How Do Tankless Water Heaters Work?

Water heaters are a vital part of everyday living. Washing machines, dishwashers, showers, and baths all depend on a water heater. Traditional water heaters lack the technology required for maximum efficiency. Not only does the tankless water heater outperform the conventional water heater; it offers many other benefits, as well. The cost and energy savings alone is well worth stepping up to this new technology.

Tankless water heaters provide maximum efficiency. Here's a brief look at how they work:

  • Tankless water heaters heat water on-demand instead of constantly heating an entire tank of water and storing it until it is ready to use.
  • When a hot water tap is turned on inside your home, cold water runs through the pipes and into the water heater's heat exchanger, which then heats the water using either an electric heating element or a gas burner. The hot water is then delivered to your tap.
  • When you turn off the hot water tap, a flow sensor within the water heater signals the control module to shut down the unit. This means you're only paying for hot water when you're using it.

Now that you understand how tankless water heaters work, here's why you should consider an upgrade!

Tankless Water Heaters Use Less Energy

Unlike tankless water heaters, the conventional water heater must maintain a tank full of hot water at all times. This can only be done by the heating element constantly cycling on and off throughout the day and night. This activity requires constant use of electricity and/or gas. If other appliances are used at the same time, hot water is difficult to regulate and quickly runs out. For instance, how many times while showering has the hot water run cold after a certain amount of minutes?

Tankless Water Heaters Offer More Temperature Control

Traditional water heaters are quickly overtaxed and cannot keep up with the demand. The tankless water heater uses modern technology that does away with the traditional hot water tank. A precise calculation system provides hot water on a case by case basis. For instance, when a hot water tap is opened the heaters unique flow turbine receives a signal to start the heating process. A technology advanced control board accurately measures the temperature of the incoming water and the desired water temperature.

Tankless Water Heaters are More Efficient 

Precision adjustments are made to the electric and gas flow to ensure maximum efficiency. This process continues until the appliance or tap is turned off. The tankless water heater just goes into the standby mode until needed again. The benefits of this system are obvious. Hot water no longer runs out since there is no fixed amount of water in a tank. Hot water is heated for as long as needed. Since the temperature is accurate and uniform, far less gas and electricity is required, this results in substantial savings of money and energy. The tankless water heater stays idle until the hot water is required.
