It's interesting how everyone has immediately assumed that it's a gas
boiler rather than an oil-fired one and hence is making references to
Corgi registration.


So who certified the oil fired boilers when Corgi existed?

A good question. Did Corgi certify non-gas boilers as well as gas ones? Were
they also familiar with oil-related regulations and plumbing regulations
such as size of expansion vessel (in lieu of header tank to accommodate
expansion)?
