The importance of having the right water heater installed in your home cannot be neglected. However, installing too big or too small can cause problems like running out of hot water, unnecessary usage of water heater, and exorbitant energy bills. Identifying the optimal size required can help you make the best use of your water heater. There are multiple sizes of water heaters available, but to identify which size best suits your requirements, you need to determine your average water usage. For this, you will need to consider few factors.

Physical Placement

The first thing you need to do is make sure the size of the water heater you intend to buy actually fits its designated space in your home. Proper placement of the water heater is essential.

Household Space

Your household’s size and occupancy play a significant role in identifying the right size of the water heating system. For instance, to get a loose estimate, you may need 30-40 gallons of water for 1 or 2 people, 40-50 gallons of water for 2 to 3 people, 50-60 gallons of water for 3 to 4 people, and much more as the number of people increase. By this, you can ensure everyone in your home gets adequate hot water for their usage.

Fuel Source

You can further funnel down the options available by identifying if your water heater will use electricity, fuel, natural gas, liquid propane, or it will be connected to your boiler. Once you select one of these options, the choices will narrow down to a few, making your purchase decision easier.

Apart from this, it would be best if you also considered your peak hour demand and the system’s first-hour rating. Understand how.

Peak Hour Demand of the Day

The peak hour demand refers to that time of the day when your household makes maximum usage of the water heater. Showers typically make use of maximum hot water as compared to all other activities. If everyone in your household showers either during the day or during the night, then that particular part of the day becomes your peak hour demand. It helps you identify the highest amount of water you need in gallons during the busiest hour of the day.

First Hour Rating (FHR)

This is the step where you need to find a water heater with a first-hour rating within 1 to 2 gallons of your peak hour demand. FHR signifies the number of gallons of water the system can provide in a single hour, starting with a full tank of hot water. Every water heater has the first-hour rating. If the FHR of your heating system matches your peak hour demand, that specific heater will meet your requirements. You can look for a water heaters FHR either under the performance section, specifications or features.
