Perfect for any business looking to keep hot water running from its faucets, whole house electric tankless water heaters are designed to quickly and easily install into your existing water lines to ensure your water is at your preferred temperature. Each electric tankless water heater is made for either single or multiple points of use so you can provide hot water to one or multiple faucets. We also carry heaters with varying wattages so you can find one that works best for your needs.

As an alternative to bulky water heater tanks, our tankless water heaters provide hot water instantaneously, eliminating the risk of running out of hot water. They're also designed for everything from light- to heavy-duty use to work for a number of needs. Whether you need a unit to provide hot water to the whole building, or you just need a smaller point-of-use model, we've got what you're looking for.

Our selection of whole house electric tankless water heaters is supplied by popular brands so you can be sure you're getting a quality product for your purchase. Many of these heaters can mount directly on your wall to bridge your plumbing and your water fixtures, and their thin profiles ensure they won't become a hazard or disrupt workflow. With an electric tankless water heater for every kind of business, it's never been easier to keep running water at the best temperatures. For additional products to go with your electric tankless water heater, check out our wall mount faucets, deck mount faucets, and hand wash sinks.
