Case Studies

All Saints Church

Winter was fast approaching and All Saints Church had a problem – Their oil burning boiler had been condemned.

So, in an effort to save their flock from getting cold, they called in CBS to do an initial survey, where it was discovered that the heat exchanger had cracked. Biblical efforts were made to try and source replacement parts but found they were no longer available.

CBS recommended the Ideal Falcon Boiler with a Riello oil fired burner as a replacement. This was selected because it allowed them to utilise as much of the existing pipework, flue, controls and heat receptors as possible. Not only would this reduce the installation cost, but also was twice as efficient to run, minimising the impact on the collection plate for years to come.

Prior to the installation of the replacement boiler, CBS had to drain down the system and dismantle the condemned unit. The flue was then modified to make it compatible with the new boiler. The system was then flushed to cleanse it of any slime, limescale and sludge which could damage the new boiler.

As the plant room was located in the basement, the new boiler had to be taken down in sections and rebuilt in situ. Once the installation process was under way it was noted that additional ventilation to the plant room would be required in order for the boiler to run at optimum efficiency.

This posed a problem – in order to create extra ventilation, the installation team would normally have to drill through the outside wall to install ductwork, damaging the aesthetics of the building. Fortunately, CBS are well experienced in working on period properties and had a novel solution in mind.

The result was surprisingly simple. The original heating used a solid fuel burner, the heat was then distributed through ducts within the stone work of the church. To prevent the congregation suffocating, small clover leaf shaped air vents were carved into the masonry in both the church and basement, which was now being used as the plant room. CBS were able to utilise these air vents in the basement as ventilation for the boiler. This meant only small vents had to be installed into the door of the plant room, maintaining as much of the character of the church as possible.

Once this small problem was ironed out, the boiler was able to heat the church once again, restoring it to a warm place for praise and worship for all the parishioners.
