Title: Oil furnace problem
Post by: Roger2561 on March 04, 2015, 11:57:28 AM
Hi all, I'm hoping one of you pro's can help me a bit.  Why would the temperature of the water in my oil burner exceed 200 degrees when the 8151A triple aquastat high limit on the "HI" is set to 190 for summer use?  In the fall, winter and spring when I'm not using oil to heat my DHW or my house I turn the settings down on the "HI" to 150 and on the "LO" to 140.  I only use the oil burner in the summer for my DHW; it has a tankless coil in it.  The reason I ask is on Monday evening I decided to exercise my oil burner (I do this once a month) by turning the "HI" to 190 and the "LO" to 160 on the triple aquastat on the oil burner, but I noticed that the water temp went beyond 200 degrees on the temp guage on the oil burner.  When it reach 205 or so, I turned it off out of fear of something bad happening.  All help will be greatly appreciated.  Roger

Roger, it would be either the sensor in the well is not getting a good reading, the aqua-stat is sticking or the temp guage on the oil burner is reading wrong, is everything working correctly when it is turned down?

Yes, it appears that it is operating correctly.  The only time I hear something from the triple aquastat side of things is when a zone calls for heat; I hear the contactor make connection and the circ come to life.  I don't know if this is important but when I set the "HI" limit to 190 the oil burner did not come on immediately.  It only came on after I set the "LO" to 160 and only then did the oil burner come on, but it kept running past the "HI" of 190.  Roger

The 160 is for the protection of you domestic water temp, it simply maintains a low set point in order to heat the hot water, you either have a faulty aqua stat, bad reading or bad temp gauge, any of which should require a tech to service it

Slimjim - Thanks for the help.  I'll contact my oil furnace (he installed the thing 22 years ago) guy and have him fix it.

Jeez, some of us have been out of high school just a tad bit longer than that.

And, unfortunately, some of us are much older than that.   :(   Roger

Meh, actual calendar age is irrelevant.

The fall of 2013 we put up three more grain bins on the farm, did the cement ourselves and the actual installation of the bins (we own our own bin jacks).

Had the hired mans boy and one of his friends working for us on that project, they are less than half my age, I could work their little d*cks in the dirt, work a couple more hours after they left, then go and throw darts that night on the league, end up at the VFW and drink beer with the old farts till 1AM then be up hours before the "kids" showed up and work their little d*cks into the dirt again.

Genetics play a big part on your actual physical age compared to your calendar age. My great grandfather was still farming in his 90's, driving the baling tractor, milking cows, etc. When he fell down and broke his hip at 96 he didn't last another 18 months when he couldn't work anymore. My paternal grandma is reaching her late 90's as did all her siblings, grandfather didn't last that long but all his siblings did. My maternal grandmother made 94, grandpa didn't but his siblings did. On my Dads side when you goto a funeral for somebody that was only in their late 70's or early 80's you'll hear more than once "they were young yet". I'm serious, no joke on that one.

Unfortunately nobody on the wife's side seems to be very long lived, high blood pressure, cancer, strokes, glaucoma, cataracts, kidney issues, etc.

As cliche as it sounds, you're really only as old as you let yourself feel. A lot of the friends that the wife and I hang with are in the late 20's or early 30's.

Someday I'll have to grow up and act my age but I plan on kicking and screaming all the way. 8)
