It can be difficult to know where to start when deciding on a water heating system that works with your family. Fortunately, plumbers offer many options and are knowledgeable about the products they offer. And if you are starting with a new home, there are even more options to consider. Usually when people think of hot water heaters, the image of the large white tank is the first thing that comes to mind.

Whether it is gas fired or electric, a tank water heater has been the tried and true system for many years. There are other options, though. For instance, you could go with a demand water heater, which do not have a tank like the conventional water heaters. With a demand water heater, a gas burner or electric element heats water only when you need it.

This means you don't have to heat water to only to have it sit in a tank. With this type of system, energy consumption can be reduced by ten to fifteen percent. There are things to consider though. This type of heater may not be perfect for every situation.

Think of how much hot water you currently use. Do you already have low-flow showerheads and faucets? If you do, that's great, because tankless systems work better with efficient delivery systems. Also consider how far away from the water heater your water uses are. If your home is designed with short runs from the heater to the faucet, a tankless heater can do the job. Your plumber can help you determine if you gas supply is adequate as well as the availability of proper venting.

If you decide that the storage tank method of hot water would best suit your needs, don't despair. It is possible to be energy efficient and have the water heater that fits your requirements. Consider a gas condensing water heater. It is similar to a standard gas hot water heater in that the burner heats the bottom of the tank and the flue gasses heat the water.

What makes it different is that instead of one flue straight up from the burner being used to heat water, the flue gasses are set to flow through a series of smaller pipes. This means that the water waiting to be heated comes into contact with more of the flue gases. Not only does this heat the water more efficiently, but it also reduces the temperature of the gasses being exhausted from the tank.

It all comes down to your individual needs. With the help of a professional plumber you can work out what will be best for your household. Think of the amount of hot water you currently use, as well as water saving efficiencies you already have in place. Accessing your plumber's knowledge will no doubt prove invaluable.
