Previous owners of our house had installed a solar hot water system. When we got the house it wasn't working. I had long since removed the panels from the roof as their weight was damaging it. However, the hot water holding tank that was part of the system, was installed on the side yard, near the actual hot water heater. For some STUPID reason they had built a "closet" around it. Apparently they figured this tank would never break or need to be replaced because there is absolutely no EASY way to remove the tank without destroying the closet or the tank.
SO for the 14 years we have lived here I have been trying to remove the tank with out destroying the closet. A couple of years ago I bought a pair of pneumatic shears to cut away the outer covering of the tank, but had nothing to cut the tank up with. The tank cannot be rotated as there are pipes coming out the top of it in to the closet containing the hot water heater. The pipes cannot be removed because I cannot reach the solder joint without removing the roof. It cannot be tilted as the tank extends all the way up into the top of the closet. Nope, I will have to cut a large hole in it and then cut the tank up from the inside and remove it piece meal. Cutting torches and grinders are out of the question as I do not want to burn the house down.
I recently borrowed a reciprocating saw, and picked up some VERY expensive metal cutting blades from Lowe's. I managed to cut a decent sized hole in the tank. Hopefully over the next few weekends I will have this damn tank gone. NEVER give up! NEVER surrender!
