Tank vs. Tankless Water Heaters – Which Is Right for You?

Tank vs. Tankless Water Heaters - Which Is Right for You

If you’re planning to replace or install a water heater, choosing the right type is important for long-term efficiency, comfort, and cost. Most homeowners will choose between a tank water heater, which stores and heats a large amount of water, and a tankless water heater, which heats water only when it’s needed.

At 412 Plumbing, we work with Pittsburgh homeowners to assess their water usage, space, and budget to determine which option is the best fit. Below, we’ll outline how each system works, compare their advantages and limitations, and help you understand what might work best in your home.

What Is a Tank Water Heater?

A tank water heater is the traditional model installed in most older and many newer homes. It includes an insulated tank that holds a fixed volume of water, typically ranging from 30 to 80 gallons. The water inside the tank is heated continuously so that it’s ready for use whenever you turn on a faucet, run a washing machine, or start the dishwasher.

Once the hot water in the tank is used up, cold water flows in to refill it, and the system begins reheating. The time it takes to fully reheat the tank varies depending on the tank size, temperature setting, and whether it’s gas or electric.

How Tank Water Heaters Are Powered

Most tank models use either natural gas or electricity as their energy source. Gas water heaters usually recover hot water faster than electric models, which can be an important consideration if your household uses a lot of hot water at once or back-to-back.

Gas models tend to be slightly more efficient in cold climates like Pittsburgh because of their quicker recovery time and lower operating costs over time. However, they may also require proper venting and gas line availability, which can add to the installation cost if not already in place.

Installation and Maintenance

Installing a tank water heater is usually more straightforward, especially if you’re replacing an older tank model with a similar one. In many cases, existing plumbing and electrical or gas connections can be reused.

Routine maintenance includes:

  • Flushing the tank annually to remove sediment buildup
  • Checking the anode rod to prevent corrosion
  • Inspecting the temperature and pressure relief valve

Failure to perform basic maintenance can shorten the lifespan of the unit and reduce efficiency. On average, tank water heaters last about 8 to 12 years depending on water quality and usage.

Storage and Space Requirements

A tank water heater takes up more space than a tankless model and is typically installed in a basement, utility room, or closet. In homes with limited space, especially in city row houses or apartments, this can be a limiting factor.

What Is a Tankless Water Heater?

A tankless water heater operates differently from a traditional tank model. Instead of storing hot water in a tank, it heats cold water as it passes through the system. When you turn on a hot water tap, water flows through a heat exchanger that brings it up to the desired temperature almost instantly.

Energy Use and Efficiency

Because tankless systems heat water only when it’s needed, they don’t experience “standby heat loss”—a common issue with tank systems, where energy is constantly used to keep water hot. This can result in measurable energy savings over time, particularly in homes that don’t use hot water continuously.

The U.S. Department of Energy estimates that tankless water heaters can be 24–34% more energy efficient than traditional tanks for households that use 41 gallons of hot water per day or less. For homes that use more hot water, the efficiency gap may narrow, but the energy savings still tend to be favorable in the long run.

Hot Water Supply

One of the primary benefits of a tankless system is the ability to supply hot water continuously—as long as water is flowing and the unit is operating properly. However, tankless systems have a limited flow rate. This means that if several people are using hot water at the same time, the system might struggle to meet demand unless it’s sized appropriately.

In some cases, homeowners may need to install more than one unit to supply sufficient hot water for larger homes or high-usage households.

Installation and Upgrades

Tankless water heaters have a higher upfront cost than tank models. In addition to the price of the unit, installation may require electrical upgrades, new venting, or gas line changes. Homes that have never had a tankless unit before might require more extensive modifications.

That said, once installed, tankless systems require less physical space and are typically wall-mounted. They are a good fit for homes with limited floor space and can be installed in smaller mechanical rooms, closets, or utility spaces.

Maintenance and Lifespan

Tankless water heaters should be descaled annually, especially in areas with hard water. This prevents mineral buildup that can reduce efficiency and damage components over time.

With proper maintenance, tankless systems can last 15 to 20 years or more. The longer lifespan may help offset the higher initial investment, depending on the system’s usage and maintenance history.

Which System Is Better for Your Pittsburgh Home?

Choosing between a tank and tankless water heater comes down to a few practical considerations. Here’s how to evaluate your options based on your needs.

Household Size and Usage

Tank models are usually a good fit for small to medium households that use hot water in a more routine or staggered way. If you typically run one or two fixtures at a time and don’t have large spikes in demand, a traditional tank may work well.

Tankless systems can serve homes with greater or more unpredictable hot water usage. However, it’s important to choose a unit that matches your household’s peak water demand. For homes with four or more people, it may be necessary to install multiple units.

