Designing for underfloor heating efficiency

About this CPD

With heat pumps and low-temperature systems becoming standard, the performance of the screed sitting above the pipework is critical. This CPD looks at how thermal conductivity, screed thickness and contact area combine to determine system response time and running cost.

We cover live worked examples comparing typical floor build-ups, including the implications for Part L and the upcoming Future Homes Standard.

Learning outcomes

• Quantify the impact of screed conductivity on heat pump efficiency.
• Specify the correct cover depth for low-temperature systems.
• Compare typical anhydrite vs cementitious build-ups for UFH.
• Avoid the most common detailing mistakes around manifolds and movement joints.
