Plumbing / what speed for circulating pumps is best?

« on: January 19, 2012, 01:06:02 PM »

i have a closed system in my garage. i have a pump from my OWF into my garage then aheat exchanger in my garage with a closed loop system on the other side of it feeding my garage floor system.  what settings should i have my pump on my OWF set at? what speed should my garage floor be set on? both are grundfos 3speed pumps. i also have a seperate loop heading into my house from the OWF on a 3rd pump.  i'm just trying to fine tune my pumps for best heat exchange to my garage floor.

Heatmor / chimney pipe suggestions

« on: January 02, 2012, 02:43:45 PM »

hey there, bought a heatmore 200 this spring and and have been running since first week of november in west-central pa, without a chimney as per suggestion of my dealer.  i've decided a 6' chimney and cap will benefit me and not sure what kind of chimney to get.  isn't the stainless triple wall insulated a bit overkill( and expensive)? being it's outside shouldn't need the insulation.  the only other thing i've seen is 10 gauge 8" pipe, but only one guy selling it. it kinda seems like he's got the market cornered.    guess what i'm asking is whats cheapest and what does everyone else use? and a website for such product. thanks yinz.
