Today I arrived on site Steam Boiler Issue: Addressed a reported malfunction of the steam boiler. Heating System Zone: Confirmed the boiler supports the heating system zone. Fault Diagnosis: Identified a malfunctioning thermostat as the root cause. Resolution: Determined the thermostat needs to be replaced. Upon arriving at the property, the client explained to me that the heat is not turning on. I proceeded to verify the system. The tstat is not communicating with the boiler. I also found the spill switch when off. I showed it to the client and explained the system situation. I recommended the customer to consider replacing the Tstat. I also recommended that the client contact a chimney company to inspect the chimney draft. I presented the client with an estimate to replace the tstat. The client said that he will buy the tstat and install it by himself. The customer was left with heating temporarily. View visual findings from this job here - https://visionshare.xoi.io/?id=
