Hi, I have an SSU-45 indirect water heater that I want to descale / flush. It is 10 years old, and as far as I know it has never been cleaned. Would white vinegar be an effective solution for descaling? Would I get better results with one of the commercially available products, i.e. Flow Aide?
Thanks, J

The vinegar is cheaper, but probably should run longer than a chemical. Mine I usually run over night with vinegar.
This is what HTP recommends.
You can choose to do what you want, but you cannot choose the consequences.
