Unusual Boilers

When any historical heating system is refurbished, the first and most likely
item of equipment to be removed, replaced and then usually destroyed
is the boiler.
Therefore, it is a very rare occasion for the Heritage Group
to find or alternatively, be informed about an early example of a Victorian
tubular boiler. To date only two examples of vertical
tubular boilers have
been discovered and photographed

Three different patterns of the upright
boiler as displayed in catalogues.


When ground works excavations were being
carried out for the new
foundations being
constructed for a building
in Ripon Yorkshire,
it exposed an old firing pit, and an upright
tubular boiler was unearthed and discovered.

The cast/wrought iron tubular boiler sits on
a foundation ring which has an open base
that allows the flames from the furnace
chamber underneath to heat the water in
the tubes. The top of the boiler has a
circular opening allowing the flue gases
to exit through a suitable chimney.

In picture 2 the firing door can be seen.
The ash or clinker was removed through
the opening which can be seen at the
bottom of the pit.

In picture 1 note the boses for the flow
and two return pipework connections. 








When builders were carrying out renovation work to a basement room of a residential Victorian villa
in Bath Spa, they started to clear away a
brickwork enclosure in one corner of the room only to find
that it housed
an old cast iron upright tubular pattern pipework boiler. The Heritage Group were
contacted and asked
to visit and identify this historical equipment. The firing and ash clean-out doors
can be seen in pictures 1 & 2.
A section of both the flow and return pipework from the boiler has been
cut-out but their alignment with the high level pipework can be easily matched in picture 4.
