Is this like watching paint dry? I don't get it.

We finished plumbing the boiler today. We're holding at 12 PSI, no runs, no drips, no errors.

Now I need to get power to it and we'll be off to the races.

I guess my posts need more cowbell :!:

Does anyone know why they call it a Triadicator since it only reads two things, pressure and temperature? :)

Tridicator sounded better than Bidicator ?? :D

The "tri" term comes from the scales, (1) Temperature, (2) Pressure in psi, and (3) static Pipe Head (Altitude) in feet. You have to remember the gauge dates to when open pressure systems were common.

The gauge on the gas boiler at my parent's old house had the three needles. Could you explain this one:

3) static Pipe Head (Altitude) in feet.


I know what it means, but how does the gauge "know" this???

Approximately.... every ten feet up of water weighs 5 pounds per square inch. If a pipe full of water is 20 feet tall, you'll have about 10 PSI.

Your upper gauge is showing 11 pounds, so that's about 21 feet, just what the lower gauge is showing.

SO, if you have a four story house, you'll need at lest 20 PSI on the gauge or the water won't make the trip upstairs!

No leaks is a good thing. Check it also after the beast is up to temp.

Water at 60 deg. F weighs 0.433 lbs per foot of column height. So you can use a pressure gauge installed at the bottom of the column to determine the height. Since the density of water decreases with temperature at higher temperatures the water weighs less and the pressure also will be less (open systems only).

Are you sure it had three needles? Usually it two needles with one having a dual scale. Sometimes the pressure needle's pivot point is in the center, in that way you can have two separate scales. One for each needle end. Today's tri- gauge would have 6 scales, English plus metric scales, a 3 x 2. :-)

Absolutely sure. There are 2 scales, the top one having a black needle and scale for psi and a red needle and scale for altitude. The red needle rests below the black one, similar to the relationship between the hour and minute hands on a clock. The lower scale is temperature, black needle and scale.

I have looked closely at the gauge, I'm sort of fascinated by older gauges. A few years ago the glass had gotten quite cloudy and dirty, I took it apart and cleaned it.

We have sold the house, but I will be by there on Wednesday night, I can photograph the gauge if you like.
