Jim Connors: Hi! I am Jim Connors from Rheem Water Heating. Today, we will help you select the right electric tankless water heater for your home and discuss its operation and maintenance.
When it comes to selecting the right electric tankless water heater, the first question I ask is how many hot water appliances, showerheads and taps will it need to operate at the same time? There are online selection calculators to help you, but in most point-of-use applications like a sink or shower, you can choose one of the smallest models. They have a single heating element and run on 120 or 240 volts. As you add fixtures that operate simultaneously, you will need to move up to the larger models, whole home electric tankless water heaters have three or four heating elements and operate on 240 volts. Always consult an electrician before installing a tankless electric water heater to ensure adequate incoming power and amperage protection.
As soon as the electric tankless water heater is installed, turning on the hot water tap will activate the heating element and start the hot water flow. Be sure to look for model with an adjustable temperature control to help avoid scalding.
These controls are easy to use and it helps ensure that water is delivered at just the right temperature. Remember to consult your owner's manual or a certified plumber prior to operation. Electric tankless water heaters are designed for a very long service life. The water heater itself does not require any regular maintenance. Actual life expectancy will vary with water quality and the amount of use. But to ensure consistent water flow, you will want to remove scale and dirt that may build up at the aerator of the faucet or showerhead.
As you can see there are many benefits to electric tankless water heating. Its small size makes it easy to put hot water right where you needed. I hope you will consider an electric tankless water heater whenever virtually instant hot water and water conservation are important to you.
