My experience with Warm Board

@ August 30, 2007 6:26 PM in Warm Board feed back

shows their output numbers to be very realistic. I've installed it in high load conditions, including large glazed timber frame and log (the hardest building to heat) homes. I also did some infared analysis of this product along side some transfer plate installations...It's that SOLID sheet of aluminum that is the key to the output. Router through the aluminum and break the conduction path and you really see the power of the aluminum. Regardless, the load numbers hold the key to how sucessfull ANY radiant, or other heating system performs. Lower the loads! Seems to me any building that cannot be heated with 27 btu or less per square foot has other "issues" Like too much loss :) Keep in mind high loads directly equates to high heating and cooling costs. hot rod To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"

efficient, and profitable... then why change anything?? It seems to me Rich, that the only side of the mechanical business that you haven't experienced is the OWNER. Listen to those that own and manage the $$ on a daily basis and you will better understand "what it takes" Just because others in you area so call abuse upfront pricing, doesn't mean you have to. The bottom line to all this is what my wife calls KFP Know Financial Position. Until your company has a handle on that position, changing pricing schemes may be an exercise in futility. Or mutiny as you call it :) But I'm pretty sure you know all this already. hot rod To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"

the REX show

@ August 30, 2007 5:02 PM in The Vaillant people were snooping around (hr)

talking to contractors about re-entering the U.S.market. Check out some of their cool stuff. A nice looking oil fired condensor. The use the new Laing ECM circs on many of their boilers. The Laing ECM circ may be here this fall, I'm told. They have a one piece mod con/ solar tank/ load shifting appliance. Nicely packaged in an appliance looking jacket. Geo Thermal heat pumps, pellet boilers, loas shift storage vessels were all shown in their catalog. Apparantly they are also close to releasing a solar powered air conditioner, powered by evac tubes. Joe from Oventrop claims solar ac is very close in their line also. I Googled solar powered AC to find info on units already being used in China and Japan. The grey beards among us may remember Vaillant had a line of cast iron boilers and some wall hung instantanous they sold here in the early 90's. Even though they pulled back they did maintain a warranty presence in N.J. They still do in fact. Thumbs up for that. hot rod To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"

It's not uncommon

@ August 28, 2007 1:12 PM in radiant heat

for the fluid to darken. Was the system cleaned and flushed before the glycol was added? Was the glycol mixed with DI water? Both of these steps would help assure the fluid stays healthy. Take a fluid sample and check the ph. This is one of the indicators that the fluid has, or is going bad. The label on thew container should tell you the ideal range for that fluid. Also check the freeze protection level. hot rod To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"

Here is the pressure drop chart for that tank

@ August 27, 2007 12:57 PM in Fixing problem w/ indirect water heater

If in fact it is a PowerCor.. As you can see 5 gpm is a whopping 53 ft of head. I'd say 4 gpm is more realistic although still 35 ft of head. The HX is 80 feet of .55 id tube, a fairly constipated HX. So based on this the heat exchange in that tank at a 4 gpm flow may not get 'er done to your liking :) hot rod To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"

possibly

@ August 27, 2007 8:41 AM in Is Siggy out there? Closely-spaced tees question.

I suppose it would depend on flow rates and the diameter of the trunk. I believe you need some "room" for the mixing to take place. Years ago I did a bulge fitting, sort of an early hydro separator device, that Siggy designed. It had the take-offs directly across from one another, but with a large 2" trunk. I have also done take-offs with just one tube space apart, and across from one another. hot rod To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"

Guess you shouldn't have cut into 'er

@ August 26, 2007 7:48 PM in Phase 3

Sometimes the tanks will get rust or sediment in them from the water source. It will stay at the bottom just fine until you open a very large draw. A full open condition can cause enough flow to the bottom to stir up the bottom crud. Same thing when you tip an old tank over or on it's side to drain them. Or something up stream of your tank has been "stired" ? A break in the city main supply pipe somewhere? A well tank going south? There is a procedure for filling that tank in tank type of indirect to prevent damaging the inner tank. What is the pressure on the boiler side of the tank? Got an installation manual handy? hot rod To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"

another thing about ball valves

@ August 26, 2007 7:38 PM in soldering ball valve worry

once they have had water in them, and you turn them to the off position to solder, or un-solder... If you get them too hot the water in the ball expands, or turns to steam and pops the seals out. Usually they are done after that pop. Never to shut off completely again. 1/2 and 1/2 is the safest position, unless you have a very low temperature solder. The thin walled brass ball valves don't take much heat to solder. Not like the cast brass versions, anyways. hot rod To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"

