Provide your household or business with reliable, on-demand hot water when you purchase a natural gas tankless hot water heater. We offer wholesale pricing, free shipping, and expert customer support on the best natural gas tankless water heaters on the market.

We’ve partnered with three of the top brands in the business: Bosch, State Water Heaters, and Triangle Tube. As a high-volume distributor for these respected manufacturers, we’re in a position to be able to pass along great prices, constantly updated product information, and innovations as they become available.

Our selection of tankless water heaters covers a wide range of BTU capacities and the types of applications they’re suited for.

For residences and small business applications, Bosch makes a dependable line of tankless water heaters with flow rates of 9 gallons per minute and from 160,000 BTUs to 199,000 BTUs. There are indoor models and outdoor versions for installations where indoor space is sparse.

These operate at 98% efficiency – formally known as AFUE (Annual Fuel Utilization Efficiency) - which means that only 2% of the heat produced is lost. Compare that to 85% efficiency for the best traditional hot water tanks and it’s easy to see the advantage of these tankless water heaters. You would save 13 cents out of every dollar over a traditional water tank.

Choose between vented units, which draw combustion air from inside the room, or direct vent units, which draw combustion air from the outside. With direct vent installations, it’s important to properly seal the exhaust portion of the vent pipe to prevent cold air from entering the house in windy conditions.

State Water Heaters produces gas water heaters capable of furnishing a 3.5-bathroom house (in southern climates) with an endless supply of hot water with multiple faucets open at once. Several of their models are condensing tankless water heaters, which means they extract heat from their own exhaust flow and cycle it back through to the water heating process. Their exhaust gases are therefore cooler than with non-condensing units and less energy is consumed.

The big kids on the block in this category are produced by Triangle Tube. These can be installed in very large homes, businesses, and industrial settings. They are marvels of production, sophistication, safety, and efficiency. Capable of not only producing massive amounts of hot water on demand, but monitoring flow rates, water pressure, and other factors. You can view the results on an LED screen or simply rely on the unit to keep up with everything automatically.

Helpful information is available on free, downloadable PDF files for each model. These files include vital data on technical specs, installation do’s and don'ts's, operation, and warranty terms. You can also call one of our well-trained customer service representatives for the latest updates on products, advice, and assistance with your order.
