What is a Hydronic Heating Power Flush, when do you Need One?

In this article, we’re going to explain what a power flush is when you know you need one, and what we do during a power flush service.

What is a Power Flush?

A Power flush is a cleaning process that removes deposits of sludge from a hydronic heating system and should be done every 5 years.

Over time this sludge builds up in your radiator panel, floor heating and your boiler. This mud-like substance slowly decreases the efficiency of your system, and in extreme cases can cause blockages, corrosion and damage to your boiler.  A Power flush removes it and should be performed every 5 – 6 years.

How do you know you need a Power Flush?

Signs that you need a power flush can include:

  • Your system is older than 5 years
  • Your system taking longer to heat your home than it used to
  • Increase in your running costs
  • Panels being cold in the middle and hot at the top
  • The system not heating at all if it becomes blocked

How we perform a power flush?

To conduct a power flush we disconnect the flow and return pipes from the boiler and connect them to our PowerFlush machine. This piece of equipment is made up of a powerful pump and a magnetic filter. We then close off all panels and circuits and flush each one individually so that the full force of the power flush goes through each panel or circuit.

The result of a power flush is that all sludge is now captured with our powerful magnetic filter and all water in your system is fresh. Your system will return to peak efficiency and you will again feel like you have a brand new hydronic heating system.
