5 Boiler Maintenance Tasks to Schedule Soon

Boilers are not like any other sort of residential heating appliance. The maintenance tasks involved are essential for preventing major accidents and injuries, as well as maintaining heat and comfort in your home. Heating maintenance for boilers should only be carried out by HVAC technicians. That said, here is what is generally involved in this particular appliance's regular maintenance schedule. 

1. Checking the Temperature Gauge

In each boiler there is a gauge that registers temperature. The temperature has to be maintained at a specific level to avoid blowing up the boiler. Your technician will check this gauge to make sure the temperature is correct and that there are no spikes during the maintenance visit. 

2. Checking the Vent Pipe

Boilers vent steam. The steam is exceedingly hot, so the steam is usually sent up a vent pipe that is routed through an old chimney. If your home is too new for an old chimney, the vent pipe might go through a hole in the wall to the exterior of your home. The technician checks this pipe to make sure nothing has blocked it or crawled into it and created a blockage (e.g., a bird, a mouse, a squirrel, etc.). The vent pipe and (if applicable) the chimney have to be kept clear to keep the boiler from overheating. 

3. Running a Carbon Monoxide Test

Boilers have a combustion engine that can leak carbon monoxide. Carbon monoxide, as you well know, can poison and kill your family in their sleep. The technician will run a complete carbon monoxide test on your boiler to make sure it has no leaks and that there is no carbon monoxide leaking out anywhere either. 

4. Checking for Holes or Cracks in the Ducts and the Main Body of the Boiler

Boilers work under intense pressure. It is not unusual for them to develop cracks in their ducts and in the main body of the boiler. Holes will develop over time near the water inlets, often caused by rust. The technician looks for these issues and then fills and seals the holes and cracks to restore pressure and keep the boiler running efficiently. 

5. Cleaning the System

The entire boiler system needs to be flushed and cleaned. Hard water tends to leave sediment inside the boiler, affecting the boiler's ability to function. Dirt and debris left on or in boiler components can also affect how the boiler functions and heats up.
