What is a Propane Hot Water Heater?

A propane hot water heater is a type of appliance that uses propane gas to heat water.

Propane hot water heaters mix air into the burner chamber with propane gas. The mixture is ignited, and the resulting flame heats a metal coil inside the chamber.

Water is circulated through the coil, and as it passes through, it picks up heat from the chamber and is warmed.

Propane is a highly flammable gas, so there are some safety concerns about using this type of heater indoors.

Are Propane Hot Water Heaters Safe for Indoor Use?

Yes, propane hot water heaters are safe for indoor use.

In fact, propane is one of the safest heating fuels available.

When used correctly, there is no risk of explosion or fire. However, you should take a few safety precautions when using a propane hot water heater:

Safety Guidelines for Using a Propane Hot Water Heater Indoors

Some important safety guidelines exist for using a propane hot water heater indoors.

  • Make sure your gas and venting installations are set up correctly by following the owner’s manual.
  • Make sure the area around the heater is well-ventilated. Propane is a combustible gas, so it needs oxygen to burn. If the area around the heater is not well-ventilated, the replacement for combustion will not be proper.
  • Do not store combustible materials near the heater. This includes flammable liquids, gases, and rags or papers that could easily catch fire.
  • Have a qualified technician service the heater regularly to ensure it operates safely and efficiently.

The benefits of an under-sink water heater

Hot water is a vital resource that we all rely on daily, and it’s essential that the water we use is safe and comfortable to enjoy. 

As a homeowner, you might have experienced frustratingly long waits for hot water or inconsistent temperature when using your basin faucets. 

But did you know an under-sink water heater could solve these problems? 

Let’s explore why every homeowner should consider installing one of these compact yet powerful devices. 

Meet under-sink water heaters

If you’re looking for a way to have instant hot water at your sink without taking up too much space, a mini tank under-sink water heater is a great option. 

These compact water heaters can be installed easily and provide a steady hot water supply. 

Under-sink water heaters are available in different sizes, so choosing one appropriate for your needs is important.

How does an under-sink water heater work?

An under-sink mini tank water heater is typically installed in an upright position under the sink or it works as a “sandwich” unit to supply instant hot water to the point of use that is too far from the main water heater.

The water is heated by an electric heating element and stored at a pre-set temperature. 

When the hot water tap is opened, the heated water is pushed out of the tank, and hot water is delivered to the tap.

Benefits of an under-sink mini tank water heater

An under-sink water heater provides many benefits for those looking for an efficient, effective, and safe way to heat water. 

  • These units provide hot water at the point of use, allowing for reduced energy consumption and cost savings. 
  • They also save you time and money by delivering hot water faster than a conventional water heater.
  • Moreover, they are compact and require minimal installation, making them ideal for small spaces.
  • For added safety, they don’t use an open flame and provide freeze protection if connected to power. 

What size under-sink water heater do you need?

The great thing about under-sink water heaters is that they come in various sizes. It’s relatively easy to find a unit that will fit snugly beneath your sink while still delivering plenty of hot water when you need it most. 

Of course, the specific size you’ll need depends on a few factors – such as how long you will have the hot water running and the available open space where the unit will be located. 

Ultimately, determining which size under-sink water heater is right for you requires assessing your household’s unique hot-water needs and selecting accordingly!

Under-sink mini tank water heater regulations

If you are considering installing such a unit for your home, you must know a few under-sink water heater regulations. The USA regulations for under-sink water heaters may vary depending on the state and local codes, but some general guidelines are:

A licensed professional should install all under-sink water heaters. A DIY installation should always adhere to all local building and plumbing codes.

Under-sink water heaters must have a pressure relief valve connected.

Under-sink water heaters must be properly grounded. All installations should always adhere to all local building and plumbing codes.

Maintenance and care tips for your under-sink water heater

Check the anode rod regularly. 

The anode rod helps protect the tank from corrosion, so it’s important to check it periodically and replace it if necessary.

Flush the tank regularly. 

Over time, sediment can build up in the bottom of the tank, so it’s important to flush it out every few months. 

Keep an eye on the temperature. 

Most under-sink mini tank water heaters have adjustable thermostats, so you can ensure the water is always at the perfect temperature for your needs. If you notice the water isn’t as hot as it used to be, or if it starts fluctuating in temperature, call us.

Keeping your gas tankless water heater unit in top shape with regular maintenance

If you’re the proud owner of a gas tankless water heater unit, you know it can significantly reduce your energy bills and provide an endless hot water supply. 

However, did you also know that regular maintenance is crucial for optimal performance? 

Unfortunately, many homeowners skip this step or delay it until there’s a problem. 

So today, we’ll explain why neglecting your gas tankless water heater unit’s maintenance could lead to costly repairs and jeopardize your safety. 

Why is regular maintenance important for a gas tankless water heater?

First, it helps prevent the build-up of sediment and scale in the unit, which leads to decreased efficiency and performance over time. 

Additionally, regular maintenance can help extend your unit’s lifespan by keeping it in good working condition.

What is regular maintenance of gas units?

To ensure your gas unit is operating properly and efficiently, it is important to maintain it regularly. 

During your monthly inspection, you should check all connections for leaks. For gas connections, the best way to do this is to use a soapy water solution; if bubbles are present, there is a leak. Be sure to tighten or replace any faulty connections. 

