Water Heater Troubleshooting 101: 4 Common Problems & How To Fix Them

Tankless water heaters are an ideal option for many homeowners because they are energy efficient and have a long lifespan. 

However, like all appliances, tankless water heaters can experience problems from time to time. 

Let’s examine some of the most common problems with tankless water heaters and how to fix them. 

We will also answer the question: Is it time to replace your tankless water heater?

Water Heater Troubleshooting 101: 4 Common Problems & How To Fix Them

Common Problems with Tankless Water Heaters

There are a few common problems that can occur with tankless water heaters:

The most common problem would be the unit needing to start. The cause may be clogging on inlet screen, shower-head or fixtures. It could be due to lack of power. And it could be from an improper installation or malfunction.

1. Leaking or Dripping

Here are some possible causes and solutions for leaking or dripping:

  • A loose pipe connection can cause leaking. Make sure all connections are tight.
  • A broken seal can cause dripping. Inspect the seals and replace them if necessary.
  • Freeze damage from exposure to low temperatures and backdrafts.

2. Poor Temperature Regulation

Does your tankless water heater need to provide more hot water, or does the water temperature fluctuate too much?

Here are a few things that could be causing this problem:

  • Main gas valve is not opened – check the valve is fully opened. 
  • Cold water supply is too high – adjust the cold-water supply valve. 
  • Improper operation for water temperature adjusting – turn the water and gas valves to the correct position. 
  • Flushing is recommended for the heat exchangers, not the pipes. Blockage may prevent units from starting a decrease in temperature.

If the problem persists, it might be a device malfunction. It may be time to contact the gas water heater’s customer service or replace your tankless water heater.

3. Loud or Strange Sounds

Is your tankless water heater making loud or strange noises? It may indicate a problem with the heating element, the igniter, or the gas pressure. 

Call for professional assistance immediately if you hear any of these noises from your tankless water heater.

4. Corroded Parts

Corrosion can cause severe damage to the unit and may even lead to failure.

Here are 3 things you can do to help prevent corrosion:

  • Keep the unit clean and free of debris. This will help reduce the chances of corrosion.
  • To properly maintain and clean your tankless water heater, flush those mineral deposits at least once a year to prevent the walls inside its heating chamber from corroding. 
  • Make sure the unit is properly ventilated. Proper ventilation helps prevent moisture buildup, which can lead to corrosion.

Is It Time To Replace Your Unit?

If your tankless water heater is experiencing any of these common problems, it may be time to replace your unit. 

You can do a few things to prolong the life of your tankless water heater and avoid needing to replace it prematurely. 

  • Make sure to descale it regularly according to the manufacturer’s instructions. This will help prevent mineral buildup, which can lead to corrosion and other problems. 
  • Flush the mineral deposits from your tankless water heater at least once a year to ensure proper maintenance and cleaning.

If you decide to replace your tankless water heater, choose a high-quality unit from a reputable brand. 

6 brilliant things you didn’t know about your propane instant water heater

Are you looking for a more efficient, cost-effective, and environmentally friendly way to heat water in your home? Then you should consider the revolutionary propane instant water heater! This type of water-heating system has become increasingly popular because of its many benefits, including consistent energy efficiency and substantial savings over time. 

Find out why the propane instant water heater is the perfect solution for your home’s water needs.

 

The propane instant water heater in a nutshell

A propane instant water heater can revolutionize your home’s water system by providing near-instant hot water at a fraction of the cost of electric water heaters. Moreover, propane burns cleaner than other fossil fuels, such as oil and natural gas. 

 

Choosing the right size water heater

When it comes to choosing the right size water heater, there are a few factors to consider. The first is the number of people in your household. You also need to remain cognizant of the gallons per minute (GPM) demand from fixtures (for example, a shower demands 1.5 to 2.0 GPM while a bathtub demands 4 to 5 GPM).

There is also the climate. If you live in a cold climate, you’ll need a bigger water heater because it takes longer to heat up the water. Conversely, if you live in a hot climate, you can get away with a smaller water heater.

The next factor to consider is your home’s water usage. If you have a lot of appliances that use water or if you have a big family, you’ll need a bigger water heater. On the other hand, if you only use water for basic needs like cooking and cleaning, you can get away with a smaller unit.

 

6 brilliant things you didn’t know about your propane instant water heater

1. You can save money on your water bill. 

A propane instant water heater can help you save money on your water bill by providing hot water on demand, which means you won’t have to waste money heating water that you’re not using.

2. You can have hot water anytime, anywhere. 

A propane instant water heater gives you the freedom to have hot water whenever and wherever you want it. Whether in the kitchen, the bathroom, or even outdoors, you can enjoy hot water in seconds. The only delay you might experience is from the purge of cold water in the pipes.

3. You never have to worry about running out of hot water.

With a propane instant water heater, you never have to worry about running out of hot water. Whether you’re taking a long shower or washing a large load of laundry, you can be confident that plenty of hot water will always be available.

4. You can save space in your home. 

A propane instant water heater is much smaller than a traditional storage-tank water heater, which means it takes up less space in your home. This is ideal if you live in a small space or want to free up some space in your home for other purposes.

