The minimum exhaust temperature recommended for boilers typically ranges from 250°F to 300°F (121°C to 149°C) to prevent condensation of flue gases, which can lead to corrosion and damage to the boiler and chimney. Maintaining this temperature helps ensure efficient operation and extends the lifespan of the equipment. However, the specific minimum temperature can vary based on the type of boiler and its design, so it's essential to consult the manufacturer's guidelines for exact recommendations.
