When you first decide to replace your water heater, you will find that you have multiple options to consider. The two main categories of water heaters are tank and tankless. Each has its own benefits and disadvantages, thus you will want to weigh these heavily to determine what will work best for you.

What you need to know about a tank water heater system

A tank water heater system works by taking in water into an insulated tank and heating it until the water is used. The tank can hold large amounts of water and will allow users to utilize whatever is stored in the tank. However, because the tank space is finite, the tank can run out of the heated water. When you have a larger family or group of people, this can happen quite easily.

If the tank water heater system is made out of plastic, stainless steel, or copper, it will not leak, but if made out of any other materials, it can cause leaks and lessen the overall efficiency of the tank. The tank system will also naturally have mineral buildup in the tank after storing water over the years, which also lessens the efficiency as well as the amount of water that can be stored.

A typical tank water heater will last anywhere from two to nine years until it needs to be replaced. It can also take up a large amount of space in your home and need to be secured in some fashion in the event of earthquakes and other natural disasters. Some studies have also shown that the warm water that is held in the tank is more prone to bacteria and other germ growth.

The tank water heater is quite bulky and can be hard to handle, but must be elevated away from possible floods and kept far away from fumes that may be dangerous.

A question of price?

Knowing this, the first question you may ask is why people still have the tank system installed in their home. But the answer is complicated. Some homeowners are not willing to spend a little extra money for a tankless system that can end up paying for itself in a few short years. The expense is worth it due to the benefits that the tankless system can provide ? not to mention the lower energy bills.

But many homes still have tank water heaters installed; so many homeowners may never even give them another thought.

But a tankless system offers homeowners a way to heat their water without having the think about every drop that they use. However, there are specific benefits to having a tankless water heater that you will want to consider:

? Increased energy efficiency
? Longer life span
? Greater safety
? Ease of portability
? Healthy
? Guaranteed hot showers

A tankless water heater system allows families and couples the ability to have hot water when they need it ? not when the tank is full enough.
