No matter what size gas water heater you choose, you can rest assured that you are heating water for a fraction of the cost associated with electric heaters. Choosing a gas water heater is perhaps the wisest choice when installing or replacing a hot water heater in your home because they are much more economical than their electric counterparts.
In fact, most gas water heaters operate on less than half of the cost associated with conventional electric water heaters. Considering that hot water heaters are the second largest user of energy in the home, finding a more economical solution is very wise indeed.
Natural gas hot water heaters are also very popular among homeowners because they reach their set temperature more than twice as fast as an electric water heater does. That means that you could probably run the dishwasher after your morning shower and still have hot water, not lukewarm water.
While gas water heaters heat water faster and cheaper than electric heaters, it is still very important to purchase the right size tank for your household needs. A gas water heater that is too small can still leave you showering in lukewarm water.
Most homes will require a 40 gallon gas hot water heater. This heater will take care of a moderate sized home with 3 to 4 occupants, two bathrooms, and a washing machine. Even once you have figured out which gas water heater is the right size for your home, you may want to purchase a size larger for a few reasons.
