Boiler Piping Flow, Pipe Efficiency, and Proper Sizing Boiler Piping Flow Pipe Sizing. Typically these issues occur when the pipe is over-sizedunder-sized or the pump selection is incorrect and provides the incorrect velocity for the system. A good example of this is as follows. Two brand new boilers were installed in the basement.

Sep 25, 2017 The gas line size will depend on BTU rating of the water heater, the other gas appliances, and where they are installed on each branch from the meter and regulator. There are two methods for determining the required pipe size the longest length method or the branch length method. See Gas Pipe System Sizing for more information.

Im trying to figure out if a customers gas line is big enough to add a water heater with a great BTU input. All the connected appliances, including the dryer and cook top, add up to 270,000 btus. They have 34 black pipe from the meter, which then branches off to the various appliances. From the meter to the furnace room is about 25.
Gas Usage and Pipe Length. The amount of gas used by your gas range is measured in cubic feet per hour cfh. To convert the BTU input rate into cfh, simply divide the BTUs by 1,000. For example, if your gas stove uses 65,000 BTUs, the cfh usage would be 65 cfh. You can use this information alongside a gas piping table to determine the diameter ...
Aug 11, 2018 400,000 BTUhr is a little less than 400 cubic feet per hour. A 1 line should not be longer than about 25 feet for this capacity. And that doesnt include the total of all other gas devices used in your home, assuming the line size you are referring to is the pipe from the street to your meter. A 1.25 would let you get to around 100 feet of pipe.
Feb 13, 2009 It is not a pressure issue, since the pressure remains the same no matter what the pipe size is. It is a volume thing. A 12 pipe carries about half the volume of 34 pipe. Just like you would not plumb an entire house with 12 pipe, you really shouldnt run 12 gas pipe to a lot of appliances that may have a high btu demand.

Im planning on installing a tankless water heater that maxes at 160K Btu. I only have a 12 line from the meter to the furnace75K in the same room. The city told me that there is 2lb gas from the meter to the house. The sizing charts that I found say that 12 2psi black pipe will handle the btu draw for both the furnace and the water heater.
Mar 01, 2012 The pipe size is the black iron pipe size. The larger ones look to be almost 3 OD. I ordered the 1 thick fiberglass stuff locally today and will buy some sort of tape for the elbows and other fittings. I guess I am looking at a boiler in the 70-100k range.

Nov 18, 2010 The specification for these is going to be different, with different figures. Obviously, the greater the nominal size of natural gas pipes, the greater the gas flow through the pipes. With an 8-inch pipe youll have 141,832 BTUs in a 10-foot pipe. For a 150-foot pipe that will be reduced to 36,621.
Feb 18, 2018 Received 12 Votes on 9 Posts. From the charts I have been able to find, the 12 gas line should supply an adequate flow of gas to your home , if the pressure at the regulator is 2 psig. The chart shows that 12 sch 40 pipe will supply approximately 460,000 BTU through 100 feet of 12 pipe at 2 PSIG. The in house piping should also be adequate.

The BTU refers to the heat output the furnace creates. The average furnace has a BTU rating of 80,000 to 100,000 BTUs. Youll want to look at a units BTU as well as its efficiency. For example A furnace with 100,000 BTU and an efficiency of 90 delivers 90,000 BTUs of heat to a home the remaining 10 is what is lost through the flue.
