@ January 16, 2009 4:48 PM in Tired Of Explaing Design TempsWe use -20 for our design temp in western MA. We also figure 180 degree water. THis leads to slightly larger boilers and more radiation for a given space. It also means we can use outdoor resets and use lower water temps on the none design temp days. I have also noticed despite the debates concerning over sizing it usually does not mean that large of a boiler as there are not that many choices in size. If I lived closer to the shore or further south I would use a warmer design temp. The thing is we do not get calls for rooms only gettting to 58 when it is -20. With the use of outdoor resets we also do not get compllaints of short cycling. Every year we get at least a week to two weeks of close to -20.
@ January 12, 2009 8:47 PM in Drip line causing water hammer - how to resolveWhen was the pipe changed and was it replaced as it had been or modified? Size changed, pitch changed? Was the pipe reamed? Any pictures?
@ January 12, 2009 8:36 PM in steam boilerHave you checked you water level? The basics for vent function? From the pictures I believe the tank is simply a steam chamber meant to dry the steam before it goes up into the supply piping. There should be no moving parts in it. The photo of the sight glass appeared to show the water level was near the bottom of the glass. Has the system been serviced this year, flushed, skimmed, and cleaned?
@ January 12, 2009 8:28 PM in How to replace Honeywell Thermostatic Mixing ValveIn the center of the cap there is a phillips screw. You will need to poke a hole in the label to reach it. When you remove the handle you can get to the stem retaining nut and remove the guts and replace with a new set.
@ January 12, 2009 8:22 PM in Where have all the professionals gone?Daniel I am 3 and a half hours away. I am guesing that is too far away. I used to spend my summers in Hoganburg in grade school.
@ January 12, 2009 7:29 PM in steam boiler replacement- big honking pipe systemZippy the HB smith G 8 is availible with a gas power burner. This brings it up to the mid 80's for efficency. The burnham mega steam is not yet rated fro a gas burner. Do to the fact you are boiling the water condensing tech will not help you out for gaining efficency.
@ January 12, 2009 7:23 PM in steam boiler water meterThe automatic feed has a built in water meter. I will look into the exact model we use. This is only for the feed water.
@ January 12, 2009 7:20 PM in Where have all the professionals gone?I was happy to try the offer it just seems many folks around here simply go with there fuel supplier or the plumber their neighbor uses and to be honest there is plenty to be done repairing installation gone wrong, It is nice to get in and do it right first for a change instead of sawzalling and repiping as the second one in the door. There seems to be a change as the economy slows down people are being more careful about going with the low bidder. It is hard at times explaining how a small shop and a fairly young looking person can do a better installation than the large fuel company with its fleet of trucks.

@ 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.
