Understanding the Difference Between a Boiler and a Water Heater
Boilers heat water to warm your home through radiators, baseboards, or in-floor systems. Some models, like combi-boilers, also provide domestic hot water. Water heaters, on the other hand, supply hot water only for showers, dishwashing, and laundry. Knowing these distinctions helps Calgary homeowners select the right system for their needs.
Types of Boilers and Water Heaters
Both boilers and water heaters have their own different types. Let’s go over them quickly.
Boiler Types for Calgary Homes
Boilers come in several types suitable for Calgary conditions:
- Hydronic Heating Boilers: Circulate hot water through radiators and baseboards for even warmth.
- Steam Boilers: Heat water to create steam for heating systems (less common in modern homes).
- Combi-Boilers: Provide both home heating and domestic hot water in a compact, wall-mounted unit.

Water Heater Types
Water heaters are also available in multiple options:
- Tank Water Heaters: Store hot water in a tank for immediate use.
- Tankless Water Heaters: Heat water on demand, saving space and energy.

Benefits of Boilers in Calgary Winters
Boilers provide reliable, whole-home heating, essential for Calgary’s harsh winter climate. They distribute heat evenly, work quietly, and can integrate with various systems like in-floor heating or baseboards. Combi-boilers also provide hot water, reducing the need for a separate water heater and saving space in utility areas.
Benefits of Water Heaters
Water heaters provide consistent domestic hot water for showers, laundry, and kitchen use. Tankless models save energy by heating water only when needed, while traditional tank water heaters store a ready supply. They are ideal for homes where whole-home heating is already provided by a furnace or boiler.
Choosing the Right System for Your Calgary Home
When selecting a system, consider:
- Home size: Boilers suit larger homes or homes with multiple levels; water heaters suffice for smaller households.
- Heating needs: Boilers provide both space heating and hot water, while water heaters only provide hot water.
- Energy efficiency: High-efficiency boilers and tankless water heaters reduce utility bills over time.
- Installation space: Combi-boilers and tankless units are compact, ideal for condos or smaller utility rooms.

Maintenance Tips for Boilers and Water Heaters
Proper Maintenance for Boilers and Water Heaters
Proper maintenance is essential to extend the lifespan of your heating systems and ensure they operate efficiently. Annual boiler inspections should include checking burners, venting, and pressure settings. Water heaters should be flushed yearly to prevent sediment buildup, and thermostats, pressure valves, and safety systems should be routinely checked. Trust certified technicians like Comfort Union to perform these services, keeping warranties valid and your systems safe.
Common Issues and Warning Signs
Of course, boilers and heater both have finite lives. These two systems will also have problems that differ from each other so let’s talk about them here.
Boilers
Homeowners may notice short cycling, uneven heating, low water pressure, or unusual noises, all of which indicate potential problems.
Water Heaters
Leaks, insufficient hot water, or rumbling noises caused by sediment buildup are common warning signs.
Detecting these issues early helps prevent costly repairs and ensures consistent comfort throughout Calgary winters.
