I've noticed these becoming more generally available now ( I know the
electronics industry has a dead line for going lead free and the problems
they are having with it ). Is it the same case as with electronic components
that you need higher temperatures for lead free solder ring copper fittings
and if so will my existing butane powered diy blow lamp be up to the job ?
Also, can copper pushfit connections be used close to the boiler ? Our combi
reaches really high temps and has melted clip on plastic pipe covers at the
rads on the 1st floor above the boiler !. I want to add a rad in the new
extension next to the boiler and with pushfit it would be a pretty quick
Yes, but it isn't a problem. I've never used leaded solder for plumbing. The
lead free stuff works just fine.
You should use copper pipe for the 1st metre from the boiler, unless the
pipe manufacturer and boiler manufacturer agree that plastic may be used.
You should turn down your flow temperature if it is melting stuff. For the
specific question on copper push fit, check with the individual manufacturer
that the 'O' ring and any other internal components will be OK next to the
but you may find it harder work if your blowtorch isn't as macho as Chris'
Never use benders, but 100% agree on the torch.
It also lights fires and barbecues, and cigartters when SWMBO has hal
inched the last of the lighters and dropped it mindlessly in er andbag.
She uses it for creme brulee as well.
Oh yes. You can't light a barbecue any other way. Put down about 20
firelighters. Cover with charcoal, leaving ventilation holes near them.
Light with plumbing torch, starting at rear. After 10 minutes, use
firelighter Mark II (cheap burgers on the grill which spit hot fat into the
fire. Discard or feed to pets/children after 5 minutes). From laying the
charcoal to being ready to cook, about 15 minutes.
I saw an official brulee torch in John Lewis the other day. It was a
standard plumbing torch painted white with some name on the side something
like "HeatChef" or suchlike. Cost twice as much too, but I suppose would
pacify someone too scared to use a Taymar.
I have to agree, I have a Rothenburger Sure Fire. This is a nice tool
and take Propane or MAPP gas.
I reckon on it not owing me much now so if it dies (the ignition is
getting a bit unreliable) I'd be very happy to get a Sure Fire II which
has a knob allowing you to turn the heat down. Which would be useful for
soldering 15mm and smaller fittings. It was one of the best 50 quid I
ever spent on any tool.

My Bernzomatic has a handle, regulator knob and trigger ignition and only
cost about 30 quid. Doesn't take MAPP though, at least not to my knowledge.
I'm told it even works fine for 28mm, although I've only done 22mm and 15mm
myself. I don't turn it down for 15mm, though. I prefer just to do a joint
in a couple of seconds and limit the heating time.
