When your radiators are warm at the top but cold at the bottom, it can be frustrating and uncomfortable. This uneven heating usually means something is stopping hot water from flowing properly through the system. Left unresolved, it can make your home harder to heat, push up energy bills, and even cause long-term damage to your boiler.
At The Sussex Heating Care Company, we offer boiler services in Bognor Regis, Chichester, and Littlehampton to resolve these issues quickly and effectively.
Why Radiators End Up Cold At The Bottom
Sludge Build-Up In The Radiators
One of the most frequent reasons is sludge. Over time, rust, dirt, and debris settle at the bottom of your radiators and stop hot water from circulating evenly. We can carry out a professional power flush to clear this build-up and restore full heat output.
Trapped Air In The System
Although air usually affects the top of radiators, it can sometimes cause uneven heating all around. If bleeding the radiator doesn’t solve the problem, our heating engineers can check your system for wider issues that may be causing air pockets to form.
Problems With The Pipework Or Pump
Sometimes the problem is deeper in the system. A partial blockage in the pipes or a faulty pump attached to your boiler can reduce water flow. Our engineers can inspect the boiler and pipework, carrying out any repairs or adjustments needed to get your heating running smoothly again.
Boiler-Related Issues
Your boiler works hard to circulate hot water around your home. If it hasn’t been serviced for a while, worn parts or efficiency issues may cause radiators to heat unevenly. That’s why we recommend annual boiler servicing in Bognor Regis, Chichester, and Littlehampton. Our team can spot potential issues early and make sure your boiler is working at its best.
