6 Reasons Why You Should Power Flush Radiators?
- Quicker heating radiators
- Heating costs will be lower
- Rooms heated more evenly
- Longer lasting system
- Avoid expensive power-flush further down the line
- Safer boiler, because replacing a boiler isn’t a small task
How To Fix Cold Bottom or Cold Spots on Radiator
This problem is usually caused by a build-up of sludge at the bottom of the radiator. This prevents the hot water from reaching every column of the radiator.
What Is sludge?
Sludge is tiny fragments of metal and dirt. As time goes by your radiator and system will rust and sludge will start to build-up.
Sludge can seriously clog things up preventing the water from flowing around freely. This will make your boiler work harder and your system weaker
What is a Power Flush?
A power flush is a chemical solution that cleanses your central heating system and removes any elements inside of pipes.
How Long Does a Power Flush Take?
It usually takes around half a day to power flush a system thoroughly. You can expect a power flush in a three-bedroom house with a vented system to take around 4-6 hours to perform.
Who Should Carry Out a Power Flush?
It is always recommended to have a power flush performed by a qualified professional. ABC is trained to handle the specialist chemicals and equipment that a power flush requires.
When to Flush a Radiator?
The Sludge Test
- Noisy boiler
- Radiators take longer to heat up
- Cold spots on the radiator
- Radiators require bleeding more often
- When you bleed the radiators, the colour of the fluid is:
- Clear: You probably just needed to bleed them.
- Slightly brown: Sludge is starting to build up. An ideal time to flush.
- Very dark brown: You must flush. And quickly.
Is Power Flushing a new radiator required?
Flushing new radiators shouldn’t really have to happen. Finding cold spots on a new radiator may mean that the boiler system already has some nasty sludge in it. This could have contaminated your new radiator.
Central Heating Filters
Magnetic filters are great to ensure the health of your system over an extended period. They attach to your boiler and as the water runs through, the fragments of metal are grabbed by the magnet preventing build-up elsewhere. They are easy to install and can reduce your annual heating costs by up to 6%
