Surely the battery is only the power source for the spark to initially
light the pilot. Once lit it's the thermocouple that provides the power
to keep the valve open

The oxypilot will be £40-50 to buy and not a fiver as an
earlier post.

An oxipilot appears to just be an assembly that contains a thermocouple,
a pilot jet and a (spark) electrode.

Its only an individual thermocouple that has been quoted as a fiver.


Oxypilots are a calibrated pilot assembly specific to that
appliance.

What do the manufacturers calibrate? It just appears that the one piece
replacement containing 3 separate items is functionally no different to
what has previously fitted to boilers for many decades that didn't
require any calibration other than the correct physical positioning to
get the thermocouple tip in the flame.

For the professional gas technician replacing all items as a combined
unit may be cost effective as it could cure 3 potential different
"faults" in one go and most of the cost will be the call out and labour.

What the manufacture may have done in a Oxypilot is to make the whole
pilot assembly it cheaper to manufacture by crimping components to a
bracket rather than using screws/nuts and hence making it difficult or
impossible to disassemble.

Get a second opinion as it may well be something and nothing.

Wouldn't the second opinion be based on the same educated guesses and
any home visit to do otherwise cost the OP money probably to the amount
previously quoted?
