Radiator Plasterboard Fixings - GeeFix
Gary Williams, a retired plumber with over 30 years of experience, invented GeeFix. We take pride in the fact that we designed and developed it in the UK, and it is manufactured in Shropshire, supporting local industries.
He created GeeFix to secure heavy items to plasterboard and drywall walls. Modern homes often use studwork and plasterboard, making GeeFix the ideal choice for mounting heavy objects, such as TVs, radiators, towel rails, shelving, cabinets, cupboards, mirrors, and curtain rails.
These fixings are also great for reattaching objects to plasterboard when other types have failed. For example, if a radiator pulls away from the wall, you can install a GeeFix anchor in the same spot as the old one, often reducing the repair work needed on the plasterboard.
Additionally, GeeFix adapts well for smaller items, like bathroom accessories, where fixing holes are close together. In these scenarios, you can use one fixing to secure the item by leveraging the backplate’s length for extra support.
So if you are wondering what are the best plasterboard fixings for radiators, the answer is GeeFix without a doubt. They are the strongest plasterboard radiator fixings on the market.

Fixing Radiator to Plasterboard
How to hang a radiator on a plasterboard wall using GeeFix. You can hang a radiator on plasterboard easily with GeeFix using the instructions below:

Step 1
Drill a 1” hole centered on your desired location

Step 2
Assemble your GeeFix wall anchor system as shown above by threading the supplied blue pullcord through the round wall plug, the curved back plate, and back through the wall plug.

Step 3
While holding onto the pullcord, feed the curved back plate into the hole and center on the 1″ hole

Step 4
While keeping light tension on the pullcord slide the wall plug into the 1″ hole to align with the holes on the back plate

Step 5
While keeping firm tension on the pullcord, screw the large screw into the center hole until the GeeFix becomes firm, but do not overtighten. Keeping tension on the pullcord will keep the back plate in place during installation.

Step 6
Pull out the pullcord but do not discard. You can use the same pullcord on additional GeeFix installations.

Step 7
Insert the 2 smaller screws on either side of the large screw and tighten until the GeeFix is firmly secured but do not overtighten.

Step 8
Remove the center screw

Step 9
Now that your GeeFix system is installed, you can either use the center screw to fix your item, or use your own mounting hardware in its place.
Challenges of Mounting Radiators on Plasterboard
Attaching a radiator directly to plasterboard can lead to several potential problems, primarily due to the material’s structural limitations and heat sensitivity. Here are some of the key issues you might encounter:
Weight Bearing Capacity
Plasterboard, also known as drywall or gypsum board, is not designed to support heavy loads. Radiators can be quite heavy, especially when filled with water, and mounting them directly onto plasterboard can lead to structural damage. Over time, this can cause the plasterboard to sag or even fail, potentially causing a safety hazard.
Heat Conductivity
Plasterboard is a relatively poor conductor of heat. When a radiator is attached directly to it, the heat generated by the radiator might not be efficiently distributed throughout the room. This can lead to uneven heating, with areas closer to the radiator being significantly warmer than those farther away.
Risk of Fire
While plasterboard is fire-resistant to some degree, it is not completely fireproof. Directly attaching a radiator can potentially increase the risk of fire if the radiator becomes too hot and the plasterboard is not adequately insulated or protected.
Thermal Expansion and Contraction
Radiators undergo significant temperature fluctuations as they heat up and cool down. Plasterboard is not designed to withstand these extreme temperature changes without some form of reinforcement or insulation. Over time, this can lead to cracks or other forms of damage in the plasterboard.
Fixing Points and Brackets
Attaching a radiator securely to plasterboard requires special consideration. Traditional wall plugs and screws might not provide enough support. Specialized brackets or anchors designed for plasterboard are needed, and even then, they may not provide the same level of stability as mounting on a solid wall.
Moisture Absorption
In areas where moisture levels are high, such as bathrooms, kitchens, or laundry rooms, plasterboard can be susceptible to damage. Mounting a radiator directly onto plasterboard in such environments can exacerbate this issue, potentially leading to mold growth, warping, or deterioration of the plasterboard.
To mitigate these problems, it’s advisable to install radiators on a solid, load-bearing surface, such as a brick or concrete wall. If attaching a radiator to plasterboard is unavoidable, consider using additional measures like spreading the load with a large piece of plywood or using specialized fixings designed for this purpose. It’s also crucial to consult with a professional installer or contractor to ensure that the installation is carried out safely and securely.
