What is an electric on demand hot water heater, and how does it work?
An electric on demand hot water heater, also known as a tankless water heater, is a type of water heating system that heats water on demand as it flows through the unit. Unlike traditional water heaters that store hot water in a tank, tankless water heaters heat water only when needed, providing a continuous supply of hot water without the need for a storage tank.
The unit operates by using electric heating elements or gas burners to heat the water as it passes through the heat exchanger. As the water flows through the unit, sensors detect the flow and activate the heating elements or burners, providing hot water on demand. When the water stops flowing, the heating elements or burners shut off, conserving energy.
Overall, electric on demand hot water heaters are an efficient and cost-effective way to provide hot water in homes and businesses, offering an endless supply of hot water without the need for a storage tank.
What size electric on demand hot water heater is needed for different home sizes and usage needs?
