What is a tankless water heater?
A tankless water heater, also known as an on-demand water heater, is a type of water heating system that heats water instantly as it is needed, unlike traditional tank-style water heaters that store hot water in a tank. Rheem electric tankless water heaters utilize electric heating elements to heat water as it flows through the unit. This eliminates the need for a bulky storage tank, saving space and potentially reducing energy consumption compared to tank-style water heaters. Tankless water heaters are particularly advantageous in applications where hot water demands fluctuate, as they provide a continuous supply of hot water on demand.
How does a Rheem electric tankless water heater work?
Rheem electric tankless water heaters operate on the principle of on-demand heating. When a hot water tap is turned on, cold water flows through the unit and activates a flow sensor. This triggers the heating elements to switch on, heating the water as it passes through. The heated water is then delivered to the tap, providing a continuous supply of hot water. The heating elements only activate when hot water is needed, reducing energy consumption compared to traditional tank-style water heaters that constantly heat water regardless of usage. Rheem’s electric tankless water heaters are designed to deliver a consistent flow of hot water, even during periods of high demand.
