Most California homeowners have learned how to deal with the status quo of hot water; once the hot water tank is empty, any showers, laundry or dishwashing must be put on hold until the tank fills up again. When you need hot water now but your hot water tank can’t seem to keep up with the demand, it can be frustrating.

If you have heard anything about tankless water heaters, you may already know that one solution to this problem lies in the on demand hot water they can provide. But the real question is, are tankless water heaters more efficient than conventional tank heaters?

The Problem with Tanked Water Heaters

The overwhelming majority of homeowners here in Dixon, Davis, and Vacaville use a 40 to 60 gallon hot water tank to cover their hot water needs. A traditional hot water tank works by filling up with cold water, then heating the water using a heating element or a gas burner (which takes time), and then the hot water is sent out to the shower, dishwasher, washing machine, or faucet. If that hot water is used up too quickly to be replaced in the tank, then your hot water remains at a lukewarm or even cold temperature until the tank has time to refill and reheat.

And what about the time you aren’t using that hot water, like during the workday or when you go on vacation? If that water in your tank goes unused, it is reheated continuously until you need it again. This costs you money each month in your electricity or gas bills and increases the wear and tear on your water heater by heating water you aren’t even using!

The On-Demand Water Heater: Going Tankless

So, are tankless water heaters efficient? The answer is: yes.

Tankless water heaters operate more efficiently by eliminating the hot water that goes to waste when you don’t need it. Instead of storing water that has already been heated, a tankless water heater speeds up the heating process and only heats up the water you need, on-demand. As soon as you turn on the hot water faucet, the electric heating element of gas burner turns on. Cold water is sent to a heat exchanger, where it is heated and sent where it is needed. The US Department of Energy estimates that an electric tankless water heater will save the average home $44 per year on hot water costs, and a gas-powered tankless water heater can save $104! But the energy savings aren’t the only reason to switch to a tankless water heater.

Saving Energy, Saving Space

Another attractive aspect of tankless water heaters is their small footprint. A 50-gallon hot water tank can take up a large chunk of a closet or basement, but tankless water heaters can be mounted on a wall, discreetly in a closet or hidden from view elsewhere.

Built to Last

At Greiner, we recommend that homeowners start looking at water heater replacement ten years after installation, or when there have been two or more required repairs in the last two years. Tankless water heaters are built to last much longer, with an expected lifespan of at least 20 years with regular maintenance.

Going Green? Go Tankless

Tankless water heaters save space in your home and save the headache of running out of hot water, but they also help reduce your impact on the environment. A tankless water heater that is at the end of its lifespan does not take up nearly as much space as a rusted hot water tank, and it reduces the carbon footprint of your home for longer than a traditional water heater!
