Gas vs. Electric
Fuel type is the first decision you need to make because it dictates your annual operating costs and installation requirements. While oil options exist, the modern market is dominated by gas and electric models.
Gas Water Heater
A gas water heater uses a burner at the bottom of the tank to heat water. As the internal temperature drops, the burner ignites to bring it back up to your set point.
These units run on natural gas or propane. While the initial price tag is often higher than electric models, gas is usually cheaper utility-wise in many areas, potentially saving you money over time.
Pros
- Faster recovery rate: Gas heats water much faster than electric elements, making it ideal for larger families.
- Works during outages: Since it doesn’t rely solely on the grid (depending on the ignition type), you might still have hot water when the power goes out.
Cons
- Higher upfront cost: You will generally pay more for the unit itself compared to an electric equivalent.
- Safety and maintenance: Gas units require proper venting to prevent carbon monoxide buildup and need regular safety checks.
Electric Water Heater
Electric water heaters rely on two heavy-duty coils inside the tank to heat water. They are generally simpler to install because they do not require gas lines or ventilation stacks.
However, they are slower to recover. An electric 50-gallon unit typically takes about 80 minutes to heat up fully, whereas gas is much quicker.
Pros
- Installation flexibility: Without the need for venting, you can install these in closets or tight spaces more easily.
- Safety: There is no risk of gas leaks or carbon monoxide poisoning with an electric unit.
- Lower initial price: These units are usually cheaper to buy off the shelf than gas models.
Cons
- Higher operational cost: Electricity is often more expensive per BTU than natural gas, leading to higher monthly bills.
- Slower recovery: If you drain the tank, you will be waiting longer for hot water to return compared to a gas model.
Things to Consider When Choosing a 50-Gallon Water Heater
Once you choose your fuel source, keep these performance metrics in mind to ensure you get the right fit for your home.
First Hour Rating
The First Hour Rating (FHR) is the most critical number on the spec sheet. It tells you how much hot water the heater can deliver in a single busy hour, starting with a full tank (1).
The formula looks like this:
Tank Capacity x 0.70 + Recovery Rate = First Hour Rating
For a 50-gallon tank with a decent recovery rate, the math might be:
50 x 0.7 + 55 = 90 Gallons
This matters because a 50-gallon tank doesn’t just give you 50 gallons of hot water; as you use it, cold water enters and begins heating immediately. If your household takes back-to-back showers while running the dishwasher, you want a high FHR to prevent that dreaded cold blast.
To pick the right rating:
- Identify peak usage: Determine when your house uses the most water (usually mornings or evenings).
- Calculate demand: Estimate how many gallons you use during that hour (showers, appliances, faucets).
- Match the FHR: Ensure the unit’s FHR meets or exceeds that peak demand number.
Uniform Energy Factor (UEF)
Formerly known just as Energy Factor (EF), the UEF measures efficiency. It determines how much hot water is produced per unit of fuel consumed (2). A higher number means the unit is more efficient and will cost less to run. Look for a UEF of at least 0.62 for a standard 50-gallon tank, though high-efficiency models go much higher.
Energy Star Certification
Not every heater makes the cut. An Energy Star certified 50-gallon water heater is, on average, 15 percent more efficient than standard code-compliant models (3). This certification is a quick way to identify units that will save you money on utility bills over the lifespan of the product.

FAQs
How Much Is a Good 50 Gallon Water Heater?
You should budget between $600 and $1,200 for the unit itself. Electric models are generally on the lower end of that spectrum, while high-efficiency gas models or units with long warranties cost more. Remember to factor in another $500 to $1,500 for professional installation.
How Long Do Water Heaters Last?
Most standard tank water heaters last between 8 and 12 years. Gas units often burn out slightly faster than electric ones due to the stress of the burner. Regular maintenance, such as flushing the tank annually and replacing the anode rod every 4 to 5 years, can significantly extend this lifespan.
Is a 50 Gallon Water Heater Good?
Yes, a 50-gallon tank is the industry standard for a household of 3 to 5 people. It provides a good balance of capacity and recovery speed. If you have a family of 6 or more, or a luxury bathroom with a massive soaking tub, you might need to upgrade to a 75 or 80-gallon unit.
How Many Showers Can You Take With a 50 Gallon Water Heater?
You can typically take 3 to 4 consecutive showers. A standard shower head uses about 2.1 gallons per minute. However, you don’t use 100% hot water; you mix it with cold. Practically speaking, you get about 45 minutes of continuous shower time before the water runs cold.
How Long Does It Take for a 50 Gallon Water Heater to Warm Up?
An electric 50-gallon heater usually takes 60 to 80 minutes to heat a full tank of cold water. A gas model is much faster, typically recovering a full tank in 35 to 45 minutes. This is why gas is often preferred for larger families with high demand.
Do I Need an Expansion Tank for My Water Heater?
In most modern setups, yes. An expansion tank relieves pressure built up by thermal expansion as water heats. Many municipal codes now require them because they prevent damage to your heater and plumbing pipes. If you are on a closed plumbing system (one with a check valve or pressure reducing valve), an expansion tank is mandatory.
