What is a Tankless Water Heater?
A Tankless Water Heater is an installed appliance that heats your water on demand rather than continually heating and storing a large amount of water in a traditional hot water heater. Tankless water heaters, otherwise known as Instantaneous water heaters or Demand water heaters, are gaining popularity due to their small, compact design and energy efficiency.
 
Unlike traditional hot water heaters that continually heat a large amount of water whether or not you need it, tankless water heaters are set up to control the flow of water through heating elements on demand.

What are the advantages of a tankless hot water heater system?
Also known as either a point of use water heater or an on demand water heater, this innovative product generates hot water immediately when you open the hot water faucet. The unit then turns itself off when the faucet is closed, thus saving energy costs over the entire lifetime of the unit. The energy consumed is only for heating the water that is needed for that specific time. Since there is no storage of hot water and no constant heating and re-heating of water as in standard water heaters, you’re not wasting energy when you don’t need it.

The energy savings of the gas tankless water heater translates to dollar savings for you and reduced impact on our environment. Typical savings are approximately 30% of your energy usage. Furthermore, a tankless water heater produces an endless supply of hot water, provided you size the unit appropriately. Point of use water heaters are also designed to last for 20+ years and can be mounted to a wall to save space.

How does an electric point of use water heater work?
Same principle as the gas units, when a hot water tap is opened, the cold water enters the tankless water heater and triggers the heating elements to turn on. Your hot water tap acts as an ignition key for the energy used to heat the hot water you need. The water is then heated as it flows through the heating elements or heat exchanger.
