What is Powerflushing?
A Power flush is a cleansing process for your boiler which removes any dirt, sludge, rust and debris that may have accumulated within your system over time. If these substances are left in your heating system, they could cause blockages or corrosion and ultimately reduce the efficiency of your boiler – they could even eventually lead to a breakdown.
Why Powerflush?
If sludge and debris is not removed from heating systems, it can accumulate in radiators, pipework and heat exchangers, causing severe blockages. This diminishes the transfer of heat and can result in pipe, radiator valve and heating control servo valve damage. In some cases, this will eventually lead to the premature failure of the boiler.
Signs your system needs a Powerflush
There are several signs that could help you decide whether your system needs a Power flush. These include:
- Cold spots on your radiators, particularly at the bottom
- The radiators require constant bleeding
- Noisy radiators and boiler
- Radiator leaks
- Frequent breakdowns
- Boiler constantly needs to be restarted
- Central heating takes a long time to heat up
- Some radiators struggle to heat up more than others
- Discoloured water when radiators are bled
- Cold radiators but hot pipes
What are the benefits of getting a Powerflush?
There are plenty of benefits of getting a Power flush. These include:
- Enhanced energy-efficiency
- Improved system reliability
- Potentially lower energy bills
- Reduced likeliness of boiler breakdown
- Could increase system lifespan
- Radiators can warm up quicker
- Better quality of heating and hot water
- Reduced noise from boiler and radiators
What happens during a Powerflush and how long could it take?
Using a specialised machine, a chemical is circulated through your radiators, pipes and boiler at a high pressure. This flushes out any potentially inhibiting deposits and thus allows water to flow freely throughout your system. The length of time needed for a Power flush typically depends on your system’s size and condition. Usually, a Power flush can take around 8 hours to perform.
