Diameter Size of 50 Gallon Models

When it comes to 50 gallon water heaters, the diameter can vary pretty significantly depending on whether you choose a traditional tank or a tankless model.

For standard tank heaters, the diameter runs between 18-20 inches. I‘ve installed hundreds of units over my career, and the average is right around 19.5 inches across. This gives you a good amount of hot water storage without taking up too much space.

According to my supplier data, the most popular Rheem model (50 gallon tall) has an exterior diameter of 22 inches. Bradford White‘s 50 gallon unit comes in at 20 inches across. And A.O. Smith‘s ProMax averages around 19 inches in diameter.

In contrast, tankless heaters take up far less space since they don‘t store water internally. The average tankless unit has a diameter of only 8-12 inches! They can easily fit in closets or small spaces. However, they do need an external power source to heat water on demand.

When choosing between tank and tankless, think about your family‘s peak hot water needs. Do you need 50 gallons available at once? Or will a compact tankless heater meet your demands? This will help determine the best diameter size.

Height and Clearance Requirements

While diameter varies, 50 gallon tanks tend to be a standard height around 60-70 inches tall. This allows enough vertical room for all the internal components.

You‘ll also want to account for proper clearance on all sides during installation. According to the 2018 Uniform Plumbing Code, you need a minimum clearance of 6 inches around the sides of a water heater. This prevents any fire hazards or overheating.

I also recommend leaving at least 8-12 inches of clearance space for easier access during repairs or maintenance. Having a tight squeeze around your water heater can make it difficult (and dangerous!) to service.

In addition, a clearance of 18-24 inches above the unit is ideal. This gives you room to safely reach the water lines, electrical connections, and exhaust flue. It also improves air circulation so your water heater can operate more efficiently.

As a general rule of thumb, leave as much space around your unit as your room layout allows. Trust me – future you will thank you during repairs!

Costs of 50 Gallon Installation

Installing a new 50 gallon hot water heater costs $600-$800 for a basic tank model. Here‘s a breakdown of what‘s included:

• Water heater unit: $400-$500
• Labor: $200-$300
• Parts & supplies (pipes, connectors, etc): $50-$100
• Disposal fees: $25-$50 (if replacing existing unit)

So you‘re looking at $700 on average for a straightforward install. Now let‘s talk about the factors that can increase costs:

Type of Unit – Tankless heaters are $1,000+ to install due to more complex connections.

Location – Second floor or garage adds labor time for transporting the unit.

Age of Infrastructure – Upgrading pipes and wiring in an older home adds costs.

Size and Energy Efficiency – Larger or higher-efficiency units have a higher base price.

Additional Services – Permit fees, leak inspections, and venting can add costs.

In my experience, the total installation price can range from $600 for a basic tank model up to $2,500+ for a premium tankless install. My best advice is to get multiple quotes from licensed contractors before committing. This will give you the full price range for your specific situation.

I know installation costs can seem intimidating. But remember – having a properly installed, reliable water heater will save you money and headaches for years to come. It‘s worth investing in!

Signs Your Water Heater is Failing

During my years of repairing water heaters, I‘ve seen all the common signs of a failing unit. Catching these early can prevent catastrophic failure or flooding. Be on the lookout for:

• Strange noises – Clanking or rumbling sounds signal sediment buildup.

• Reduced hot water – If you aren‘t getting enough, the tank may be failing.

• Leaks – Check below the unit for drips or pooling water.

• Rusty/discolored water – Flakes coming through your faucets indicate corrosion.

• Longer recovery times – It takes longer to reheat the tank between uses.

• Faulty temperature and pressure (T&P) valve – This safety valve is dripping or leaking.

• Pilot light issues – The igniter keeps going out.

If you notice any of these warning signs, it‘s time to call a pro. Getting ahead of problems early can actually save you money compared to handling a full emergency failure. Don‘t hesitate to give me a call – I‘m always happy to come take a look and advise the best fix.

Pipe Size Recommendations

When it comes to supply line sizing, you don‘t necessarily need 3/4 inch pipe for a 50 gallon unit. The proper pipe diameter depends on:

• Length of the water line run
• Number of fixtures served
• Peak demand

In many homes, 1/2 inch or even 3/8 inch piping is perfectly adequate for a 50 gallon tank. These smaller sizes actually allow water to move faster and avoid stagnation issues. Of course, homes with longer supply lines or heavy water demand may require 3/4 inch piping.

My advice is to consult the manufacturer‘s recommendations for pipe sizing. Every home‘s layout is different, so take into account your specific needs. And don‘t be afraid to size down – bigger pipe doesn‘t always mean better performance.

Ground Clearance Regulations

Now, let‘s talk about why water heaters require 18-24 inches of clearance from the ground. There are a few key reasons:

Accessibility – Adequate height allows easy access for repairs, maintenance, and replacement when needed. You or a plumber shouldn‘t have to crouch or squeeze to work on the unit.

Ventilation – More open space improves air circulation, which allows the water heater to operate safely and efficiently. Stagnant air can cause corrosion and combustion issues.

Flood Risk – Extra ground clearance helps prevent water damage if a leak occurs. Appliances closer to the floor are more vulnerable.

Fire Safety – More space between the water heater and floor reduces fire risk, especially with gas models. Heat and flames have room to dissipate properly.

Manufacturer Specs – All major brands require at least 18 inches of ground clearance in compliance with codes. Always defer to their guidelines.

While it may be tempting to tuck your water heater into a tight spot, resist the urge! Proper clearance on all sides is so important for performance, safety, and longevity. Protect your investment by giving it room to breathe.

Most Reliable Brands

When it‘s time to purchase a new 50 gallon water heater, which brands rise above the rest? Based on my professional experience and conversations with other experts, these are the most reliable names in the industry:

A.O. Smith – Excellent customer service and parts warranty. Their ProMax line is top quality. Models range from $500-$1,200.

Rheem – Leading efficiency and very durable. Good for high demand. $400-$1,500 price range.

Bradford White – Stainless steel components and reliable delivery. $550-$950 for residential models.

American – Sturdy construction and budget-friendly. Only $350-$700 for most units!

Rinnai – Top choice for tankless with great temperature consistency. $1,100-$2,500 installed.

While not exhaustive, this list is a great starting point for dependable water heater brands that won‘t let you down. I always recommend doing some comparisons between a few companies to find the perfect match. And don‘t hesitate to ask me any specific questions – I‘m happy to share my knowledge!

Why Installation is Expensive

As a pro, I know firsthand the expertise and effort that goes into properly installing a water heater. Here are the key reasons it‘s pricier than a simple DIY job:

• Permits – Most areas require licensed pros with permits for water heater installs. This guarantees adherence to local codes.

• Labor – With limited space to work in and heavy lifting, an experienced installer saves time and injuries.

• Expertise – Professionals have specialized plumbing, electrical, and venting knowledge to do the job right.

• Safety – Mistakes made during installation can result in gas leaks, fire hazards, or flooding.

• Warranties – Manufacturer warranties require certified installers to stay valid. This provides you coverage.

• Parts – Contractors have wholesale supply chain relationships to obtain quality parts affordably.

• Inspection – Most localities need final inspection from the professional before sign off.

While a DIY install seems simpler, the many steps and safety considerations make hiring a licensed pro well worth the price. Their expertise provides peace of mind and prevents costly problems down the road.
