I have a DHW coil in my Koker; and, it works great! But running the Koker 24/7/365 is unrealistic to generate DHW; so, I'm upgrading to an AHS S-130 Coal Gun boiler. I plan on running the Coal Gun year 'round heating the house (with a heat exchanger in my FHA plenum, using my existing furnace as an air handler), heating my DHW, and heating my in-ground pool.
The boiler arrives tomorrow, Friday 3/25. I plan on installing everything (except the new coal bin...) Saturday 4/2. I hope to have detailed digital pictures of the whole thing... My wife is the official photogragher!!