Energy Efficiency Goals

If energy savings are a top priority, tankless systems generally use less energy over time. Tank systems tend to cost less upfront but use more energy due to the need to maintain stored water temperature around the clock.

Installation Cost and Long-Term Value

Tank water heaters are typically less expensive to install and replace. However, they also need to be replaced more frequently—usually every 8 to 12 years. Tankless systems are more expensive up front, but their longer lifespan and lower energy use may offer greater value over time.

Available Space

Tank water heaters require floor space and clearance, while tankless models are compact and wall-mounted. In homes with limited utility space, a tankless model may be easier to accommodate.

Local Factors to Consider in the Pittsburgh Area

Pittsburgh’s cold winters can affect how well a water heater performs. Incoming water temperatures are colder in winter, which means water heaters need to work harder to reach the desired temperature. Tankless models must be appropriately sized to account for this seasonal drop in water temperature.

Older homes in Pittsburgh may also need electrical or plumbing updates to support a tankless system. In these cases, a professional assessment is recommended to determine whether additional upgrades are required.

Some local utility providers also offer incentives or rebates for installing energy-efficient water heaters, which may help offset installation costs. Be sure to check with local programs or ask your plumber during your consultation.

Preventing Sewer Issues Caused by Cold Weather

Preventing Sewer Issues Caused by Cold Weather

Winter can be a beautiful season, but it also brings its share of challenges when it comes to maintaining your sewer system. At 412 Plumbing, we have seen firsthand the damage that cold weather can cause to sewer systems. To help you keep your sewer system in working order this winter, we have put together a guide on the main issues you could face with your sewer system and how to resolve them before more serious damage is done.

Signs Your Sewer System is Not Working Properly

Sewer systems are designed to be tough, but they can still experience issues during the winter months. Some of the most common signs that your sewer system is not working properly include sewage odor, frozen sewer vents, a frozen septic tank, and refreezing. These issues may also lead to slow or clogged drains, gurgling noises coming from your pipes, and even sewage backup in your home.

Pittsburgh is no stranger to cold winters. While the snow can look beautiful and provide children with the fun of sledding or building snowmen, the bitterly cold weather can cause a range of issues to your home’s sewer system, leading to costly repairs.

Some of the main issues we have seen during the winter months include:

Sewage Odor

One of the most common issues that homeowners face during the winter is a sewage odor. This foul smell is often caused by a buildup of decomposing waste in your sewer system due to freezing temperatures.

As the cold weather sets in, your pipes may freeze, causing a blockage that prevents proper flow and leads to a sewage backup. Not only is this unpleasant to deal with, but it can also be harmful to your health. To remedy this issue, it is important to have your sewer system regularly inspected and cleaned to prevent any blockages from forming.

Frozen Sewer Vents

Another problem that arises during winter is frozen sewer vents. These vents are designed to release gases from your sewer system and keep them from building up in your home.

However, when they freeze, the gases have nowhere to escape, causing pressure to build up and potentially lead to a burst pipe. Additionally, when the vents are frozen, it can affect the function of your plumbing fixtures and appliances. Signs you have a burst sewer pipe include a gurgling sound when you flush the toilet, run water in your sink, or slow drainage.

To prevent a burst sewer pipe, it is important to have your frozen vents properly thawed by a professional plumber. Attempting to thaw them yourself could lead to further damage or injury.

Frozen Septic Tank

If you have a septic tank, it is at risk of freezing during the winter months. This can happen if there is not enough insulation or if the tank is not regularly pumped out. Frozen septic tanks can lead to backups and overflows, causing damage to your yard and potentially contaminating the surrounding area. Signs of a frozen septic tank include slow drains, gurgling noises, and sewage odors.

To prevent this issue, it is important to have your septic tank regularly inspected and pumped and ensure it is properly insulated.

Refreezing

After a sewer issue has been resolved, refreezing is still a risk. This occurs when the temperature drops after a temporary thaw, causing any remaining water in your pipes to freeze again. Refreezing can lead to burst pipes and blockages, causing further damage to your sewer system.

To prevent refreezing, you should always have any sewer issues addressed by a professional plumber and make sure your plumbing is properly insulated.

Dangers of Trying to Resolve Sewer System Issues Yourself

While it may be tempting to try and fix sewer system issues yourself, particularly in an emergency situation, it is important to leave these tasks to the professionals. Attempting to resolve plumbing issues without the proper knowledge and tools can result in further damage or even injury. This can lead to higher costs for repairs and can also delay the repairs, leaving you without a functioning sewer system.

