The Dreo Space Heater is a compact and portable electric heater designed for indoor use, ideal for rooms up to 200 square feet such as bedrooms, home offices, or kitchens. It uses a 1500W PTC ceramic heating element, which heats up quickly and efficiently, helping warm your space faster than many traditional models. Its heating capacity is suitable for small to medium rooms, making it a solid choice if you want targeted, energy-conscious warmth.

This heater stands out with strong safety features including tip-over protection with a tilt sensor, overheat protection, and flame-retardant materials—all certified by ETL. These features provide peace of mind, especially in homes with children or pets. The adjustable thermostat allows precise temperature control between 41°F and 95°F, which helps save energy by only using as much heat as needed. Noise is kept to a minimum at just 34 dB, thanks to a quiet brushless DC motor and special fan design, so it won’t disturb your sleep or work. Portability is another plus; the heater is lightweight (around 3 pounds) and has a handle for easy carrying from room to room.

Additional conveniences include a remote control, a 12-hour timer, child lock, and multiple heating modes (Power, ECO, Fan Only), giving you flexibility in how you use it. One possible downside is that it’s best suited for smaller spaces and won’t effectively heat larger rooms or open areas. Also, it runs on standard household voltage and may slightly increase your electricity bill if used for long periods. Assembly isn’t required, and customer support is available if you have any questions. This makes the Dreo Space Heater a user-friendly, safe, and quiet option for those seeking efficient heating in compact indoor spaces, especially bedrooms or offices where peace and precise temperature control matter.

Lasko Oscillating Digital Ceramic Tower Heater for Home with Adjustable Thermostat, Timer and Remote Control, 23 Inches, 1500W, Silver, 755320, 8.5″L x 7.25″W x 23″H, Silver

The Lasko Oscillating Digital Ceramic Tower Heater is a solid choice for those looking to efficiently heat small to medium-sized rooms, such as bedrooms or home offices. With a heating capacity of 1500 watts, it provides enough warmth for various indoor settings. One of its key features is energy efficiency, which helps keep electricity bills manageable while still delivering reliable heat.

This heater includes two quiet heat settings and an adjustable thermostat, allowing users to customize their heating experience easily. The optional oscillation feature is particularly useful, as it helps distribute warm air evenly across the room, enhancing comfort. Safety is a priority with this heater, featuring built-in protections like overheat prevention and a cool touch exterior, ensuring safe use even after extended operation. Additionally, the fully assembled design allows for quick setup—just plug it in and you're good to go. The remote control adds convenience, enabling users to adjust settings from across the room.

The programmable timer, which can be set from 1 to 8 hours, adds flexibility for users who want to manage heating times effectively. However, there are a couple of minor drawbacks to consider. While it is quiet for a space heater, some users may still notice noise from the fan, especially on higher settings. Also, its heating coverage is limited, so it may not be ideal for larger open spaces.

Buying Guide for the Best Energy Efficient Space Heaters

Choosing the right energy-efficient space heater can make a significant difference in your comfort and energy bills during the colder months. The key is to understand the various specifications and features that can impact the heater's performance and efficiency. By focusing on these aspects, you can find a heater that meets your needs while being cost-effective and environmentally friendly.
Heating Capacity (BTUs)Heating capacity, measured in British Thermal Units (BTUs), indicates how much heat a space heater can produce. This is important because it determines the size of the area the heater can effectively warm. For small rooms, a heater with 5,000 to 10,000 BTUs is usually sufficient. Medium-sized rooms may require 10,000 to 15,000 BTUs, while larger spaces might need 15,000 BTUs or more. To pick the right one, consider the size of the room you want to heat and choose a heater with an appropriate BTU rating.
Energy EfficiencyEnergy efficiency refers to how well a space heater converts energy into heat. This is crucial for reducing energy consumption and lowering utility bills. Look for heaters with an Energy Star rating or those that mention high energy efficiency in their specifications. To navigate this, consider heaters with features like programmable thermostats, energy-saving modes, and timers, which help optimize energy use. Choose a heater that balances efficiency with your heating needs to ensure you get the most out of your energy consumption.
Type of HeaterThere are several types of space heaters, including convection, radiant, and fan-forced heaters. Convection heaters are good for heating entire rooms evenly, while radiant heaters are ideal for spot heating as they warm objects and people directly. Fan-forced heaters use a fan to distribute heat quickly but can be noisier. To pick the right type, consider how you plan to use the heater. For whole-room heating, a convection heater might be best. For personal or localized heating, a radiant heater could be more suitable.
Safety FeaturesSafety features are essential to prevent accidents and ensure safe operation. Important safety features include overheat protection, tip-over switches, and cool-to-the-touch surfaces. Overheat protection shuts off the heater if it gets too hot, while tip-over switches turn off the heater if it falls over. Cool-to-the-touch surfaces prevent burns. When choosing a heater, prioritize models with these safety features, especially if you have children or pets, to ensure safe use in your home.
Noise LevelNoise level is an important consideration, especially if you plan to use the heater in a bedroom or office. Some heaters, particularly fan-forced models, can be quite noisy, while others, like oil-filled radiators, operate almost silently. To navigate this, check the product specifications or user reviews for noise level information. Choose a heater with a noise level that won't disrupt your activities or sleep, ensuring a comfortable and quiet environment.
PortabilityPortability refers to how easy it is to move the heater from one room to another. This is important if you need to use the heater in different areas of your home. Features that enhance portability include wheels, handles, and lightweight designs. To pick the right one, consider how often you'll need to move the heater and choose a model that offers convenient portability features to suit your lifestyle.
