A turndown ratio refers to the width of the operational range of a boiler/burner, and is defined as the ratio of the maximum capacity to minimum capacity. Are you familiar with a boiler turndown ratio and why it matters? Lets review some key points. Benefits of a High Turndown Ratio
Dec 17, 2020 · Boiler turndown ratio defined . Boiler turndown is the ratio between a boilers maximum and minimum output. Depending on the burners design, it may have a turndown ratio between 5:1 and 10:1 or even higher. A 5:1 turndown means the boilers minimum operating load is 20% of the boilers full capacity ( capacity divided by 5).
Jun 29, 2009 · The Laars Rheos+ boiler has a 5:1 turndown ratio. This means that the boiler can modulate down to 20% of full-fire before it will turn off ( ÷ 5 = 20%). This turndown ratio provides a great advantage in the single heat exchanger boiler such as the Laars Neotherm, as well as in the dual heat exchanger (copper/stainless steel) such as the Laars Rheos+ .

What does boiler turndown ratio mean? | U.S. Boiler Company
A general rule of thumb, 3.5 litres of condensate is produced for every 30kw of input providing the boiler is operating in full condensing mode. A boiler having 30kW of input operates for 1200 hours annually will produce approximately 4200 litres of condensate.
Sep 03, 2013 · In larger buildings, hospitals, and central plants for large school campuses, the building engineer and maintenance staff may have their workspaces in the boiler room.
