Hi folks, Our new Caddy add-on has now been working for three weeks, and I just wanted to share that it's working wonderfully. My parents (many years ago) had an old smoke dragon in their house, and although it kept us warm, I remember stoking the beast almost continually. Our home is roughly 1600sq ft, and we have used about 10-12 splits today. The temps here have been anywhere -10 to -16C. I am proud to say that I completed the installation myself, and even the inspector was impressed with the quality of work. My wife is even happier, as she's enjoying room temps of 21C most of the time. Looking forward to many new reports as the winter continues!
