How much does it cost to power flush central heating system?

Tuesday 18th August 2020

Most people haven’t heard of a power flush. Put simply, it’s something that you can do for your boiler and central heating system. It is, effectively, a cleansing process, allowing you the opportunity to remove any items that may have accumulated in the system over the years, such as dirt, rust, or debris. If any of these substances are left in the heating system it could cause blockages and reduce the efficiency of your boiler, which may lead to it breaking down. Flushing a central heating system is something that should be done to guarantee the heating system is working at its best.

What Are the Signs You Need a Power Flush?

You may need a power flush if you spot any of the following signs:

  • Cold spots in radiators, which are often at the bottom. 
  • The pipes are continually blocked and noisy.
  • There are frequent breakdowns.
  • The boiler needs to be restarted.
  • There is discoloured water when the radiators are bled.
  • You have cold radiators but hot pipes.

Why Should You Have a Power Flush?

There are many reasons to have a power flush to benefit your heating system:

  • It improves the efficiency of your central heating system. 
  • It can save you money on household energy bills. 
  • It increases the reliability of the system.
  • It greatly extends the life of the central heating system.
  • The radiators can warm up quicker, adding extra comfort on cold mornings.
  • A better quality of heating and/or hot water.
  • Reduced noise from the boiler and heating system.

What Does a Power Flush Involve?

Using specialist equipment, a chemical is put through your radiators, pipes, and boiler at a high pressure. When the chemicals are pumped into the central heating system using the power flush machine, the cleaning chemicals will break down any sludge or debris inside the system. The materials collected end up in the machine and are removed from the system. It can take around 8 hours to perform an average job, but larger systems can take up to 2 days.

How Much Does It Cost for a Power Flush?

The cost can vary depending on the size of the system and the job needed. A typical three-bed home would cost around £460 (including VAT), and this includes the supply of the cleaning chemical. While this may seem costly, you have to think about the potential savings you can make in your heating bill. When you think about trying to power up the heating on a regular basis this can put a lot of extra strain on the system, but a power flush guarantees the system will run at its most efficient. But also, if there is a breakdown in the central heating system, this can be very costly. It would be far cheaper to have a power flush if you spot any signs of blockage.
