20 MEASURING HEATING ENERGY

21 Feedback - Dead of Winter Yesterday it was 5 degrees (F) for a high temperature outside. My house was 76 degrees air temperature inside at 5:00 pm, while the granite counters were at least 80 to 90 degrees. It was down right near tropical. What a performance the house is providing.

43 Feedback - Summer Heatwave Yesterday, despite the heat, my house was quite comfortable. This AM it was 76 degrees on the main floor, a bit warm, but very tolerable. I look forward to Thursday's cool off to ventilate the house overnight with open windows. It really ventilates well. Gary Konkol, owner June 7, 2011: High 95F with a 67F dew point

64 Hey Tim, This is funny. I had a problem with a frozen Humus package falling behind the lower freezer door preventing me from closing the door. I wasn't able to retrieve it nor determine how to remove the freezer door to retrieve the obstructing food item. I called the Liebherr customer service center and they provided me with guidance to remove the upper freezer door to reach the Humus and thus I was able to restore the doors to their closed position. Meanwhile, I was baking a pizza. I had a feeling that I was going to mess up my house's energy usage for today. It's nice to know that I have friends watching out for me.

65 Alert courtesy of Energy Circle Hi Gary, Your Oven used 26% more energy over the past 30 days than it did for the same period ending 298 days ago. If there are no obvious reasons for this change, it could indicate a problem is developing with this appliance. 'Oven' Circuit Summary Cost for last 30 days: $0 Carbon for last 30 days: 4 lbs Click here to log in to the emonitor Dashboard to view this circuit, see all of your electricity usage and costs, or update your alert settings.