Tips for Maintaining Your Sewer System Throughout The Winter

To keep your sewer system in good shape during the winter, here are some tips to follow:

Schedule regular inspections and cleanings with a professional plumber.
Make sure your plumbing is properly insulated to prevent freezing.
Keep an eye out for any signs of issues and address them immediately.

Common Causes for Clogged Sewer Lines

clogged sewer line inspections

Maintaining clear sewer lines is crucial for the health and functionality of your home’s plumbing system. Clogged sewer lines can lead to severe problems and potential damage, resulting in costly repairs and significant inconvenience. Understanding the common causes of these clogs and implementing preventive measures can save you time, money, and stress. At 412 Plumbing, we are committed to helping you maintain a healthy plumbing system with professional advice and services.

Common Causes of Clogged Sewer Lines

Tree Roots

One of the most common and damaging causes of sewer line clogs is tree roots. Tree roots are naturally attracted to the moisture in sewer lines. Over time, they can infiltrate even the smallest cracks in pipes, growing and expanding within them. This intrusion can lead to significant blockages and damage. Signs of tree root intrusion include slow drains, gurgling noises from toilets, unpleasant odors, and water backups. If you suspect tree roots are causing issues, it’s important to address the problem promptly to prevent further damage.

Grease Buildup

Another frequent cause of clogged sewer lines is grease buildup. Grease and fats from kitchens can solidify within pipes, creating stubborn blockages that are difficult to remove. Pouring grease down the drain might seem harmless, but it can accumulate and harden, leading to serious clogs. Preventive measures include avoiding pouring grease down the drain, using strainers to catch food particles, and regularly cleaning kitchen drains with hot water and vinegar. These practices can help keep your pipes clear and free-flowing.

Foreign Objects

Foreign objects are a common cause of sewer line clogs, and many households unknowingly contribute to this problem. Items like wipes, diapers, and feminine hygiene products should never be flushed down the toilet, as they do not break down easily and can cause blockages. Proper disposal involves placing these items in the trash instead. Educating household members on what should and should not be flushed can prevent many clogs and keep your plumbing system running smoothly.

Hair

Hair can accumulate in drains over time, leading to significant clogs in sewer lines. This is especially common in showers and bathroom sinks. To prevent hair from entering your plumbing system, consider installing hair catchers in showers and sinks. Regularly cleaning out hair from drains and opting for professional drain cleaning services can also help maintain clear sewer lines.

Sagging Sewer Lines

Over time, sewer lines can sag or “belly,” causing water to pool and debris to accumulate. This can reduce water flow and increase the risk of blockages. Sagging sewer lines are typically caused by soil conditions, ground settling, or improper installation. Addressing this issue often requires professional assessment and repair to ensure the integrity and functionality of your plumbing system.

Pipe Scale

Mineral deposits, also known as pipe scale, can form inside pipes, leading to restricted water flow and clogs. Hard water is often the culprit behind pipe scale buildup. Preventing this issue involves scheduling regular professional pipe descaling services and using water softeners if you have hard water. These measures can help keep your pipes free of mineral deposits and ensure optimal water flow.

Flushing Debris

Items like paper towels, cotton balls, and other debris should never be flushed down toilets. These items do not break down easily and can cause significant blockages. Educating household members about proper flushing practices is crucial. Only toilet paper and human waste should be flushed, while other bathroom waste should be disposed of in bins. Posting reminders in bathrooms about proper flushing practices can also be helpful.

Preventive Measures

Regular Maintenance

Regular maintenance is essential for the early detection and prevention of clogs. Scheduling regular sewer line inspections can help identify potential issues before they become major problems. At 412 Plumbing, we offer comprehensive sewer line inspections, professional drain cleaning, and routine maintenance plans to keep your plumbing system in top condition. Regular maintenance not only prevents clogs but also extends the lifespan of your plumbing system.

Proper Waste Disposal

Adopting safe waste disposal practices is key to keeping your sewer lines clear. This includes disposing of grease and food waste in the trash, using garbage disposals responsibly, and avoiding flushing non-biodegradable items. By following these recommendations, you can significantly reduce the risk of clogs and maintain a healthy plumbing system.

Installations to Prevent Clogs

Installing devices like hair catchers, grease traps, and other preventive installations can significantly reduce the risk of clogs. These devices help catch debris before it enters your plumbing system, reducing the need for frequent maintenance. The benefits of these installations include preventing debris from entering pipes, reducing maintenance needs, and prolonging the lifespan of your plumbing system.

Recognizing the Signs of a Clogged Sewer Line

Slow Drains

Slow drains are often the first sign of a developing clog. If you notice slow drainage in sinks, showers, or tubs, it’s essential to take immediate action. Using a plunger or drain snake can sometimes clear minor blockages. However, avoiding chemical drain cleaners is recommended, as they can damage your pipes. If the issue persists, contact 412 Plumbing for professional assistance.

