With a heating capacity that quickly warms up spaces up to 270 sq ft, this heater is ideal for those who need fast and effective warmth. The ceramic heater technology ensures energy efficiency, making it cost-effective while maintaining a comfortable environment. Its precise thermostat control, which allows temperature adjustments between 41-95°F with 1°F precision, ensures stable and desired warmth.

Safety is a top priority with this heater, featuring V0 flame-retardant materials, tip-over and overheating protection, and a child lock feature, making it safe for households with children and pets.

However, it does lack some advanced connectivity features like Wi-Fi or smart home integration, which might be a downside for tech-savvy users. Additionally, while the heater offers a good range of heating modes, it may not be the best choice for extremely large spaces beyond 270 sq ft. Its elegant gold color and modern design make it a stylish addition to any room. The Dreo Space Heater is an excellent choice for those seeking an efficient, safe, and quiet space heater for medium to large rooms.

The Dr. Infrared Heater, model DR998, is a 1500W portable heater that boasts several impressive features designed to efficiently heat large rooms. Its dual heating system combines infrared quartz tube and PTC (Positive Temperature Coefficient) heating elements, ensuring effective and even heat distribution.

The electronic thermostat offers a broad temperature range from 50 to 85 degrees Fahrenheit, allowing precise control over your room's climate. The heater also includes essential safety features like tip-over protection and overheat protection, enhancing its safe usage in various settings, including living rooms, bedrooms, and home offices. Additionally, the cool-touch exterior reduces the risk of burns. Portability is another strength of this heater, with its compact dimensions and freestanding design making it easy to move between rooms. However, at 24.8 pounds, it may not be the lightest portable heater available.

Noise levels are generally low, although the oscillation function may produce some sound. The inclusion of a remote control adds convenience, allowing you to adjust settings from a distance.
