Comprehensive Guide to Installing Underfloor Heating Systems (2023)

Underfloor heating systems provide an efficient and comfortable way to heat your home, offering several advantages over traditional heating methods. In this comprehensive guide, we will walk you through the step-by-step process of installing underfloor heating, specifically focusing on electric systems, including heating cable and mesh mat systems. Our detailed instructions will enable you to install underfloor heating seamlessly, ensuring a warm and cozy living space for your family.

Understanding Underfloor Heating Systems

Underfloor heating is a popular choice due to its even heat distribution and space-saving benefits. Electric underfloor heating systems come in two main types: heating cable systems and mesh mat systems. Both systems are suitable for DIY installation, primarily beneath ceramic floor tiles.

Heating Cable System

Heating cable systems involve laying a temperature probe and heating cable on the floor. Afterward, tile adhesive is spread over the cable, and floor tiles are laid on top. A wall-mounted thermostat controls the system. It's crucial to follow the manufacturer's guidelines for wiring and power consumption:

  • Up to 2.2 sq meters (24 sq ft): 300 watts
  • Up to 4.4 sq meters (47 sq ft): 500 watts
  • Up to 10.9 sq meters (117 sq ft): 1,000 watts

Mesh Mat System

Mesh mat systems are easier to install. The heating cable is woven into mesh mats, which are laid directly on the floor. A thermostat connector and temperature sensor are positioned, and the entire system is covered with flexible tile adhesive. The matting should cover approximately 90% of the floor area.

Step-by-Step Installation Guide for Mesh Mat Underfloor Heating

1. Prepare the Area:

  • Turn off the mains supply.
  • Inspect the mesh mat with a digital multimeter to ensure it's undamaged.
  • Plan the position of the Floor Control Unit (FCU) and thermostat on the wall.

2. Lay the Mesh Mat:

  • Apply a 5mm layer of flexible tile adhesive over an area slightly wider than the mesh mat.
  • Unroll the mesh mat on the adhesive, pressing it down firmly.
  • Avoid cutting the cable; unroll the mat in the opposite direction if necessary.
  • Maintain a 50mm gap between the mat edges and walls or fixed objects.

3. Position the Temperature Sensor:

  • Enclose the temperature sensor in an oval conduit and place it in the center of the matting.
  • Secure the conduit to prevent tile adhesive absorption.

4. Make Electrical Connections:

  • Connect the FCU and thermostat to the mains supply following the manufacturer's instructions.
  • Perform an insulation test with a digital multimeter to confirm the mat's integrity.

5. Lay Floor Tiles:

  • Cover the mesh mat with 5mm of tile adhesive.
  • Lay the stone floor tiles following standard tile installation guidelines.
  • Allow the adhesive to set for at least two weeks before using the underfloor heating system.

By following these precise steps, you can successfully install a mesh mat underfloor heating system in your home. Remember to adhere to safety guidelines and consult the manufacturer's instructions throughout the installation process. Enjoy the comfort of your newly installed underfloor heating system, providing warmth and coziness to your living space.
