About Our Calgary Boiler Repair Service

You may be noticing the first signs of boiler trouble, but there's a chance you're seeking boiler repair in Calgary because your unit has completely called it quits. Usually, a faulty boiler will have symptoms that it's going to fail, but we know that in many cases they can be undetectable to the untrained eye. That's where we come in. Our licensed plumbers are trained in detecting boiler issues, and we always recommend scheduling boiler maintenance to stay on top of any that crop up.

Have you been noticing weird noises coming from your boiler, a lack of hot water, leaks, or low pressure? These are all signs you need to get boiler repair in Calgary right away.

A few of the most common issues we handle within our service include:

No Heat or Hot Water

If your boiler delivers both hot water and heat to your home, with a boiler breakdown, there's a possibility that both functions will be lost. This spells disaster for your daily routines, safety, cleanliness, and comfort in your living space, no matter what time of the year it is. There are a handful of reasons why your boiler isn't producing heat or hot water. The most common include:

  • A faulty thermostat that isn't triggering your boiler to heat up. Without this function, there is nothing telling your unit to heat up.
  • An extinguished pilot light. If the pilot light is out, the water inside the boiler cannot be heated. This will prevent your boiler's main function from occurring.
  • Low or no fuel. Gas boilers need ample fuel to operate. Without it, a reaction with heat cannot occur within the combustion chamber, and your water can't be heated. Whether the gas line has been damaged or there is an issue with the supply, this common problem is usually easy to fix.

Hot Water, No Heat

Boilers that are responsible for generating hot water heating and heat have two separate functions. It's possible that one of these functions isn't working due to the malfunction of a part.

For example, the motorized diverter valve controls the flow of water between your heating system and hot water. The valve allows the water to flow to one of these components at a time. If you are not receiving heat, but you are receiving hot water, it may be stuck in one direction. On the other hand, the reason you are not receiving heat may have to do with settings on your boiler or central heating system.


A boiler is a very large vessel that resembles a water heater. In a similar fashion, it holds gallons of water at a time at a certain temperature and releases the water when needed. Due to the large capacity of water held at any given moment, leaks are highly possible–especially in older units. If you have recently noticed a pool of water surrounding the base of your boiler, you should turn off your water supply to prevent the possibility of flooding if your machine decides to burst.

Leaks can occur due to a crack in the tank of the unit, worn-out seals or pressure valves, or corrosion. It is not wise to troubleshoot the cause of the leak on your own. Get in touch with our professional team at first sight.

Low Pressure

Central heating requires pressure to work. If the pressure passing through your hot water system to your heating system isn't high enough, it will not generate any heat. Low pressure is common for older units, but if your boiler is relatively new, this issue may occur due to a leak. If you have noticed any sign of water on the floor around your boiler, the leak is most likely to blame. Small cracks in valves and other components can cause your unit to lose pressure.

Unusual Noises

Boilers aren't the quietest machines in the world, but they aren't extremely noisy either. If you hear abnormal sounds such as whistling, gurgling, or banging, they're a sign that something isn't working correctly inside. Strange noises occur due to restricted water flow when parts begin to loosen, fans are blocked by debris, water becomes too hot, or the electrical components are faulty.

If your boiler sounds like a kettle, limescale has built up on the boiler's heat exchanger. This blocks the flow of water and causes the machine to overheat. In turn, the water will boil, and you'll hear similar sounds as a kettle makes.

Power Problems

Have you noticed that your boiler keeps switching on and off, giving you heat sometimes and none other times? If this problem has persisted for a while, don't leave the working order of your boiler to chance. This is a sign that your unit may be experiencing:

  • Low water pressure. When there is a crack in your tank or a broken seal or valve, your unit will not have enough pressure to generate heat. Cracked tanks are highly dangerous and must be addressed right away.
  • Not enough fuel. If your unit is not receiving the fuel it needs to generate heat, it may switch off. While this issue may be resolved by paying an overdue gas bill, more likely, there is an issue with the gas line.
  • Inadequate water levels. Your boiler has a tank that fills with water. If there is no water in the tank, heating water isn't possible, and the unit may switch off. Since there's no way to see inside your tank, this issue can be quite sneaky.

