I guess the main attraction would be less space lost in a kitchen, and
less noise.

A disadvantage could be any heat lost from the boiler itself,
especially in the winter, if there was no need to heat the outbuilding
(other than for it's own frost protection)?

The only heating my Mum has in her kitchen is the boiler

Most boiler casings are internally in contact with outside air at
outside temperature. If sited in a kitchen they likely become a sink of
kitchen warmth.

and the oven
/ stove if on and the flow / return pipes 'passing though' [1]. ;-)

I've not felt the need to heat kitchens unless they're a kitchen-diner.
