Traditional Water Heater vs. Tankless Water Heater

Consumers today have a great deal of choices when it comes to replacing a worn out water heater.   Options include traditional water heaters, as well as tankless water heaters.  While both systems provide hot water, each of the systems does it in a different manner.  In addition, they both have features and benefits that will appeal to some, while not appealing to others.

Traditional water heaters heat water using electricity, natural gas and propane.  In general they are not as energy efficient as tankless water heaters, because the heating mechanism in a traditional water heater is constantly cycling on and off as it maintains the temperature of the water in the storage tank.  Traditional water heaters are available in a variety of sizes, depending upon the hot water needs of the homeowner.  One thing to keep in mind when selecting a traditional water heater is to look carefully at the recovery rate, which is the amount of time needed to heat up the cold water in the tank.  This in many ways is more important than the capacity of the tank.

Tankless hot water heaters, which are very popular in Europe and Asia, only heat water when it needed.  As a result they are generally up to 50% more efficient than traditional hot water heaters.  As with traditional water heaters, there are available in many sizes and if properly sized, it is virtually impossible to run out of hot water despite the fact that there is no storage tank!  Many consumers like tankless water heaters because of their ability to almost instantly deliver hot water to the faucet when it is turned on.  The reason for this is the speed that the water is heated, as well as the fact that the heater or heaters are often located near the faucet.

Replacing Your Water Heater

Most people don’t give much thought to replacing or upgrading their water heater until it breaks.  Typically, water heaters quietly give good service for years until they suddenly give out.  Ten to fifteen years is a normal life span for the average water heater.

Water heater problems generally fall into one of two categories.  They will eventually either stop heating the water or start leaking.  If your water heater is leaking, it’s definitely time for a new one.  Water heaters eventually corrode through the tank and start leaking, and when they do they are not repairable.

On the other hand, if your water heater has suddenly stopped heating water, you may consider having it repaired.  First, check to make sure that the problem is not simply an interruption in your electric or gas service.  If not, then a reputable plumber who handles a full range of plumbing services may be able to repair the problem.

However, keep in mind that as mentioned above, all water heaters eventually rust through and need to be replaced.  If your water heater is nearing the end of its lifespan, consider replacing it with a new energy efficient unit rather than having it repaired.  You may actually save money in the long run.  A reputable plumber will be able to determine what’s wrong with your water heater, how much it will cost to repair, and help you decide whether repair or replacement is the better option.

When shopping for a water heater, consider how much capacity you need.  A 40 gallon tank is the norm, but you may need a 50 gallon tank for a larger family or if you have higher hot water needs such as for a whirlpool or a hot tub.
