what is involved in boiler maintenance?

Most new homes don’t come with boilers anymore, but there are many older homes that still have them. Like every other heating system, they need to be maintenanced and repaired from time to time. Boiler maintenance is different depending on whether the appliance is electric or runs on oil or gas. Here is how boilers are maintained:

For Oil and Gas Boilers: Check the Pipes
First, the power to the boiler is cut off from the circuit box.

Vent pipes of old boilers are made of metal, while pipes of newer boilers are made of PVC, or polyvinyl chloride. Whatever they are made of, the vent pipes need to be checked and cleared out if they are blocked. The technician removes rust, dirt and makes sure that all connections are tight and sound.

Oil the Motor and Circulator Pump
Newer boilers do not need oiling, but older ones do. The technician checks the oiler ports of older models and adds oil if needed.

Check the Thermostats
If the thermostat is wrong, you could be wasting money heating your home. The thermostat needs to be absolutely level on the wall.

After the thermostat has been checked and adjusted, the technician can then turn the power to the boiler back on, and turn up the thermostat. When the system has been heated up after some minutes, they’ll check the radiators, and bleed them if they have manual air vents. They’ll do this by opening them up a bit with a screwdriver and allowing water to come out of them into a bucket. The technician does this with all the radiators in the home.

The carbon monoxide detector is checked to make sure it’s working well. A CO detector needs to be checked once a month during the heating season. This is something you can do.

For Electric Boilers: Check the Connections
Electric boilers do not need vent pipes, but the technician still checks the connections to make sure they’re sound. They’ll look for burned or frayed wiring and replace it. Then, they’ll turn the power back on, start up the boiler and bleed the radiators as they would with a gas or oil boiler.

Boiler Maintenance For All Types of Boilers:
Check the Water Levels
This should be done about every two weeks. Ideally, the boiler shouldn’t lose water because water simply recycles through the ducts and the radiators and back to the boiler, but no system is ideal. Boilers that are forced to work without adequate water in them are basically bombs waiting to go off. If the water level is low, the problem most often lies in the plumbing. The technician will check the plumbing, and fix the leak.

Descale the Boiler
If too much limescale from hard water builds up inside the boiler, it can shorten its life. You should descale your boiler from time to time if you have hard water, or have the technician install a water softener. A water softener removes minerals such as calcium and magnesium from the water before it reaches your boiler.

Clean the Area
Dust and dirt around the boiler also make it less efficient. Make sure that the area around the boiler is kept clean.
