Heat Water Only When You Need It!

Tankless water heating is the wave of the future – available to you today. You’ll enjoy up to 40% energy savings, endless hot water, and significant space savings – plus a typical life span of 20 years or more in residential applications. And this “green” technology produces less CO2 and NOX than

conventional gas or electric tank water heaters.

You see, Rinnai tankless water heaters use natural gas or propane gas to heat water only when needed. When water flow is detected, the Rinnai begins heating water as it passes through its copper heat exchanger. The design of the unit allows it to capture up to 84% of the heat energy, making it highly efficient and cost effective.

When the demand for water ceases, the tankless unit shuts downand uses no energy – a revolutionary advantage over inefficient tank-style heaters. More efficient when it’s on, and off when it’s off, the Rinnai tankless water heater is the ultimate choice in today’s world of high energy costs and environmental preservation.

Additionally, your Rinnai is supported by the most extensive group of professionals in the business. Our nationwide network of more than 80,000 registered dealers and factory-trained installers ensures a trouble-free installation and reliable after-the-sale support.

Enjoy Endless Hot Water

Tankless water heating is one of the few energy-saving technologies that actually improves the quality of your life. You’ll delight in endless hot water – for bathing, cooking, dishes, laundry, and all the other countless ways hot water enriches your life. Plus, our digital controllers give you precise control of the output water temperature for the ultimate in comfort and safety.

Save Space

Traditional tank water heaters can take up to 16 square feet of valuable floor space. But your Rinnai unit – only about the size of a carry-on suitcase – can be installed on virtually any wall inside or outside of your home or building. The compact design affords you almost limitless installation options, so you can strategically locate the unit for maximum performance and energy efficiency.
