It's been some time since I thanked you for building such an energy-efficient home about 15 years ago.
As you know, temperatures have dropped here overnight, reaching more than ten degrees below zero.
This morning, starting at 6:45 am, I started tracking the outdoor temperatures each hour and the performance of the 10-zone radiant heating system you installed in this award-winning house.
The number of zones calling for heat at 6:45, 7:45, 8:45, and 9:45 am were 3, 4, 1, and 0, respectively, while the outside temperatures were -7.6, -7.7, -4.5 and 0 degrees F, respectively. The temperature in the insulated but unheated garage remains at 45 degrees.
In my recollection, I had never seen as many as four zones calling for heat in the winter. You will recall that you also installed the ductwork for the AC, should we need it.
The house stays cool in the summer, and there has been no need to install the cooling units.
Thanks again for your mission of building energy-efficient homes. Goodness, as everyone knows, the price of energy has gone through the roof with no end in sight.
It's hard for me to believe why more builders do not follow your lead for this type of construction.
Have a great weekend.
