Frequently Asked Questions
Why is my radiator cold at the bottom but hot at the top?
When a radiator is cold at the bottom, black iron oxide sludge (magnetite) has settled in the lower channels, blocking hot water circulation. Depending on severity, we either replace the corroded radiator or perform a chemical power flush.
Why is one radiator completely cold while others are hot?
A single cold radiator is usually caused by a stuck Thermostatic Radiator Valve (TRV) pin, an airlock, or an unbalanced heating circuit where radiators closer to the boiler steal all the flow.
Do you install customer-supplied designer radiators?
Yes. We regularly fit vertical designer radiators, traditional cast-iron column radiators, and heated towel rails supplied by homeowners, ensuring wall brackets and pipe centers are reinforced properly.
Will replacing a leaking radiator valve fix my boiler pressure drop?
Yes. Even a slow, barely visible weep on a radiator packing gland or lockshield valve will cause a sealed gas boiler to lose pressure and lock out repeatedly.
