As a homeowner, you must anticipate potential needs, problems, maintenance, and repairs before they happen. This applies to all the systems operating in your home, including the oil heating system. 

It is probably time to give your oil heating system a thought if you have recently moved into a new home. You could either be someone wanting to install a new system in your new home, or you might need to replace your oil tank soon. 

Factors to Consider

In any case, you may be wondering what size of ‘tank’ would be the most appropriate. Before you choose a tank size, here are a few things you should consider. 

  • Size of the Current Oil Tank

If you are looking to replace your old oil tank, measure it before heading out to buy a new one. You must determine the dimensions and the storage capacity of your current tank. 

  • Available Space

When buying an oil tank for your home heating fuel, you must choose one that can fit in your house. You may be a newbie, or you may be planning to replace your old tank with a larger one. In any case, determine how much room you have to store a new oil tank. 

  • Number of Family Members

After calculating the amount of available space, determine your needs. You must invest in an oil storage tank that can hold enough heating needed for your home. If you have a big family, you may need to go for a larger-sized tank, and vice versa. On the other hand, newlyweds should consider their future needs. If they plan on growing their family in the future, it is best to go for a bigger tank than they currently need. 

  • Size of the House

While the space where you’re going to install the tank matters a lot, the size of the rest of your home is just as important. A good rule of thumb to determine oil tank size is to go by the number of rooms you need to keep warm. A house with 1 to 2 bedrooms needs smaller tanks while bigger ones are necessary for homes with 4 to 5 bedrooms. 

  • Consumption Habits

The size of your oil storage tank also depends on how much heating oil your household uses. You may want to consider the conscious consumers in your family and the annual winter vacations when most of your family will stay at home.