Rusty Appearance

If you can see rust on the exterior of your boiler, there is likely rust in the interior, too. Rust is a sign of corrosion, and corrosion can lead to leaks. While you may not be experiencing any type of boiler malfunction now, rust is an indication that you will soon. It's better to nip this issue in the bud before it gets any worse. Leaks can cause water damage to your home and may require the replacement purchase of an entirely new unit.

Each of these issues calls for different types of repair, but when choosing our qualified team, you can breathe easy knowing we can handle whatever your boiler throws at us.

FAQs: Boiler Repair in Calgary

What Are the Signs of Boiler Failure?

You've read about a few of the signs of boiler failure already, but many of those issues aren't always easily detectable. While a lack of heat and hot water is an obvious sign, there are many others that are much less noticeable. Be sure to use your senses if you believe something is off with your boiler or furnace.

  • You hear abnormal noises. Boilers aren't quiet, but they do not normally bang, gurgle, or whistle. If you hear any of these violent noises, turn your unit off and call a professional for boiler repair.
  • You smell metallic odours. This may be a sign that your unit is corroded. Corroded boilers may cause your hot water to have a metallic smell.
  • You feel uneven temperatures. This is a sign that your unit may have a leak, a loose seal, or is receiving inconsistent amounts of fuel.
  • You see water around the base of your boiler. Your unit is leaking. Cut off your water supply as soon as you can.
  • You notice higher energy costs. If your energy bills are rising every month, and you don't know why, your boiler could be to blame. To resolve this, regular professional boiler cleaning and maintenance checks are recommended.

Should I Repair or Replace My Boiler?

The decision of whether you get boiler replacement or repair depends on the condition of your unit, its age, and the type of issue it's experiencing. Some issues, such as cracked tanks, call for a complete replacement of the tank. This is quite expensive, and you are better off replacing the entire boiler system.

Similarly, if your tank is corroded, you will need to replace it and all of the parts. Corrosion usually occurs in older boilers anyway, and if yours is more than 10 years old, it's a good idea to upgrade it to a high-efficiency boiler. On average, boilers have a 10-15-year life expectancy. If you're on the fence about repairing or replacing your unit, call us for an inspection or advice on boiler issues.

Is a Boiler and a Water Heater the Same Thing?

While both boilers and water heaters look similar and heat water, they are not the same type of appliance. Unlike water heaters, boilers are also responsible for heating your home. They have two functions instead of one, turning hot water into the steam that provides heat to your central heating or runs throughout your radiant heating system. Do you have a broken water heater? We fix those as well. Feel free to ask us about our hot water tank repair and replacement service.

Can I Fix My Boiler Myself?

Unless you are licensed and trained, you should not take on boiler repair in Calgary. It can be incredibly dangerous, and whether your unit is gas-powered or electric-powered, messing with boiling hot water, electricity, and gas is not a good idea. In fact, boiler repair can be such a safety hazard that if your unit has a crack, is making loud whistling noises, or is experiencing power issues, we recommend shutting off your water supply, calling a professional plumber, and staying away from it.

Is a Broken Boiler an Emergency?

A broken boiler can be an emergency if your home is without heat in the middle of winter and you have children or seniors in your household. We offer emergency boiler repair services for this very reason. If your boiler fails, and you need hot water right away, you can count on our reliable team to arrive quickly and provide a solution.

In the case that you need a new boiler installation, our experienced technicians will work as quickly as we can to order and install the new boiler heating system to make your home safe and comfortable again.

How Do You Know When Your Boiler Needs Replacing?

There are a few key signs to keep in mind to decide whether your boiler needs to be replaced:

  • The boiler is 15 years or older
  • Your utility bills are increasing, demonstrating problems with energy efficiency
  • The blue flame in your boiler has turned orange
  • There is a water leak anywhere on your boiler
  • The radiators are taking longer than usual to heat up
  • There is a foul or bad smell wafting from the boiler
  • Replacement parts are harder to find

As your boiler gets older, the costs of maintaining it and heating your home increase. By upgrading to an energy-efficient boiler, you can save money over time. Connect with our experts today, and they can assist you in determining whether it’s time for a replacement. We aim to make the transition smooth, preventing the urgency of a replacement during the coldest part of winter when your old boiler might fail.
