Product Overview

Liquid Science Radiator Power Flush 1L HC1407 is an acid-based limescale and sludge deposit remover suitable for use in restoring old water circulation central heating systems in conjunction with Powerflushing systems. Suitable for use in hard and bore water areas.

Powerflush cleansing systems are only as good as the cleaning solution used to remove deposits of hard water sludge, rust and any other debris from your central heating system.

These impurities, if left, can seriously affect the efficiency of your heating system. Over time the water in your pipes, boiler and radiators deposit unwanted by-products like rust, scale and other debris which forms system sludge.

Sludge in your heating system can cause to blockages and corrosion which will lead to both inefficiency and/or breakdown. In extreme cases it can be so damaging that a complete boiler replacement is needed.

When used in conjunction with a Powerflush system, our Central Heating System Power Flush solution will remove even the most stubborn build-ups of sludge and debris to keep your central heating running smoothly, with a seriously reduced risk of breakdown or loss of efficiency.

The product is powerful enough to improve the flow of cold and distressed systems where hot water isn’t available.

Directions for use:

To clean a central heating system in accordance with BS7593:2019, Central Heating System Power Flush should be circulated with all valves open for a minimum period of one hour before flushing. For badly contaminated systems a longer circulation period may be necessary. Warming the system will aid the process. No neutralisation procedure is required. After cleaning, the system should be drained and thoroughly flushed through all drain points with clean water. Refill and treat with Central Heating System Corrosion Inhibitor.

Dose Rate: One litre of Central Heating System Power Flush is sufficient to treat a typical domestic central heating system with up to ten radiators. For larger systems an additional bottle will be required. Overdosing does not present a problem.

Dosing Instructions:-

Open vented systems: Dose through the fill and expansion system – sufficient water must be drained from the system to ensure that all of the product enters the circulating part of the system;
Sealed Systems: If the system is empty add to any convenient point before filling; if full, dose through any convenient access point. Suitable with use with all types of power flushing equipment.


Directions for use:

Always test the solution on an inconspicuous area to ensure desired results.
Apply the solution to the area to be cleaned with a spray, mop or cloth, leaving in contact for 5 to 10 minutes.
Wipe clean with a cloth, sponge or mop
