Some of you may be interested in this.

I just got an oil delivery and wanted to calculate the real difference in
efficiency of my old versus new boiler. I use the mentioned web site to get
the information I needed from a nearby weather station. This is the way the
oil companies figure the automatic delivery for you.

My savings over the past 10 months has been 40%. A real savings of 248
gallons. The new boiler is paying for itself in oil cost.

You should inform what boiler it is and post a link since few know of
that brand.

The boiler is a System 2000 www.energykinetics.com Very pleased with it.
The hot water system is a big saver over the summer booting the overall
savings to the 40% mark. Last year in about the same time I bought 668
gallons versus 372 for the same period, but using degree days compensates
for seasonal variations and slight time differences. .

So it seems you are the first person id believe that this system might
actualy be better, and honestly advertised, since I dont think you
work for the co or heard about it before I mentioned it a year-years
ago. Does this have a Energy Star rating? Isnt what you have rated
only at mid 80s in efficency? I thought you needed something like 92%
minimum for Energy star certification and rebates. I wonder if it
would be better than a condensing for a gas boiler use.

******************************************************************

I'm both cynical and skeptical so when I read clams of "up to" I perk up and
take notice. Energy Kinetics claims and "up to " of 40% so I figured I'd
come in less than that. Happily, I was wrong and so far have achieved that.
Once I hit a fill hear I'll be able to tell better. My thinking is, the
summer savings was even higher and brought up the 32% of the heating season
way up. No that we're heating more, it may drop down to the mid to high
30's. Still very good.

Yes, it is Energy Star rated. While the AFUE is 87.5% the real rating is
higher than most designs. You can see the comparisons here

My old system was the one in the fist column of the graph at 55%.
