Tips on Proper Water Heater Sizing

Tips on Proper Water Heater Sizing

Not all water heaters are created equal. Even if you choose the best one on the market, it will only work efficiently with proper sizing and installation. There are several factors to consider when deciding on the right size, and as your dependable source of water heater services, Dynamic Drains is here to help. We share some helpful tips below.

1.  Household Size

The first thing you should take into account is the number of occupants in your home. If you are going for a tank-style unit for your water heater installation, you can estimate the capacity you need using the following guide:

  • 1 or 2 people – 23 to 36 gallons
  • 2 to 4 people – 36 to 46 gallons
  • 3 to 5 people – 46 to 56 gallons
  • 5 or more people – over 56 gallons

Of course, you should not rely on this estimate alone. You still have to further assess your hot water needs to determine the proper tank size. Undersized units tend to overwork and may require water heater repair in Ann Arbor, MI more often, while oversized ones will consume more energy than what’s necessary, costing you money.

2.  First-Hour Rating

Next, look for the first-hour rating (FHR). This pertains to the amount of hot water your unit can provide in an hour. One way to identify the proper FHR for your needs is to calculate how much water (in gallons) you use during the busiest hour of the day in your home. For example, if most people in your household take showers in the morning, you may consider that for your FHR. This may be a bit complicated to do, but an experienced plumber in Ann Arbor, MI from Dynamic Drains can guide you with this.

3.  Space Requirements

After getting a clear picture of your hot water needs, consider the available space you have in your home. Tank-style units take up a lot of space and are usually ideal in basements and closets. If you have limited space, a tankless water heater may be a better option. It can be installed on a wall and can fit in tight areas.
