You may never know the value of your water heater until it stops working, especially during the colder months. Issues with water heaters range from minor and quick to fix to extensive and costly repairs and replacements. By understanding the significant parts of your water heater, you can extend its lifespan, improve its efficiency, and save money in the long run.

Allow Deer Valley Plumbing, the leading provider of water heater services in Maricopa County, to take you through the main parts of a tankless water heater.

1. Flow Sensor

The flow sensor detects water getting into the heater and alerts the control panel to start giving hot water.

2. Control Panel

The control panel is the most sophisticated among the tankless water heater parts and functions as the heart of the heater. It switches on the fan, which brings in outside air, opens the gas valve that allows the gas in, and ignites the burner.

3. Heat Exchanger

The heat exchanger stores small amounts of water, which the system uses to transmit heat from the burner. It seizures the heat from the flames and transmits it to the water moving through the tube. Issues related to the heating mechanism are common reasons for water heater repair in Surprise, AZ.

4. Mixing Valve

The mixing valve moderates the superheated water leaving the exchanger. It also helps in setting the maximum temperature to prevent scalding.

5. Temperature Sensor

The temperature sensor detects changes in water temperature. If it detects that the water falls short or exceeds the temperature your plumber set during installation, the panel adjusts the valves, gas valve, and mixing valve, flow-regulating valve, accordingly.

6. Vent

A sealed vent, which either runs through the outside walls or the roof, removes exhaust gases and takes combustion air to the gas burner. When doing water heater installation, venting must conform to the local and national codes and per the manufacturer’s directions.

7. Safety Features

Tankless water heaters have safety and control components that work together with the PC board to enhance protection. The ionization rods or flame sensors ensure the availability of flame, while an overheat sensor trips in case of overheating, shutting the system down. A freeze sensor and temperature limiter protect the heater from freezing, while a fan speed monitor ensures the fun functions properly. A pressure relief valve protects the heating system against excessive water pressure in the unit.Whether you need water heater replacement or repair, Deer Valley Plumbing can offer top-notch services.
