Customer Reviews
Customer Review: “Nothing short of amazing. But remember it’s about BTUs with heaters. You are talking 5200 here. A round kerosene heater is 23,800 BTUs. So if you need that level of heat I suggest kerosene over this. This is supplemental heat. Take the chill off. It’s not meant to heat your whole house like a kerose”
Customer Review: “Best small heater I’ve purchased. This is the 2nd one. The 1st one I bought in 2013, & it just stopped working. Heats up a whole room easily. Haven’t tried to use the humidifier. Looks nice. I would recommend. Somewhat quiet. Easy to move since it is on rollers. Safe around toddlers”

Complete Buying Guide for Best Space Heater for Old Wiring
Essential Factors We Consider
When selecting a space heater for old wiring, safety and efficiency are non-negotiable. We prioritize models with low to moderate wattage (ideally under 1500W), automatic shutoff features, and thermostatic controls to prevent overheating and circuit overloads. Look for heaters with tip-over and overheat protection, ETL or UL certification, and energy-saving modes like Eco settings. Portability, noise level, and ease of use—such as remote controls or digital displays—are also important for daily comfort.

Frequently Asked Questions
Q: Can I use a 1500W space heater on old wiring?
A: Yes—but only if your circuit can handle it. Most older homes have 15-amp circuits, which safely support up to 1800W. A 1500W heater leaves a small buffer, but avoid running other high-wattage appliances on the same circuit.
Q: What safety features should I look for?
A: Always choose heaters with tip-over protection, overheat shutoff, and flame-retardant materials. ETL or UL certification is a must for verified safety standards.
Q: Are ceramic heaters safer for old wiring?
A: Ceramic heaters are generally safer because they heat up quickly and have built-in thermal cutoffs. They’re also more energy-efficient, making them ideal for older electrical systems.
Q: Should I use a space heater with a thermostat?
A: Absolutely. A built-in thermostat prevents the heater from running continuously, reducing power consumption and lowering the risk of overheating—especially important in homes with outdated wiring.
Q: Can I leave a space heater on overnight?
A: Only if it has robust safety features like auto shutoff and tip-over protection. Never leave any heater unattended for long periods, and always place it on a stable, non-flammable surface away from curtains or furniture.
Staying warm in an older home doesn’t have to be a risky or expensive ordeal. With the right space heater, you can enjoy cozy comfort while protecting your home’s electrical system.
