Maintaining the Efficiency of Your Underfloor Heating

Underfloor heating offers an efficient alternative to traditional heating systems. Its growing appeal lies in its ability to provide consistent warmth and comfort, making it a preferred choice for many. However, maintaining the efficiency of these systems is crucial to ensure they function optimally and economically.

Underfloor Heating:

Underfloor heating operates by evenly distributing heat across a floor area, making it more efficient than traditional radiators that heat from one point. Two main types exist: electric, using heating wires, and water-based, using pipes carrying hot water. Several factors influence the efficiency of these systems:

Insulation:
Proper insulation is critical. It prevents heat loss, ensuring more heat stays within the room, thus improving efficiency.

System Control:
Effective control systems, like thermostats, are essential for managing heat output and maintaining consistent temperatures.

Installation:
Correct installation impacts efficiency significantly. Factors such as the type of flooring and the positioning of heating elements play a crucial role.

Routine Maintenance

Regular servicing and checks are vital for maintaining the efficiency and longevity of underfloor heating systems.

For Wet Systems:

  • Bleed annually to remove air and improve efficiency.
  • Check and adjust boiler pressure regularly.
  • Inspect pipes and connections for leaks.

For Electric Systems:

  • Regularly inspect heating elements and wiring for damage or wear.
  • Test the thermostat and controls to ensure accurate temperature regulation.
  • Keep the area around heating elements free of debris and obstructions.

Thermostat

Optimising the use of thermostats is crucial for enhancing the efficiency of underfloor heating systems. Key practices include:

  • Adjust the thermostat to a comfortable but energy-efficient temperature, typically between 18°C to 21°C.
  • Lower the settings slightly in warmer months and increase during colder periods to maintain efficiency without overheating or overcooling.
  • Utilize programmable thermostats to set heating schedules, reducing energy usage when the house is empty or during night hours.
  • Ensure the thermostat accurately measures room temperatures and recalibrate if necessary.

Annual System Health Checks

Annual inspections are critical for ensuring the integrity and efficiency of underfloor heating systems. The checklist for these inspections includes the following:

  • Inspecting Manifolds:
    Check for leaks or damage to ensure proper flow and distribution of heat.
  • Boiler and Pump Assessment:
    For wet systems, ensure the boiler and pump are functioning efficiently and are properly maintained.
  • Thermostat and Control Checks:
    Verify that thermostats and controls are accurately responding and functioning.
  • Visual Inspection of Heating Elements:
    For electric systems, inspect the elements for any signs of wear or damage.
  • Pressure and Flow Tests:
    Conduct tests to ensure the system is operating at optimal pressure and flow rates.

Preventing Efficiency Loss

To maintain underfloor heating efficiency:

  1. Avoid Obstructing Heat Sources:
    Keep furniture and rugs away from heat elements to allow unobstructed heat distribution.
  2. Monitor System Pressure and Flow:
    Regularly check the pressure in wet systems and ensure even flow across heating elements in electric systems. Correct pressure and flow ensure the system operates efficiently and effectively.

Additional Maintenance

  1. Flushing and Balancing:
    Periodically flush water-based systems to remove debris and rebalance to ensure even heat distribution. This improves system efficiency and lifespan.
  2. Using Inhibitors:
    In wet systems, use inhibitors to prevent corrosion and scaling, which can hinder system performance.
  3. Inspecting Manifolds and Valves:
    Regularly inspect manifolds and valves in both types of systems for signs of wear or damage, which can affect system efficiency and safety.
