  • Effects of Ultra-High Turndown in Hydronic Boilers By Sean

    Boiler turndown is important for fuel savings—especially during low-load conditions and also reduces the wear of burner components. Example: if a 2,000,000 Btu boiler has a 5 to 1 turndown it is capable of modulating from 2,000,000 Btu to 400,000 Btu.Get Price
