John–
I thought you might be interested in some input regarding the cost savings subsequent to the installation of the new system. Based on the last billing from BG&E for the 28 day period ending April 4, the household usage was 1661 kWh with an avg daily use of 59.3. The avg temp was 46 degrees. This included the several drain and fill for the hot water tank to get all of the sediment out. For essentially same period in April ’07 (but for 30 days vice 28 days) the usage was 2058 kWh with an avg daily use of 68.6 and an avg temp of 47 degrees. The big difference though is that the air coming out is now noticeably WARM where before it was not. That alone is worth the price of admission and it feels like we are getting something for our money. Thanx again.
