Grade II listed church, North London

9 Apr 2019
Case study

Potterton Commercial and specialist church contractors Christopher Dunphy Ecclesiastical Limited took a creative approach to installing a modern heating system at St John’s Church in Friern Barnet, hoisting new condensing boilers up through a hidden roof hatch days before the Christmas festivities. 

The nineteenth century church encountered issues with its heating system after its old non-condensing section boiler – located in a basement plant room – failed just two months before its busiest time of the year.

The new plant location meant that two efficient Potterton Sirius Two WH 110kw condensing boilers could be installed using the Sirius Two cascade and pipework header kit, helping to ensure more cost effective heating well into the future. 

The new system was installed in half the usual time so that the equipment was up and running in plenty of time for the Christmas Eve service.
