It is the type of movement that occurs where all motion follows the longitudinal axis of the pipe.
What is axial movement?
This unit heater which inducts air into it is usually called this.
What is a vertical unit heater?
What is ASHRAE?
If your baseboard radiation covers three walls of a square room, you will need some form of this?
What is an expansion joint?
Baseboard heating units are rated in these units specifically.
What is BTU's per linear foot?
If your expansion loop needs to clear adjacent piping, you should consider using this.
What is an offset expansion loop?
82 degrees Celcius or 180 degrees Farenheit, is this type of temperature for domestic hot water in an industrial plant.
What is the maximum temperature?
These are the only heat losses we calculate with volume, not area.
What are infiltration losses?
If you are installing your rough-in piping, you have hopefully already selected these.
What are heat transfer units.
These heaters give off radiant heat in addition to convection heat due to their high mass.
What is a cast-iron radiator?
This determines the number of corrugations required in a bellows-type expansion joint.
What is the amount of expansion to be absorbed?
Unless otherwise stated or calculated, this is the desireable temperature drop from boiler supply to return.
What is 20 degrees F?
These walls are our only ones we care about when calculating heat loss or where we would install our baseboard heating.
What are perimeter or exterior walls?
You should install these on their side to keep them from acting as a condensate pocket on a fin vector.
What is a strainer?
These units are available as surface/floor mounted, fully recessed, and partially recessed?
What are convectors?
If you pre-bend an expansion loop you would call the process this.
What is cold springing?
What is 500lbs?
If you don't have the wall space, just install this convenient fan coil unit.
What is a kickspace heater?
If you want to alter the air flow on a heat transfer unit, hopefully it has this.
What is an adjustable damper?
My outdoor design temperature subtracted from my indoor design temperature is how I can figure out this?
What is the Design Temperature Difference?
You should anchor and hydrotest a bellows-type expansion joint before doing this.
What is removing the shipping bars.
This valve has two outputs but only one input.
What is a three-way diverter valve?
You have to know this in order to properly size a boiler.
What is total net heat loss?
If this heating unit has one of these near the outlet, it probably runs on steam.
What is a vacuum breaker?
These are pretty much the same as wall fin baseboard, but bigger.
What is a fin vector?
