Weil McLain Troubleshooting Guide

the domestic water can approach the temperature of the boiler water. REMEMBER: All water heaters (direct and indirect) will stack. Reducing stacking within the tank (Non-Warranty) - Reduce the boiler operating temperature to 160ºF - 170ºF. This will limit the maximum domestic outlet water temperature during high stacking water usage.

The water that is being heated flows on the inside of these tubes. The SRU series is designed so that waste flue gas temperatures even below the water dewpoint (58C – 136) can be reached. The SRU waste heat recovery unit has a large gas-side heat transfer surface of aluminum fin tubes, with the fins and the tubes formed as one piece.

Boiler Efficiency - an overview | ScienceDirect Topics

For every 20°C decrease in the gas outlet temperature of the air heater, the boiler efficiency rises about 1%, with inherent fuel consumption reductions. It has been observed worldwide that leakage rates of more than 30% are not uncommon while rates of 15%–20% are typical.

What temperature should a condensing boiler be set at

The outlet temperature is the water temperature after it leaves the boiler. From what you describe, the last person that programmed the boiler set the space heating temperature not to exceed 160F. If you consistently get the error message, have a professional find out what the problem is. It could be a pump not working or a bad sensor.
