Instant tankless water heaters have yet to gain popularity in the US, but they have been commonly used in Japan and Europe for decades. The primary benefit of having a tankless water heater is that you get to enjoy instant hot water only when you need it. Compared to the traditional water heater system which constantly heats up water in the storage tank, an instant hot water heater saves you more money on monthly bills while reducing natural gas use.
Kinds of tankless water heaters:
•    Point-of-use heaters are small and can service only one or two outlets such as the faucet in your kitchen sink and the bathroom shower. Because they are small devices, they are cheaper and can be fitted into cabinets close to the water outlet and can thus heat up water almost instantly.
•    Whole-house heaters are larger and more expensive but offer the advantage of heating up water in more than one outlet at a time. The downside is that there is a lag time of several minutes for the water to heat up.
Advantages of the tankless (instant) water heater system

The traditional water heater must constantly heat up the water storage tank in order to keep the water at a certain temperature. As such, it uses up energy all the time even during times when the water is not being used.
In contrast, a tankless water heater heats up water on demand, or only when you need it. This is a very energy-efficient system which could save you substantial amounts of money on your bills.

Electric units do not produce greenhouse gases and do not use up natural gas.
3. Eligible for tax rebates
Most tankless water heater units are eligible for a federal tax rebate of up to $300. This is subject to change so contact us to find out the latest rebate offers.
