Quality radiators balance heat output (measured in BTU or watts), build durability, and finish. Cast iron and steel radiators offer superior heat retention and longevity—cast iron can last 50+ years if maintained, whilst modern steel radiators are lighter and faster to heat. Check the pressure rating (typically 10 bar for domestic use) and ensure the radiator has a robust valve connection. For electric heaters, look for thermostatic controls, overheat protection, and energy efficiency ratings; halogen and oil-filled models retain heat longer than fan heaters but take time to warm up. Powder-coated finishes resist rust better than basic paint, and welded seams should be smooth with no visible gaps.
Material quality directly impacts performance: thin-walled radiators may warp under pressure, whilst thicker construction maintains shape and efficiency. Verify the radiator has been pressure-tested and comes with a manufacturer's warranty (typically 5–10 years for quality units). For electric heaters, ceramic or mica elements distribute heat more evenly than basic wire coils. Always check the heat output specification matches your room size—undersized radiators waste energy and leave you cold, whilst oversized units are expensive to run.

Common questions about radiators & heaters
Convection heaters warm air, which circulates around your room—ideal for even heating in larger spaces. Radiant heaters emit infrared warmth that heats objects and people directly, making them perfect for spot heating small areas or draughty corners. Radiant units feel warmer faster but don't heat the whole room as efficiently. For UK homes, a combination approach works best: radiant for targeted warmth, convection for general background heating.
