The Basic Parts of Your Tankless Water Heater and Their Functions

Howard K.

If you need a plumber in San Fernando Valley, CA then get in touch with All City Plumbers. Tankless water heaters are one of our specializations, so if you have been needing water heater repair regularly, consider upgrading to a tankless unit. Tankless water heaters function in a manner that’s completely different than a traditional water heater. Rather than storing many gallons of water in a tank and keeping them hot 24/7, a tankless water heater heats the water only when there’s a demand for it. To determine the demand, a tankless water heater needs more electronic components than a traditional water heater. The following are the components of a tankless water heater and their respective functions:


  • Faucet: The faucet is the mechanism that activates the water so that it flows through the tankless.
  • Sensors: When water begins to flow through the sensors, the heating process begins.
  • Internal computer: This detects the temperature of the water and ignites the burners to heat the water.
  • Heat exchanger: Water circulates around the heat exchanger until it reaches the designated temperature. Once your tankless water heater in San Fernando Valley, CA , has heated the water to the designated temperature, it’s released to flow through the pipes to the faucet or showerhead.

If you have an older water heater, a tankless water heater replacement in San Fernando Valley, CA can be an excellent proactive solution. Don’t wait until your old water heater breaks and floods the basement, replace it today. If you have a storage-tank water heater, then a new tankless water heater installation in San Fernando Valley, CA, can make a dramatic difference in your monthly utility bill. California utilities are expensive, but a tankless unit can pay for itself within a few months, depending on your usage. When it comes to water heater services in San Fernando Valley, CA, rely on All City Plumbers. Our team can help you have the hot water you need on demand. We’re one of the best in the area, so we know you’ll be happy with our work.
