The Harsh Reality of a Cold Boiler


Winter is coming and so are the demands placed on upon your boiler system. To ensure that your boiler system is operating efficiently and safely Powerhouse recommends that a qualified boiler service technician open your boiler for a inspection. The fireside and the water side will require cleaning. When reassembling your boiler use new gaskets. Also clean and inspect your low water cutoff. Check all safety devices, including safety relief valves, flame safeguard checks and a leak test on all safety shut-off valves.

Note: If the use of fuel oil during the cold winter months has been an issue in the past, consider using a winter mix fuel oil. During cold weather #2 oil looses its viscosity and does not flow as freely as in the warmer months. The winter mix fuel has additional additives such as kerosine to increase the viscosity of the oil without loosing the btu content.

Below is a general checklist of items to inspect, clean, repair, or replace as needed. For more in depth information on why these precautions are so important, visit our Winter Boiler Safety Precautions article.

The Critical Importance of Water to Your Boiler

Unless your boiler receives water of proper quality, the boiler’s life will be needlessly shortened. A steam plant’s water supply may originate from rivers, ponds, under ground wells, etc. Untreated water contains dissolved minerals, gases and particulates.
