Tankless Water Heater Services in Littleton, CO

The tankless water heater solves a problem traditional water heaters had for a long time: wasting energy and fuel. A tank water heater has to remain running all day long, but a tankless water heater can operate on demand. While high-efficiency tank water heaters are available today, we often recommend tankless water heaters for anyone looking to save money each month and reserve our natural resources.

When you want to upgrade to a tankless water heater in Littleton, CO, contact the team at Southwest Heating and Cooling. We also provide complete water heater services, including routine maintenance to keep your water heater in the best shape possible. We are a local contractor in business since 1973!

How Tankless Water Heaters Work

Unlike the tank water heater, a tankless unit only turns on when you need hot water. When you open up a hot water tap in your home, a computerized gas valve or electric heating element is activated to begin generating heat.

A heat exchanger within the system heats up, and water passes through it and to the tap you’ve turned on. Once you shut off the hot water, the computerized system detects this and immediately shuts down the water heater.

Tankless Water Heater Efficiency

The main benefit of a tankless water heater is energy efficiency. A tankless water heater does not have to keep running day in and day out. That means that energy is not lost throughout the day. (With tank water heaters, this is known as standby energy loss.)

Today, tankless water heaters are getting more and more efficient as the technology evolves. Since your water heater typically consumes about 17% of the total energy a household uses, that can translate into a huge savings!

Additional Tankless Unit Considerations

There are a few other reasons to choose a tankless water heater, but a major consideration is space. Tankless water heaters can be retrofitted into almost any home, and you don’t have to give up a closet or storage space to install it.

One drawback to tankless units, however, is that they take a while to get heat to the faucet—sometimes a couple of minutes. Plus, if you have multiple bathrooms with showers often in use at the same time, the tankless unit may malfunction. In this case, multiple tankless units are installed to have different units work for multiple bathrooms, but this can get costly. The investment may be worth it for your home—talk to your installer to find out!
