During the 2021 season, there were multiple observed instances of the boiler operating at a sub-optimal temperature. To prevent condensation, the boiler should operate at about 120 degrees or higher. This is achieved by mixing inlet water (ideally at 80 degrees or warmer) with water recirculated from the boiler outlet. This circulation pump is shown in the <b>Boiler Loop</b> section on page 2 of the [[Process Flow Diagram]]. | During the 2021 season, there were multiple observed instances of the boiler operating at a sub-optimal temperature.

The occurrence of low temperature was likely due to air trapped in the pump; a condition that is possible after air is introduced into the system when the [[strainer basket is cleaned | The occurrence of low temperature was likely due to air trapped in the pump; a condition that is possible after air is introduced into the system when the [[Cleaning the Strainer Basket|strainer basket is cleaned]] or the [[Backwashing|filters are backwashed]]. The controller cannot prevent this condition, but it can detect it and alert the operator to minimize the impact of condensation. | ||
