What is a Boiler?
Many people might think a boiler and a water heater are one and the same. After all, they both heat water throughout your house. However, when it comes to boiler service in Calgary, it’s important to understand that a hot water tank vs. a boiler serve different purposes within the home.
While a water heater (either tanked or tankless) heats up cold water and pumps it throughout your home when you turn on a tap to wash or drink, boilers turn water into steam for heating purposes.
Similar to pressure cookers, boilers work by creating an airtight seal to increase the boiling point. This allows water to heat up faster, creating steam that can be used for various processes or applications. In the context of your home’s boiler, the steam is used to heat your home with radiant heat.
A gas burner or electric heater warms up supplied water. Once the water turns to steam, it moves the heat through the home. Steam is a great heat carrier and is lighter than water, so it’s an inexpensive and efficient way to transport heat.
After the heat has been dispersed throughout the home, the steam cools, turns back to water, and re-enters the boiler to be heated again. Most boilers are on a closed loop system, which means the water and steam are recycled during the process.

Common Boiler Issues
If your boiler system is getting old, or if maintenance has been neglected, you might notice some common problems popping up. You may be able to fix some of these issues yourself, but it’s best to leave the more involved and difficult repairs to Knight’s team of certified experts.
- Broken parts can cause leaks or prevent the water from heating properly
- Inaccurate of faulty thermostats can cause the boiler to randomly turn on and off
- Strange noises such as whistling, banging, or gurgling might indicate air in the system, low water pressure, restricted water flow, or imminent part failure
- Mineral, lime, or sludge buildup which reduces water flow and causes malfunctions
- Low water levels or pressure might indicate a pressure valve needs to be replaced
- No heat might mean failed parts or inadequate water levels
- Leaks or drips are often caused by worn-out seals, corrosion, or broken parts, and can lead to rusting
- Natural gas issues like the pilot light going out, broken thermocouples, drafts, or built-up deposits.
- Frozen condensate pipes might need to be de-iced
