I am no engineer or even half educated on this. Can some one give me some information on an additinonal tank setup? I have a CB 6048 and it is heating two seperate structures. I want to add a heat sink storage tank to help even the speratic ups and downs of the CB as it cycles through burns. I am thinking of adding a 500 to 1000 gallon tank right next to the CB. I have a recycled 500 gal tank for nothing. I thought of putting it half in the ground and insulating the thing until it looks like the Michelan Man. I think that the tank is lower than the mass in the CB and will gravity feed down. I am thinking of a small pump to push back up to the CB tank. I have also considered a tank in each building, the problem is space. I think I can fit 250 in the house garage and 300 in the other out building(provided I can get it through the door)?? Thoughts?? Other considerations: I am in the interior of Alaska, temps are commonly 30 and 40 below zero hear. Coldest Dec-Feb. If I put a tank in the garage this is not much problem since the door is large. The other building the door is 32 inches wide? Any thoughts would be great thanks.
