Home Inspection of Hot Water Boilers
Overview of Hot Water Boilers Hot water boilers have been used for decades and can be found in both old and newer homes. The primary difference to a common gas or electric furnace is that water is heated and distributed throughout the home in pipes and radiators instead of forced air flow. The heat source is typically electric, oil, wood, gas or propane and may include supplemental solar heating.
Modern boilers in Canada are high efficiency and often used beyond heating just the rooms inside your home. Pipes can be laid to distribute heat in garage floors, pools, driveways and outbuildings.
How Hot Water Boilers Work
While a forced air electric or gas furnace circulates heated air through your home, a boiler provides radiant heating. Heat from the water/steam heats up the objects in each room through radiation instead of convection. This takes longer to completely come up to temperature but results in a longer lasting warmth.

Like any heating system, regular maintenance and inspection is recommended to ensure everything is operational and reliable. Your boiler may stop working for a number of reasons. One of the components could fail such as sensors/controls, pump or valve. A leak or air in the closed water system may cause a pressure loss and the system will not flow, if this occurs have the system serviced, it may simply require the lines to be bled.
