Here is a pic of my furnace. If the expansion tank is supposed to go between the PRV's and the furnace it certainly isn't there.

This I dont understand, its the cold supply line. Part goes into the furnace and part goes into the ground. what is this?

Here is a pic of my temperature setter right? set to 180 degrees

Here is a pic showing the furnace in an 'idle' state. 14psi, altimeter reads 30, temp 90degrees

I just went back down stairs and with the furnace running the temp is about 120, and pressure is 30psi

Even if ther eis one buried in the attic somewhere it has problems. Adding an extrol tank to the system could never hurt.

Some systems used the pressure tank as the air scoop and put them at the top of the system so that any excess air would rise to the top of the system and into the pressure tank.


My idea of a perfect day: No where to go and all day to get there.
