BLACK+DECKER Portable Space Heater
Type: Compact PTC/fan heater with two heat levels and fan mode. Energy Features: Offers a LOW HEAT (750W) setting and a high 1500W setting, enabling lower electricity consumption when full power isn’t required.
The unit is portable and lightweight, making it suitable for spot heating at a desk, bedside, or small room. The adjustable thermostat control with two heat levels lets users select a reduced-wattage option for lower energy use. Built-in carry handle and 6 ft. cord improve placement flexibility, which can reduce energy waste if you place it close to the occupied area.
Dreo Space Heater With Precise Thermostat
Type: 1500W PTC ceramic heater with digital display, remote, and 12-hour timer. Energy Features: Precise thermostat control from 41–95°F in 1°F increments, multiple modes, and timer functions to limit runtime.

This Dreo model emphasizes accurate temperature control using an NTC chipset that can reduce cycling and overshooting—important for energy savings. The fast PTC ceramic heating design reaches set temperatures quickly, then cycles to maintain them. Built-in timer and remote help avoid running the heater longer than needed, and safety features allow unattended, energy-efficient operation within designed limits.
Dreo Space Heater With 70° Oscillation
Type: 1500W PTC ceramic heater with 70° oscillation and 5 modes. Energy Features: Oscillation and efficient fan wheel design aim to spread warm air farther and reduce run time needed to heat a space.
By distributing warm air across a wider angle, this heater can create a more uniform room temperature, potentially shortening the period the unit must run at high power. It includes a 12-hour timer, overheat protection, and a smart tip-over sensor. Noise-reducing airflow improves comfort while allowing lower fan speeds to maintain warmth efficiently.
PELONIS Oil Filled Radiator With ECO Mode
Type: Oil-filled radiator with three heat settings (600W/900W/1500W) and an ECO mode claimed to save up to 40% energy. Energy Features: Lower wattage settings and stored-heat design reduce electricity spikes and maintain room warmth after the element cycles off.

Oil-filled radiators rely on thermal mass; they heat the oil and radiate warmth for longer periods without continuous high power. The multiple watt settings let you choose a lower power draw for energy-sensitive situations, and the ECO mode optimizes cycles to maintain comfort while reducing energy use. This approach is especially effective for sustained background heating in medium to large rooms.
VOCRS 1500W PTC Electric Heater With Multiple Modes
Type: Compact PTC ceramic heater offering 700W/1000W/1500W settings, digital display, remote, and 1–12 hour timer. Energy Features: Low- and mid-wattage options and a timer help limit electricity use while providing targeted heat.
The VOCRS unit supports staged heating with lower watt modes that consume significantly less electricity than full power. The timer and remote let users run the heater only as long as needed. PTC ceramic elements also provide quick heat-up and controlled cycling, which can be more energy-efficient when heating occupants rather than entire spaces.
Buying Guide: How To Choose A Low-Electricity Space Heater
When selecting a space heater that minimizes electricity use, focus on technology, controls, and how you plan to use the unit. The right combination reduces runtime and energy waste while maintaining comfort.
1. Heater Type Matters
- PTC Ceramic Heaters: Heat up quickly and cycle off when set temperature is reached. Good for short bursts and spot heating.
- Infrared / Quartz Heaters: Warm people and objects directly, often perceived as efficient for close-range heating without needing to heat the whole room.
- Oil-Filled Radiators: Use thermal mass to radiate heat long after the element turns off, ideal for steady background heat with lower peak power use.
2. Wattage Options And Power Settings
Heaters with multiple wattage settings (e.g., 700/1000/1500W) let you choose lower power draw for energy savings. A dedicated low-watt option (750W) is useful for desks or small rooms.
3. Thermostat Precision And Controls
An accurate thermostat reduces cycling inefficiencies. Digital controls with 1°F increments or ECO modes help maintain a steady temperature and avoid unnecessary run time. Timers and remote controls further reduce wasted electricity by preventing prolonged operation.
4. Distribution And Coverage
Oscillation or wider-angle distribution can warm a space more evenly, shortening how long the heater must run. Match the heater’s coverage claim to your room size; oversized devices may waste energy if they run unnecessarily high to heat small zones.
5. Safety Features That Affect Usage
Tip-over protection, overheat shutoff, and ETL or UL certification permit safer unattended use, letting you rely on timers and automated controls rather than manual monitoring, which can reduce runtime and energy use.
6. Run-Time Strategies
- Spot Heat When Possible: Heat the area where people sit rather than the whole room.
- Use Lower Watt Modes: Start at a low setting and increase only if needed.
- Combine With Insulation: Draft reduction and rugs raise perceived warmth and reduce heater runtime.
7. Compare Long-Term Efficiency
Consider how often and how long you’ll run the heater. Lower-watt heaters used for extended periods may still consume less total energy than a higher-watt unit used intermittently, depending on cycling behavior and set temperature.
Tips for Getting the Best HVAC Prices
- Prioritize Quality Over Cost
The most critical factor in any HVAC project is the quality of the installation. Don’t compromise on contractor expertise just to save money. - Check for Rebates
Always research current rebates and incentives — they can significantly reduce your overall cost. - Compare Multiple Quotes

Once you've chosen a contractor, use the proven strategies from our guide — How Homeowners Can Negotiate with HVAC Dealers — to get the best possible final price.
8. Practical Considerations
- Noise: Quieter units are better for bedrooms, allowing lower fan speeds and more efficient operation overnight.
- Portability: A lightweight heater placed close to occupants reduces the need for higher power.
- Warranty & Reviews: Look for reliability to avoid replacement-related environmental costs.
