How does an electric on demand hot water heater work?

An electric on demand hot water heater, also known as a tankless water heater, works by heating the water directly as it flows through the unit.

The heated water then flows out of the unit and to your faucet, shower, or appliance.

Unlike traditional water heaters that store and continuously heat a large tank of water, on demand heaters only heat the water as it is needed. This makes them more energy-efficient and cost-effective, as they only use electricity or gas when hot water is being used.

The size of the unit and the flow rate determine how much hot water can be produced at once. Most units have a digital display that shows the temperature and can be adjusted to meet your specific needs.

Overall, electric on demand hot water heaters are a great choice for those looking to save money on their energy bills while still enjoying hot water on demand.

It is recommended to flush the unit annually to remove any mineral buildup that may decrease efficiency and cause damage. It is also important to have a professional inspect the unit periodically to identify any potential problems and make necessary repairs.

In addition to maintenance, proper usage can also extend the lifespan of the unit. Avoid running hot water simultaneously in multiple fixtures, as this can put unnecessary strain on the unit and decrease its efficiency.

Overall, with proper maintenance and usage, an electric on demand hot water heater can provide reliable and efficient hot water for many years.

If you are replacing an existing unit, the cost can be lower as the electrical and plumbing connections are already in place.
