Why is my boiler not cooling

HVAC

The answer to 'why is my boiler not cooling' is that the boiler is likely not functioning properly. Common causes include a malfunctioning thermostat, low water pressure, mineral buildup, or a problem with the circulator pump.

If your boiler is not cooling effectively, you may notice that the radiators or baseboards are not getting as hot as they should, or that the water temperature is not reaching the desired level. This can be caused by issues with the boiler's internal components or the overall heating system.
