Store the heater in a dry place during the summer months. Wrap the cord loosely to avoid internal damage. Regular maintenance ensures it performs efficiently when you need it most.
Frequently Asked Questions
Are energy efficient space heaters worth the investment?
Yes, they are worth the investment as they reduce electricity bills by optimizing heat output. Models with ECO modes adjust automatically to maintain temperature. This means you pay for what you use rather than running at full power.
How do I choose the right wattage?
Select wattage based on your room size. A 1500W heater is usually sufficient for rooms up to 250 square feet. Larger spaces may need multiple units or higher wattage models for effective heating.
Can I leave the heater on all night?
It is safe to leave them on all night if they have safety features like overheat protection. Many models have timers or auto-off functions. Always follow the manufacturer guidelines for extended use.
Do space heaters dry out the air?
Oil-filled heaters are less drying as they retain heat without blowing air. Ceramic heaters can dry the air slightly but usually not enough to be noticeable. Using a humidifier can help maintain comfort.
What is the best heater for a bedroom?
Look for a heater with low noise levels like 30dB or less. Models with remote controls and auto-off timers are ideal. Safety features like tip-over protection are also essential for bedroom use.
