How to Use Tankless Hot Water Heaters

Using your tankless water heater is as easy as turning on your faucet. Whether you have chosen a gas or electric water heater, using them is the same. Once the tankless water heater is properly installed, you simply turn on the hot water.

Difficulty: Easy

Instructions

1. Ensure that your home or business has and appropriate energy source for the tankless water heater. You may need to upgrade your existing energy source to accommodate a tankless water heater.

2. Hire a professional to install your electric or gas tankless water heater. Having a professional install these systems is important so that the proper energy source is obtained and the proper ventilation is installed.

3. Adjust the thermostat to a temperature that works best for your home. Your installer can do this for you and can show you how to change the temperature on your specific unit. The thermostat adjusts to maintain a constant water temperature, despite the amount or change of water flow.

4. Open the hot water tap, usually by turning on the hot water at a faucet, to allow the water to flow through the tankless water heater. The heating elements quickly heat the water running through the unit.

5. Turn off the faucet to shut down the tankless water heater. When the water stops flowing through the unit, it automatically turns off.

Tips & Warnings

• When cold water is turned on at a faucet, it does not trigger the heating unit, thereby being much more efficient than a standard hot water heater.
