How To Optimize Your Condensing Boiler System For Maximum Energy Savings - kW Engineering

How to optimize your system. In summary, for optimal operation, condensing boiler systems need the return water temperatures well below the dew point of the boiler exhaust (for natural gas, this is around 140°F in the Bay Area and 125°F in Denver), ideally around 80°F or lower. Non-condensing boiler systems require the return water
