Today Ken (S&K Electric) and I replaced 5 heating elements in Zone 2A and 2 in Zone 1B.
There were several elements burned out in Zone 3A so we relocated the remaining elements in order to bring these up sequentially as they were designed to do. These elements are a different style and we did not have replacements. I will order more after the first of the year. 

With the exception of 1A, which has some issues that will be addressed after the break, we are now able to turn on heat in all of the zones.
