What Size Water Heater Should We Buy?

For a residence, having hot water is essential. Having hot water on demand when you need it is one of the most critical conveniences your house can offer. You have gone through the debate of going with a storage-tank water heater or a tankless system. Perhaps you are off-put by the high initial costs of a tankless system, or possibly getting one that has the flow rate you need is out of the question. If a storage-tank water heater is the best fit for your home and your budget, the next big question is, what size water heater do you need?

What Size Water Heater Should We Buy?

Salespeople might try to sell you the biggest one you can afford. They are pushing one that is bigger than you’ll need and will cost more money to run. To avoid spending more money both upfront and long term, think about the size of your family and what you will need hot water for.

If you are only going to use hot water on one thing at a time, then you can get away with a smaller water heater. While if you desire the capacity to be running the washing machine, the dishwasher, and taking a shower all at the same time, you’ll need a larger capacity.

The general rule of thumb, though, comes down to the number of people in your household. Think about how many people are living there, and how many people could live in the house. Maybe you are buying a home that your family can grow into. A five-bedroom house should be able to support at least five people.

Water heaters are a long term investment, and thinking ahead can prevent you from having to replace an inadequate system later. Natural gas and propane can pump out higher BTUs and heat more water faster. So with these fuel sources, you can get away with a smaller tank than if you decide to go electric.

What will you need for your household?

  • 1-2 people need a 30-gallon tank
  • 2-3 people need a 40-gallon tank
  • 3-4 people need a 40-gallon tank (natural gas or propane) or a 50-gallon tank (electric)
  • 5+ people need a 50-gallon tank (natural gas or propane) or an 80-gallon tank (electric)
