metal brushes

On thing you want to do to keep your home running efficiently with heat and hot water, is to preform basic maintenance on your central heating boiler. This includes regular cleaning in down times as well as maintaining the pipe lines to ensure energy is not getting lost in your lines.

Your central heating boiler can run efficiently through proper cleaning and maintenance, and the following will explain the best way to go about cleaning your boilers fire chamber and the main water lines. Build up in the fire chamber can cause heat dispersion issues as sediment can build in your water lines causing corrosion and bad circulation.

Step 1 - Boiler Shutdown

Shut off your central heating boiler to avoid injury during maintenance. These steps are going to take you through cleaning the boiler, and purging your water lines of any buildup. Once all main lines have been shut off open the boiler and look into the actual fire chamber.

Step 2 - Boiler Cleaning

Open your central heating boiler door and look at the fire chamber inside, this is where the heat is created and then travels through the walls of the boilers heat exchange to water lines running throughout the home. Clean out the majority of the silt and ash with your ash shovel and place it in an ash can for disposal. Be cautious of the silt getting into the air while cleaning out the chamber. Use your micro filter vacuum to clean out any left over particles that come from scrubbing the insides clean with the metal brushes. Cleaning this inside chamber will allow for a more efficient heat transfer through to your system.

Step 3 - Replace Filters

On your central heating boiler, there will be a number of fuel filters to clean out impurities and the like from the source lines before they get into the burner area. Your oil filter is located on the side of your oil pump and has to be removed from the casing using the bolts that hold it into place. Remove these and replace the filter during regular boiler maintenance, be sure to dispose of the old filter properly using all state and local laws.

Step 4 - Bleed your Lines

The build up that can takes place in the water pipes can affect the boiler output. Flushing your water system should also be part of your boiler efficiency maintenance as if the lines get impurities and sediment build up it can cause heat loss and unbalanced heat exchange.

Your central heating boiler will have water line inputs for fresh water feed as well as release valves and purge valves. The purge valves are what you will want to use to clear your lines by forcing pressure through the lines. Use standard methods to top off your water levels and retain the appropriate water pressure. You can get certain additives that can be added to your cistern that your system pulls from to prevent sediment building in the lines going forward.