I have a few Ultras installed like that, Rich

@ August 26, 2007 7:30 PM in Fixing problem w/ indirect water heater

and a Munchkin. They work very well. Just as long as the DHW load isn't too large, and or long, to prevent space heating :) Most mod cons have a time out adjustment to prevent endless DHW priority calls. To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"

China will surpass the US to become # 1 greenhouse gases

@ August 26, 2007 5:16 PM in How Interested ?

this year. Is that a good or bad statistic for the U.S. of A? Certainly speaks louldly about our habits. Actually buy buying made in China products haven't we merely outsourced our pollution to them :) Dirty industry that was shut down here by EPA regs has sprung up in China and at a much dirtier level. Last year China produced more coal than the U.S., Russia and India combined. Burned in plants with few if any regulations. China does seem to have a plan for a "green evolution." And the power and money to make it happen. That would be a good thing for us, as we all live down wind.

Is it a new tank, and or problem?

@ August 26, 2007 4:53 PM in Phase 3

as you know the outer tank is steel on that style and brand. Could it have a leak? Pressure gauges and relief valves could tell. What about any steel fittings in the pipes? Or an iron bodied recirc pump. hot rod To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"

more output

@ August 26, 2007 4:49 PM in Fixing problem w/ indirect water heater

is possible with higher tank temperatures. Be sure to check the max temperature the tank manufacturer allows. Some are limited to 160, or less. Also be sure you use the correct, LISTED tempering valve of the correct capacity. Higher tank temperatures seem to cause more mineral and sediment issues, from my experience. Ideally you would determine your DHW needs and size the equipment, tank, circulator, and pipe size to that load and spec. If you feel you are close to the "goal" a bit higher temperature may help. Or a solar DHW pre-heat system :) hot rod To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"

The P-40 R10

is the style with the small diameter coil. The installation manual, available at the website, indicates a max 5 gpm through the coil. Guess what... hot rod To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"

the 40 gallon won't perform like the 80 gallon

@ August 26, 2007 1:38 PM in Fixing problem w/ indirect water heater

when you are looking at dump loads. Is the tank a new Bradford White PowerStor I believe is the name? If so it has a 1-1/2" coil and pressure drop should be nil. Sounds like the 3/4" pipeing would be the bottle neck? It would be nice to move 12 gpm or so through that coil from the boiler, as the boiler on priority could provide the hp. Not easily done with 3/4 copper, however. The older version Bradford White tanks had a 5/8" coil. Quite a bit higher pressure drop. I doubt it would handle a 150K input happily :) The Bradford White website should help you determine which version you have, all the data as well as performance is available there. Be sure to look at the btu input numbers, and boiler temperatures they use to rate performance. hot rod To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"

as the contractors that can't break the "wall of pumps" habits will be prime candiates for a more expensive Alpha Pro circ. Or another color circ altogether.

high head circs that consume

@ August 25, 2007 3:04 PM in Need Help...Cosmo

1/2 the power would be a good start. That is easily done with ECM circs. And also encourging the boiler manufacturers to port out the HXers. Climate Panel installers could also enjoy low wattage high head circs :) hot rod To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"

What a fun and funny lad he is :) A very sharp, "out of the box" thinker. Get in betweem him and Moses and the words per minute meter really pegs out :) It was great to see old friends and meet new ones. Nothing like putting a face to a "wallie" Plenty of interestig new products at the show. I like the Taco solar block with VS circ. The Cogen unit has my mind spinning. More and more solar vendors and products. Viega has one of the most impressive booths at the show, big, bright and a well staffed training facility. I met a few of the boys from Cedar Mountain Solar in NM. A very progressive solar/radiant contracting team. Russ Rose wined most of the attendees, as usual. Wheels is in his element as an RPA board member. A little power goes a long way. hot rod To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"

@ August 21, 2007 11:33 AM in Waste oil boiler- Buderus or Viessmann?

waste oil is an extremely messy fuel to work with and combust. Be sure you have easily serviced filters, and the oil is free from antifreeze and water. Quiz them on the types of oil the plan on burning. we have had some issues with trucking shops trying to burn waste synthetic crankcase oils. It just doesn't like to burn. I've heard a rumor that Canada is clamping down on waste oil burner installations?? Chose the boiler that is easiest to clean. That is a frequent service :) hot rod To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"
