@ July 31, 2003 9:14 PM in UNico hv systemhard start kit for this unit. it would consist of a larger capacitor and a start relay. basicly it will boost the start up voltage for the compressor, and then drop out when it is running. should help. Paul

@ July 30, 2003 8:01 PM in L-ventis rated for use as a vent connector. some of it is only rated for chimney use.( straight up as opposed to up or horizontal.) it would be a bummer to install it and then find out it was mis-applied. Paul

@ June 30, 2003 8:48 PM in Ground source Heat pumps and radiant/airhandlerslower water temperature. We have heated comercial jobs just fine with 125° water, without supplemental heat. Some heat pumps will put out 140° water with out any additional modification. Paul
@ June 9, 2003 7:57 PM in Homemade goodieclean that coil nearly as often if he was using the correct filter for his application. He needs to have someone make him a filter box that would hold a 4" 35 or 65% pleated filter. That fiber filter doesn't have the abillity to trap particulate in the micron range the equipment is obviously exposed to. Paul
@ June 5, 2003 8:12 PM in Ornamental gas log fireplaceornamental is just that. your lucky it is direct vent with glass doors or you would be ADDING hwbb to compensate for it. We hade one job where the fireplace didn't have glass doors and it was standing pilot, and the installer fixed the fireplace damper permanantly open so as to avoid liabilty, and you can guess how well that room heated when the fire was out.

@ May 23, 2003 7:39 PM in Air flow balancingis VERY important. most manufactures don't bog you down with efficiency curves for their equipment, but if they did you would see that relatively small imbalances in air flow (less than 10%) cause Large Loss of efficiency(20to30%). Thats why it's also important to keep the filters clean and the cells or cores or wheels washed and clean. as a filter loads up or the transfer medium gets dirty, efficiency goes way down. Paul
@ May 20, 2003 9:16 PM in Alex's theories brings up a questionis a Positive pressure over fire. They actually have a "blast gate " type damper on the breach connector. I have found occasion to install a barometric if the chimney has too much draft. some of the smaller boilers are positive over fire as well. a barametric is not required in every situation. Paul
@ May 14, 2003 9:42 PM in 2 floors of radiant w/ 1 manifold?the differance in thermal mass might cause a response time issue. Paul
@ May 14, 2003 9:36 PM in service call ????????and say that the old motor was mechanically switched, and the new one is electronicly switched, and you are getting feed back through it's circuit. I can't help you much because I'm not familiar with this particular valve motor, but it sounds to me that since it "hums and chatters" that you have both windings energized at the same time and it won't drive in either diriction
@ May 14, 2003 8:45 PM in service call ????????operate by cam and micro switch? because it sounds to me like you have a switch that has failed in the wrong position, or has gone out of sync. my two cents worth. I would add that if you have two xfrmr that either you have two motor windings, or someone twinned them together origanally to increase the va. Paul
@ May 13, 2003 8:45 PM in Need slab temp sensor for radiant?perimiter drainage, water traveling under the slab will increase your heat loss by about 40%. Paul
@ May 12, 2003 10:17 PM in propane tank locationTanks with a water capacity between 125-500 gal have to be 10' from bld, 10' from neareast buildable property line and 10' from an ignition source. Tanks with a water capacity less than 125 gal. only have to be 5' from a basement window and 10' from a source of combustion. they can go right up along side the house, and there is no property line requirement. The Buildable property line is the catch here, because if there are no buildable lines then technically the tank could go right on the line. I'd check that tanks DOT water capacity again, and make sure it is 300 gal water. I don't set tanks either but I do keep a copy of nfpa 58 because it has a lot of useful info regarding propane. you could go to nfpa.org and order a copy from them. hope this helps, Paul
@ May 9, 2003 7:22 PM in anyone had trouble starting a 12-R with 2\" die?you need to get a 2" nipple and "set" the die gauge to the pipe. you need to do this if you change out a die set in any head. you might also want to make sure that the die are installed in the correct numerical order. Make sure you are using a good grade of pipe as well. some of the lesser grades can have hard spots, and be slightly over-size which makes hand starting difficult. Paul
@ May 8, 2003 8:28 PM in dry cut sawmine is any louder than a regular chop saw. we usually hang a pair of ear muffs on the handle so hearing protection is with it. Paul
@ May 7, 2003 9:54 PM in dry cut sawpp 1191 DeWalt multi-cutter, pn 4yl17. there is also a ridgid shown, and porter cable makes one as well. You can not put a multi cutter blade on a regular chop saw, as abrasive wheels run at 5000 rpm and the carbide run at 1300 to 1500 rpm. That said, the tool is well worth the investment. Paul
@ May 1, 2003 8:25 PM in Looking for Heavy Guage Aluminum Pipe....Boilerproyou should check out Elmer's pipe at www.elmerspipe.com/ this company makes 22 and 24 ga. 316 stainless liners up to 12" dia. i have used this product to re-line chimneys and it is very durable, and not difficult to install.

@ April 28, 2003 8:34 PM in Thaw Pak tubeadditional response. your post contains some very useful info.This is a performance eng. project. I have their dwgs., and they supply the material through my local distributor. The pex is red ( o2 barrier) as opposed to the white, and I'm sure I will get the aluminum manifolds again on this project. the pex is marked thaw pak oxygen barrier tube 100 psi @180° astm f-876/877, so in theory I could use wirsbo propex to connect. Or maybe somthing with crimp rings. MY gripe here is that I haven't been able to get a repair fitting from the local rep that I'm comfortable with. The fittings I've been given in the past are simply a compression union with nuts and ferrules, and no inner brass sleeve to make the pex hold it's shape. These have a tendancy to leak over time and when they do start to leak tightening the nut only distorts the pex more.When I make a repair to pex I want it to last as long as the pex. If any one else has an opinion on suitable alternate means of connection i would love to hear it. Thanks much for the technical lesson Hot Rod. Paul.
@ April 26, 2003 3:45 PM in Thaw Pak tubewith an SDR 9 wall and a 1/2" CTS OD. I suspect it is being made by Watts Radiant and I was wondering if anyone had actually tried Watts' Crimp rings and fittings with it.
@ April 26, 2003 2:11 PM in Pnuematic staplerfor yours. I have a pneumatic fitting on mine that swivels 360° and left and right. The blue pneumatic tubing is a light weight, really tough tube that is a lot lighter to work with.