Unpleasant Odors

Foul smells from drains or around the home can indicate a clog in your sewer line. If you detect unpleasant odors, check for blockages in drains and clean out traps and strainers. Persistent odors should prompt a call to 412 Plumbing for an inspection to identify and address the underlying issue.

Gurgling Sounds

Gurgling noises from drains and toilets can signal a blockage in the sewer line. These sounds occur when air is trapped in the pipes due to a clog. If you notice persistent gurgling noises, especially if multiple drains are affected, it’s time to call a professional plumber for an inspection.

Water Backups

Water backing up into sinks, tubs, and toilets is a serious issue that requires immediate attention. Water backups can cause significant damage to your home and indicate a severe clog in the sewer line. If you experience water backups, stop using water in affected areas and contact 412 Plumbing immediately. Avoid attempting to fix the issue yourself, as improper handling can worsen the problem.

Work with a Professional Plumbing Company

Clogged sewer lines can cause significant damage and inconvenience. By understanding the common causes and implementing preventive measures, you can maintain clear sewer lines and avoid costly repairs. Regular maintenance and professional inspections are key to ensuring the health of your plumbing system. At 412 Plumbing, we are dedicated to providing expert sewer line inspection and maintenance services to keep your home’s plumbing in optimal condition.

Hot Water Heater Maintenance Guide

Residential Hot Water Heater

Preventative maintenance is key to extending the lifespan of your hot water heater for your commercial or residential building. Hot water heater maintenance not only helps to prolong the working condition of your hot water heater but also helps to keep energy consumption efficient and promotes the safety of the unit by catching issues before failures or accidents can occur.

Why Do I Need to Maintain My Water Heater?

Neglecting water heater maintenance can be dangerous. With a gas-fired water heater, fatal accidents can occur. Gas-fired water heaters should be checked regularly for issues such as gas leaks.
Water heaters that have tanks have features that will allow excess temperature and pressure to escape if there is too much buildup. These safety features need to be checked regularly by professionals to ensure they are working properly. If these features fail, tank explosions can occur.
Typically, a water heater can last for a decade without any maintenance. By conducting regular water heater maintenance, you can extend the lifespan of your water heater and catch any issues before they can become more serious. Over time, water heaters can develop a sediment buildup, especially if you have hard water, which can affect the efficiency of your water heater.

How Often do I Need to Perform Water Heater Maintenance?

If you have a commercial or industrial water heater, yearly maintenance is ideal. For residential water heaters, we recommend maintenance every six months. We recommend doing the maintenance during autumn before your water gets cold requires more warmth from water heaters to reach the desired temperature.
If you have hard water in your area, you will want to have water heater maintenance completed more often to ensure that your hot water tank is properly flushed and drained to remove the formed sediments and mineral buildup.
For those who plan to complete their hot water heater maintenance on their hot water heater, be sure to check the manufacturer’s warnings and follow the water heater maintenance checklist from 412 Plumbing. This will help to make sure that your maintenance is done correctly and safely.

Water Heater Maintenance Checklist

A water heater maintenance checklist can be sued by contractors, facilities managers, and homeowners to help them stay on track during their water heater maintenance tasks. There are five main steps that should be included on your checklist:

  1. Shut off the water heater. To prevent injuries such as scalding, you will want to shut off the water heater and allow it to cool overnight before you start your water heater maintenance.
  2. Look for leaks on pipes, joints, and check the valves. If you are checking for possible leaks, you can apply soapy water to the pipes and pipe joints. If bubbles appear, there is a leak. Follow the manufacturer’s instructions on the Temperature and Pressure valve to check that it is working correctly. You will also want to check the water pressure valve to ensure that it Is displaying the recommended water pressure of 40-60 psi during the day.
  3. Flush out sediment buildup. Before you begin flushing out sediment buildup, hook a hose to the drain valve. This will help improve your water heating efficiency and will also prolong the lifespan of your water heater.
  4. Check the anode rod. The anode rod protects the water heater lining and the inside of the tank from any damage or corrosion. The anode rod needs to be checked for corrosion.  Your anode rod will typically need to be replaced every 3-5 years. Refill your water heater tank. Close the drain valve and open the cold-water supply valve. Open one of your hot water faucets and let the water run for around 3-5 minutes. This will help ensure that there is no air remaining in the tank prior to turning the water heater back on.

It is crucial to check the manufacturer’s instructions on the use and maintenance of your water heater. We recommend having a water heater professional conduct your water heater maintenance.
