Though the tank water heater system has been available for years, scientists and engineers have determined that there are better ways of heating the water that you use in your everyday life. With a tankless water heater, you can enjoy the hot water that you expect without some of the hassle that you may have grown used to.

Tankless (sometimes known as on demand) water heaters do not store the hot water that you will be suing. These systems heat incoming water while it passes along a series of coils. This system allows the water heater to be much more energy efficient. Tankless water heaters are available in LP, electric, and natural gas models.

More energy efficient

A tankless water heater doesn't use a tank to store water, so it only heats what you will need to use, when you need to use it. This allows your home energy bills to be based on what you actually use, rather than on what the water heater has decided to store in the tank. The energy factor of a tankless system is .69 to .80 while the tank system is only .52 to .59. Clearly, the tankless system design is able to perform more efficiently.

More cost effective

While the initial costs of a tankless water heater may be higher, there is additional information that you will want to consider. A tank water heater system only has a lifetime of nine years, at the very most, while a tankless water heater can last up to twenty years because of its design. The tankless water heater system also maintains an efficiency of 82% over the course of its longer lifetime, while the tank system declines each year because of mineral buildup.

More space effective and safer

With a tank water heater, you need to have a bigger tank to hold more water, but this can take up a lot of space in your home. With a tankless system, you do not need the space of the tank ' there is no tank. Another concern of the tank water heater system is the fact that it can fall over in the case of an earthquake, necessitating it to be secured to the wall or floor. But the tankless water heater is fastened securely to a wall, lessening the chances of problems in the case of natural disasters and flooding. The tank water heater system is large and bulky, while the tankless system is small and light ' making it easy to install too.

More sanitary

With a tank water heater, you are storing warm water until it is ready to use. However this system creates the ideal breeding ground for bacteria and other germs. With the tankless water heater system, the water is always left cold until it is ready to be heated for use ' much healthier for everyone drinking or bathing in the water.

Longer lifetime

Without the worry of mineral buildup, the tankless water heater system is made to last twenty years without lessening in its efficiency. With the tank water heater, you will notice a decrease in efficiency over the much short lifespan as minerals build up from storing water in the tank.

Don't run out of hot water again.

But what most homeowners want to know is whether they will have hot water when they need it. With the tank water heater, this isn't something that can be easily predicted. However, with the tankless water heater system, you can always expect the water that you need at the temperature that you want.
