Known as both an on-demand water heater and point of use water heater, tankless water heaters generate hot water instantly when you open the hot water faucet. The energy consumed is only used for heating the water that is needed for that explicit time. The unit then turns itself off when the faucet is closed, reducing energy costs over the lifetime of the unit. Since there is no regular heating and re-heating of water and no storage of hot water and as in a customary water heater, you’re not wasting energy when you don’t need it.
As you can see, there are a number of advantages to using a tankless hot water heater over a standard tank hot water heater. If you are in the market for convenience, luxury, and efficiency, tankless hot water heaters may be something that you find interesting. Check them out, you may just find your next home appliance!
