Tankless Water Heaters

Based on “payback time” and energy savings, Consumer Reports says tankless water heaters are preferable to traditional storage-tank water heaters. Homeowners wince when they learn the upfront price difference, but tankless water heaters offer a good return on investment. And convenience? Priceless.


When it comes to electric tankless water heating systems, size matters. When your local plumbing professionals assess your water heating requirements, we look at your space requirements, household size, lifestyle, and hot water usage. A.O. Smith electric tankless water heaters deliver hot water when you need it, everywhere you need it, and for as long as you need it. Continuous, on-demand hot water.


Our ProLine® XE gas tankless water heaters boast higher efficiency ratings and A.O. Smith’s groundbreaking designs. These A.O. Smith tankless gas water heaters feature non-condensing and condensing technology, part of a new era in water heating. All condensing models are ENERGY STAR® rated, and ultra-low NOx options are available.

A.O. Smith Storage Tank Water Heaters for Easy Economy

Traditional water heaters are priced lower than tankless ones. Today’s storage tank water heaters save energy better than ever, and if the power goes out, you’ve still got hot water. Storage tanks heat your water before you need it.


A.O. Smith residential electric tank water heaters are built using commercial-grade components. This means they offer more durability and strength than other brands. They are quick and easy to install, and models come with warranties of 6-10 years.

Electric tank water heaters use one or two heating elements. Temperature sensors inside the tank signal the thermostat when it’s time to trip the heating elements and add heat to the stored water. You control and preset the temperature.


Natural and propane gas are cheaper alternatives to electricity. There are so many options for homeowners that A.O. Smith residential gas tank water heaters are available in 150 different models. You can choose a standard model or a higher-efficiency ENERGY STAR® qualified system.

A thermostat inside the tank regulates water heating cycles. The heating process creates exhaust gases, and those must be vented outside. Your Orange County, CA plumbing professional will help you choose the style of gas water heater that works best with your venting capabilities.
