Construction Update
Good news!
Propane was delivered day before yesterday. I calculated the average quantity used per day since the tank was last filled in October and compared it to the average for the same period last year. The unfinished addition (aka solar room or attached greenhouse) has reduced our propane consumption by a little over 50%.
The approximate inside dimensions of the room are 11 by 30 feet. The entire south wall (30 feet) is double pane glass. At present 14 barrels containing 770 gallons of water are being used for heat storage.
Just before Christmas we did last minute checks on insulation and air leaks and then hung drywall. The ceiling has not been installed but insulation and vapor barrier are in place. We have 7,600 pounds of flagstone on site which will be used for the floor. The opening for a door between the addition and the house is planned but not in place. Much work remains but some of the benefits are being realized.
Before our Christmas trip I configured the weather station to collect data every two hours. The following graph shows outside air temperature and inside air temperature for the period December 19 through January 1.
Inside and outside temperatures December 19 through January 1. (Larger version)
The minimum temperatures were 58.7 inside and 5.9 degrees outside. The maximum temperatures were 96.6 and 53.4. The heat was provided by the sun. There were no additional heat sources.
I’m pleased with the results thus far!

Right! Very Good!
Hurry up and finish then you can come do my house.
Amazing! However, which color is which? And why isn't there a lag time between the outside and the inside temperature increase and decline? Is this WITH the water barrels filled?
