There are pros and cons with both tank and tankless water heaters. What are they? What are the differences? Whether you prefer electric or gas, tank or tankless, there are differences in energy savings, in the maintenance and in installation of each. Experts believe that tank water heaters are more appropriate for homes despite the fact that the utility bill is higher. Tankless water heaters cost more to purchase, more to install and more to maintain.
The tank water heater, also known as the storage water heater, requires little maintenance and can be used in any home. They hold between 20 and 120 gallons of water, they require the use of a heating element and they are insulated. Even though they are insulated, heat escapes and depending on the size of the water heater and amount of water usage, homeowners may run out of hot water. Large hot water heaters cost more to use. While the pilot light on gas hot water heaters help to keep the water hot, most of this energy is lost during use.
Tankless hot water heaters never run out of hot water but they cannot be used in just any home. They require necessary changes in the wiring of the home. The homeowner may have to upgrade electrical breakers because the tankless hot water heaters use more electricity. When low-flow is used the water heater will not turn on. This type of water heater costs more to purchase, more to install and more to maintain. Hard water build up continues to be a problem for those who use tankless water heaters and a water softener must be used. Gas tankless hot water heaters may be more appropriate according to studies done by the Center for Energy and Environment in Minnesota. They say that homeowners saved 36% more energy than homeowners who used tank water heaters.
So which is better? The tankless water heater or the tank water heater? Homeowners do not have to update the wiring in the home with a tank hot water heater, while they may have to with a tankless hot water heater because of the large amount of electricity needed to operate them. Gas tankless water heaters may be the way to go because of energy efficiency. Tankless water heaters do not require storage of water, while tank water heaters do and may run out of hot water, especially for those who use large amounts of hot water, and the tankless water heater may not turn on if the homeowner doesn’t use a lot of hot water.
