@ January 12, 2009 7:04 PM in Where have all the professionals gone?Dan my last name is Garrity.
@ January 12, 2009 7:02 PM in Expansion tank placementI am installing a trio boiler for a customer and I was discussing the piping diagram that came with the boiler with my Da. This sparked the comment "Do you want people to think you are drinking!" from my Da. THe diagram calls for the expansion tank to be on the return along with the boiler feed. I noticed the Vitodent boilers call for this placement also. What is the way most of you are doing it? Da wants the feed and expansion tank on the header as we do with the other boilers we install.
@ January 12, 2009 6:32 PM in Where have all the professionals gone?Dan I actually took you up on your offer and received a total of one call. and that call was a no go. I feel in the smaller areas people do not go to internet for there heating and plumbing service. I think in the larger areas people are more frequently online looking for services.
@ December 23, 2008 5:07 PM in Radiant floor heating helpRadiant temps are usually under 100 degrees F on the supply side. This is why there is a mixing valve as boilers usually like warmer water going through them. This is also why set backs can be trouble some as water temps delta t's do not allow high speed recovery. It is like driving with a block under your gas pedal. You can get up to highway speed and you will save fuel but you may not get up to highway speed as fast as you would like.
@ December 23, 2008 4:56 PM in To cover or not to cover; that is the radiator question...Well they only lean on them once if they are smart twice if not so smart, three times means they need help and a padded room. The other issue with covers I have seen is dirt. when the cover is clean the homeowner is happy but they do not see all the dust and dirt and what have you that has gathered over the years. Some radiators, actually called convectors were made for and used covers. This is different from the after market covers sold through the hardware stores and such places. I vote tag sale them or recycle them.
@ December 23, 2008 4:39 PM in Boiler piped for reverse flow?Ok so if this is true, WHy do we not pipe and oumo this way? I would gues it is a throw back to gravity and steam systems where out had to be the top? Also would the pump then have to over come the natural convection of the hot so would then need to be larger since it is in practice swimming up stream in the thermal currents?
@ December 23, 2008 10:06 AM in staging steam boilersIf prperly controled and set it will save energy. THe factor is size of system and cost of 2 boilers and related piping verse one large boiler, possibly even one with two stage firing. Whats the fuel and whats the total EDR? The two boilers fire to fill the system then one fires to maintain pressure.
@ December 23, 2008 12:21 AM in Boiler piped for reverse flow?This was sometimes used to supply zones from a steam boiler. The rads could not be more than 7 feet above the boiler water line.I would say it would reduce cavitation on large pumps as the mass of the water is above the inlet side of the pump.
@ December 20, 2008 10:00 AM in steam and radiantShawn use a heat exchanger or tank or a tankless heater on the boiler if it is availible and NOT being utilized for domestic hot water. The water temp can be high enough if things mess up to damage the Pex tubing. The heat exchange device of your choice will seem cheap compared to ripping out a system and highering someone else to do it correctly.
@ December 19, 2008 12:11 AM in Friday FunnyOK now which Home depot was this? Just so I make sure to "avoid" it.
@ December 19, 2008 12:08 AM in Radiant Cooling on a Dubai Beachnot sure of the wonders of compressors actually but I figured they could do wonders with that kind of funding. They do have solar collectors that can produce steam for powering turbines. Why could a heat pump not be designed to boost the heat to make steam? Seriously why not? Maybe the future of steam systems, geothermal steam boilers. May save that one for Iceland though.
@ December 18, 2008 11:57 PM in Condensing vs. TraditionalWhich contractor did a heat load for the boiler sizing? Which one seems most familiar with their product? The concerns are real but also the condensing boiler can do well with a system like yours IF it is installed and maintained correctly. Was your system formally steam or was it Gravity Hot Water?
@ December 18, 2008 11:51 PM in drop header pics?Brain fart with what I was trying to say SteamHead. I said drop header when I meant dropping into the main supply line. If you look down at the gravity 2 boiler diagram where they have the steam going up to the main supplly they do not require the trap. I like Smith boilers as a whole I just am not a fan of their I&O manuals. Thing is the last blue Smith I put in I was the helper and that was a long time ago. On larger steams weil mclain has been our choice more due to wholesaler availibilty than brand preference. Even the best boiler is not worth dealing with if the supply house it comes from is not up to par.
@ December 18, 2008 9:48 PM in burnham mpcAre you sure Burnham will allow the gas burner with out effecting warranty? I asked for the megasteam and I was told no by our burnham rep for a gas burner.
@ December 18, 2008 9:42 PM in Replace Peerless or install Prestige and fork over another $4k?Bob you may be on to something there. I always had fun as a kid scaring my sisters by blowing through the flex supply tubes.
@ December 18, 2008 9:39 PM in drop header pics?Tim I was looking at the Smith piping diagrams and they want the F&T trap if you drop into the main off the header. If you can go with out a drop into the main off the header and maintain the pitch you do not need one.
@ December 18, 2008 9:22 PM in Low Water CutoffYes this piping does cause wet steam. I would suggest getting a pro in for an idea on what it will take to get it running the way it should. CHeck out the posts under Sleepless in Boston.
@ December 18, 2008 9:09 PM in drop header pics?Drops are awesome for what they are made for. tight dimensions to the water line and header. also they dry out the steam for the high fired small boilers. They also add joints for expansion between the sections, this is what I like about them. But they are not required if you have proper piping near boiler and into the mains. If you follow the diagram with the boiler and you meet their heights you should be fine.
@ December 18, 2008 9:03 PM in \"Stupidity\" wins againThanks for taking the time to share.
@ December 18, 2008 9:01 PM in Replace Peerless or install Prestige and fork over another $4k?The best of equipment is not worth a dime with a poor installation. and vice versa. Being sorry may not be what you need in a contractor, Being competant and familiar with the equipment is. Remember most high end boilers need special piping and wiring for the most out of your boiler.
@ December 18, 2008 4:17 PM in Radiant Cooling on a Dubai BeachI would say the hotel will need lots of hot water so perhaps the could go geothermal for domestic water production and even use the heat to produce steam for electrical generation? Solar cells could also be used to shade areas for the electrical needs. It would be ironic how few green house gasses they could end up producing if they thought things through all the way.
@ December 18, 2008 4:07 PM in Day The Earth Stood StillWait they are letting engineers on here? I got to talk to Dan about this right away.
