In our guide, you can learn more about choosing 40-gallon water heaters or a 50-gallon water heater based on water usage, household size, available space, and energy efficiency. By the end, you’ll better understand differences of 50 gallon or 40-gallon water heaters for your home and cover your family water requirements. (Read Outside Fan Not Running When Heat Is On)

Choosing 40 or 50 Gallon Water Heater

Important Factors To Consider When Purchasing A Water Heater (Tank)

Regarding buying a new water heater tank, there are several important considerations to significantly impact your hot water capacity, energy efficiency, and overall satisfaction with the unit.

Tank Size: Hot Water Capacity Matters

The size of the tank plays a crucial role in determining the hot water capacity of your system. A larger tank provides more hot water reserves, reducing the chances of running out of hot water during peak usage times.

For smaller apartments and single-family homes, a 40-gallon tank is typically sufficient.

However, you can opt for a 40 vs 50-gallon water heater or an even smaller tank if desired. Mid-sized homes often benefit from a 50-gallon tank, while larger homes may require a 70-Gallon Tank Or Even using Two 40-Gallon Tanks (Totaling 80 Gallons).

Efficiency: Making Informed Decisions

With gas water heaters, various options exist, including gas, electric, conventional, heat pumps, natural draft, and induced draft systems. It might be tempting to choose the cheapest model available, opting for an energy-efficient water heater can save you money in the long run on your utility bills.

Conversely, higher usage and utility rates will cause higher costs per year. Estimating usage can be challenging without data, so it is advisable to assume average usage unless you have specific information about your hot water consumption.

For utility rates, refer to your gas or electric bill to determine the price per Therm or Kilowatt-hour. The Energy Guide accompanying the water heater will provide the assumed energy output and sometimes the rate used in their calculations.

Compatibility With Your Current Setup: Avoiding Unforeseen Challenges

One often overlooked aspect when buying a new water heater tank is ensuring compatibility with your current setup. Dimensional compatibility is crucial. So, always measure the space before upgrading from a 40-gallon to a 50-gallon water heater tank like a 40- or 50-gallon water heater or vice versa.

If you plan to switch from a gas-powered tank to an electric one (or vice versa). It may be necessary to hire a professional electrician or plumber to install the required gas line or dedicated circuit. (Read Ceiling Fan Slow)

Tank Construction Material: Considering Durability And Longevity

It may surprise you to learn you can purchase water heater tanks made entirely of plastic, as opposed to the typical steel construction for your current heater.Plastic tanks offer the advantage of a lifetime warranty and a significantly reduced risk of corrosion compared to metal tanks.

However, note that plastic tanks are more expensive than their metal counterparts for the initial cost. However, if you expect moving within the next decade, opting for a more affordable metal tank would be a practical choice.

Determining Home Water Heater Needs

As families grow and water usage increases, upgrading to a larger water heater becomes necessary. To help you determine what size water heater is the ideal size, let’s consider some key factors.

Tank-Style Water Heaters And Household Size

For tank-style gas water heaters, the number of users directly impacts the hot water demand.

Based on the number of people in your house and how much hot water is, you can estimate the required hot water tank capacity:

  • 1 or 2 people: 23-to-36-gallon water heater.
  • 2 to 4 people: 36-to-46-gallon water heater.
  • 3 to 5 people: 46-to-56-gallon water heater.
  • 5 or more people: over 56 gallons (add 10 gallons per additional person.

For an average family of four, 40-gallon gas water heaters are ideal as a hot water tank.

First Hour Rating (FHR): Beyond Tank Capacity

The first-hour rating of a water heater unit is as important as the size water heater tank regarding hot water capacity. This rating shows the volume of hot water the unit can deliver in one hour when the tank starts off completely full and is fully heated.

To illustrate, let’s consider a 40-gallon water heater tank with a 65-gallon first-hour rating. This means the unit can provide an additional 25 gallons of hot water within an even first hour rate.

When selecting a new water heater, it is crucial to factor in the first-hour rating. For instance, empty nesters may prefer a smaller tank with a high first-hour rating. This allows them to handle higher hot water demands when their children visit, while still being energy efficient during times of lower usage. (Learn How Much Does A Ceiling Fan Weight)

Let’s examine the approximate hot water usage for various activities:

  • Baths or showers (per person): 20 gallons
  • Hair Washing (per person): 6 gallons
  • Washing hands (per person): 2 gallons
  • Washing dishes: 6 gallons
  • Running a dishwasher: 14 gallons
  • Shaving: 3 gallons
  • Running a washing machine: 30 gallons

Tank-Style Water Heaters: A Reliable Choice

If you have sufficient space and prefer a tank-style water heater, it’s crucial to choose a model that fulfills your family’s hot water requirements.

Assessing Available Space

Before purchasing a 50-gallon electric water heater Lowes sells, ensure it fits within the existing space. Some electric water heater 50 gallon models can be quite sizable, reaching up to six feet in height and 22 inches in diameter.

Selecting The Perfect Tankless Water Heater Size

If you decide to go tankless, accurately sizing the water heater is essential. The key specification to consider is the significant difference of flow rate, which determines a 50-gallon water heater’s capacity to deliver hot water on-demand.

To calculate the required flow rate, follow these steps:

Step 1: Determine Peak Hot Water Usage

Identify the point when your household consumes the greatest amount of hot water, known as peak usage.

To estimate this, refer to typical flow rates per fixture:

  • Sink faucet: 1 gallon per minute.
  • Bathtub: 3 gpm.
  • Shower: 2.5 gpm.
  • Dishwasher: 3 gpm.
  • Clothes washer: 3 gpm.

Add up the flow rates for simultaneous shower activities during peak usage to determine the maximum amount of hot water you would require at once from your gas water heater.
