This heater is freestanding and portable, so you can move it around your outdoor space. It runs on a standard propane tank, which is not included. It is a reliable choice for those who prefer gas heating and want a classic, tall heater design.
Haro 2000W Carbon Fibre Heater
Best Instant HeatPros
- Instant heat with no warm-up
- Carbon fibre elements last longer
- Quiet operation
Cons

The Haro 2000W Carbon Fibre Heater uses advanced carbon fibre elements to provide instant, focused heat. It is ideal for smaller patios or balconies where you need warmth immediately. Owners appreciate the lack of noise and the durable elements that outlast traditional quartz tubes.
This model is wall-mountable and has a slim profile, saving floor space. It lacks a remote, so you must use the built-in switch. For quick, targeted heating in a compact area, this is a very effective and affordable option.
Garden Sun 1.5kW Patio Heater
Best CompactPros
- Very portable and lightweight
- Simple plug-and-use
- Good for small spaces
Cons
- Lower heat output
- Limited coverage area

This heater plugs directly into a standard outlet, so no installation is needed. Its smaller size means it is less powerful than other models, but it is ideal for targeted warmth. It is a practical, low-cost solution for renters or those with limited outdoor space.
Sunred 2000W Infrared Heater
Best Energy EfficiencyPros
- Large coverage area
- Energy-efficient infrared technology
- Weather-resistant housing
Cons
- Heats objects, not air
- Installation required
The Sunred 2000W Infrared Heater uses infrared technology to heat people and objects directly, rather than the air. This makes it very efficient in windy conditions. It covers up to 12 square metres, making it one of the most powerful models in this price range. Owners value its weather-resistant build and consistent performance.
This heater is designed for permanent wall or ceiling mounting. It is less effective in very large, open spaces because it only heats what is in its direct path. For covered patios or gazebos, it offers excellent energy savings and reliable warmth.
What to check before buying a patio heater under £300
Consider the type of heater. Electric models are cheaper to run and easier to install, while gas models provide higher heat output for larger areas. Check the heat output, measured in watts (W) for electric or BTU for gas. A 2000W electric heater is suitable for most standard patios up to 10 square metres.
Look at the coverage area and mounting options. Wall-mounted heaters save floor space but require installation. Freestanding models offer portability but take up room. Also, check for features like remote controls, heat settings, and weather resistance ratings.
Mistakes to avoid when buying a patio heater
Do not ignore the coverage area. Buying a heater that is too weak for your space will leave you cold. Measure your patio and match it to the heater's specifications. Avoid choosing a gas heater if you have no easy access to propane refills, as running costs can add up.
Do not overlook safety features. Look for tip-over protection on freestanding models and overheat protection on electric units. Also, avoid installing a heater too close to flammable materials like umbrellas or wooden pergolas. Always follow the manufacturer's clearance guidelines.
FAQs
What is the best type of patio heater under £300?
Electric heaters are generally best for smaller, sheltered patios due to lower running costs and easy installation. Gas heaters are better for larger, open areas where you need more heat.
How much does it cost to run a 2000W patio heater?
Running a 2000W electric heater for one hour costs roughly 50p to 70p, depending on your electricity rate. Gas heaters can be more expensive to run, especially if using bottled propane.
Can I use a patio heater in the rain?
Most electric patio heaters are weather-resistant but not fully waterproof. They should be used under a covered area. Gas heaters can be used in light rain but should be protected from heavy downpours.
How do I install a wall-mounted patio heater?
Wall-mounted heaters require a sturdy wall bracket and a nearby power outlet. Some models need hardwiring by a qualified electrician. Always follow the manufacturer's installation instructions.
What is the difference between infrared and quartz heaters?
Infrared heaters warm objects and people directly, making them more efficient in windy conditions. Quartz heaters warm the air first, which can be less effective outdoors.
How long do patio heaters last?
Electric patio heaters can last 10 years or more with proper care. Gas heaters have a shorter lifespan, typically 5 to 8 years, due to wear on the burner and gas components.
Are gas patio heaters safe to use?
Yes, when used correctly. Always place them on a stable, level surface and keep them away from flammable items. Ensure proper ventilation and never use them indoors.
What size patio heater do I need for a 20 square metre patio?
For a 20 square metre patio, you will need a heater with around 3000W to 4000W of power. A single 2000W heater may not be enough, so consider two units or a high-output gas model.
Can I leave my patio heater on overnight?
It is not recommended to leave any patio heater unattended or on overnight. Always turn it off when you go inside or go to sleep to prevent fire hazards.
Do patio heaters need a special electrical outlet?
Most 2000W electric heaters can plug into a standard 13-amp household outlet. Higher wattage models may require a dedicated circuit. Check the plug type and amperage before buying.
Our verdict
For the best overall patio heater under £300, choose the Bromic Tungsten Smart-Heat Electric for its powerful 2000W output and premium design. If you need a budget-friendly gas option for larger spaces, the Fire Sense Commercial Patio Heater is a reliable and effective choice.
