Deja vu all over
again. Thats the unit. Its Russian because it sits morose for long periods of time followed by short term spectacular destruction.
I bought the internal part of the unit from
Tempcast. Its been single digit cold here for several days so its not quite keeping the house warm enough. I'm going to put a heated (maybe pellet stove)sunroom in the front of the house, eventually, which should remedy short term severe cold snaps. Normally, it doesn't even require a second fire every day.
