I need to add a new radiator to my house (hallway has none and it's
cold!)

I plan to tap into the CH Flow and Return pipes which already run
underneath there, and plan to use solder ring connections.

My question is this, the access panel for my crawl space is at the
opposite side of the house, so I have to go down beneath the floor and
haul myself along through the rubble to the place where the pipes will
go.

How safe is it to use a blow torch in this confined space? (About 18
inches of verticle space benathe the floors). Apart from the obvious
need to not set the house on fire, I'm more interested in the fumes
given off by the blow lamp. What can I do about those?

I'd rather not use 'speedfix' or compression if I can avoid it, just
for peice of mind.

As somebody else pointed out it'll be a PITA trying to get the pipework
dry enough to solder. However I'm thinking about where you plan to tap
into the existing pipework: is this really the best place to conenct
your new rad in to? I'd be inclined to connect back to nearer the main
'trunk' pipework rather than a branch if possible, to ease balancing.
Maybe you have such pipework more easily accessible under the floor? In
which case I'd run the connections to the new rad in plastic (e.g. Hep2O
or Speedfit) and tap into the existing pipework with pushfit or
compression. Doesn't matter if the run to the new rad involves a few
metres of pipework, and it'll be a lot easier just dragging plastic
pipework under the floor and poking it up through a couple of holes in
the floor than firkling about trying to solder lying flat on your back
in a spider-infested rubble-strewn grave :-)
