Also known as hydronic heating, this system uses heated water from a boiler or heat pump to distribute warmth through pipes beneath the floor. The water is heated to a low temperature and circulated through a network of pipes to evenly heat the room. This type of underfloor heating is more commonly used in large or whole-house heating systems, as it requires a separate boiler or heat source.

2. Electric Underfloor Heating:

Electric underfloor heating uses electric mats or cables installed beneath the floor to generate heat. This type of system is easier and less expensive to install compared to water-based systems, making it a popular choice for smaller spaces or single rooms. Electric underfloor heating is controlled by a thermostat and can be turned on and off as needed, providing more flexibility and control for homeowners.

Step-by-step Guidelines on How Hydronic Underfloor Heating Works

Step 1: Heat Source:

The first step in the process is to have a reliable heat source, such as a boiler or heat pump. This is where the water will be heated before being circulated through the pipes. This heat source can be powered by gas, oil, or electricity. If you are using a renewable energy source, such as solar or geothermal, it can also be used to power your underfloor heating system.

Step 2: Water Circulation:

Once the water is heated, it is circulated through pipes that run beneath the floor. These pipes are usually made of PEX (cross-linked polyethylene) and are laid out in a serpentine pattern to evenly distribute heat throughout the room. This network of pipes is connected to a manifold, which controls the flow and temperature of the water.

Step 3: Thermostatic Control:

A thermostat is installed in each room with underfloor heating to regulate the temperature. The thermostat measures the air temperature and adjusts it by turning on or off the flow of hot water through the pipes. If the desired temperature is not reached, more hot water will be circulated. This provides a consistent and comfortable temperature throughout the room.

Step 4: Heat Distribution:

As the heated water circulates through the pipes, it radiates heat upward through the floor, warming up the entire room. The warm air rises, creating an even distribution of heat from the ground up.

This form of heating is more energy-efficient compared to traditional methods, as the heat is evenly distributed and does not escape through ceilings or walls. This also results in a more comfortable and consistent temperature throughout the room.

These are the basic steps involved in how hydronic underfloor heating works. Understanding this process can help you make an informed decision when choosing the right type of underfloor heating for your home.

With its efficient and comfortable heat distribution, underfloor heating is a great option to consider for any modern home.  So, if you are looking to upgrade your heating system or are building a new home, why not consider underfloor heating and enjoy the many benefits it has to offer?  Happy heating!
