If you look at conventional water heater can make up for up to 20 percent of overall energy costs. This is also because traditional water heating systems utilize a tank for storage of water that can be supplied later. However, these can waste a lot of energy due to standby loss. This is actually water that is not used. The best way to save energy and reduce electricity bills is to use a tank less water heater.

These water heaters do not come with a storage tank and can easily standby loss of heat loss. These are considered to be the best energy savers. These are also energy-efficient. They offer hot water only when required. This is done by activation of the water flow via a special system. The heating apparatus is fueled via use of electricity, propane or gas. With the flow of gas, the water gets heated to a temperature that is preset. The device stops working as soon the shower or faucet is turned off.
