5 Best Space Heaters for Large Rooms (with High Ceilings)
Some homes develop cold spots. The cold spot in your home may be a large room with high ceilings that your HVAC system can’t manage to keep warm. Finding the best space heater for a large room with high ceilings can be a challenge
Sizing a space heater for a large room with high ceilings is more about volume than simple floor space. You must heat the volume of air in the room to gain warmth. Smaller space heaters can’t move enough air or generate enough heat to achieve a comfortable temperature. Our list of best space heaters for larger rooms with high ceilings considers air movement and room volume.
| Heater Make and Model | Type of Heating Element | Air Handling Method | Where is this Heater Best Used? |
| Zhihe Space Heater, PTC 2000w Portable Ceramic with Oscillating Fan | Ceramic | Forced Air Oscillating Fan | Rooms larger than 10 ft by 10 ft with ceilings higher than 10 ft |
| Costway 5 in 1 Ceramic Heater and Air Cooler | Ceramic | Forced Air Fan | Multi-function design heats, cools, and humidifies in one unit. for areas where both heating and cooling are needed |
| Lasko 5775 Electric 1500w Ceramic Space Heater | Ceramic | Forced Air Oscillating Fan | Rooms smaller than 10 ft by 10 ft with ceilings between 8 and 12 feet high |
| Honeywell 360 Degree Surround Heater with Fan Forced Technology | Ceramic | Forced Air Fan with 360 Degree Technology | Smaller rooms with high ceilings up to 1200 cubic feet where directional fans won’t work |
| Stiebel Eltron 074057 240-Volt 2000-Watts Wall Mounted Electric Fan Heater | Nichrome Wire | Downdraft Forced Air | Wall mount technology eliminates free-standing space heaters |
Sizing a heater for air volume in a room that needs to be heated ensures that the heater operated efficiently and effectively. Heaters that are too small for the volume of air will run continuously. Heaters too large for a given volume of air will tend to cycle on and off quickly. This constant cycling is hard on the heater and inefficient. Let’s look at our heater choices.
1. Best Space Heater for Extreme Rooms – Zhihe Space Heater, PTC 2000w Portable Ceramic with Oscillating Fan
Many larger homes feature entertainment areas of gathering areas with large square footage and extremely high ceilings. Rooms with vaulted ceilings with loft areas fit in this category. Typically, rooms with a total volume over 1,400 cubic feet need a space heater of at least 2,000 watts.
The Safety Challenge
The Zhihe space heater fits this bill perfectly. Dual wattage allows you to run this heater at the full 2,000 watts or select the 1,300 watts setting for more efficient operation. Zhihe incorporates a full suite of safety features as well as the latest technology in ceramic heating. Safety is always a primary concern when using electric space heaters, and Zhihe offers the finest safety features.
