@ April 14, 2014 7:14 AM in Help with Sizing a BoilerIf you do not have a boiler that can build pressure and you do not use TRV's heavily you will not like the way your system behaves if it is undersized. Steam will often find the one radiator you really want to heat up and not go there if the boiler is undersized. Note that the EDR rating for boilers has a 1.33 pick up already firgured into it. The only time I add a pick up factor is when reverse engineering to figure out the fire rating for a given system with either a gas orfice or oil nozzle. Too long of a run time during a heat cycle also wastes fuel. And you are cold while wasting fuel which is worse then an oversized boiler wasting fuel by short cycling, but keeping you warm.
@ April 11, 2014 7:51 PM in Tub strainer removalit is not quite the horsepower I have behind my hacksaw, but it is way faster then I can move the blade back and forth.
@ April 11, 2014 7:47 PM in Mass Oil Burner ExamI tried to post that from my phone today, but could not get it to post. I went to Georges class for those who have been in the trade for years and found it both helpfull in passing the test and in improving my understanding of the code in the real world applications.
@ April 11, 2014 7:04 PM in Can a Circulator Pump Past a Stopped Downstream Pump?yes it can. unless the head for that zone exceeds the pump curve.
@ April 11, 2014 6:44 PM in Radiator air vent preference?is the vent I use 80% of the time. They are the only adjustable that tested well in the Balancing Steam vent speed chart. If you can not get them near you then contact me and I will help you get them.
@ April 11, 2014 6:42 PM in Help with Sizing a Boileryour contractors edr the boiler to use would be the EG50. This is of course assuming you do not have any strange or excessive piping. A few risers in the wall would not be enough to bump you up to the EG55.
@ April 10, 2014 7:43 AM in Tub strainer removalit has a 3/4" stroke and low on power and it makes the cutting a bit less nerve wracking. it also use the same blades as the big saw-zall, so no double stocking of blades. It is now my go to for radiator spud removal.
@ April 10, 2014 7:26 AM in recommended NG Burner?If you go to there website it is in the product literature. I think it is the carlin 201 gas burner but Burnham can confirm that. if you do remove the sections to down size the boiler it may change the burner selection. While not a cheap proposal it would be the better long term answer as when the boiler is shortened it can also be properly piped.
@ April 10, 2014 6:50 AM in Questions regarding the main vent and auto water feeder that cuts off the boiler every 10 minutesI have not looked in the manual for your model but some can have this function bypassed. As for being tired of adding water, have you checked that under the floor pipe to see how big the leak is in it yet?
@ April 8, 2014 8:23 PM in Bad new gorton valves?can you post a photo of the radiator valve. Spitting vents are sometimes caused by the use of hot water radiator valves on steam radiators.
@ April 3, 2014 11:20 PM in Burnham gas conversionI only go as far east as Provincetown. If you are east of there I can not help you.
@ April 2, 2014 11:41 PM in To convert or notHe knows good people who can get this working well for you. Tim get one of your guys to put up an add, it helps keep the wall working for us all.
@ April 2, 2014 11:31 PM in Copper Joint that leaks in main pipe Solution pleaseand the solder needs to be silver bearing, 50/50 is too soft and the only stuff around now seems to be full of impurities. Copper should not be used for steam piping, but you know that. If you need to fix this I strongly suggest replacing it with iron and finding out the cause of the water hanging in the pipe or you will never be done with this.
@ April 2, 2014 7:27 AM in Value of converting oil/steam to modcon gas?If people could fix steam, did the math out, and understand steam they would never remove steam. Your last paragraph highlights my point clearly.
@ March 28, 2014 10:44 AM in Do you ever get sick of lookinginstall boilers I will never be out of work. Just looked at an 888 weil McLain with 2 four inch risers going into a six inch header that was about 6" above the jacket and welded straight into the header with the system supply right in the middle of the two risers.
@ March 28, 2014 9:34 AM in Adding cast iron baseboard to one-pipe steam systemyou need to pipe it two pipe if it is over 4' long. the return end needs either a trap or a water seal and a vent on the return end of the baseboard. As for putting the vent in the middle, it is hard to guess where the steam thinks the middle is as it is never the measured middle of the unit and it would have steam crashing together coming from each end.
@ March 28, 2014 9:26 AM in 10 PSI versus Maid-O'-Mistafter all this time you may expose leaks you never knew you had. Make sure if you clean it well it is on a day before a warm spell.
@ March 24, 2014 10:00 PM in Sizing steam boiler with indirect water heaterneed up sized for domestic. As long as it is sized for the EDR and there is not a crazy amunt of hot water needed.
@ March 21, 2014 8:06 PM in adding CI BB to a single pipe systemand baseboard works fine on one pipe. If it is over that I pipe it like the old two pipe air vent systems. Use a vent yet run the return back to a return with a air trap,
@ March 20, 2014 10:37 PM in Ornate Cast Iron Radiatorsthe tops are not connected across, they are steam only radiators. The valve by oventrop does not make these work on a forced water system.
