Servicing Hydronic Heating Systems in Toronto

Hydronic heating systems originated in Europe and are becoming increasingly popular in Toronto.


Compared to conventional heating methods, they are superior in heating efficiency and much more flexible. They take into consideration your own home’s heating requirements and how that may vary from room to room.


Heat is distributed through radiators or in-floor pipes. Since there is no fan blowing air through vents in your home, the air is cleaner as well. Forced air can result in more dust and could be an issue for allergy sufferers or those with asthma.

Circulator Pump Repair and Replacement

If you have a hydronic heating system, it’s important to make sure the system is in good working order ahead of the cold winter months. This includes maintenance on the circulator pump as it is the most important component of the system, and essential to keeping your home warm.

Replacing a Circulator Pump


A plumbing professional should always replace a circulator pump and we can help you make the right decision. Different pumps have different flow rates which determine the maximum volume of water than can be circulated at any given head range. That’s the number of feet a pump raises or lowers water at atmospheric pressure. 


Circulators can be cast iron for closed-loop systems, but open-loop systems require bronze or stainless steel pumps to prevent corrosion. Some models offer variable speed functions that vary according to the home’s heating load throughout the day.


Contact Leaside Plumbing in Toronto if you need to replace your circulator pump. We have the necessary expertise to install and maintain the most common brands.

Hearing odd noises, cold radiators?


If you start to hear some odd noises in your home or experience uneven heating throughout your home, this could indicate a problem with the circulating pump.

Radiator Installation and Replacement


We are happy to provide you with an estimate of how much it will cost to replace the radiators in your home with newer technologies. A major benefit of a newer system would be the additional space made available after the installation of smaller low-profile radiators.


Wall-hung radiators are an easy way to update your home. The size, output and finish can be perfectly matched to both the heating requirements and your decor. And not only do they look more modern than conventional cast iron radiators, but they are also more energy efficient too.


Panel radiators are more efficient, heat up faster, and are equipped with smart controls on each unit. Contact us to schedule an appointment with an expert radiator technician. We will be happy to discuss all the available options with you if you’re thinking of replacing your radiators.
