How hot should water in boiler be?
The average setting for a gas-powered hot water boiler is 180°F. This provides the appropriate level needed for most cold weather temperatures. If you can raise the temperature manually, do not set it any higher than 210°F (which is often the limit), and try to remain down at 190°F if you need the extra heat.
What is the steam temperature for a boiler?
Because a steam boiler makes heat by producing steam – by boiling water, at sea level, the temperature at the boiler will be boiling or 212 °F or close to that figure.
Why is my Weil McLain boiler not working?
1. No Heat At All A burned-out thermocouple is the top cause of a Weil McLain boiler not responding to the thermostat’s call for heat. 2. Little or No Heat Insufficient water pressure will prevent the boiler from creating enough hot water to adequately heat your home.
Where to find thermostat on Weil McLain boiler?

How does the GCM protect the boiler from condensation?
When the water returning to the boiler is below 130 °F, the GCM regulates the bypass circulator and system circulator flow rates to raise the return water temperature up to 130 °F before it enters the boiler sections. By balancing these flow rates, the GCM can protect against condensation even if return water is as low as 60 °F.
