In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
energy usage this winter .. (it is over now right??)
as some of you might recall .. this winter, I did things a bit differently .. I ran my heat-pumps during non-peak electric hours and my boiler during peak. as well, I had eTRVs installed on all rads and only heated the radiators that were below settemp. All temps were set at 70dF both years.
I started record keeping this season around 10/22/2010 .. as of today, below is my oil consumption usage.
OIL: 10/22/2011 - 3/26/2012
USED: 469.557 gals @ ~$3.50/gal
HDD: 3134.7 (degreedays.net 65F daily, KLGA)
Electric: 10/21/2011 - 2/25/2012 (they read MARCH today I will update upon receipt of bill)
Cost: $829.17 ($0.16/kWhr)
COST OF eTRVs: $1200
TOTAL COST 2011/12: $3675
Previous year 11/1/2010-4/1/2011
USED: 1000 gals @ ~$3.35/gal
HDD: 3972 (degreedays.net 65F daily, KLGA)
Electric: 10/21/2010 - 3/25/2011
Cost: $754.96 ($0.21/kWhr)
TOTAL COST 2010/11: $4104
SAVINGS by running eTRVS + Heat Pumps: $429
And the wife-comfort-meter this year was no different than last.
So my eTRVs paid for themselves ($1200) and I saved about $200 (assuming March electric is about $200). The cost of oil went up but my consumption dropped by ~40% (gal/hdd). Electric cost me only about $100 more than I would have spent had I not run the pumps. Yes the winter was much more mild (3972 HDD (2010/11) vs. 3135 HDD (2011/12)) .. but I still feel that I did pretty well with the way I ran things. Next year, there won't be the $1200 investment in eTRVs.
I hope this is interesting to someone. I'd love to get other people to share their stories of consumption this year.
