Will a VaporStat save me money?

The answer is maybe.

I am not aware of any calculations on fuel savings realized by use of a vaporstat. Nevertheless, assume for a minute, that you might save 2% of your annual fuel bill by using a vaporstat (around $40 on a $2000 annual heat bill). The cost of a vaporstat plus labor to install is $350 to $400. It would take 8-10 years to recoup the initial cost of installation before you began realizing savings payback. Does a vaporstat last that long?

My decision rule is to change to a vaporstat when my current pressuretrol dies and justity the expense by (1) realizing that I am an irrational "wallie" and (2) if I get hit by a bus tomorrow and my wife has to hire a "knucklehead" service person to maintain "my boiler" he will not be able to crank up the pressure beyond 16 ounces of psig.

PS. Vaporstat cutin (4 oz)and cut out (12 oz).

    Vaporstat

    My home steam boiler (Burnham I6) now has a subtractive Pressuretrol. Basically, the lowest I can run it is 1/2 on to 2 PSI off. If I change it out to a Vaporstat and run it lower:

    1) Will there be any real fuel savings?

    2) Will I still have to set the pressures up a little so the intermittent pilot has time to re-light before the pressure hits zero anyway?

    Any experience anyone can share with me would be helpful.
