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.

Benefits of Installing a Boiler

Boilers use hydronic radiant heating rather than forced air. This means your home will be evenly heated in every room, so you can say goodbye to cold drafts, sweltering top-floor bedrooms, and freezing basements. 

Radiant heating allows you to zone temperatures and control the feel of each part of your home. You can also install in floor heating, giving you warm kitchen and bathroom tiles that are a treat on cold winter mornings.

Boilers are one of the most simple yet efficient heating systems you can find. Unlike forced air systems that have motors and blower fans, boilers only have one major mechanical moving component—the circulator pump. 

What this means is that a high efficiency boiler uses less energy and stress in order to function. Heat pumps can last around 10-15 years, and furnaces typically last 15-20 years. Boilers, however, can last up to 30 years when properly maintained!

Forced air systems blow air around your home—but also blow dust, allergens, and pet fur. If anyone in your family suffers from asthma or related breathing issues, it can be aggravated any time the furnace switches on. 

Radiant hydronic heating won’t kick dust around your house, nor will it decrease humidity by drying out the air in your home. Calgary residents are all familiar with the struggle of dry air, which can cause nosebleeds, headaches, and chapped, dry skin.

It’s also much quieter than a furnace, so if you have light sleepers or simply value a zen-like space, you won’t have to worry about draft noises or any furnace units banging awake when they turn on.

Despite a higher upfront cost, boilers actually cost less to run over time than a furnace. Offering lower heating bills, controlled humidity levels, and consistent heat throughout your home, it’s a great option to consider if you’re looking for a heating system with maximum efficiency.

Water does an amazing job of transferring heat, and is a much more efficient way of moving heat than air, so you don’t have to use as much energy to heat your home. Not only will that save you money on your monthly bill, but the simple mechanics and long lifespan of a boiler will mean you’ll have to spend less on maintenance, repairs, and eventual replacement.

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
