Heating Help

slightly askew

@ June 2, 2005 10:15 PM in Want to Use Muchkin Boiler?

actually just posting here so the thread will show up back in the main Wall menu so I can bookmark it. I'm wanting to hang onto the Tagaki comments as I have just been looking at using Tagakis as a heat source for a couple small radiant systems. any other way that anyone knows to bookmark an older thread without reviving it like this?

thanks, guys

I wasn't tuned into the staple mode til now but checked with one of my wholesalers this morning and they can get me a stapler for $209 (which sounded pretty good compared to a wirsbo model from another supplier for $381). they weren't sure but thought it might be a roth. so a stapling I will go. got a couple pretty big bags of zip ties now should anyone need them ... :-) Roy

anchoring pex to foam

@ June 1, 2005 10:24 PM in anchoring pex to foam

wondering about people's prefered method of tieing down pex for radiant slab installations. I have mostly zip tied to wire mesh or rebar. I am questioning that method as my desire is to keep the tubing low in the slab (usually 4" thick) whereas if the mesh or rebar is intended to be structural, which it usually is, it wants to be up in the middle, which puts the tubing too high in the slab, at least for my preferences. has anyone used the plastic clips that screw into the sub-slab foam insulation? not sure who makes them but I know that in my area, at least, they are sold at Menards (a regional big box), along with a drill operated installing tool. other favored approaches?

external heat exchangers

@ November 5, 2004 8:35 PM in indoor wood boiler?

are preferable in my estimation, for safety reasons. I've done lots of internal heat exchangers in wood stoves but always with convective delivery to storage (not dependant on electricity but storage can't be below the heat source). Downside to external is that much less heat is available and so you might find that hot rod's copper lines (or some other conducting pickup HX) works better - or maybe you just use lots of fintube.
