10 Best Space Heaters 2026 in the United States

The Dyson PureHot + Cool is a versatile device combining a space heater, air purifier, and fan in one unit. It uses a powerful HEPA filter that captures 99.97% of tiny particles like allergens, dust, and smoke, making it a good choice if you want cleaner air along with heating. The heater can warm up rooms up to around 800 square feet and projects heat evenly thanks to its Air Multiplier technology. It also has a real-time pollution monitor and can be controlled via an app, which adds convenience and precise temperature control.

Safety features include automatic detection of air quality and a sealed filter system. Dyson claims it operates quietly, especially in purifier mode, which is nice for bedrooms or offices. The unit weighs about 12 pounds and stands around 30 inches tall, so it’s somewhat portable but not very compact. The main downside is that its price and complexity might be more than what a simple space heater user needs, especially if air purification isn't a priority. Also, since this model is refurbished, some users may prefer a brand-new unit for peace of mind.

This product is well-suited for those who want a combination of clean air and heating with smart features, rather than just a straightforward heater.

The Dyson Hot+Cool AM09 is a unique tower heater that uses a bladeless design, making it safe and easy to clean compared to traditional heaters with visible fan blades. It provides both heating and cooling, making it convenient as a year-round device. The heater uses radiant technology combined with forced air to quickly warm a room such as a bedroom or home office. It operates on standard electric power (120 volts) and offers two speed settings, allowing control over heat output and airflow.

A built-in thermostat helps maintain a steady temperature, which improves comfort and energy efficiency by preventing overheating. The device tends to be quieter than many conventional heaters, thanks to its bladeless motor design, which reduces noise. Portability is reasonable—the unit weighs about 7.85 pounds and stands upright as a floor-mounted tower, making it relatively easy to move, though it is not as light as some compact heaters.

Safety features include the bladeless design, which reduces the risk of burns or injuries. The Dyson AM09 comes with a 90-day warranty, which may be a consideration for long-term reliability. Its price is generally higher than basic space heaters due to its advanced design and brand reputation. This model suits those looking for a stylish, quiet, and safe heater with both heating and cooling functions, while budget-conscious buyers or those needing to heat larger spaces might prefer more affordable or higher-capacity alternatives.

The Rinnai EX38DTP is a propane-powered, direct vent wall heater designed primarily for indoor use. With a strong heating capacity of 36,500 BTUs, it can comfortably warm spaces up to about 1,600 square feet, making it suitable for bedrooms, home offices, or garages. The heater uses forced-air heating, providing fast and consistent warmth without cold spots thanks to its advanced modulating technology. It features a programmable thermostat that can be controlled via Wi-Fi, allowing you to customize temperatures easily for your comfort and convenience.

Safety is well addressed, with a cool-to-the-touch cabinet and built-in self-diagnostic electronics that help ensure safe operation, which is a plus for families with children. The unit is designed to be energy efficient by adjusting fuel use precisely based on heating needs, helping reduce propane consumption and save on energy bills. It operates quietly, which is ideal for living areas where low noise is preferred. However, as a wall-mounted unit weighing 108 pounds, it isn’t portable and requires professional installation, so it’s best suited for those wanting a permanent heating solution rather than a movable heater.

Its compact, beige design fits well in modern homes without taking up floor space. While it excels in efficiency and safety, it’s important to note it runs on propane and needs venting, so it might not be the best choice if you’re looking for an electric or portable option. For those seeking a reliable, efficient, and quiet wall-mounted propane heater with smart features, the Rinnai EX38DTP is an excellent candidate.
