All Saint's Church
Kingston Seymour
North Somerset

The original heating installation was most likely installed in the latter part of the Victorian period or early Edwardian.

This time period can be confirmed from the type of radiator installed. All the radiators in the Church are
Haden of Trowbridge manufacture, who had their own iron foundry (1874 – 1905) in the town of Trowbridge.


The heating system was designed as a LPHW open system with a F&E tank originally using gravity circulation for the
pipework distribution. T
he boiler located in an external basement room was a solid fuel fired cast iron sectional pattern.

Pipework installation

The installed pipework is an unusual arrangement that used a mixture of cast iron and steel tubing with
long sweep pulled bends and cast iron bolted flanges.
The pipework distribution system designed to operate using gravity circulation, comprised
two one-pipe single loop circuits, one either side of the Nave.

At a later date pipework both circuits were cut into with a reduced size section inserted and a wheel gate valve fitted.
This could have occurred when the system was converted to pumped circulation and some form of water balance
was needed to regulate the flow rate in the two circuits.


The pipework shown above sets up to a higher level with both radiators supported on purpose made cast iron pedestals. These pedestals
were most likely made at Haden's foundry. This increased pipework height can be assumed to have assisted the gravity circulation.

The pipework shown comes from an age before malleable pipe fittings (bends, tees and unions) had been invented, so pipework
only comprised a selection of wrought iron 90 elbows, pulled bends and longscrew connectors. All these different fittings are
shown in the layout of the above pipework. The flow pipework is routed directly through each radiator with BOE connections.

On either side of the Nave a purpose made cast iron twin fitting has been installed to fix the flow and return pipes and allow for
thermal expansion of the pipework. These cast iron fittings were most likely cast in Haden's Trowbridge iron foundry 

Fender sets have been used to route the pipework around the main columns of the Church.
Fitting them to the radiator must have proved a difficult installation.


Note the cast iron pedestals under the feet of the radiator
probably cast in Haden's foundry

The original boiler
was located in an external
basement room and was a cast iron sectional pattern.

At a later date the cast iron
boiler was abandoned and
the basement room filled in.

The current boiler installed
in the late 1970's is a steel
cased welded pattern fitted
with an oil burner.

Both the cold and and open
vent pipes connect direct
into the boiler.

A small Grundfos circulating
pump is fitted in the main
flow pipe.