You should also inspect the venting system to ensure it is not blocked or obstructed. 

If you live in an area with hard water, flush your gas unit about once every quarter. 

Are there any safety concerns you should know about with a gas tankless water heater?

Yes, it’s important to note that tankless units produce exhaust gases, which can be dangerous if not properly vented. 

Ensure you have your unit installed by a qualified technician and that it is properly ventilated to prevent any hazardous build-up of exhaust gases. 

Additionally, always follow the manufacturer’s instructions when performing any maintenance on your unit.

Overview of venting

The venting installation is responsible for drawing the fumes out of your tankless water heater and exhausting it outside. 

Over time, lint and other debris can build up in the vent, restricting exhaust, and causing your unit to work harder than necessary. 

A clogged duct exhaust can also lead to premature failure of your unit. 

Requirements for proper venting

There are a few key requirements for venting tankless water heaters that must be met to ensure optimal performance and safety. It must be: 

  • made of non-combustible material, such as stainless steel or galvanized steel and aluminium. 
  • sized correctly for the specific model of tankless water heater being used.

Water quality matters: tips for improving the lifespan of your tankless water heater

Did you know that the lifespan of the tankless water heater can be greatly affected by the quality of your home’s water supply?

Over time, mineral buildup and sediment accumulation can lead to corrosion, leaks, and even premature failure of this essential appliance. 

But fear not! 

In this article, we’ll share some tips on how to improve your water quality and extend the life of your tankless water heater. 

What is hard water and scale? 

Water high in mineral content, such as calcium and magnesium, is called hard water.

Signs of poor water quality

  • Water that looks cloudy or discolored
  • Water that smells bad
  • Water that tastes bad
  • Water that leaves deposits on fixtures or appliances

What is hard water on the pH scale?

The pH scale is a measure of how acidic or alkaline water is. The pH scale ranges from 0 to 14, with 7 being the neutral point. Readings below 7 indicate acidity, while readings above 7 indicate alkalinity.

Hard water has a high mineral content, which makes it more alkaline. The higher the mineral content, the higher the pH reading. 

Effects of hard water on a tankless water heater 

Hard water can have several negative effects on tankless water heaters

The most common issue is scale buildup on the heat exchanger’s surfaces. This scale can insulate the heating surfaces, causing them to work less efficiently and eventually fail prematurely, it can damage temperature sensors causing fluctuation in water temperature or production of temperatures too high or too cool.. It can also damage temperature sensors causing fluctuation in water temperature or producing temperatures too high or too cool.

In addition, hard water can also clog pipes and reduce the flow of hot water to your taps. It can also reduce needed water pressure or flow to start the water heater.

What can you do to reduce the hardness of your water?

Install a sediment & hard water filter: This will help remove impurities from your water supply, extending the life of your tankless water heater.

Use soft water: If you have hard water, consider using a water softener to extend the life of your tankless water heater. 

Drain and flush regularly: Draining and flushing your tankless water heater regularly, at least once a year, helps remove the buildup from the heat exchanger, which can lengthen its lifespan.

Flushing tankless water heaters 

Flushing your tankless water heater is a relatively simple process you can do yourself.

You can view the process below:

What you’ll need: 

  • About 3 gallons of distilled (household) white vinegar. 
  • 2 approximate 5-gallon or bigger buckets. 
  • A circulation pump. Although you can flush your tankless water without one, it won’t be as thorough, and you’ll have to take the water heater off the wall.
  • These pumps usually come with their own pipes, but two pieces of garden or washing machine hoses are just as effective.

Flushing steps:

  1. Turn off the power (electricity and gas) to your tankless water heater. 
  2. Close the main shut-off valves on hot and cold-water lines.
  3. Open the flushing valves on both the hot and cold-water lines. 
  4. Open the valves on top of each manifold. Once you open the valves, the water in the tank will run out, so keep your bucket underneath them. 
  5. Clean the prefilter.
    1. It’s normally located outside the unit, above the cold-water valve, but consult your user manual if you are unsure of where it is. 
    2. Simply open it and wash the filter clean with water and maybe a small toothbrush. 
    3. Once clean, put it back.
  6. Connect one of the hoses to each flush valve (one for hot and one for cold). 
  7. Connect the open end of the hose connected to the cold-water flush valve to the pump’s outlet.
  8. Put the pump and the open end of the other hose (hot) in the bucket.
  9. Pour the vinegar into a bucket, ensuring that the pump and the open end of the hot-water line are submerged. 
  10. Plug your pump in to start it up. 
  11. Let the cleaning solution circulate for at least 45 minutes, up to an hour.
  12. Once it’s done, shut the pump off.
  13. Close the valves on top of each manifold, remove the hoses, and close the protective caps tightly on the flushing valves. 
  14. You can clean the prefilter again to ensure no new debris gets stuck.
  15. You can empty your bucket in the garden. 
  16. Open the hot water faucet connected to the tankless hot water heater and let the water run to purge air from lines and fill the heat exchanger.
    1. The hot water won’t run while the main valves are still closed.
  17. Open all the supply valves and turn the gas line or power  back on. 
  18. Turn the tankless water heater back on.
    1. Some air bubbles will come out of the faucet as the tankless water heater runs; that is perfectly normal.
  19. Now you are ready to enjoy clean and clear hot water for another year.
