Tankless Hot Water Heater: Definition And Benefits

24 / 05 / 2021

What is a tankless hot water heater? Sometimes referred to as instantaneous water heaters, these devices deliver hot water only when its needed. In contrast, conventional water heaters heat up water stored in a tank for use later, regardless of your actual hot water requirements. Conventional water heaters use electricity or gas to heat and store water until the taps are turned on. As hot water is used, the tank is refilled with cold water and the heating process resumes. The effects of this may include cold showers if you use hot water faster than the tank heats up water in storage.

Tankless water heaters conversely heat water as it travels from the mains supply to your tap. Cold water flows into a tankless unit which uses a far more intense electric current or blast of gas to rapidly heat water on the way out of your tap. The supply of hot water is therefore unlimited.

Benefits of a Tankless Hot Water Heater

Tankless water heaters are roughly the size of a small suitcase and can heat approximately 10-22L per minute. They are particularly effective in large households when multiple hot water requirements at one time call for a more efficient way to heat water.

How Much Does A Tankless Hot Water Heater Cost?

Most tankless hot water heaters can be 24-34% more efficient than traditional hot water storage tanks. However, this value decreases the more hot water is used per day. A typical family can save $150 per year by using a tankless hot water heater.

A tankless water heater, however, will cost up to three times more than a conventional water heater to buy and install. In Australia, a tankless hot water heater will cost between $1470 and $2510 to buy and install. A large segment of the value of a tankless hot water heater is the installation, which may require upgrading existing plumbing and gas infrastructure to cater to the new system.

As is the case with most energy-saving appliances, consumers should carefully evaluate the costs of a tankless hot water heater against the long-term savings to determine which is the right choice. Water usage should also be factored in to this decision to ensure that you have enough hot water supply to cater to your household’s needs. If you currently face cold showers regularly, then a tankless hot water heater is probably for you.
