High Ceilings

Traditional convection heating relies on warm air rising, reaching the ceiling, cooling, and then descending, creating a convection current that gradually heats a room. However, this process becomes inefficient in high-ceilinged structures like churches, where a substantial portion of the heat dissipates through the roof.

In contrast, underfloor heating emerges as the optimal solution for buildings with lofty ceilings. Its radiant heat nature concentrates precisely where occupants are situated, enhancing efficiency and comfort. By strategically distributing heat from the ground up, underfloor heating eliminates the drawbacks associated with conventional convection systems, ensuring a more effective and targeted warmth that is especially beneficial in spaces with soaring ceilings, such as churches.

Radiant versus Convective

The consensus reached at the “The Future of Heating in Historic Buildings” conference held in London in 2022 was clear: “where feasible, underfloor heating stands out as the optimal solution for heating churches.”

When it comes to installing underfloor heating in a church, two primary methods are commonly employed:

  1. Installation on the Existing Floor: This involves placing the underfloor heating system on the existing floor, which results in a slight elevation of the floor level.
  2. Full Excavation: Alternatively, a comprehensive excavation approach is adopted, preserving the existing floor levels while integrating the underfloor heating system.

These two methods offer flexibility to cater to the diverse structural needs of historic churches, allowing for a tailored and effective application of underfloor heating technology.
