I'm looking to buy a 20Kw, wall mounted , condensing, gas boiler, balanced
flue through bungalow roof.
I would prefer to have the feed, return and gas pipes located at the bottom
of the boiler as it's more convenient for connecting to the valve and airing
cupboard cylinder which is located behind the wall.
A corgi registered friend who lives across the road says that all the
boilers he knows about have the feed and return located at the top of the
boiler.
Does anyone know of a condensing boiler where the feed and return are
located at the bottom? or is there a good reason why they should be located
at the top? e.g, in the case of pump failure hot water rises?

I wouldn't let your neighbour anywhere near a gas appliance then - I
can't think of a single wall mounted boiler which ISN'T bottom fed
