What Size Tank Water Heater Do I Need?

Choosing the right water heater size for your home is critical. Too large, and you’re wasting energy and money. Too small, and you may find yourself frequently running out of hot water. So, how can you determine the correct size for your needs? At Indoor Air Quality, Inc., we understand the importance of balancing energy efficiency and comfort, and we’re here to help guide you in choosing the appropriate water heater size for your Denver home.

Understanding Capacity & Consumption

When it comes to tank water heaters, the size refers to the water holding capacity. The right capacity will depend on your home’s hot water demand, which varies based on the number, type, and frequency of hot water usage (showering, washing dishes, doing laundry, etc.).

A good rule of thumb is to consider the busiest hour of the day — what is often referred to as the \”peak hour demand.\” Count up all the activities that use hot water in your home during that hour, and the total hot water needed is your peak hour demand.

General Sizing Guide

While individual needs may vary, here’s a general guide to water heater size:

• 1-2 People: A 30-40 gallon capacity tank
• 2-3 People: A 40-50 gallon capacity tank
• 3-4 People: A 50-60 gallon capacity tank
• 5+ People: A 60-80 gallon tank

Bear in mind that these are general guidelines. Other factors such as the number of bathrooms, appliances requiring hot water, and overall water usage can influence the ideal tank size.

Factors to Consider

1) First Hour Rating (FHR)

The first hour rating represents the gallons of hot water the heater can supply per hour, starting with a full tank. Matching the FHR to your home’s peak hour demand will ensure your water heater can keep up with your needs.

2) Fuel Type

Whether your heater is electric or gas-powered can determine the size you need. Typically, gas water heaters have a higher recovery rate, meaning they can heat more water faster than electric models. Therefore, you may require a larger tank size if you prefer an electric heater.

3) Home Size

Larger homes usually have more bathrooms and appliances, requiring more hot water, meaning a larger tank may be necessary.

4) Efficiency

High-efficiency models can provide hot water more effectively, meaning you might achieve sufficient hot water provision using a smaller capacity heater.
