Also, what kind of silver solder do you mean?
My heat sources at present are a Smith mini-torch (currently Oxy/Acetylene but will be Oxy/Propane when I can get to the welding supply house) and a Weller Butane torch. Sometime in the near future, I'll be adding a Propane/Air mini-torch from Micro-Mark. (This doesn't include the alcohol lamp & blow tube for really
All of them will get up to the required temperature required for most common silver solders (roughly 1400o) and, for very small items, can handle the much higher temperatures (around 2300o)required by jeweler's silver solder. Where the difference comes in is in how much is needed to heat the parts being soldered. My Weller can handle the really small pieces while the Propane/Air one should be able to manage the vast majority of the remainder which will leave the Smith for the "heavy lifting" (which, as you might tell, isn't all that heavy.)
So, building a boiler - ain't gonna hack it. Doing fitting makeups for the tubing et al required - an excellent choice. Anything else ... give it a shot.
Oh, and if you smoke, they make great windproof lighters.
