A space heater is a portable device designed to heat specific areas or rooms, offering a flexible alternative to central heating systems. Unlike whole-house heating, which can be energy-intensive, space heaters focus on warming the spaces you actually use, making them ideal for bedrooms, offices, or chilly corners of your home. They work through various mechanisms—convection (warming air), radiant heating (directly heating objects), or a mix of both—and come in electric, oil-filled, ceramic, and infrared models. While they’re praised for their efficiency and portability, safety remains paramount, with modern models incorporating features like tip-over shutoffs and overheating protection.
Having personally used an oil-filled radiator, I learned that not all heaters are created equal. My unit struggled to efficiently warm a 30 sq meter living room, but newer models, like the Pelonis Oil Filled Radiator (reviewed below), promise improved performance. Below, we break down six top-selling space heaters on Amazon UK (as of February 2025), analyzing their features, pros, cons, and ideal users.
Types of Space Heaters: A Quick Overview
Before diving into product reviews, let’s explore the main types of heaters and their strengths:
| Type | How It Works | Best For | Pros & Cons |
|---|---|---|---|
| Ceramic | Uses ceramic plates and a fan to blow warm air. | Quick heating, small spaces | ✅ Lightweight, fast heat. ❌ Can dry air, noisy fans 19. |
| Oil-Filled | Heats oil inside sealed columns; radiates warmth slowly. | Consistent, long-lasting heat | ✅ Silent, retains heat. ❌ Heavy, slow to warm up 28. |
| Infrared | Emits infrared rays to heat objects/people directly. | Instant spot heating, energy efficiency | ✅ Quiet, no dry air. ❌ Limited range, cools quickly 47. |
| Fan Heaters | Blows air over heated coils. | Rapid warmth, affordability | ✅ Compact, budget-friendly. ❌ Noisy, less efficient 510. |
