Radiator and central heating guides
Uneven heat does not always mean a new radiator or a power flush. These guides connect room requirements, pipework, controls and circulation so a repair or upgrade has a clear purpose.

Articles and fault guides
Heating controls after a power cut: recovering the settings
Check heating clocks, programmes and normal user controls after a power cut, with clear limits for repeated trips, boiler faults and wiring problems.
Read thisReplacing a cast-iron radiator: weight and connections
Plan cast-iron radiator replacement around safe handling, floor or wall support, pipe centres, heat output and access before ordering the new unit.
Read thisChoosing radiator size and heat output
Choose a radiator using room heat loss, operating temperatures and fitting space. Compare output figures before ordering a new radiator style or size.
Read thisHeating checks after a refurbishment
Check altered heating before a refurbishment is signed off. Plan pipework tests, radiator operation, controls and handover between building trades.
Read thisHeating pipe noises at night: expansion or a fault?
Record the timing and location of night-time heating noises to distinguish expansion, flow and control concerns, with clear limits for safe observation.
Read thisHeating pump faults: repair assessment and replacement
Understand heating circulation pump assessment, from controls and flow symptoms to compatible replacement, commissioning and the cause of repeat faults.
Read thisHeating inhibitor: what to check and record
Understand heating-water inhibitor checks, product compatibility, concentration evidence and records after repairs, draining or boiler installation.
Read thisLower boiler flow temperature: a practical guide
Understand lower boiler flow temperatures, radiator output and warm-up time. Check the system type before changing settings that affect stored hot water.
Read thisWhat a heating magnetic filter does and does not fix
Understand heating magnetic filter maintenance, captured debris and its limits, including when water testing, cleaning or a separate repair is needed.
Read thisMoving or adding a radiator during renovation
Plan a radiator move around room heat loss, pipe routes, valves and floor access. Coordinate installation and testing before room finishes are completed.
Read thisWhy heating pipe layout matters before alterations
Understand why one-pipe or two-pipe heating needs identifying before changing radiators, valves or zones, and what a practical survey should establish.
Read thisOpen-vented or sealed heating: planning alterations
Identify open-vented and sealed heating before alterations, with clear distinctions from hot-water cylinders and checks needed before any conversion.
Read thisRadiator balancing or power flushing?
Compare radiator balancing with power flushing before treating uneven heating. Understand the evidence, limits and checks that guide the right next step.
Read thisChanging radiators with pipes in a solid floor
Plan radiator changes over solid floors by checking pipe routes, connection centres, surface routes, safe access and responsibility for finishes.
Read thisTRV, lockshield or manual radiator valve: which part?
Compare thermostatic, lockshield and manual radiator valves by function, connection and system compatibility before ordering a replacement or upgrade.
Read thisWill smart radiator valves fit your heating system?
Check valve bodies, adapters, hub compatibility and heating demand before fitting smart radiator controls, with practical planning for each room.
Read thisCentral-heating, electric or dual-fuel towel rail?
Compare towel-rail options for winter and summer use, room heat, plumbing access and bathroom electrical requirements before choosing a replacement.
Read thisUpgrading heating controls: what to specify
Plan a heating controls upgrade around the boiler, hot water and everyday use. Compare simple scheduling, smart access and compatible room control options.
Read thisZone-valve faults: heating and hot-water symptoms
Understand motorised zone-valve symptoms, why the system layout matters and what professional controls testing should establish before replacing parts.
Read thisZoning an existing central heating system
Explore heating zones for different rooms or floors. Plan controls, pipework and boiler demand before adding smart radiator controls or new zone valves.
Read thisRadiator cold at the bottom: causes and next steps
A radiator cold at the bottom can point to restricted circulation or deposits. Learn what to observe safely and when cleaning or a repair needs assessment.
Read thisRadiator leaking from the valve: what to check
A radiator valve leak needs the source checked before repair. Learn what to observe safely, when to stop the heating and what a repair can involve.
Read thisRadiator not heating up: one room or the whole system?
Radiator not heating up? Compare rooms, check ordinary heating controls and identify what to report before replacing valves or booking system cleaning.
Read thisTRV stuck or not working: what to check
A stuck TRV can leave a radiator cold or too hot. Check normal controls safely, understand other possible causes and know when a valve needs repair.
