Troubleshooting

Aluminium is highly conductive and should heat rapidly. If it is slow:

• Check Air Locks: ThermaSkirt requires bleeding just like a radiator. Ensure all air is expelled via the bleed valves located at the return connection points.
• Pump Speed: Due to continuous looping, ThermaSkirt resistance can be higher than standard systems. Increase the modulating pump speed slightly.
• Flow Orientation: Ensure hot flow enters the TOP pipe of the skirting and returns via the BOTTOM pipe. Reversed flow ruins thermal dynamics.

As aluminium expands rapidly with heat, thermal expansion noises can occur if installed too tightly.

• Expansion Gaps: Ensure you have left a 2-3mm gap behind corner covers and connecting covers to allow the alloy profile to travel horizontally as it heats up.
• Bracket Tension: Ensure the brackets are screwed flush, but not severely overtightened causing the profile to bite into the plastic.
• A light spray of PTFE dry lubricant along the bracket track can resolve persistent expansion friction.

If one end of a large room is hot but the far end is cold, the flow rate is insufficient to overcome the heat drop across the loop.

• Manifold Balancing: Use the flow meters on the manifold to increase the flow rate (L/min) to that specific circuit. Shut down smaller circuits slightly to force pressure.
• Maximum Loop Length: Ensure you have not exceeded 20 linear metres on a single 15mm loop. Rooms larger than 20m perimeter must be split into two separate manifold circuits.
