- Action: To Do List item A0130 – Clean scale buildup from heat exchanger core.
- Completed: 5 May 2016
- Cost: $0.0
The heat exchanger core tubes were essentially clogged up with the same white accumulation shown in picture below. The copper-nickel heat exchanger core easily slides out of the heat exchanger manifold.
The heat exchanger core was descaled of accumulations as best as possible using a mild acid bath. A stiff, small wire rod was used to internally scrape clean each of the core's water tubes. It was washed thoroughly, flushed with fresh water, and the exterior rubbed down with a cotton cloth. As on-hand common household cleaners were used, there were no items purchased for this effort - cost $0.0.