5. You can reduce your carbon footprint. 

Propane is a clean-burning fuel that produces lower emissions than other fossil fuels like oil and natural gas. So, by using a propane instant water heater, you can help reduce your carbon footprint and do your part to protect the environment.

6. It’s easy to install and maintain. 

Installing and maintaining a propane instant water heater is relatively simple and straightforward, which makes it easy for homeowners to set up their own. Plus, these tankless systems require very little maintenance to keep them running efficiently.

 

Safety precautions 

If you’re considering a propane instant water heater for your home’s water system, it’s important to be aware of the potential safety hazards and proper maintenance techniques. Propane is a highly combustible gas, so it’s important to take precautions when handling and storing it. 

Make sure to keep the area around your propane tank and appliances well-ventilated, and never smoke or use open flames near propane tanks or appliances. If you smell gas, leave the area immediately and call your gas company.

The benefits of installing a point of use water heater for your shower

Taking a hot shower on a cold day is one of life’s greatest pleasures — but why settle for the lukewarm water that your standard shower can provide? Get ready to discover why having a point of use water heater in your shower is the way to go! 

What is a point of use water heater for your shower?

A point-of-use water heater is a small electric or gas water heater installed near your shower. It provides hot water on demand, meaning you only have to wait for the cold water in the pipes to purge to enjoy hot water. So, the closer the water heater is to the shower, the quicker you’ll have a steaming shower. That means you can save water and energy and enjoy a faster, hotter shower.

When sizing a water heater, the temperature map is a beneficial tool point of use water heater do you need for your shower?

This depends on a few factors, like the number of people showering and how long each shower takes. For example, if you are the only person using the shower and only need it for a quick rinse, then a small point-of-use water heater would be sufficient. However, you will need a larger unit if you have multiple people using the shower or if you take long showers.

It also depends on the temperature of the water source, which depends on the region (for example: think of the difference in temperature of water source in Minnesota and Florida) and on the gallons per minute (GPM) demand from fixtures (for example, a shower demands 1.5 to 2.0 GPM while a bathtub demands 4 to 5 GPM).

Pros of point of use tankless water heaters

There are several reasons why you should consider a point-of-use tankless water heater for your shower. 

You’ll never run out of hot water. 

The tank size with a traditional tank water heater limits you. Once the hot water in the tank is used up, you must wait for it to heat back up again. With a point-of-use tankless water heater, there’s no need to wait – hot water is available on demand.

They’re more energy-efficient. 

Point-of-use tankless water heaters only heat the water you need when you need it. This means they’re much more energy-efficient than traditional tank heaters, which keep a large quantity of water heated all the time, even when you’re not using it.

They take up less space. 

Point-of-use tankless water heaters are small and compact, so they don’t require as much space as a traditional tank heater. This makes them ideal for small homes or apartments where space is limited.

Cons of point of use tankless water heaters

If not appropriately installed, point-of-use water heaters can lead to inconsistent water temperatures and scalding and they may not start.  

Types of point of use water heaters

There are two main types of point-of-use water heaters: gas and electric. 

Gas tankless water heaters are typically more expensive than electric models but tend to be more energy efficient. 

Electric tankless water heaters are less expensive upfront but can be more expensive to operate over time. 

Factors to consider when purchasing a point of use water heater

  • The unit size. You’ll need to ensure the unit is large enough to meet your needs. 
  • The type of unit. There are two main types of point-of-use water heaters: electric and gas. 
  • Installation costs. If you’re uncomfortable installing the unit yourself, you’ll need to factor in the cost of professional installation when deciding.
  • Maintenance costs. All appliances require some maintenance, and water heaters are no different. Be sure to factor in the cost of any required maintenance when making your decision. 

Speak to a point of use tankless water heater agent if you have any questions.

Selecting according to region and heated water demand

  • 2 elements are key for sizing and selecting a proper tankless water heater:
    • Temperature of water source which varies according to location
    • Demand of heated water: GPM demand depending on type and number of fixtures and appliances
  • Taking this into account will prevent a lot of frustration on purchases and use
  • The first support material we have available for this process is the Temperature Map:temperature map
  • Note:
    • The map indicates the capacity of the model units according to location
    • Big difference in demand from a shower (1.5 to 2.0 GPM) and a bathtub (4.0 to 5.0 GPM)!
    • The bathtub is the fixture that demands the highest GPM
    • Difference in temperature of water source in the south and in the north
    • Water source temperature also varies if from the city, well, tank, stream, etc. If water is exposed to air (well or tank situation) it is colder.
  • The second support information is in the manual for each unit. There is a table that approximates the capacity of the water heater to raise temperature according GPM:
    • Consider, the more the GPM (more water volume running through the unit) the less the temperature rise, the less the GPM the more the temperature rise
    • Note tables consider a fixed temperature of water source or set temperature, so values are approximated

  • Warning:

    • GAS tankless water heaters do not work on high elevations/altitudes. As an industry rule of thumb, no tankless works properly above 4,000 ft. Marey units are not recommended above 2,000 ft. People use them on high elevation/altitude locations at their own risk, we do not recommend it. High altitudes do not have proper physical/environmental conditions for the combustion and exhaust processes of the units, in short, there is not enough air up there!
    • Electric units are not affected by altitude
