Oct 22, 2023 | Chronomite

When it comes to tankless water heaters, the Chronomite SR 20L/120 stands out for its exceptional performance and efficiency.

In this comprehensive review, we will delve into the key features, technical specifications, installation process, performance, maintenance, troubleshooting, and how it compares to other models.

Why are tankless water heaters becoming so popular?

Before we dive into the details, let’s take a moment to understand why tankless water heaters have become increasingly popular in recent years.

Cost savings & energy efficiency

Traditional water heaters store and heat a large volume of water, which can lead to energy wastage. They contain storage tanks, which often suffer from standby heat loss, where energy is wasted as the water sits in the tank waiting to be used. However, with the tankless design of tankless water heaters like the Chronomite SR 20L/120, there is no standby heat loss, resulting in significant energy savings and lower utility bills.

Shorter wait times for hot water

Traditional water heaters often have long wait times for hot water. Tankless water heaters, on the other hand, provide hot water on demand.

No longer will you have to wait for the water to heat up or worry about running out of hot water during a shower. With a tankless water heater, you can enjoy a continuous supply of hot water, ensuring a comfortable and enjoyable experience every time.

Ease of Installation

Traditional water heaters are much more complicated and costly to install, not to mention take up significant space in your house or business.

With a tankless water heater like the Chronomite SR 20L/120, its compact and sleek design makes it easy to install in any space in both residential and commercial spaces.

Installation Process of the Chronomite SR 20L 120

Installing the Chronomite SR 20L/120 is a straightforward process that can be completed by both DIY enthusiasts and professional plumbers. Before you begin, ensure you have the necessary tools:

Tools Required for Installation

  • Electrical Junction Supply Box
  •  Electrical Supply Conduit
  • Electrical Supply Wire
  • Dual Outlet Angle Stop
  • 3/8” Flex Hose or 3/8” O.D. Tubing (2)
  • Carpenters Level
  • Flat Head Screwdriver
  • Phillips Head Screwdriver

Step-by-Step Installation Guide

  1. Starting the installation process, it is crucial to ensure safety by turning off the breaker and disconnecting the electrical supply to the area. Additionally, shut off the water supply to the fixture. Double-check that everything has been properly turned off before proceeding further.
  2. To access the electrical connections, unscrew and remove the front faceplate of the Chronomite unit. Keep the screws in a safe place. This will allow you to reach the electrical connections within the unit.
  3. Choose a suitable location for mounting the Chronomite unit. Use heavy-duty metal screws to securely mount it, ensuring that the existing electrical wires are pulled through the hole provided at the back of the heater unit. Each corner of the unit has a mounting bracket to assist in the installation process.
  4. Connect the electrical supply wires to the corresponding electrical connections on the Chronomite unit. Make sure to tighten all connections securely to ensure proper functioning.
  5. After connecting the electrical supply, close the front faceplate of the unit and securely screw it closed.
  6. Connect the Cold Water supply line from the water source to the bottom Cold/Hot inlet compression fitting opening on the Chronomite unit. It is important to note that Chronomite Tankless Water Heaters require only one cold water intake, eliminating the need for additional lines.
  7. Next, connect the Hot Water supply line from the top Cold/Hot inlet compression fitting opening on the Chronomite unit to the sink.
  8. Once the water supply lines are connected, reopen the water supply line to the unit and turn on the sink for 2 to 3 minutes. This will help purge any air from the lines. Keep in mind that the water will not run at the desired temperature until the breaker is turned back on in the next step.
  9. Screw the supplied Flow Control Valve onto your faucet or fixture head.
  10. After purging the air from the lines, turn on the breaker to supply power to the Chronomite unit. Now, you can enjoy the benefits of your new Chronomite Tankless Electric Water Heater at the desired temperature.

Maintenance and Troubleshooting

To ensure optimal performance and longevity of the Chronomite SR 20L/120, regular maintenance is essential. Follow these routine maintenance and operational tips:

  • The Flow Switch is designed to activate when the flow rate reaches 0.35 gallons per minute (GPM) 1.3 LPM and deactivate at 0.30 GPM (GPM) 1.1 LPM.
  • If you happen to increase the flow rate of the water beyond the capacity of the heater, you may notice a decrease in the water temperature. However, you can always mix cold water with the hot water, just like you would with a conventional system, by using a two-handle faucet. To ensure the best results, make sure to select the appropriate Flow Control based on your desired water temperature.
  • Keep in mind that it is not recommended to operate the Chronomite SR 20L/120 water heater at a hot water flow rate of 0.30 GPM 1.3 LPM. This is the threshold at which the unit will deactivate.
  • To prevent any potential issues, it is important to periodically inspect the supply lines, connections, and the heater itself for any signs of moisture, corrosion, or other preventable problems. It is recommended to perform these inspections at least four times a year.
  • Before shutting off the water valves for servicing or winterization purposes, always remember to disconnect the power from the unit first. This precautionary step ensures safety and prevents any potential electrical hazards.
  • Lastly, it is important to note that the Chronomite SR 20L/120 water heater is designed solely for heating water and does not provide any means of cooling. Therefore, it is essential to only connect the cold water feed to the inlet of the unit.

Common Issues and Solutions

In the event of any issues, the following common problems and solutions can help troubleshoot:

  1. If the water temperature fluctuates, check the water flow rate. Adjusting the flow can stabilize the temperature.
  2. If there is no hot water, ensure that the power supply is connected, and the temperature settings are adjusted correctly.
  3. If leakage occurs, inspect the water connections and tighten them as needed. Replace any faulty components if necessary.
