Draper 3kW Oil Filled Radiator
Best OverallPros
- Near silent operation
- Even, radiant heat without drying air
- Safety tip-over switch and overheat protection
Cons
- Slow to heat up initially
- Heavier and less portable than fan heaters
This oil filled radiator from Draper is the ideal choice for anyone who spends long hours in a garage workshop. It uses diathermic oil to produce steady, silent heat that warms the room evenly without the blast of hot air or noise associated with fan heaters. Owner reviews consistently highlight how comfortable it feels, even after running for an entire day.
The 3 kW output is sufficient for most single-car garages and small workshops up to 25 square metres. The adjustable thermostat lets you set a target temperature, and the unit will cycle on and off to maintain it, saving energy. While it takes around 15-20 minutes to reach full temperature, the sustained warmth it provides is superior to any fan-based alternative for long sessions.
Draper 5kW Fan Heater
Best for Large SpacesPros
- Very high heat output for large garages
- Heats up a cold room in minutes
- Lightweight and easy to move
Cons
- Noisy fan operation
- Can dry out the air and stir up dust
When you need to warm a large, draughty garage quickly, the Draper 5kW Fan Heater is the most powerful option in this lineup. It forces air over a heating element and circulates it rapidly, making it ideal for spaces up to 40 square metres. Owner reviews note that it can take the edge off a freezing garage in under five minutes.
The trade-off is noise and air quality. The fan is loud enough to be intrusive during detailed work, and the constant airflow can blow dust around. It also lacks a built-in thermostat, so you have to monitor the temperature manually. This heater is best used as a rapid warm-up tool before switching to a quieter oil-filled model for ongoing work.
Draper 2kW Infrared Heater
Best BudgetPros
- Very affordable price point
- Instant heat on people and objects
- Compact and wall-mountable
Cons
- Does not heat the air, only objects in line of sight
- Not suitable for whole-garage heating
The Draper 2kW Infrared Heater is a budget-friendly solution for targeted warmth. Instead of heating the air, it emits infrared radiation that warms people and objects directly, much like the sun. This makes it very efficient if you are working at a bench and want to feel warm without heating the entire garage volume.
Owner feedback praises its low running cost and compact size, but notes that it is ineffective for general space heating. If you move out of the infrared beam, you feel cold again. It is a great secondary heater or a primary heater for very small, well-insulated workspaces where you stay in one spot.
Draper 2kW Convection Heater
Best for Medium WorkshopsPros
- Quieter than fan heaters
- Good for consistent background warmth
- Thermostat control for energy saving
Cons
- Slower to heat up than fan models
- Less powerful than oil filled options
The Draper 2kW Convection Heater sits between the oil filled and fan models. It works by drawing in cool air, heating it over an element, and letting it rise naturally. This creates a gentle, even warmth that is quieter than a fan but faster to respond than an oil radiator.
Owner reviews indicate it is a solid mid-range choice for medium workshops around 20 square metres. The adjustable thermostat helps maintain a set temperature without wasting electricity. It is not the best for very cold spaces, but for a moderately insulated garage, it offers a good balance of performance and cost.
Draper 3kW Fan Heater with Thermostat
Best for Fast Warm-UpPros
- Thermostat for automatic temperature control
- Compact and portable design
- Faster heat up than oil filled models
Cons
- Fan noise is noticeable
- Less comfortable for long-term use than oil filled
This 3 kW fan heater from Draper adds a useful thermostat to the fan heater formula, allowing it to maintain a set temperature automatically. It is a step up from the basic 5 kW model in terms of convenience, and the 3 kW output is still powerful enough for most single garages.
Owner reviews appreciate the thermostat for preventing overheating, but note the fan noise is similar to other fan heaters. It is a good choice for those who want the speed of a fan heater but with some energy-saving smarts. For long sessions, the oil filled radiator remains more comfortable.
What to check before buying a Draper garage heater
Garage heaters are rated by power output in kilowatts (kW). A general rule is that you need roughly 1 kW of heat for every 10 square metres of garage space, but this varies with insulation levels. An uninsulated garage may need double that. Check the heater's coverage rating against your garage size.
Consider the heat type. Oil filled radiators provide steady, silent heat but are slow to warm up. Fan heaters are fast and powerful but noisy. Infrared heaters are efficient for spot heating but do not warm the air. Choose based on whether you need background warmth or instant, directed heat.
Safety features are essential. Look for tip-over switches, overheat protection, and a thermostat that prevents the unit from running continuously. All Draper heaters in this guide include basic safety cut-offs, but models with thermostats offer better energy management.
Mistakes to avoid
Do not buy a heater with too low a power rating for an uninsulated garage. A 2 kW heater will struggle to heat a large, draughty space and will run constantly, wasting electricity. Conversely, a 5 kW fan heater in a small, insulated garage will cycle on and off too quickly and may feel uncomfortable.
Avoid assuming all heaters are quiet. Fan heaters are always noisy. If you listen to music or work on detailed tasks, an oil filled or convection heater is a better choice. Also, do not place heaters near flammable materials or leave them unattended for long periods, even with safety features.
FAQs
Are Draper garage heaters safe to leave on overnight?
No. Never leave any space heater unattended or running while you sleep. Always follow the manufacturer's safety instructions.
What size Draper heater do I need for a single garage?
A 2 kW to 3 kW heater is usually sufficient for a standard single garage of around 15-20 square metres, depending on insulation levels.
Which Draper heater is the quietest?
The Draper 3kW Oil Filled Radiator is the quietest, as it has no fan and produces heat silently through convection and radiation.
Do Draper heaters come with a warranty?
Yes, most Draper heaters come with a standard 1-year warranty. Check the specific product listing for exact terms.
Can I use a Draper fan heater in a dusty garage?
Yes, but the fan will blow dust around. It is better to use an oil filled or infrared heater in dusty environments to avoid circulating particles.
What is the difference between convection and oil filled heaters?
Convection heaters use a metal element to heat air directly, while oil filled heaters heat oil inside a sealed radiator. Oil filled heaters retain heat longer and provide more even warmth.
Are infrared heaters good for whole garage heating?
No. Infrared heaters only warm objects and people in their direct line of sight. They are not effective for heating the air in the entire garage.
How do I know if my garage has enough power for a 5 kW heater?
A 5 kW heater draws around 21 amps. Most standard home circuits are 15-20 amps. You may need a dedicated circuit or a lower power heater.
Do Draper heaters have thermostats?
Some models do. The Draper 3kW Oil Filled Radiator and the 3kW Fan Heater with Thermostat include adjustable thermostats for temperature control.
Which Draper heater is best for a small workshop?
The Draper 2kW Convection Heater is a good choice for a small, insulated workshop, offering quiet operation and a thermostat.
Our verdict
For most garage users, the Draper 3kW Oil Filled Radiator is the best overall choice, delivering quiet, comfortable, and efficient heat. If you need the fastest warm-up for a large, cold space, the Draper 5kW Fan Heater is the most powerful option. For budget-conscious users working in a fixed spot, the Draper 2kW Infrared Heater offers the best value.
