St. Peters Church, Bury St. Edmunds – Warm Air Heating Installation

St Peter’s Church in Bury St Edmunds

St Peter’s Church in Bury St Edmunds is a warm and inviting church built in a traditional style from flint and brick but perhaps not as warm as it once was because the elderly gas-fired air heating system was becoming unreliable, the two heaters now being obsolete and spares increasingly scarce. It had been very effective and given good service, and we were asked to look at the replacement of the heaters while retaining the basic warm air design.

This wasn’t an easy task as the heating units were squeezed into a small room in the tower above the porch and beneath the bell, so tight that there was virtually no floor left and maintenance had to be carried out while standing on the ductwork conveying the warm air into the nave. Even the ladder into the bell chamber stood on the ducts, and we had to break up the old equipment and ductwork to get it out.

The solution we devised was to replace the old horizontal-discharge heaters by new-generation ones having vertically-downwards airflow.Manufactured by Reznor, they are also ‘room-sealed’ and have a much better operating efficiency and therefore reduced energy consumption, helping to minimise the running costs of the church. The adoption of this type had a further significant benefit as it simplified and reduced the ductwork considerably and had a much smaller footprint, giving better access both to the heating system itself and to the bell
