Tankless Water Heater Vs Conventional Water Heater

Traditional tank style water heaters come in a large variety of sizes and shapes, but if you are using one for your entire home, you can guarantee that it will be quite a bit larger than a tankless water heater. Electric tankless water heaters are usually about the size of a briefcase, while their gas counterparts are approximately the size of a suitcase. With either power source, you are usually looking at saving a considerable amount of space if replacing a traditional tank.

In the past, traditional tank water heaters were built to last. It wouldn't be unusual for a water heater to last twenty years with proper maintenance. Most of the traditional tanks on the market today are lucky if they last the average 8 - 12 years. Due to their lack of water storage, tankless water heaters often last quite a bit longer. Gas powered units will usually last about 15 - 20 years, while their electric counterparts will last 30 - 40 years.

One of the biggest benefits of tankless water heaters is financial. Although tankless usually cost slightly more to purchase than a traditional tank, they quickly make this back and more with their lower operating costs. Compared to a traditional electric tank water heater, a tankless will usually save a homeowner 40 - 50 percent on their water heating bill. When taken over their longer lifespan this savings can add up to a substantial amount.

Larger families are often most impressed with a tankless water heaters ability to provide an endless stream of hot water. In most homes with a traditional tank, the third person to take a shower in the morning either has a shortened or a cold shower as the tank has been depleted and must get up to temperature again. Since tankless water heaters heat the water as it flows through, you can run it for as long as you like, and never have the water go cold.

Another great advantage to having a tankless heater is that once it is installed there will never be a need to call a plumber for a tank cleaning or repair. In case of a malfunction the system turns itself off and provides analytic and diagnostic information. There are also no safety issues because there is no permanent pilot and its burner, electronically ignited, comes on only when hot water is needed. The electronics also monitor the incoming water pressure and flow as well as the outgoing flow and water pressure, so hot water is always guaranteed.

With their smaller size, longer lifespan, greater efficiency, and ability to produce endless amounts of hot water, tankless water heaters offer a great many benefits over traditional tank water heaters.
