Bigger is not always better, especially when it comes to water heaters. If you choose an oversized unit, you might end up spending too much money and energy on hot water you won’t use. Meanwhile, if you pick a smaller unit, you might always run out of hot water when you need it the most. That’s why when buying a new water heater, it’s important to choose the right size for your home. AllStar Plumbing, your expert in water heater repair in Westlake, LA, lists a few factors to consider below.

Household Size

How many household members are currently staying in your home? This is the first thing you should take into account when choosing a water heater. When you get the right size, water heater maintenance will be easier, and your unit will be more efficient.

If you’re planning to get a tank-type water heater, here’s a loose estimate you can follow:

  • 30-40 gallons — 1 to 2 people
  • 40-50 gallons — 2 to 3 people
  • 50-60 gallons — 3 to 4 people
  • 60-80 gallons — 5+ people

Meanwhile, a tankless water heater doesn’t have any storage. Instead, it offers a constant supply of hot water for the household. That might be the best option if you have a large household size. However, you have to think about how much water it can heat at a time by checking gallons per minute (GPM).

First-Hour Rating (FHR)

A qualified plumber in Westlake, LA will tell you to consider the first-hour rating (FHR) before buying a heater. The FHR shows how much water the tank produces in your house during a busy hour. This ensures that everyone gets a continuous supply of hot water, whether they’re showering, running the dishwasher, or doing their laundry at the same time.


The existing space in your home is also a huge consideration. If you buy a heater with a big tank and don’t have enough floor space, your water heater installation will be problematic. Ensure the size you settle on will fit perfectly in the space you have.
