A Mississauga Tankless Water Heater Repair Service Near You

A tankless water heater also called an immediate, endless flow or on-demand water heater, is energy efficient tankless system that will instantly warm water as it flows through your device. Unlike a traditional unit, they are not able to store any water in the system itself, as they don't have a hot water tank. It only passes through heat exchanger coils instead. They have high thermal conductivity consisting of a choice between copper heat exchangers or stainless steel.

These units can provide a continuous hot water supply from plumbing systems by using heat exchangers that incorporate many lines of parallel plates or tubes. Having a large span of passageways as well as a little inner housing produces a large surface area for a more rapid heat transfer. With so many little components, you know this unit is a big investment and worth the energy savings you gain yearly. But things can still go wrong with it.

Top Reasons You Will Need A Tankless Water Heater Repair Mississauga

Some of the common reasons Mr. Rooter Plumbing receives service calls for this system:

  • No hot water in the home
  • Error message on the unit indicating a problem
  • Customers lose hot water part way through a shower or doing dishes

In an efficient unit, the heat pump houses all the parts to make your on-demand unit work. When it struggles from improper maintenance or overuse, then it may lead to complete system failure. Let's review some of the parts and ways the heat pump could fail.

Mineral buildup:

A buildup of sediment or minerals accumulates and stays inside a system. If your home has iron pipes, it can lead to rust and iron sediment, while areas that with hard water can see scale buildups like calcium and magnesium. Once this happens, it creates a narrow passage for water to flow through and eventually can lead to the system failing.

Overloaded system:

Some assume that it will give them an endless supply of hot water, but every system has its own capacity. Knowing ahead of time how much output your system can handle will help avoid some areas having hot water and others getting cold showers. And in extreme cases, the whole system shuts down, throws the circuit breaker, and crashes.

Flame failure & Ignition Malfunction:

There is a flame and ignition system inside each unit, and if the flame is not lit or the ignition doesn’t fire, it could lead to the unit not heating the water the way it should or at all.

Air supply blockage:

The unit is having issues combusting air or drawing air inside. This usually happens from objects that are too close to the vent system or if there are rodents, wasp nests, or bird nests inside that can block the ventilation.

Exhaust blockage:

Similar to an air supply, the exhaust expels the air out. Checking all vents to ensure they are blockage-free will help the system run smoothly again.

Broken temperature sensor:

The temperature sensor is a signal switch. It tells the system when to turn the gas or electricity supply on or off. If not working, then your water won’t get heated.

Broken thermocouple:

It is part of the pilot burning assembly, connecting to a gas control valve. The gadget inside your unit will sense a flame which then sends gas to the burner, heating your water. When it is broken or malfunctioning, it prevents gas from being delivered when heated water is needed.

Damaged flow sensor:

A flow switch is used to distinguish the existence of water, turning on the unit to heat it as it moves through the piping. Whenever hot water is required, a reed sensor inside the unit will activate and initiate the heating cycle process. When the sensor doesn’t work or is broken, the water passing through will not get heated. Instead, pipes will only cycle cold water.

These are the top parts that could malfunction in your system. Relying on the experts at Mr. Rooter will ensure you can get them repaired quickly and efficiently.

Maintenance Can Help You Avoid A Tankless Water Heater Repair Mississauga

Regular maintenance is key to keeping your tankless model running efficiently and effectively. Neglecting it can lead to issues that shorten the lifespan and increase your energy bills. Here are some tips to maximize your system:

  • Flushing The System: Removal of mineral build-up through system flushing will remove debris and sediment. When it builds up, it works harder than it needs to and then will increase your energy bills. You should flush the system once a year, which helps with energy efficiency.

  • Check the Pressure Valve: The pressure relief valve is an important safety feature preventing excessive pressure. Regular inspections will ensure it is functioning appropriately.

  • Water Filter Inspection: If you have a water filter in your system for hard water or other mineral build-ups, inspecting as well as cleaning filters regularly is highly recommended.

  • Air filter Inspection & Cleaning: The filter can become clogged with dust or debris, reducing the efficiency of the tankless heater. The filter should be inspected and cleaned once a year.

You may think it is an unnecessary expense to hire a Mississauga plumber, and maintenance isn’t needed. But if you look at the average lifespan of your costly investment, it makes sense. When a system has yearly maintenance, and the appropriate parts are cleaned and kept in top shape, then your tankless water heater can last around 25 years. Without proper cleaning and checkups, it will last only ten years maximum. Rely on Mr. Rooter to do your maintenance, giving you peace of mind that your system is in tip-top shape and running smoothly.
