Frugal and Energy Efficient Living

With the storage tank gas water heater that has a standing pilot, one will continue to have hot water with the power out as long as they still have water and gas to the house.

Another reason is that the old style gas water heaters are very easy to fix. The most common problem that occurs with the old style gas water heater is the thermocouple which costs less then $10 and is rather simple to replace. Many homeowners can do this themselves thus saving on a service call. There are several youtube videos giving detailed step by step instructions on how to replace the thermocouple.

And with the storage tank water heater, a person has a emergency source of potable water in case there is an interruption in the water supply.

One should be aware that the high efficiency storage tank gas water heaters also require electricity to operate because they have electronic ignition.

Edit: But that's just me and my opinions based on my needs. For many people, a tankless water heater is a very good choice.
