@ March 1, 2014 4:36 PM in Fire Sprinkler ProtectionI'm installing a sprinkler system that the design calls for 160' 0f 11/4" pipe over 10 hotel units. The problem is that the attic space is unconditioned. There will be 10 drops off of the main to the rooms below. Some of the units will be unoccupied in the winter months. The only thing I can come up with is to use Temp. sensitive heat tape then wrap in insulation. Does anyone have any other ideas.

@ January 19, 2014 12:11 PM in kick space heater with steamI would like to connect a kick space heater to a steam boiler using the tappings on the boiler below the water line. I will be using heat pex a circulator with a relay. Does the circulator need to have a brass body because essentially its an open loop system.
@ January 6, 2014 4:55 PM in Steam Pressure Short CycleA quick question about a steam boiler installation. New installation boiler runs fine with no problems until the customer sets the Thermostat back at night. In the morning the boiler will have long run cycle to come back from a setback. The pressuretrol will shut the boiler down when the pressure reaches 2 Lbs the pressure will drop in 2 minutes to restart the boiler. The boiler only takes 2 minutes to reach the 2 Lbs and the cycle repeats itself. This continues until the Thermostat reaches its target temp. According to the customer it runs on 2 minute cycles only on long run cycles The pressuretrol is set all the way down to .5 and the differential is at 1 pound. Is this normal

@ December 7, 2013 8:25 AM in Copper Press FittingsI'm trying to weigh the pros and cons of moving from soldering to copper press fittings. I do mostly residential to small commercial projects. My concern is the price of the fittings compared to the labor to do the installation. On average the fittings are about 50% more and with some fittings like ball valves and special fittings can be up to 300% more. Even if you go with the press system it seems that your always going to be soldering some joints on the job i.e. zone valves, some air eliminators, water make up valves have solder joints. Does it make sense to invest in a product that will cost $1,500.00 to press a joint and the fitting may cost several dollars more. It may take me 1 minute to solder a joint and you could save in reality several dollars.
@ November 22, 2013 6:42 AM in moving steam pipingI have to move a steam pipe to an inside wall and the pipe is 1". Can I transition to 1" copper piping for this.
@ November 17, 2013 8:44 AM in steam pipes on interior wallsI have a customer that wants me to put a steam pipe in his kitchen which is exposed and re pipe to the exterior wall. Most steam piping I have seen are exposed outside of the wall is there a reason for this? Is it because the extreme heat of the pipe will condensate in a cold exterior wall or does piping in the conditioned space provide more heat to the room?
@ November 12, 2013 7:42 PM in small heat loadsI'm getting a lot of calls from landlords to separate apartments so each tenant pays there own heating bills from one existing boiler. Most of the apartments are only 1000 sq ft or less. Is there an inexpensive heat source I should be looking at or does anyone have any ideas on how to approach this? All are hot water heating.
@ November 10, 2013 7:00 PM in Gas companies in CT make big push into oil territoryMy local gas utility just sold out to a Canadian company. They are subcontracting the gas piping installations from the street to the homes to an outside company. Not only does the company do the gas mains in the street but they are also bidding on boiler installations to my customers! My gas supplier is now my competition!
@ September 20, 2013 6:56 AM in BTU MeterAny suggestions on a brand of run time meter that I should be looking at?
@ September 19, 2013 7:27 PM in BTU MeterI'm looking for a affordable BTU meter to separate 5 zones of hydronic heat in an apartment building that fed by one boiler.
@ August 31, 2013 7:48 AM in Service MaterialI have a large amount of circulators, controls and parts for servicing oil, gas and steam boilers. I would like to see them sold to the right person instead of sitting in my shop.
@ June 23, 2013 7:44 AM in How critical is this new 410a flareIn the install manual they also require you to use refrigerant lubricant on all of the flair fittings. I just installed 5 heads on one project and 4 on another, used refrigerant lubricant on all flairs and didn't have on leak.

@ April 30, 2013 6:46 AM in brass nippleI cant see how you can make a thread on a 1 1/4" nipple? I have dozens of dies but I cant clamp the nipple and thread the other end.
@ April 29, 2013 7:54 PM in brass nippleThanks for the replies. I did what Hot Rod said and drilled out a 1/2" male adaptor with a 5/8" bit and cut the threads off then soldered a nipple to the proper length. Always a help guys.
@ April 27, 2013 1:35 PM in brass nippleI'm threading a powder coated shower wand into a drop elbow in a shower. I have to use a rubber strap wrench so I done scratch the surface. If I use a 2" nipple I have a 1/4" gap on the surface and I tried to use a 1 1/2" nipple it buries the fitting to easy and I'm afraid of a leak in the wall that cant be seen.
@ April 26, 2013 5:54 PM in brass nippleI'm looking for a brass or stainless steel nipple that's 1/2" x 1 1/4" and 1/2" x 1 3/4" sizes for a particular project. I tried to make one without success. Does anyone know where I can find one.
