Experience safe, sustained, and whisper-silent whole-room warmth with the Alva Premium Oil-Filled Column Heater range. Engineered without complex timers for straightforward, plug-and-play reliability, these high-performance radiators utilize advanced thermal oil technology to distribute heat evenly across your living spaces.
Unlike standard fan heaters that dry out the air and create distracting ambient noise, Alva oil heaters work through natural convection. The internal heating elements safely warm the permanently sealed thermal oil, which circulates through the columns to project deep, long-lasting radiant heat that continues to warm your room even after the unit cycles off. Available in 9-Fin, 11-Fin, and 13-Fin configurations, this range offers the perfect thermal footprint for any room size, from compact home offices to expansive, open-plan living areas.
