Buying Guide
FAQs
What is the most important factor to consider when choosing a smart heater?
The primary factor is heating capacity, which should match the size of your room. Check the product’s wattage and recommended square footage to ensure it can effectively warm your space without being overpowered or underpowered.
How do smart space heaters differ from regular space heaters?
The main difference is connectivity, allowing you to control the heater remotely via a smartphone app or voice commands through smart assistants like Alexa or Google Assistant. This enables features like scheduling, temperature adjustments from anywhere, and integration into your smart home routines.
Are smart space heaters more expensive to run?
No, a smart heater does not inherently use more electricity than a standard one with the same wattage. However, their smart features like scheduling and precise temperature control can actually save you money by preventing the heater from running unnecessarily.
What safety features should I look for in a smart space heater?
Prioritize heaters with essential safety features like overheat protection, which automatically shuts the unit off if it gets too hot. A tip-over switch is also crucial, instantly cutting power if the heater is accidentally knocked over.
What’s the difference between ceramic, infrared, and oil-filled heaters?
Ceramic heaters are great for quickly heating small to medium rooms. Infrared heaters provide instant, directional heat to objects and people, making them ideal for spot heating. Oil-filled heaters are silent and best for maintaining a consistent temperature in larger spaces over a longer period.
Do I need a special hub or device to use a smart space heater?
Most modern smart heaters connect directly to your home’s Wi-Fi network, so you don’t need a separate smart hub. You simply need a smartphone to download the manufacturer’s app for initial setup and control.
How much should I expect to spend on a quality smart space heater?
A reliable and feature-rich smart space heater typically costs between $80 and $200. While cheaper models exist, investing in a reputable brand often ensures better build quality, more reliable connectivity, and superior safety features.
What are the benefits of app control for a space heater?
App control offers unparalleled convenience, allowing you to pre-heat a room before you arrive or turn it off from your bed. It also provides access to advanced features like energy usage tracking, creating detailed heating schedules, and setting precise temperature targets.
