Wall Mounted Electric Heater For Garage

Keeping your garage warm during the colder months can significantly improve its usability. Whether you're a hobbyist, a mechanic, or simply need a place to store your vehicle and belongings, a comfortable temperature makes all the difference. Wall-mounted electric heaters offer a practical and efficient solution for heating garages. This guide will walk you through everything you need to know, helping you choose the right heater and ensuring safe and effective installation.

Understanding Wall-Mounted Electric Heaters

Wall-mounted electric heaters are self-contained units that attach directly to a wall. They convert electrical energy into heat, distributing it throughout the space. Unlike portable heaters, they save floor space and offer a more permanent heating solution. They come in various sizes and power levels, making them suitable for different garage sizes.

Types of Wall-Mounted Electric Heaters

Several types of wall-mounted electric heaters are available, each with its own advantages and disadvantages. Understanding these differences will help you select the best option for your needs.

Forced Air Heaters

Forced air heaters operate by drawing air in, heating it using an electric heating element, and then blowing the warm air back into the room with a fan. Think of it like a hairdryer, but on a larger scale. They are effective at quickly warming up a space and are generally more affordable than other types. However, they can be noisier due to the fan operation.

Infrared Heaters

Infrared heaters, also known as radiant heaters, emit infrared radiation that directly heats objects and people within their range. They don't heat the air itself, so they provide instant warmth and are very efficient. They're ideal for spot heating and are relatively quiet. However, their heating range is limited, and they may not be as effective in large, poorly insulated garages.

Convection Heaters

Convection heaters warm the air that surrounds them. As the air heats up, it rises, creating a natural convection current that circulates warm air throughout the room. They are quieter than forced air heaters, but they typically take longer to heat a space. They are a good option for maintaining a consistent temperature in a well-insulated garage.

Key Features to Consider

When choosing a wall-mounted electric heater for your garage, several features are worth considering:

Heating Capacity (BTUs or Watts): This indicates the amount of heat the heater can produce. Higher BTU/wattage means more heating power, suitable for larger spaces.
Thermostat: A built-in thermostat allows you to set and maintain a desired temperature. Look for adjustable thermostats for precise control.
Safety Features: Overheat protection is crucial. This feature automatically shuts off the heater if it gets too hot, preventing fires. Also, consider models with tip-over protection if there's a risk of the heater being accidentally bumped.
Voltage and Amperage: Match the heater's voltage and amperage requirements to your garage's electrical system. Most garage heaters require 240V, so ensure you have the appropriate electrical outlet.
Fan Speed Settings: Some forced air heaters offer multiple fan speed settings, allowing you to adjust the airflow and noise level.
Remote Control: A remote control can be convenient for adjusting the temperature or settings from a distance.
Timer: A timer allows you to set the heater to turn on and off at specific times, saving energy.
Durability: Look for heaters with durable construction and a robust housing, especially if your garage is a busy workspace.

Sizing Your Heater for Your Garage

Choosing the right size heater is crucial for optimal performance and energy efficiency. An undersized heater will struggle to heat the space adequately, while an oversized heater will cycle on and off frequently, wasting energy and potentially shortening its lifespan.

Calculating Heating Needs

A general rule of thumb is to use 10 watts of heating power per square foot of garage space. However, this is just a starting point. Several factors can influence your heating needs, including:

Garage Size: The larger the garage, the more heating power you'll need.
Insulation: A well-insulated garage will require less heating power than a poorly insulated one. Pay attention to the walls, ceiling, and doors.
Climate: Garages in colder climates will require more heating power.
Garage Usage: If you plan to use the garage frequently and want to maintain a consistently warm temperature, you'll need a more powerful heater.

To get a more accurate estimate, you can use an online heating calculator or consult with an HVAC professional. These tools take into account all the relevant factors to determine the appropriate heating capacity for your garage.

Example Calculation

Let's say you have a garage that is 20 feet long and 20 feet wide (400 square feet). Assuming average insulation and a moderate climate, you would need approximately 4,000 watts (400 square feet x 10 watts/square foot) of heating power. This translates to a 4kW heater. Always round up to the nearest available size.

Installation Considerations

Proper installation is essential for safe and efficient operation. It is highly recommended to hire a qualified electrician for the installation, especially if you need to run a new electrical circuit or install a dedicated outlet. Incorrect wiring can be dangerous and could void the heater's warranty.

Electrical Requirements

Most wall-mounted electric heaters require a 240V electrical outlet. This is a different type of outlet than the standard 120V outlets found in most homes. You'll likely need to have a new 240V circuit installed by an electrician. Ensure the circuit breaker is properly sized for the heater's amperage requirements. Never attempt to install a heater without the appropriate electrical infrastructure.

Mounting Location

Choose a mounting location that is clear of obstructions and provides adequate airflow. Avoid placing the heater near flammable materials or in areas where it could be easily damaged. The heater should be mounted securely to the wall, using appropriate hardware. Follow the manufacturer's instructions carefully.

Safety Precautions

Always follow these safety precautions when installing and using a wall-mounted electric heater:

Turn off the power at the circuit breaker before beginning any electrical work.
Use appropriate wiring and connectors.
Ensure the heater is properly grounded.
Do not cover the heater or block its airflow.
Keep flammable materials away from the heater.
Regularly inspect the heater for any signs of damage.
Never leave the heater unattended for extended periods.

Maintenance and Care

Proper maintenance will help extend the lifespan of your wall-mounted electric heater and ensure its safe and efficient operation. Regular cleaning and inspection are key.

Cleaning

Regularly clean the heater to remove dust and debris that can accumulate on the heating element and fan. Use a soft cloth or vacuum cleaner with a brush attachment to clean the exterior of the heater. Before cleaning, always disconnect the heater from the power source.

Inspection

Periodically inspect the heater for any signs of damage, such as frayed wires, loose connections, or cracks in the housing. If you notice any problems, disconnect the heater and contact a qualified electrician for repairs. Do not attempt to repair the heater yourself unless you are a qualified electrician.

Troubleshooting

Here are some common problems and potential solutions:

Heater not turning on: Check the circuit breaker, power cord, and thermostat setting.
Heater not producing enough heat: Check the thermostat setting, air filter (if applicable), and heating element.
Heater making unusual noises: Check the fan for obstructions or damage.
Heater shutting off frequently: Check for overheating and ensure the heater is not covered or blocked.

If you are unable to resolve the problem yourself, contact a qualified electrician or the heater manufacturer for assistance.
