Repair holes in central heating radiator.

Oxygen in the water of central heating systems, if not scavenged and inhibited will eventually corrode any ferrous metals in a central heating system. Central heating radiators are prone to this corrosion, one or several holes may appear and a replacement radiator may be necessary. However, for small holes and small areas that appear to be weeping a good solution is the application of a two part epoxy putty. A repair to a leaking central heating radiator using this method can be a cheap and simple solution.

The epoxy putty used in this article was a multipurpose type

Brand Name: Milliput Buy on Amazon.co.uk

It is reasonably priced and very easy to use.

METHOD

If you are lucky then the leak in your central heating radiator will be easily located, finding the leak is beyond the scope of this article.
When you have located the leak then isolate the radiator by closing the valves at either end and collect the dripping water in a bowl until no more appears and the area around the hole(s) is dry. Remove any paint from the area using an abrasive paper or wire brush, I use a rotary wire brush in the end of a drill.

Ensure that the area is free from loose particles and grease, isopropyl alcohol will remove the grease.

Cut equal length pieces from the epoxy putty and mix together.

A good way to mix is to squash the two pieces together. flatten and fold it. Mixing is then accomplished by folding the putty over and over again, approximately 40 times to get a good mix. When mixed you then have a good half hour to work with it.

The putty is very sticky and provided you have degreased properly and the area to be repaired is dry a good fix is easily attained. Press the putty onto the leaking area and smooth down the edges as shown in the photograph.

Leave a good 12 hours or until the putty is rock hard.

Open the radiator valve and check for leaks.

The repair in the photograph above was performed in 2014 and with still no sign of a leak.
