The Importance of Heating System Flush Maintenance

One thing that irks most homeowners is having to deal with a damaged HVAC system smack in the middle of winter. Often, the signs start showing earlier on that your heating system needs maintenance. Most homeowners disregard them or choose to attend to them when it is too late.
One of the ways of making sure that your HVAC system is operating at an optimal rate is by running a heating system flush regularly.

Why You Need a Heating System Flush

With regular use, sediments accumulate within your heating system and boiler. The result is the diminished performance of your heating system. One way to restore your heater’s optimal performance or maintain it is to conduct a heating system flush.
Sludge or residue occurs when air finds its way in the heating system, which results in the production of iron residue formation within the radiator as well as other parts of the unit. As the sludge level increases, it obstructs normal function of the heating unit.
Whether your system is new or not, it is important to perform a heating system flush. When installed, new boilers or radiators or their parts may result in the formation of sludge/residue build-up.
Including corrosion inhibitors would help in minimising on build up, but a heating system flush will equally do the job.

How is a Heating System Flush Performed?

A heating system flush is done by fastening a magnet filter and Flush Tool into the pipe work of the heating unit.
The only parts that are taken off are the radiator and heat pump. Throughout the complete flush, no other part of the system will be detached.
The Flush Tool forces water to the filters, radiators, pipe work, and coils, and this gathers all iron sludge residue that is then flushed out. A corrosion remover is added, and often it is phosphoric acid. The boiler is switched on, and infrared thermometers are used to find cold locations.
Corrosion is then removed from all regions where cold readings have been identified. pH and TDS Meters are used to examine the water dispelled from the system until it is completely clean.
Once the flushing is complete, the heating system is restored to its working condition.

The Benefits of performing a Heating System Flush

As discerned, the primary aim of performing a heating system flush would be to remove contaminants from your boiler and heating system.
Some of the other benefits of performing a heating system flush include:

  • Improvement in the life of the water pump, with sediments and other contaminants, flushed out from the water.
  • Contaminated water eliminated from the system and ultimately reducing chances of system corrosion.
  • Removal of cooler patches leads to improvement of the system’s heating ability.
  • A heating system flush also helps to reduce on gas gathering, which in turn leads to the reduction of internal corrosion.
  • The overall system performs optimally and in the long run, reduces on gas expenses.
  • Efficient warming of your home or office leading to lower energy expenditure.

As you can see, it is crucial to schedule a heating system flush to make sure that your unit is working as it should.
