Boiler Turndown Ratio: What It Is and Why It Matters

Turndown ratios vary depending on the boiler. For example, if your boiler has a 3:1 turndown ratio, that means that at its lowest fire setting you will be operating at 33% of the boiler's full capacity. If you have a 10:1 turndown, that means that at its lowest setting, your boiler is operating at 10% of its full capacity.
