Knock Basilica

Radiant Panels

As the ceilings in the Basilica are so high, and with such a vast space to heat it was deemed necessary to install LPHW (Low Pressure Hot Water) Radiant Panels.

Our client explained that during the wintertime in particular, cold discomfort issues were experienced within the chapel areas by the parishioners and visitors. In light of the very high ceilings of up to 30 meters high and the large space within the Basilica, such a building could prove difficult to heat.

The design brief showed a number of curved false ceilings which presented its own challenges. Versatile and Zehnder needed to come up with a LPHW solution to this specific project.

Heating Solution

The original Basilica was completed in 1976 and a total refurbishment has now been completed. The Basilica, which can accommodate approximately 10,000 people, serves the Roman Catholic Archdiocese of Tuam and it is part of the Knock Shrine grounds incorporating four other churches.

The overhaul involved a full internal fit out to include some structural adjustment to permit circulation along the center of the space. The existing air handling system could not heat the space to that of a comfortable temperature. Unit heaters were considered but as the ceilings were so high and heat rises it was decided that it would not be the most economical solution. IN2 asked Versatile if we could provide a LPHW radiant solution, to be integrated in the ceiling to heat the space. LPHW Radiant panels were the preferred choice for this project as radiant panels do not heat the air, they heat the surface it reflects on and in turn, that surface acts a radiant panel.

This heating and ventilation solution provides long term cost savings and provides an enhanced environment for parishioners along with the vast number of pilgrims and visitors each year.

Each section of the Basilica has a number of curved ceiling sails which integrates our bespoke radiant panel, this contributes to the absorption of noise.
