Infloor heating & installations

Hydronic infloor heating, also known as radiant floor heating, is a popular heating method that uses warm water circulated through pipes embedded in the floor to provide even and efficient heating throughout a space. This system can create a comfortable indoor environment, with the heat rising gently from the floor and warming occupants and furniture.

​

Key Components of Hydronic Infloor Heating:

1. Piping System:
   - Typically made from materials such as PEX (cross-linked polyethylene) or copper.
   - The pipes are laid out in specific patterns (e.g., serpentine or spiral) to ensure even heat distribution.

2. Heating Source:
   - Usually a boiler or a water heater that heats the water before it's sent through the pipes.

3. Circulation Pump:
   - Moves the hot water from the boiler to the piping and back, maintaining consistent flow.

4. Thermostat or Control System:
   - Allows you to set and regulate the desired temperature in the space.

Insulation Underneath the Piping:

Insulation is a crucial component of a hydronic infloor heating system, as it enhances efficiency and performance by:

1. Preventing Heat Loss:
   - Insulating the subfloor helps prevent heat from dissipating downwards, ensuring that more heat is directed upward into the living space. This improves system efficiency and reduces energy costs.

2. Improving Response Time:
   - A well-insulated floor can help the system reach the desired temperature more quickly and maintain it more effectively.

3. Reducing Condensation:
   - Proper insulation can help to minimize condensation and-related issues, particularly in climates with significant temperature fluctuations.

 

Types of Insulation Used:

1. EPS (Expanded Polystyrene):
   - Commonly used due to its high insulation value and moisture resistance.

2. XPS (Extruded Polystyrene):
   - Offers similar benefits as EPS but is more rigid and has a higher compressive strength, making it suitable for various applications.

3. Reflective Foil Insulation:
   - Often used in conjunction with other insulation types, it helps reflect heat upwards.

4. Cementitious Underlayment:
   - Sometimes incorporated for adding weight and thermal mass, this material can help retain heat longer.

Installation Considerations:

1. Floor Type:
   - Different flooring materials (tile, wood, carpet) will have varying levels of efficient heat transfer. Tile, for instance, is excellent at conducting heat.

2. Pipe Spacing:
   - The distance between the pipes can affect heating performance. Closer spacing generally leads to more uniform heat distribution.

3. System Design:
   - It's essential to properly calculate the load requirements and layout the system according to the specific needs of the space being heated.

4. Air Leakage:
   - Sealing any gaps or cracks in the subfloor or foundation will help improve the overall effectiveness of the insulation and heating system.

In summary, hydronic infloor heating is an efficient and comfortable method of heating spaces. The addition of insulation underneath the piping enhances performance by minimizing heat loss, improving response times, and increasing overall system efficiency. Proper installation and design are crucial to optimize the benefits of both the heating system and the insulation.
