Common Radiator Problems We Fix
Radiators can develop faults over time that affect heat output, safety, and efficiency. At The Heat Network, we’ve seen it all—and fixed it all. Here are some of the most common radiator issues we deal with:
Radiators not heating up
If a radiator stays cold while others in the house are hot, it’s often caused by trapped air, a stuck valve, or poor system balance. We’ll diagnose it quickly and get the heat flowing again.
Leaking or noisy radiators
Leaks often come from old valves, corroded joints, or failing seals. Noises like banging or gurgling usually point to air or sludge inside the system. We’ll sort both on the spot.
Loose or rusty radiators
Radiators can become loose from the wall over time or develop rust due to slow leaks. We’ll safely secure or replace them and check for underlying issues to stop it happening again.
Repair or Replace? We’ll Advise Honestly
We don’t believe in upselling. If your radiator can be repaired safely and cost-effectively, that’s what we’ll do. If replacement makes more sense—due to age, condition, or efficiency—we’ll explain why and show you the options.
We supply and fit a wide range of radiators, from standard panels to designer and vertical styles, all matched to your room’s heating needs.

Radiator Cold at the Bottom? Here’s Why
A radiator that’s hot at the top but cold at the bottom usually has a sludge problem. Over time, rust and debris settle in the lower part of your system, blocking hot water from circulating properly.
We can perform a system check and recommend the right solution—whether that’s a radiator flush, valve replacement, or full system clean using our Thoroughflush or MagnaCleanse equipment.
