Is Your Radiator Not Working Properly?
Is your radiator cold at the top and warm at the bottom or vice versa? Is one radiator not heating while the others work fine? If your radiator is not heating up, or you constantly find yourself bleeding radiators, you’re not alone. Many homes across Dublin experience common heating radiator issues, and in most cases, they’re simple to fix if you know what you’re doing.
At Stillorgan Gas, Plumbing & Electrical, we specialise in home radiator repair, radiator replacements, power flushing, and new radiator installations. With a team of over 40 skilled engineers and heating specialists, we provide reliable, local radiator services across Dublin and surrounding areas.
Common Radiator Problems We Fix
Radiators play a vital role in keeping your home warm and comfortable—especially during cold Irish winters. But over time, they can suffer from a range of issues. Our expert heating engineers are trained to identify and solve radiator problems quickly and efficiently.
Here are some of the most common radiator issues we repair:
-
Radiator cold at the top or bottom
-
Radiator not heating at all
-
Demand on Bleeding Radiators
-
Leaking radiator valves or joints
-
Radiator making banging or gurgling noises
-
Radiators heating unevenly
-
Sludge build-up inside radiators
-
Air trapped in the system
-
Thermostatic radiator valve (TRV) failure
-
Poor radiator balancing across multiple rooms
No matter the issue, we’ll diagnose the problem quickly and advise on the best, most cost-effective solution.
Power Flushing Radiators – A Smart Heating Investment
If your radiators are slow to heat or constantly cold at the bottom, they may need a radiator power flush. Over time, rust, limescale, and sludge build up and restrict water flow—making your heating less efficient and more expensive to run.
What Is a Radiator Power Flush?
A power flush uses high-pressure water and specialised cleaning chemicals to remove sludge and debris from your central heating system.
Power Flushing Benefits:
-
Boost radiator heat output
-
Lower heating bills
-
Extend the life of your heating system
-
Prevent frequent radiator bleeding
-
Reduce boiler strain
-
Heat your home faster
Power Flush Cost in Ireland depends on your system size and number of radiators.
