Dragon 4 Pro

UPGRADE

Ten oil-filled elements deliver gradual, fanless heat with useful warmth after switch-off. Its 2,500W ceiling and three power levels suit larger European rooms, but the heavy chassis heats more slowly than forced air.

WHY THE PRICE IS JUSTIFIED

The 2,500 W rating, 10-element oil-filled construction, three power levels, electronic controls, ECO Plus and residual heat support room heating rather than merely appearance. Which? lists programmable temperature control, tip-over shutoff and overheating protection, while its testing notes that oil-filled heaters continue releasing heat after switch-off.

IDEAL FOR

  • ·Heating larger rooms up to the stated 75 m³ capacity
  • ·Users wanting programmable electronic controls and ECO Plus
  • ·Rooms where gradual residual heat is useful
  • ·Users needing wheels, handles and cable storage

  • ·Buyers seeking independently measured thermostat or noise performance

DESIGN & ERGONOMICS

A tall radiator form with soft castors, two upper lip handles, integrated cable storage and a digital control interface. The tower design is intended to distribute warm air consistently, while the oil reservoir provides gradual residual heat.

LONGEVITY

The official page states full manufacturer warranty coverage, but the supplied sources do not specify its duration, expected lifespan, repairability or spare-parts availability. The oil-filled design continues releasing heat after switch-off, but that is not a lifespan claim.
