Cold Spots on Central Heating Radiator

Cold spots on our Central Heating radiator may indicate sign of a clogged up Central heating system requiring flushing.


We do not always need to hire the services of a Central Heating Powerflushing company to do this; by simply connecting a hose from radiator and draining off a system couple of times can make a huge difference in your system .


Central heating cleaner, Inhibitor and protector chemical bought in 500ml or 1 l bottle , then introduce into system after the draining down and replenishment of water into system will help improve system smooth functioning henceforth.

Always remember to call a plumber as soon as your radiator starts to go cold 🥶.
