Introduction
A warm garage is a valuable asset, providing a comfortable workspace and protecting vehicles and belongings from harsh winter weather. This comprehensive guide outlines the steps for a safe and successful DIY garage heater installation. We’ll cover two popular options: forced-air heaters and low-intensity infrared heaters, helping you choose the best fit for your needs.
Choosing the Right Heater
Before diving into installation, it’s crucial to select the right heater type. Two primary options exist for garage heating:
Forced-Air Heaters
These heaters function similarly to a traditional furnace, blowing warm air throughout the garage.
Pros:
- Lower initial cost compared to infrared heaters.
Cons:
- Can be noisy due to the blower fan.
- Heat loss is significant when the garage door is opened.
- Air movement stirs up dust, potentially affecting finishing projects.
Infrared Tube Heaters
These heaters radiate heat, warming objects directly rather than the air.
Pros:
- Quieter operation compared to forced-air heaters.
- Minimal air movement, reducing dust circulation.
- More uniform heat distribution.
- Lower operating costs due to efficient heating.
Cons:
- Higher initial cost compared to forced-air heaters.
- Precise placement is crucial to avoid overheating objects or individuals.
Factors Influencing Heater Choice
Consider these factors when deciding:
- Budget: Forced-air heaters offer a more budget-friendly initial investment.
- Air Quality: Infrared heaters are preferable for dust-sensitive tasks like woodworking.
- Heat Distribution: Infrared heaters provide more even warmth.
- Noise Level: Infrared heaters operate more quietly.
- Ceiling Height: Infrared heaters require a minimum ceiling height for safe installation.
Installation Process
Note: Before starting any installation, consult local building codes and ensure you have the necessary permits. Always disconnect power and gas supply before working with electrical or gas lines.
General Preparation:
Both heater types require:
- Insulation: Adequate insulation in walls and ceiling is essential for energy efficiency.
- Venting: Proper venting is mandatory for gas-powered heaters to expel exhaust gases safely.
- Electrical Connection: Both types require an electrical connection for operation. Consult a qualified electrician if needed.
Forced-Air Heater Installation:
- Placement: Typically installed in a corner, near existing gas and electrical connections. Consult manufacturer instructions for specific clearance requirements.
- Gas Line Connection: Use approved gas piping and connectors. Apply plumber’s tape to threaded connections to prevent leaks. Have a qualified professional connect the gas line if needed.
- Electrical Connection: Connect the heater to a dedicated circuit breaker according to manufacturer instructions.
- Venting: Install the vent pipe according to local codes and manufacturer specifications.
Infrared Tube Heater Installation:
- Placement: Install at least 7 feet above the floor, maintaining a minimum 3-4 foot clearance from objects below. Placement towards the garage door, angled downwards, is often recommended.
- Gas Line Connection: Similar to forced-air heaters, use approved materials and techniques. Consult a professional for gas line connections if necessary.
- Electrical Connection: Connect to a dedicated circuit as per manufacturer instructions.
- Suspension: Securely hang the heater using appropriate hardware, ensuring it’s level and stable.
BTU Requirements
The required BTU (British Thermal Unit) rating depends on garage size, climate, and desired temperature. As a general guideline:
- Forced-Air: 45,000 BTU for a two-car garage, 60,000 BTU for a three-car garage.
- Infrared: 30,000 BTU for a two-car garage, 50,000 BTU for a three-car garage.
Safety Considerations
- Professional Assistance: For gas line connections and complex electrical work, consult qualified professionals.
- Carbon Monoxide Detectors: Install carbon monoxide detectors in the garage to ensure safety.
- Clearance: Maintain proper clearances around the heater to prevent fire hazards.
Conclusion
Installing a garage heater is a significant home improvement project that can enhance comfort and usability. By carefully choosing the right heater type and following proper installation procedures, you can enjoy a warm and functional garage year-round. Remember to prioritize safety and consult professionals when needed.
