We have a 10-year old boiler fired up, and a chemical rep told us we should be using a series of chemicals to prevent corrosion and build-up of minerals. A rather expensive array of chemicals it seemed to me (about $600/year).
The guy who installed the boiler said this was just a chemical supply rip-off with vastly over priced, & not necessary chemicals. He said a shot of sodium metabisulfate would do all we need, with maybe an annual descaler.
Any thoughts on who is right?
