Gas hot water heaters are efficient and effective. You now have the choice of traditional or tankless hot water systems. We would like to provide you with some information to help in the decision making process of your new water heater system.

Tankless water heaters are compact heating units that provide hot water as it is needed, and do not store hot water like traditional tank-type water heaters. When a hot water tap is turned on, water enters the tankless water heater. A sensor detects the water flow, and activates an electric or gas heating device, which quickly raises the water temperature to a preset level.

Rinnai Tankless Water Heaters

When water flow stops, the heating element shuts off. Thermostatically-controlled tankless water heaters vary their output temperature according to water flow rate and inlet water temperature.

Unlike traditional storage tank water heaters, tankless water heaters do not store a reservoir of hotwater. As a result, standby losses are reduced, which makes them an energy-efficient alternative to traditional water heating. When water flow is detected, they begin heating water, making them highly efficient and cost effective. When the demand for water ceases, they shut down and use virtually no energy.

There will always be hot water. Endless hot water - for bathing, cooking, dishes, laundry, and all the other countless ways hot water enriches our lives. Tankless water heaters consume a fraction of the space consumed by a tank heater. They can be mounted inside or outside.

Tankless water heating saves you money and time!

Enjoy up to 40% energy savings, endless hot water, and significant space savings.

Because tankless heaters do not store water, they are less subject to corrosion than tank-type heaters. As a result, their expected equipment life is possibly longer - more than 20 years, compared with 10 - 15 years for traditional heaters. Also, because they are not heating 40 - 50 gallons of water 24 hours a day, tankless water heaters are less susceptible to leakage than tank-type water heaters.

Designed for Efficiency

Rinnai’s tankless technology features copper heat exchangers to provide maximum efficiency and uses up to 40 percent less energy than a traditional tank.

Save Energy

By operating only when hot water is needed, and no storage tank to heat and reheat water, our tankless technology helps save on energy and utility costs. The use of an electronic ignition means no standing pilot light that constantly uses energy.

A Smart Investment

Increase your home’s value with premium technology, increased energy efficiency, an improved Home Energy Rating System (HERS) Index Score and optimized LEED certification. Available energy efficiency rebates and tax credits offer the opportunity to help make your purchases more affordable.

Replace Parts, Not Systems

Every part of a Rinnai Tankless Water Heater is replaceable. Components can be easily exchanged, if needed, versus replacing the entire system.
