Hydronic heating systems are a type of heating system that uses water or a liquid solution to transfer heat throughout a building. Hydronic heating systems are also known as radiant heating systems because they deliver heat through radiant surfaces, such as floors, walls, or ceilings.
Hydronic heating systems are popular in Canada, especially in colder regions, because they offer many benefits, such as:
In this blog post, we will explain the basic components and types of hydronic heating systems, as well as some tips on how to choose, install, and maintain them with the help of a professional HVAC contractor.
Components Of Hydronic Heating Systems
A typical hydronic heating system consists of four main components:
Heat Source
This is the device that generates heat for the system, such as a boiler, a water heater, a heat pump, or a solar collector. The heat source can use various fuels, such as natural gas, propane, oil, electricity, or renewable energy.
Heat Distribution
This is the network of pipes, tubes, or hoses that carry the heated water or liquid solution from the heat source to the heat emitters. The heat distribution can be either closed-loop or open-loop, depending on whether the same water or liquid solution is circulated repeatedly or replaced with fresh water or liquid solution after each cycle.
Heat Emitters
These are the devices that transfer heat from the water or liquid solution to the indoor air, such as radiators, baseboards, fan coils, or radiant panels. The heat emitters can be installed in various locations, such as floors, walls, ceilings, or under cabinets.
The heat emitters can also have different designs, such as finned, flat, or decorative.
Controls
These are the devices that regulate the operation of the system, such as thermostats, valves, pumps, switches, or sensors. The controls can be either manual or automatic, depending on the level of user intervention required.
The controls can also be either centralized or decentralized, depending on whether the system is controlled by a single device or multiple devices.
Types Of Hydronic Heating Systems
There are many types of hydronic heating systems, depending on the configuration and combination of the components. A suitable type of water heating system is installed on the basis of the specific requirements of the business or homeowner.
Some of the common types of hydronic heating systems are:
Baseboard Hydronic Heating Systems
These systems use baseboard units as heat emitters, which are installed along the walls near the floor. The baseboard units consist of copper pipes with aluminum fins that radiate heat to the surrounding air.
The baseboard units are connected to a boiler or a water heater as the heat source and are controlled by thermostats in each room or zone. They are easy to install and inexpensive, but they can take up wall space and interfere with furniture placement.
Radiant Floor Hydronic Heating Systems
These systems use radiant panels as heat emitters, which are installed under the floor surface. The radiant panels consist of plastic or metal tubes that carry heated water or liquid solution and emit heat to the floor and the indoor air.
The radiant panels are connected to a boiler, a water heater, a heat pump, or a solar collector as the heat source and are controlled by thermostats or sensors in each room or zone.
These systems are energy efficient and comfortable, but they can be expensive and complex to install and require compatible flooring materials.
Radiant Ceiling / Wall Hydronic Heating System
These systems use radiant panels as heat emitters, which are installed in the ceiling or the wall surface. The radiant panels consist of metal plates or coils that carry heated water or liquid solution and emit heat to the ceiling or the wall and the indoor air.
The radiant panels are connected to a boiler, a water heater, a heat pump, or a solar collector as the heat source and are controlled by thermostats or sensors in each room or zone.

Tips On Choosing, Installing, & Maintaining Hydronic Heating Systems
If you are considering installing a hydronic heating system in your home or building, here are some tips to help you make the best decision:
Consider Your Requirements
Consider the size, layout, design, and insulation of your space, as well as the climate, fuel availability, and utility costs in your area. Compare the advantages and disadvantages of different types of hydronic heating systems, and consult with a professional HVAC contractor to determine the most suitable option for your situation.
Consider Your System
Select the heat source, heat distribution, heat emitters, and controls that match the specifications and performance of your system. Look for components that are energy efficient, durable, compatible, and easy to operate and maintain.
Check the ratings, certifications, and warranties of the components, and follow the manufacturer’s instructions and recommendations.
Professional Installation
Hire a qualified and licensed HVAC contractor to install your system and obtain the necessary permits and inspections from your local authorities. Ensure that the system is installed according to the codes, standards, and best practices in your area.
Test the system for leaks, pressure, temperature, and functionality before using it.
Regular Maintenance
Perform routine maintenance and repairs on your system, such as cleaning, flushing, bleeding, lubricating, and replacing the components. Monitor the system for any signs of malfunction, such as leaks, noises, odours, or uneven heating.
Schedule annual service and inspection by a professional contractor or engineer to ensure the optimal performance and safety of your system.
