@ August 27, 2014 9:50 PM in Scorched Air vs HydrocoilDoesn't have to do with humidity but adding a boiler with all the associated material ie. expansion tank, water make up, air elimination, piping, wiring and glycol needed if the air handler is in the attic. You have another appliance to maintain and the cost of the installation doesn't make sense to me if you can just install a condensing furnace. You will also have a loss in efficiency through the heat exchanger.
@ August 4, 2014 6:05 PM in Brazing without nitrogen?!Ive been using a flair tool made for R-410 A refrigerant. I can see in the video how the thickness of the pipe increases.
@ August 3, 2014 11:00 AM in Brazing without nitrogen?!Does a double flair mean that you flair the same pipe twice
@ August 2, 2014 7:38 PM in Brazing without nitrogen?!All connections on Mini splits should be flared not brazed. the 1/4" line is so small the you could end up with a bead of brazing rod or solder in the line.
@ July 18, 2014 6:06 PM in Mod/con poll. Installers only.I would like to say #3 but when a customer calls with no heat and the boiler needs to be replaced and they have a very low budget you cant tell them to insulate and replace there windows before I install there new boiler, they'll be off to the next.
@ July 4, 2014 4:42 PM in Cleaning radiant tubingI like the cart but what solution should I be using.
@ July 4, 2014 11:50 AM in Cleaning radiant tubingI have a project that was installed with non oxygen tubing some time ago. The system has some sludge in it from the reaction with the boiler. I'm going to install a heat exchanger to isolate the boiler system from radiant system. Is there a product I can use to clean out the pex tubing. It seems to have sediment in it.
@ June 7, 2014 5:42 PM in Servicing Mini SplitsWhen servicing a mini split its some times required that you OHM the molex connectors. This is required to see if the EEV or thermistors are working properly. The problem I'm having is that I cant find a Meter that has small enough probes to fit into the molex connectors. I tried Radio Shack to find electronic test leads but I cant find one small enough. I had to twist stranded copper wire together and stick them in each hole and then use my meter to each copper lead for a reading. Does anyone know of a meter with leads small enough to fit into these connectors. There as small as a pin.
@ April 15, 2014 7:02 PM in Better Business BureauIve been getting calls from the Better Business Bureau. They want me to join claiming that they will get me work, Get my listing on the first page on Google, they claim that homeowners choose there contractors from them all the time. Whenever I here of them its usually someone that wants to complain about a company not choose a company. Does anyone have any input about them.
@ April 3, 2014 7:21 AM in what is the maximuin water flow through 1 inch copper at 50 psiI had an engineer design the system. It calls for a 1" line from the well coming into the hotel which is small. But it calls for 25 GPM from this 1" line. Is there a formula that can tell me how much gpm I can get with100 psi with 40' of pipe.
@ April 2, 2014 7:45 PM in what is the maximuin water flow through 1 inch copper at 50 psiI'm asking this question because the owner is installing 6 kitchenettes that the building DEPT. is now requiring a Fire sprinkler system for the hotel. I need to know the max amount of gpm is scenario will produce.
@ April 2, 2014 5:51 PM in what is the maximuin water flow through 1 inch copper at 50 psiI have an existing farmhouse feeding domestic water to an existing hotel. The hotel has ten rooms. The owner has told me that there were 2 other buildings on the property that the well in the house was feeding but were demolished at some point. The pipe size of the copper going to the hotel is 1" with approximately 40" of linear pipe. The pressure on the pressure tank is at 100 psi.
I believe they kept the pressure on the tank at 100 psi to feed all three building at one time. My question is, How many GPM will I get from a 1" copper pipe at 100PSI on 40' of pipe.
@ 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 3:01 PM in 1/2" pex homerun to iron radsTo make it easier you only need to run 3/8" pex to each radiator
@ 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.
