Also known as instantaneous or demand water heaters, tankless water heaters produce hot water only when required. As the name suggests, no hot water storage tank is used at all. Water is simply heated up in a boiler unit when the hot tap is turned on.

The more traditional tank heaters actually cost you more money since any hot water that is not instantly used sits in the insulated tank, which cools down over time rendering the money you spent on heating it up pointless! Another benefit of tankless water heaters is that you don’t have to wait until the water tank is full of hot water to then have a bath, shower, wash the dishes etc. Plus, you can spend as long as you like using hot water, rather than the time it takes for a tank to run out of water.

Tankless water heaters use either electric heating elements or gas burners to heat up the water on demand. The usual hot water rate is 2-5 Ga (7.6 - 15.2 Liters) per minute. Generally gas tankless heaters provide more heat and therefore hot water than electric versions. Some tankless water heaters are unable to create enough hot water for multiple simultaneous uses around the house, a more common problem in large households. This problem can easily be rectified by either installing a much larger 'whole house' tankless water heater, or by adding more of the usual size heater, or alternatively assigning extra heaters to household appliances that use particularly large quantities of hot water.

Before purchasing a tankless water heater make sure you carefully consider the fuel type (gas or electricity), location, size and demand, and lastly the application (what it is being used for).
