Sludge or calcium build up in a heating system means there could be an underlining problem that’s allowing air to get into the central heating system, causing radiators and heat exchangers to corrode.
This leaves rust and debris in the bottom of radiators which corrodes down into oxide sludge. This then leads to blocked waterways in radiators, pipe work and heat exchangers.
Blockages slow down the transfer of heat which causes pipe, valve and heating control server damage. It will, in some cases, lead to boiler replacement.
Be warned: changing your boiler without power flushing your heating system first could lead to you needing another boiler in the near future! This also applies to the controls which may have also been replaced on the system – it will render your manufactures guarantee void.
Faster radiator “heating up” time
All radiators produce more heat
Boiler runs quieter
Overall central heating system runs quieter
No cold spots on radiators
Cheaper gas bill – making your money stretch further
Better hot water temperatures
Less risk of breakdown
More reliable and efficient central heating system, giving you a warmer house at less cost
What Happens If I Don’t Powerflush My Central Heating System?
Boilers can become so damaged that they’ll be deemed uneconomical to repair, requiring a replacement.
The efficiency of the system will be affected, costing you lots of money in fuel and system repair bills
Cause mechanical failure of pumps, motorised valves, heat exchangers and hydraulic systems in boilers
Pin holes will form in radiators and heat exchangers, requiring replacement or repair. Oxide sludge is like black muddy oil, so will damage anything it comes into contact with, such as carpets, worktops and flooring if it leaks or spills
