My favoured place would be in
the loft at the gable end.
Loads of unused space, close to
bathroom and toilet, directly above the
kitchen, and I can use the gable end
or the roof for a vent.

Sounds good. More hassle but if you can get it through the roof, much
neater.

Closest suggestion so far is Jeff's Alpha CD50.
Any known problem,s with this unit, or good
alternatives (Jeff, close your eyes at this point
since you have already bought one and don't really want
to know)?

Excellent choice. 5 year guarantee. and a highflow rate that fills a bath
very quickly. Will do two simultanteous showers. Look at the other boilers
I mentioned. They are all wall mounted units. In the loft they can be on a
Unistrut frame off the rafers, so no need to actually be on the gable end.
There are also high flowrate floor mounted units that give excellent
flowrates. The Potterton Powermax breaks down so it can be lifted into the
loft. Make sure it is well supported on the loft though. The Viessmann 333
is a floor mounted job and of RR class. You get what you pay for.
