Sealey 2kW Oil Filled Radiator
Best OverallPros
- Very quiet operation
- Even heat distribution
- Built-in thermostat
Cons
- Slower to heat up
- Heavier than fan heaters
The Sealey 2kW Oil Filled Radiator is a reliable choice for consistent warmth. Owner reviews highlight its quiet performance and ability to maintain a steady temperature without noise. It features three heat settings and an adjustable thermostat for control.
Safety is strong with tip-over and overheat protection. The unit is portable with castors but takes time to reach full heat. It is ideal for those who need a heater running for hours in a garage workshop.
Clarke 1.5kW Fan Heater
Best BudgetPros
- Very affordable
- Heats up instantly
- Compact and lightweight
Cons
- Noisy fan
- Not for large garages
The Clarke 1.5kW Fan Heater is a budget-friendly option that delivers immediate heat. Owner reviews note it is perfect for small to medium garages where quick warmth is needed. It has a simple on/off switch and a thermal cut-out for safety.
It is not suitable for large spaces due to its lower power output. The fan noise is noticeable, which may be distracting in a quiet workspace. For the price, it is a solid entry-level heater.
Draper 3kW Infrared Heater
Best for Large SpacesPros
- Heats objects directly
- Weather resistant
- Suitable for large garages
Cons
- Higher power consumption
- Requires hardwiring
The Draper 3kW Infrared Heater is designed for larger garages or workshops. Infrared technology heats people and objects directly rather than the air, making it efficient in draughty spaces. Owner reviews praise its robust build and IP54 rating for dust and water resistance.
Installation is more complex as it needs to be hardwired by an electrician. It is not portable like other options. For those with a large, well-insulated garage, this is a powerful solution.
Sealey 2kW Convector Heater
Best for Quick WarmthPros
- Quick heat up
- Quieter than fan heaters
- Portable and slim
Cons
- Can be less efficient in large spaces
- Surface gets hot
The Sealey 2kW Convector Heater offers a balance between speed and quietness. It uses natural convection to circulate warm air, heating up faster than an oil radiator but quieter than a fan heater. Owner reviews appreciate its slim design for easy storage.
It is best for medium-sized garages. The exterior can become hot to touch, so it should be placed away from flammable materials. It includes a tip-over switch for safety.
Stanley 2kW Halogen Heater
Best for PortabilityPros
- Lightweight and easy to move
- Instant heat
- Low cost
Cons
- Bright light can be distracting
- Not for very cold climates
The Stanley 2kW Halogen Heater is a portable and affordable option. It provides instant radiant heat and is very lightweight, making it easy to move around the garage. Owner reviews note it is good for spot heating while working.
The halogen bulbs produce a bright orange light, which some users find distracting. It is less effective in very cold or large garages. It is a decent choice for occasional use or small spaces.
What to check before buying a garage heater
Consider the size of your garage. A small single garage may only need a 1.5kW fan heater, while a larger double garage may require a 3kW infrared unit. Check the insulation level of your garage as well.
Look for safety features like tip-over switches and overheat protection. These are essential for unattended operation. Also consider noise levels if you plan to work in the garage for extended periods.
Mistakes to avoid
Do not buy a heater that is too powerful for your space, as it may cause frequent cycling on and off. Avoid placing heaters near flammable materials or using extension leads that are not rated for the power draw.
Do not ignore the type of heater. Fan heaters are noisy but fast, oil radiators are quiet but slow, and infrared heaters are best for targeted warmth. Choose based on your primary use case.
FAQs
What size garage heater do I need?
A 1.5kW heater is suitable for a small single garage up to 15 square metres. A 2kW to 3kW heater is better for larger or poorly insulated garages.
Are oil filled heaters safe for garages?
Yes, oil filled heaters are safe as they have no exposed heating elements and include tip-over and overheat protection. They are ideal for long, unattended use.
Can I use a fan heater in a garage?
Yes, fan heaters are safe for garages as long as they have overheat protection and are kept away from dust and flammable materials. They are best for short-term heating.
What is the most energy efficient garage heater?
Infrared heaters are often the most efficient for garages as they heat objects directly, reducing heat loss. Oil filled radiators are also efficient for maintaining a steady temperature.
Do I need a hardwired heater for my garage?
Only if you choose a high-power unit like a 3kW infrared heater. Most 2kW and below models can be plugged into a standard 13 amp socket.
How long does an oil filled radiator take to heat up?
An oil filled radiator typically takes 15 to 30 minutes to reach full operating temperature. It then provides consistent, even heat.
Can I leave a garage heater on overnight?
Only if the heater has a thermostat and safety cut-off features. Oil filled radiators are the safest option for overnight use.
What is the difference between convector and fan heaters?
Convector heaters use natural air circulation and are quieter, while fan heaters use a fan to blow air over a heating element and are faster but noisier.
Are halogen heaters good for garages?
Halogen heaters are good for spot heating and portability but are less effective for whole-garage heating. They also produce bright light.
Where can I buy a Halfords garage heater?
Halfords stocks a range of garage heaters in-store and online. Many models are also available on Amazon with competitive pricing.
