How Do Tankless Water Heaters Work?

Black Forest Plumbing Tank less Water Heaters


If you need to replace your current water heater, consider installing a tankless water heater. It can save you money and deliver an endless supply of hot water to your showers, sinks and appliances. Here’s how tankless water heaters work and how you can benefit from one in your home.

Tankless water heaters vs hot water tanks Traditional hot water tanks have a large tank that holds a supply of hot water for when you need it. On the other hand, tankless water heaters don’t require a storage reservoir. Instead, elements or burners heat the water directly as it flows through the unit. There are two types of tankless water heaters: electric and gas. Electric units use an element to heat the water as it flows past, while gas units heat the water using a burner. How your home is configured may determine which type of heater you can buy. Benefits of using a tankless water heater There are several advantages to choosing a tankless water heater, including:

  • Convenience. Tankless water heaters are compact and don’t take up much space. They can fit under stairwells and inside bathroom vanities. Additionally, tankless heaters are perfect for apartments and condos, vacation homes and outdoor showers. Some models also have digital display thermostats and remote controls.

  • Continuous supply. You don’t have to worry about running out of hot water with a tankless water heater. The design ensures an endless flow of water for long hot showers or a relaxing soak in the tub.

  • Energy efficiency. Tankless water heaters are more efficient than other types of water heaters and can reduce your energy bills by 25 to 40 percent. Moreover, the life expectancy of a tankless heater is 20 years, which is at least five years longer than traditional water heaters.

What to consider when choosing a tankless water heater Tankless water heaters measure water in gallons per minute (GPM). Therefore, you must determine your water usage before buying one. If your heater supplies a shower, dishwasher and washing machine simultaneously, you should get a unit with a high GPM flow. Moreover, you need to consider the temperature of the water that enters your home. The colder the incoming water, the more power your unit will need to get water to the right temperature. Finally, consider the electricity requirements of your heater. For example, many units require special wiring, a 240-volt connection and four dedicated breakers.
