1. Tankless water heaters are smaller, lighter and easier to install than a conventional water heater
2. Unlike a tank water heater, tankless water heaters never run out of hot water.
3. Traditional water heaters take up a lot of space while tankless water heaters hang on the wall saving you considerable floor space.
4. Tank water heaters store water which is a perfect breeding ground for bacteria. Tankless water heaters do not store hot water eliminating the risk of bacteria growth.
5. Tank water heaters have an average lifetime of only 2-9 years while tankless water heaters are designed to last 20 years or more.
6. Tankless water heaters maintain their efficiency for the life of the unit, while a conventional water heater becomes less efficient due to the annual build up of minerals.
7. Tank water heaters have an electric energy factor of .80 to .90 and a natural gas/liquid propane energy factor of .52 to .62. Tankless water heaters have an electric energy factor of .95 to .99 and a natural gas/liguid propane energy factor of .69 to .85.
How it Works:
Whenever you turn on a hot water faucet or have a hot shower, cold water travels through a pipe into the tankless hot water unit, where either a gas burner or an electric element heats the water. The faucet acts as a key for turning on the heating element to heat the hot water you need. The water is heated as it flows through the heating elements or heat exchanger. As the water pressure fluctuates, the heating element are adjusted to maintain a constant temperature and maximum energy efficiency. Once you turn the faucet off, the tankless hot water heating system also turns off.
