Annual operation and maintenance costs for a 4-ton gas boiler
Thread Content
Hello, experts. For a 4-ton gas boiler of the model WNS4-1.25-Q, what are the approximate annual operation and maintenance costs? Labor is not included. 1. Industrial salt 2. Internal inspection 3. External inspection 4. Laboratory reagents 5. Ion exchange resin 6. Exhaust gas detection 7. Others. . .
The internal inspection is carried out every two years, while the external inspection is done once a year. For the specific costs, please call the local inspection agency directly; they will provide you with detailed information. There are also costs associated with certain inspections that may have been missed, including those related to safety valves and pressure gauges. Ion exchange resins are installed when a water softener is set up, and they generally need to be replaced after a few years. Industrial salt needs to be calculated based on your water replenishment level, and the testing reagents depend on the number of tests you conduct – how many times a day
Thermometers need to be checked every six months, while pressure gauges must be inspected once a year in accordance with safety regulations. This estimated cost is also quite high. . .
Thermometers are not mandatory; in some places the regulations are not strict, so it’s not necessary to have them checked. Calibration of pressure gauges is now free of charge
That makes things much easier. . . . . . . . . . . . Any amount saved is helpful; calculated in this way, the annual costs for various inspections and maintenance on a 4-ton boiler must be around 6–7K, right?
