Are those hour meters

@ October 1, 2007 6:40 PM in I think we have a winner!!!

on the ZV's? By far the most confusing zone valve you will ever wire :) You have one of the best tekmar reps around right there in Salt Lake. Mike or Dave at Lundquist Sales. You need to meet the team at Hydronic Supply LLC at 2195 s West Temple. Hands down the most knowledgable supplier in the valley. Dave Hill, Bill McDonald, or Frank. They know copper boilers very well :) I believe they are tekmar dealers also. hot rod

Make mine radiant floor heat!

@ October 1, 2007 6:04 PM in Heating Garage with gas fired infra red radiant

talk to mechanics and other folks that work on concrete slabs for a living. I think you will find hands down the radiant floors are their first choice. Another feature of hydronic radiant floors is the multi fuel options. From mild to wild. Wood, geo, electric, biomass, solar or combinations of. A couple hydronic unit heaters for shoulder season loads. Nothing against over head radiant, it certainly has a place. depends on where you want the warmth most. if it on your feet and under cars and equipment, etc floor radiant is my choice. And concrete is such a good medium for shop floors... and hydronic radiant. The Delta repair hanger in Salt Lake has radiant floor heat. it can open wide enough to swallow a 747. They did some testing when that was built as to warm up time after that big cold bird was pulled in. Talk to those mechanics about perfect heat :) hot rod

good point Kevin

I need to research the adhesive on this product. I have found some thermal conductive adhesives with continous duty at 600F. I'll bet something is available out there. Or mold the tube right in with the layers?? hot rod

a cast iron boiler connected to radiant?

@ October 1, 2007 12:39 PM in White stuff over front of boiler

flue gas condensation is known to produce the white powder you may be seeing. Any boiler return temperature protection? hot rod

Mighty fine

@ September 30, 2007 10:12 PM in My new Knight install

better then some pros! One thing I found helps is to elevate the boiler about 20- 30". Much easier to adjust, clean and service. Not a deal breaker by any means. Nice piping work. hot rod

I've learned a ton

@ September 30, 2007 10:04 PM in \"Never work for an engineer or an attorney.\"

from engineers I have worked for over my 30 years in the trade. A few know it alls along the way, but easy to work around with the right attitude. And if and when I need a legal opinion, I won't call any of the plumbers I know :) Life is like a box of chocolates.... hot rod

many of the current mod cons

@ September 30, 2007 9:59 PM in Stage and Rotate

have this feature built into the control. it even allows exercise programs, data logging, error logging and much more. The method for step firing mod cons differs from a traditional boiler sequence control. The control watches the output temperature and will actually ramp down the "first on" to keep it in the most efficient condensing mode and ramp in number two at low fire. tekmar probably explains it better than that ;) hot rod

Too bad a savy manufacturer didn't

@ September 30, 2007 9:51 PM in Should the trade 'pigeonhole' its young talent?

provide them with some shirts and hats before they boarded the bus :) I agree with not judging a book by it's cover. But also with the dress for success motto. I would think the school and instructor would want to present his class in the best possible light to prospective employeers. It really has little to do with their desire or technical talents. Nothing but employment opportunity at an industry trade show like that ;) On your own times anything goes. Sounds like they were on school time, maybe their parents nickel, or a tax payer funded class? In a way the instructor set them up for some second looks. I'd wonder if he would have an anything goes dress code for an industry event next time? I'm curious how you would like to see you child dressed to attend a event like that, John. hot rod

Take a coil of pex

@ September 30, 2007 9:32 PM in rusty fill issue

and feed right from the main at the point of entry to the fill valve :) Bypass all the bad pipe. Why is the valve being asked to auto fill? Most times a one time use is all they ever get to provide. If the pipes in the building are really that bad, faucets, ball cocks, fill solonoids, etc are not going to like it. Thime for a pex pipe re-plumb possibly? A band aid is just a temporary fix, treat the problem not the symptom. hot rod

If they fix it and...

@ September 30, 2007 9:25 PM in Pro Press fittings

it turns out after an O-ring analysis that it was and installation issue, then what? Plenty of variables can cause an O-ring failure. I think in all fairness a third party should be allowed to forensic engineer one of them. Here is a company that provides some data and services. I wonder too that cleaning one of the fuzzy joints would answer some questions. Isn't it possible they seeped a wee bit until they got "wet". Maybe the seal is now complete. A good question for the folks above. Reading their data, EPDM gets along fine with glycol. I have had a slug of name brand ball valves fail to hold a 60 psi air test lately. Once the water was introduced they sealed just fine. Even with another air test. Harold, what exactly do you want to happen? Every joint replaced with solder fittings? Threaded fittingg? Just the seepers replaced? To me this doesn't sound like a problem that should take a lot to resolve. hot rod

