stock, even in the Houston area.
