What Is the Average Cost to Install a 50 Gallon Gas Water Heater? The Ultimate Guide for Homeowners

Hey there! If you‘re a homeowner looking to replace your water heater, you‘re probably wondering: what will it cost to install a new 50 gallon gas model? This is a big purchase decision, so you want to make sure you budget appropriately and get the right system for your home‘s needs.

As your local home improvement expert, I‘ve helped dozens of homeowners through the new water heater installation process. In this comprehensive guide, I‘ll walk you through everything you need to know, from costs to considerations to maintenance. My goal is to provide insider tips to help you make the best decision for your family and budget.

Overview of Standard Installation Costs

The total cost to purchase and install a new 50 gallon gas water heater averages $1000-$1500, according to 2021 figures from HomeAdvisor. This estimate includes the cost of the unit itself ($500-$1000) along with labor ($650-$900 on average).

I always recommend getting multiple quotes from qualified local contractors, as prices can vary based on your location, material costs, and the complexity of the job. Be sure to get an itemized estimate so you understand exactly what is included in the price.

What Impacts the Labor Costs?

Several key factors determine how much you’ll pay in labor costs for installation:

• Complexity of the job – Basic installs in an unfinished basement may start around $650, while running new gas or water lines, adding ventilation, or other challenges can cost over $900 in labor.

• Your area – Labor rates fluctuate across the country. Larger metro areas tend to have higher hourly rates. I’ve seen ranges from $45/hr in small towns to over $100/hr in big cities for plumbing pros.

• Permits – Your city may require a permit for the install, which typically costs $50-$100 depending on location. Always check permit requirements.

• Materials/parts – For example, you may need expansion tanks, seismic straps, longer water lines, adapters, etc. which could add $100-$300 to the total bill.

• Removal of old unit – If the contractor has to drain and dispose of an existing water heater, this generally tacks on $50-$150 for labor and fees.

What‘s Included in a Standard Installation?

When you pay for a professional water heater installation, here‘s what‘s typically included:

• Removal and disposal of your old unit
• The new water heater tank
• Connecting the water lines to the tank with shutoff valve
• Gas line connections and exhaust venting
• Leak testing to check for safety
• Any required permits
• Haul away of old unit

Some contractors may also run a 1-year warranty on parts and labor – be sure to ask!

How Long Should a 50 Gallon Water Heater Last?

One big question I always get is "how many years can I expect this new water heater to last?"

The typical lifespan of a properly maintained 50 gallon gas water heater is 8-12 years. However, you can maximize the life of your new investment with annual maintenance.

Here are a few signs that your water heater may be nearing the end of its useful life:

• Leaking or rust around the tank
• Discolored/sulfur smelling hot water
• Sediment buildup in the tank
• Inability to keep up with hot water demand
• Tank is over 10 years old

Catching problems early maximizes the chances your contractor can flush the tank or make repairs to extend the life of your existing unit.

On average though, most homeowners find themselves needing a new gas water heater right around that 10 year mark. At that point, replacement is usually the better option since new models are much more energy efficient.

Speaking of efficiency…

Gas vs Electric Water Heaters: Key Differences

When choosing a new unit, one of the top decisions is gas vs electric. Let‘s quickly compare the pros and cons:

Gas water heaters

Pros:

• Heat water faster
• More energy efficient; lower operating costs
• Higher first hour rating delivers more hot water at once

Cons:

• Higher upfront installation cost
• Need ventilation and gas line
• Annual maintenance required

Electric water heaters

Pros:

• Lower purchase price
• Easier to install; no gas line needed
• Lower yearly maintenance

Cons:

• Slower recovery time
• Less efficient; higher electrical costs over time
• Lower first hour rating

Bottom line – for most families, a gas tank water heater makes the most sense for performance and efficiency. Just be sure to account for installation and ongoing maintenance in your budget.

Now let‘s review sizing…

What Size Water Heater Does a Family of 4 Need?

One of the most common questions I get from homeowners is "what size water heater do I need for my family?"

The right tank size depends on two key factors:

1. Number of people in your household

2. Amount of hot water used daily

For a family of 4, the recommended water heater size is typically 50 gallons. This provides around 7-10 showers‘ worth of hot water.

However, if your family takes long or frequent showers, has teenagers at home, or runs multiple hot water appliances at once, consider sizing up to a 65 or even 80 gallon model.

A few tips:

• Take inventory of all sinks, showers, dishwasher, washing machine. More fixtures = bigger tank needed.

• Calculate the minutes spent showering or bathing by each family member per day. Long hot showers can use 40-50 gallons!

• Add up the capacity of all appliances that use hot water.

• Check the first hour rating (FHR) on the water heater specs. This indicates how many gallons it can heat per hour.