I look at the amount of BTUs to be moved

@ September 30, 2007 9:04 AM in Zone valves or pumps

generally my zones require 1-4 gpm. A whole house rarely over 100K. So 1 circ easily does that work with zone valves as the zone control mechanism. Most small wet rotors have their sweet spot around that 6-8 gpm figure, so they operate at peak efficiency at design load. Plus the power consumption of one 80 W circ as opposed to 4, 6,6 or as many as a dozen circs on some jobs we see! I may change my opinion as we see more and more ECM circs hitting the market. Been playing with some Grundfos Alphas and watching them do a fine job at 7- 17 W consumption! hot rod

I suppose it depends

@ September 29, 2007 9:00 AM in Treating Condensate from ModCon boilers? How important?

on what the drain is connected to. In a new home with all PVC drain lines I doubt any harm would be done. I'm on a septic tank and the warm condensate runs through the tank into a leach feld of limestrone. I'm not too concerned. I'd expect the same with a system connected to a city wide sewer system, probably plenty of dilution waters. i don't recall seeing FA furnaces with condensate neautrilizers. They have been aronnd for 20 years. Still, it is a simple and inexpensive device to build. I use a tube of 4" PVC with a closet flange on the bottom (plugged), for a base and a Fernco cap on top for ease of removal. Drill and tap a 3/4" PVC ell at top and bottom. hot rod

PHP and Radiant Engineering have some

@ September 28, 2007 8:50 PM in Low loss headers

Watts Radiant will soon. Sinus has some wild looking stuff. They have a dealer in WI, Radiant Ted that hangs here. And one in Canada. hot rod

I like the Rhomar products also

@ September 28, 2007 8:40 PM in fernox superfloc

they make a multi metal boiler cleaner that is second to none. It is being speced in many aluminum and stainless boilers. hot rod

I've seen it in Canada

@ September 28, 2007 3:46 PM in fernox superfloc

as I recall there were some EPA issues with importing it into the US. Did you try a websearch? Theis site should give you reps or dealers. hot rod

Sounds like they

@ September 28, 2007 8:39 AM in Piping question (SE)

may not understand, or believe the concept of the hydro-separator? Adding another P/S loop would complicate the calculations on actual water temperatures getting to the zones, as you have two blend points to deal with. As I see it. hot rod

Sounds like a great time

@ September 28, 2007 8:35 AM in BSA Wizard Camporee - solar

if it gets boring, turn the buffalo lose in camp :) I remember my 50 mile hike with the scouts on the Appalachian Trail. We got rained out big time and a troop from Boiling Springs PA sent their bus and bailed us out and set up a dry camp for us in a city park. Nice folks back in the Keystone state. hot rod

I have another REMS tool

@ September 27, 2007 10:11 PM in Tube Bender for 1/2\" M Copper Suggestions.. Please.

that will swedge the ends of hard copper without needing to anneal it. It just heats and streches much like a T-Drill does. With the bender and the HURRICAN swedger, fittings and solder joints are minimized. pressure drop is also minimized and insulation likes the sweeps better than 90 ells :) The CURVO is a a great tool for solar panel installation. A few measurements and bend away. Throw in a Press fitting and all you need are the tees and threaded adapters. I have made multiple bends on a 20 foot stick of copper. Not unlike the electricians do on EMT condiut. You can buy bending software programs for exact multiple layouts. I did the trial and error method. hot rod

Same thickness

@ September 27, 2007 10:03 PM in A \"super\" heat transfer plate (hr)

as the heavy extruded aluminum. I actually used a U-fin and some 1/2 od copper to form the shape. It sticks very well to the smooth pex tube. Once stuck it de-lams trying to remove it. The first sample has stick-um on one side and a clear film on the opposite side to keep it mess free. I doubt the tube or the plate would make any noise. It if fairly flexible, like thick gasket material, and a low thermal expansion factor. This company can do just about anything you might imagine. Vary the graphite "cooking" process for different effects, either up and down or lateral heat spread, vary the thicknes, backings, cover sheet and material. They could even laminate a stiff plastic if need be. I think the potential is great. I think it would make an excellent solar absorber plate also. Better thermal performance, no corrossion, great color, less cost, etc, etc. So much to do so little time :) hot rod

I doubt

@ September 27, 2007 9:46 PM in BSA Wizard Camporee - solar

I could get it there that quick. rare to get anywhere over-nite from Springfield, MO according to both UPS and FedEx.. We've tried before. How about your solar oven? That is always a big hit for solar newbies. We attended the Missouri Renewable fair last weekend. A fellow had a row of solar cookers baking breads and carrot cakes. He also does all day chicken and roasts with his. Neat technology, the sun and a box with mirror around it! hot rod

Bending is very common in Europe

@ September 27, 2007 9:38 PM in Tube Bender for 1/2\" M Copper Suggestions.. Please.

that's why most of the small power benders come from there. I'm not sure how their copper gauges compare to our K,L,M designation? Some day I will mic the wall thickness at that outer bend radius just for grins. No doubt it will be thinner after the bend. How thin is too thin? I'd rather not risk a pin hole or stress crack. For my customers I'll stick with L. I know the Copper Development Association suggests velocity of no more thean 5 fps in hot water lines and 8 fps in cold. Typically 4 fps is the desigm max. for hydronic. hot rod
