Use this calculator to estimate the annual cost savings and CO₂ reduction from returning more hot condensate to the boiler house instead of sending it to drain.
Returning condensate captures the sensible heat already paid for in your boiler fuel, cutting burner run time and fuel spend. Hotter feedwater also improves deaeration and reduces thermal shock.
Reducing make-up water lowers water, effluent, and chemical usage, while often decreasing blowdown requirements. Less blowdown means less heat lost up the drain.
A higher condensate return rate can also reduce CO₂ emissions and support sustainability targets—often with short paybacks.
