What Is an Electric Heater? Everything You Need to Know About
Introduction
When chilly weather sets in or your central heating underperforms, electric space heaters offer targeted warmth in individual rooms. In this guide, we’ll explain how they work, compare heater types, highlight essential safety measures, and provide energy-saving tips to help you choose the best option.
How Do Electric Heaters Work?
Electric heaters generate heat through Joule heating—electricity passes through a resistive heating element, which transforms electrical energy into heat. This heat then warms up air, objects, or surfaces in the room, depending on the heater’s design.
Some models include a built-in fan to blow heated air throughout the space, while others radiate warmth without airflow.
Types of Electric Space Heaters
1. Fan-Forced / Ceramic Heaters
These use a heated ceramic plate or metal coil along with a fan to blow warm air into the room.
Pros: Heats up quickly, great for small or medium-sized rooms
Cons: May dry out the air and generate noise
2. Infrared / Radiant Heaters
These emit infrared radiation to directly warm people and objects in their path, much like sunlight.
Pros: Silent operation, immediate warmth
Cons: Only effective in direct line of sight
3. Oil-Filled Radiators
These heaters contain thermal oil that’s electrically heated and circulates through metal fins to slowly radiate heat.
Pros: Quiet, retains warmth even after switching off
Cons: Heats up more slowly, bulky in size
Benefits and Limitations
High Efficiency: Electric heaters convert almost all electricity into heat—ideal for personal or zoned heating
Localized Heating: Perfect for bedrooms, offices, or supplemental warmth
Limited Capacity: Most portable models max out at 1500 watts, suitable for areas up to 150 square feet
Running Cost: Depends on local electricity rates—on average, running a 1500W heater costs $0.12–$0.25 per hour
Electric Heater Safety Guidelines
To stay safe while using electric heaters, follow these essential practices:
Maintain Clearance: Keep at least 3 feet of space around the heater
Use Certified Devices: Look for heaters with tip-over protection and overheat shutoff
No Extension Cords: Always plug directly into a wall outlet
Supervised Use Only: Don’t leave heaters running unattended or while sleeping
Flat, Hard Surfaces Only: Avoid using heaters on rugs, beds, or unstable surfaces
Inspect Regularly: Check for frayed cords or other damage before each use

While fans rely on wind speed to create a cooling sensation, air coolers depend on another key element—air flow. Air flow (sometimes called air delivery) determines how much cooled air the unit can push into your room, and it has a direct impact on comfort, humidity control, and cooling coverage. This article explains what air flow is, why it is essential to an air cooler’s performance, and how to choose the right air flow level for your space. What Is Air Flow in an Air Cooler? Air flow refers to the volume of air an air cooler can move per minute. It is usually measured in: CFM (Cubic Feet per Minute) m³/h (Cubic Meters per Hour) Higher air flow means the air cooler can deliver more cooled air across a wider area. Unlike a fan—where the sensation comes from wind speed—an air cooler relies on air flow ... -
Many people wonder if simply circulating air can actually make a room cooler. While an air circulator doesn’t lower the room’s temperature the same way an air conditioner does, it does make your environment feel significantly cooler and more refreshing. Let’s explore how air circulation works, why it matters for comfort, and how using an air circulator fan can improve your room’s cooling efficiency—especially during hot summer months. The Science Behind Air Circulation and Cooling When air in a room becomes still, heat builds up around objects and people. Stagnant air traps warmth and humidity, making the space feel hotter than it really is. An air circulator fan solves this by moving air continuously around the room. This motion helps: Distribute cooler air evenly instead of letting it settle near vents or windows. Evapor...

An air circulator fan is one of the most versatile tools for improving indoor comfort. Unlike traditional fans that simply blow air in one direction, an air circulator is designed to move air throughout the entire room—creating a continuous, balanced flow. However, to get the best results, where you place it matters just as much as how you use it. This guide explains the science behind airflow, the best positions for your air circulator, and how to optimize performance for both cooling and heating seasons. How Air Circulation Works Air circulators work by creating a steady airflow loop within a room. Instead of targeting one person, they push air across walls and ceilings, helping to mix warm and cool air layers evenly. This process: Eliminates hot or cold spots. Improves overall ventilation. Makes rooms feel fresher and more comfortable year-round. The...
