10 Best Space Heaters

The Dyson Purifier Hot+Cool HP1 is a versatile space heater designed for rooms up to around 27 square meters, making it suitable for small to medium-sized living spaces. It stands out by combining powerful heating with air purification, using a fully sealed HEPA H13 filter system that captures 99.95% of tiny allergens and pollutants, which is excellent if you’re concerned about air quality. The heater uses Dyson’s Air Multiplier technology, which delivers smooth airflow to heat a room evenly or cool you down during warmer months, adding year-round value.

In terms of energy use, it operates at 40 watts, which is generally efficient for a device with combined heating and cooling functions. Safety is well covered with an auto shutoff feature, giving peace of mind if the heater is accidentally tipped or left on too long. Noise-wise, it runs at about 63 decibels, which is roughly the sound level of a normal conversation—noticeable but unlikely to be disruptive.

Portability is decent given its height (76.5 cm) and weight (5.26 kg); it’s not the lightest heater but still manageable to move around as needed. Controls are user-friendly, with a curved magnetic remote that docks neatly on the unit and smart app connectivity, allowing you to monitor and adjust settings remotely or via voice commands if you have compatible devices. While the heating capacity is relatively limited compared to larger heaters, making it less ideal for bigger rooms or very cold environments, the combination of air purification and smart features makes the Dyson HP1 a strong contender for those wanting flexible, multi-functional climate control. For straightforward, powerful heating in large spaces, other options might be more suitable.

The Dyson Hot+Cool Jet Focus AM09 serves as both a space heater and a cooling fan, making it a versatile choice for year-round use. Its use of Air Multiplier technology provides a smooth and powerful airflow that can efficiently heat or cool a room. The PTC ceramic plates ensure fast heating and even distribution, which is ideal for maintaining a comfortable environment. Dyson's Jet Focus control is a standout feature, allowing you to switch between focused heating for personal use and diffused heating for the entire room.

The device offers safety features like a bladeless design, reducing risks often associated with traditional fans and heaters. It's designed for indoor use and is relatively portable at 4.31 kg, though its tower form factor might not fit well in very compact spaces.

Noise level might be a drawback for some, as powerful airflow can result in noticeable sound, especially in small rooms. Control options are user-friendly, with adjustable speed and temperature, but it only offers two speed settings, which might not provide the level of customization some users desire.

The Dyson Hot+Cool Jet Focus AM09 is well-suited for someone looking for a multi-functional space heater and cooling fan with advanced airflow technology, though potential buyers should consider its noise level and limited speed settings.

The Dreo Electric Heater is a compact, portable ceramic fan heater designed mainly for indoor use, especially in bedrooms or small rooms. Its 1500W power level is typical for space heaters and should comfortably warm most personal spaces. The heater uses an advanced PTC (Positive Temperature Coefficient) system combined with a smart heat funnel design that spreads warm air more effectively than many traditional models, which means you’ll feel the heat quickly and over a wider area.

One of its standout features is precise temperature control, allowing you to set temperatures between 5°C and 35°C in small steps. This helps save energy by avoiding overheating. It also offers three heating modes: Power heat for quick warming, ECO for energy saving, and a fan-only mode for air circulation without heat. Safety is a strong point here. The heater includes tip-over protection with a sensitive tilt sensor, overheat protection, and flame-retardant materials, making it safer for use around children or pets. Additional safety conveniences include a child lock and a 12-hour timer.

In terms of noise, it’s designed to be very quiet at just 34 dB—about the sound of a whisper—so it won’t disturb sleep or work. Portability is good thanks to its lightweight (1.38 kg) and a built-in handle for easy moving around your home. Controls are user-friendly with a digital display and adjustable settings, including speed and temperature. Features like a mute option and memory function enhance convenience. This heater is intended for indoor use only and may not be suitable for heating large spaces or outdoor areas. While it is energy efficient for its type, running any 1500W heater continuously can still use a fair amount of electricity. Also, some users outside mainland UK may face delivery restrictions. The Dreo Electric Heater is a reliable, safe, and quiet choice for anyone needing a portable room heater with fine temperature control and modern safety features, ideal for bedrooms or small living spaces.
