An Ideal Home report says radiator performance may be affected by dust, trapped air, poor heat circulation and confusing thermostat settings. Experts quoted by the publication recommend routine cleaning, bleeding when symptoms indicate trapped air, and keeping radiators clear; the report does not establish that every cold home has a radiator fault.
An Ideal Home report has outlined several common reasons radiators may not heat a home effectively, citing advice from heating and home-service experts on dust, trapped air, blocked airflow and system settings. The guidance matters as households prepare to use central heating, but it does not identify a single cause for cold rooms or establish that all poorly heated homes have a radiator problem.
Martin Garbutt, head of technical governance at home services platform Ding, told Ideal Home that dust inside radiators can affect their efficiency. He said it may reduce efficiency by up to 10%; the report does not provide the testing conditions or a broader study behind that estimate. Garbutt advises switching a radiator off and letting it cool before removing dust with a vacuum’s narrow nozzle or a hairdryer. A damp towel can catch debris, he said. For exterior surfaces, he suggested warm water with a little dish soap or white vinegar and a microfiber cloth.
Ian Palmer-Smith, a service and repair expert at Domestic & General, said a radiator that is cold at the top and hot at the bottom may have trapped air and need bleeding. Gurgling or banging noises can also indicate air in the system, he told the publication, and he recommends bleeding radiators at least once a year as routine maintenance. The report does not suggest bleeding is necessary whenever a radiator feels cool: the described temperature pattern and noises are the warning signs he identified.
If bleeding does not resolve uneven heating, Ant Langston of HeatandPlumb.com said the system may need balancing. He described adjusting the lockshield valve, which sits opposite the thermostatic radiator valve, to even out the flow of hot water among radiators. Garbutt separately warned that large furniture placed in front of a radiator can obstruct heat circulation. The report also discusses thermostat use, but the supplied material ends before giving the relevant expert advice or specific thermostat instructions.
Small Checks That Affect Room Heat
The advice focuses on problems that can make a heating system seem less effective without necessarily requiring a new radiator. Dust, trapped air and obstructed airflow are presented as possible factors homeowners can check, while persistent uneven heating may need a more technical assessment. Identifying the pattern can help distinguish routine upkeep from an issue that needs professional attention.
That distinction matters because the report also describes a home that remains cold despite central heating, while acknowledging that draughts and poor insulation may contribute. Radiator maintenance cannot by itself confirm or correct those broader building problems. The cited 10% figure is an expert’s estimate reported by Ideal Home, not a guarantee of the savings or improvement any household will see after cleaning.

Preparing Radiators for Cold Weather
The original report was framed around preparing for the cooler months, when households start relying more heavily on central heating. Its author described a draughty, poorly insulated older home that stayed cold even with the heating running, and asked whether radiator upkeep might be part of the problem. That personal experience is the article’s starting point, not a diagnosis of readers’ heating systems.
The report brings together advice from three named professionals: Garbutt on cleaning and unobstructed heat circulation, Palmer-Smith on bleeding, and Langston on balancing. Their recommendations address different possible problems. Cleaning removes dust; bleeding releases trapped air; balancing adjusts water flow. The source does not provide a full step-by-step guide to valve adjustment, nor does it explain the author’s thermostat setup before the supplied text cuts off.
““If your radiator feels cold at the top and hot at the bottom, this means there is trapped air inside of it that is preventing hot water from circulating.””
— Ian Palmer-Smith, service delivery director at Domestic & General, quoted by Ideal Home
Causes of Cold Rooms Remain Open
The report does not establish which issue, if any, is responsible for poor heating in a particular home. Insulation, draughts, boiler performance and radiator condition can all be relevant, but the supplied article does not assess them comparatively or provide diagnostic tests. It also does not state the evidence behind the estimate that dust can cut radiator efficiency by up to 10%.
Details about thermostat settings are missing from the supplied source material, which stops partway through the author’s discussion of a wireless thermostat and thermostatic radiator valves. The report therefore cannot support a specific recommendation about thermostat placement, schedules or target temperatures. It also does not give a full procedure for balancing radiators or explain when a qualified heating professional should take over.
Check Symptoms Before Adjusting Valves
For readers following the report’s advice, the first checks are to keep radiators clear of furniture and dust them only after switching them off and allowing them to cool. A cold top with a warmer bottom, or gurgling and banging, are the symptoms Palmer-Smith associates with trapped air. If bleeding does not resolve uneven heat, Langston’s comments point to a possible balancing issue rather than a confirmed diagnosis.
Homeowners who are unsure how to bleed a radiator or adjust a valve should consult the appliance or heating-system instructions or seek help from a qualified heating professional. If rooms remain cold after basic checks, the underlying cause—including insulation, draughts or a boiler fault—still needs to be identified. The supplied report offers no update or follow-up finding on the author’s own heating system.
Key Questions
What can make a radiator feel as if it is not heating properly?
Ideal Home’s report lists dust, trapped air, blocked airflow and uneven water flow as possible factors. A cold home can also have other causes, including draughts or poor insulation; the report does not diagnose individual systems.
How can I tell if a radiator may need bleeding?
Ian Palmer-Smith said a radiator that is cold at the top and hot at the bottom may contain trapped air. Gurgling or banging noises can also be a sign, according to his advice quoted by Ideal Home.
How often does the report recommend bleeding radiators?
Palmer-Smith recommends bleeding radiators at least once a year as standard maintenance. The report also describes symptoms that may indicate trapped air; it does not provide a system-specific schedule.
Can furniture reduce radiator performance?
Martin Garbutt told Ideal Home that large furniture can trap heat and limit circulation around a room. Keeping the radiator clear may help heat move more freely, but it will not address every possible heating problem.
What if bleeding a radiator does not fix uneven heating?
Ant Langston said a balancing issue may remain if some radiators stay cooler after bleeding and valve settings have been checked. He described the lockshield valve as part of that adjustment, but the report does not include a full procedure; seek qualified help if you are unsure.
