I go another oil delivery yesterday. I've been tracking my oil use and the degree days for a few years. But let me back up a bit.
A few years ago, I was doing some research on a new oil fired boiler for both heating and hot water. One of the suggestions was from Chris Young, the Stormin Mormon at hangs out here. He suggested I look into the System 2000 by Energy Kinetics. I did and I bought it.
The literature on their web site says you can save up to 40% over the old style boiler like I had. Doubtful, I figured if I save even 20% it would be a good deal. I had the system installed and started doing the comparisons. My real savings was 39.2% the first season. My oil supplier verified it and so did Energy Kinetics.
This morning I put the last two deliveries into my spreadsheet, I got the degree days from
The system is paid for itself in a few years with oil cost savings. At the time of purchase, I was able to get a state energy rebate, Federal tax credit and state financing at 0% interest.