• Remember to account for guest visits or peak usage times.

Take the time to calculate your daily requirements and size your new water heater accordingly. This ensures you get a model that can handle your household‘s hot water demand.

An undersized tank leads to frustration with lukewarm showers and running out of hot water. Getting the size right avoids having to upgrade again in just a few years.

Speaking of professional installation…

Should I Install a Water Heater Myself or Hire a Plumber?

I‘m often asked by handy homeowners if they can tackle a DIY water heater install to save on labor charges. I understand the desire to take on home projects yourself. However, when it comes to a gas water heater, I strongly advise hiring a licensed pro.

The risks of an improper install include:

• Gas leaks – This poses a major explosion risk if the gas line isn‘t securely connected.

• Carbon monoxide poisoning – Incorrectly sealed venting can leak toxic gas back into your home.

• Water damage – One small leak can turn into an expensive disaster.

• No permits – Your home insurance may not cover unpermitted work.

• Void warranties – DIY installs often void the warranty on new units.

Additionally, a professional will have the expertise to correctly:

• Size, select, and locate the heater.

• Connect venting and gas lines to code.

• Install seismic braces for safety.

• Integrate with your home‘s plumbing system.

• Optimize energy efficiency.

My advice is to get quotes from 3-4 local contractors and review licensing, insurance, and references before selecting your installer. Paying for a pro now avoids costlier risks and repairs down the road.

Choosing the Right Installation Contractor: 5 Tips

Speaking of hiring a qualified professional, let‘s review some tips for picking the best contractor for your water heater installation:

1. Verify Licensing

In most areas, plumbers must hold a state license to work on gas lines and water heaters. Ask to see the contractor‘s license information to verify.

2. Look for Specialized Training

Seek out contractors who have completed manufacturer training courses on properly installing new water heaters. This demonstrates expertise.

3. Require Proof of Insurance

Only hire a plumber who carries general liability insurance as well as workers‘ comp. This protects you from liability.

4. Check References

Ask for 2-3 references from recent jobs and call them. This gives you insight into their quality of work.

5. Compare Itemized Quotes

Get itemized estimates from multiple companies so you can accurately compare pricing.

Taking the time to do your homework pays off in finding the best pro for the job. Be sure to get any guarantees about pricing, timelines, or warranties in writing too.

6 Maintenance Tips to Maximize the Lifespan of Your Water Heater

To guarantee you get the most value from your new gas water heater, follow these maintenance best practices:

• Drain annually – Flush the tank to remove mineral deposits and sediment which can lead to corrosion.

• Inspect the anode rod – This sacrificial rod attracts corroding material away from the tank. Replace it every 3-5 years.

• Check pressure valve – Make sure the T&P valve isn‘t dripping, which could indicate excessive pressure.

• Test for leaks – Look for any puddles or moisture around fittings. Catch leaks early.

• Clear venting – Ensure exhaust vent pipes are clear of nests, leaves, etc. that could cause blockage.

• Check insulation wrap – Make sure insulation around the tank is intact to maximize efficiency.

Setting a reminder to service your water heater annually is a great way to maximize its life expectancy. Your plumbing tech can handle most of these maintenance tasks during routine service calls.

Should I Upgrade to a Tankless Water Heater?

Tankless water heaters are growing in popularity due to their greater efficiency and lower operating costs. However, they have some downsides to consider:

Pros of tankless

• Endless hot water on demand

• More energy efficient

• Longer lifespan; 20+ years

• Smaller size than tank models

Cons of tankless

• Higher upfront cost; $2000+ installed

• Require upgraded electrical panel in some homes

• May need whole-home recirculation system

• Output limitations for larger homes

Tankless models make the most sense for energy-conscious homeowners who can utilize tax credits, rebates, and the long-term savings. Get quotes on both to compare your total costs.

Should I Consider Alternative Water Heater Types?

Beyond traditional gas and electric models, there are a few newer water heating technologies I‘m often asked about:

• Hybrid heat pump – These use heat pump technology and electricity to pull heat from the air to help heat water. Lower operating costs than electric, but higher price tag. Worth considering if electricity is cheaper than gas in your area.

• Solar water heaters – Systems that use solar thermal panels to collect heat and reduce reliance on gas/electric. Involve high upfront costs but can pay off over time. Require ample roof space and sunlight.

• Condensing units – These extract more heat from exhaust gases, increasing efficiency by up to 10%. Worth the upgrade for high efficiency.

• Thermal recirculation – Recirculates cooled water back to the unit to be reheated, reducing waste. Requires larger pipes. Helpful for detached buildings.

Carefully weigh the pros and cons of these newer technologies. Get professional help determining if they make sense for your home and budget.
