Tankless Water Heaters Vallejo / Bay Area

Happy A-1 Guaranteed team member showcasing work

Tankless water heaters are the “next big thing” across the Bay Area, and for good reason. Heating water in our homes for bathing, cooking and other uses accounts for about 30% of a home’s total energy usage, so it’s easy to see why people are very interested in conserving as much of that energy as possible. If you have a home with multiple people or you have a large tub to fill, this product is for you!

Money-Saving and Eco-Friendly Operation

One of the biggest reasons people are attracted to the idea of installing a tankless water heater in their homes is the fact that heated water will then be available “on demand”. Hot water is not stored in a tank and kept warm continuously by a gas flame, as it is with standard gas tank units. In contrast, with a tankless unit, water isn’t heated until the need for it arises. These tankless units most commonly operate on natural gas or propane. Less energy is consumed because they eliminate the costs associated with keeping 40+ gallons of hot water on reserve on a consistent basis.

In addition, monthly savings from switching to an energy-efficient tankless unit can be up to 40% off utility bills, making these units an investment that pays for itself over time. Efficiency ratings are up to 30% more efficient vs. a traditional tank heater, too.

Convenient Comfort

Since water isn’t stored in a tank, but instead is heated on demand, tankless water heaters provide a continuous supply of hot water. No more running out of the shower from cold water, or waiting hours to replenish a household’s supply of heated water in the tank after laundry has been done. Families no longer have to time their showers or schedule everyone according to the availability of hot water – it’s always available with a tankless unit. These units also take up much less space than the conventional tank units do, and can also be mounted on a wall or even installed outdoors.

Clean and Safe Water Delivery

Standard tank units require that water be stored in them and wait for demand before they are used. As such, tanks can often accumulate rust, scale and calcium, settling at the bottom of the tanks and infiltrating the water. With tankless water heaters (upon regular flushing), there is no health risk from using water that has been sitting in any type of contaminated tank, and there is also no worry of a tankless heater rusting through on the bottom, spilling 40 or more gallons of water all over your home!

In addition, tankless water heater models are equipped with safety features that prevent overly hot water from reaching faucets in the home, greatly reducing the risk of scalding and burns.
