The Ultimate UK Guide to Choosing the Best Outdoor Heaters

Updated October 2026 · Meteor Electrical Guides

There is nothing quite like relaxing outdoors with family, friends, or customers, yet unpredictable UK weather frequently cuts those gatherings short. As the evening chill sets in, beautiful garden patios, pergolas, and hospitality terraces often sit empty and unused.

Modern heating technology has completely changed that dynamic. High-performance outdoor heaters turn draughty, chilly exterior spaces into warm, welcoming retreats that you can comfortably enjoy 365 days a year. Whether you manage a busy restaurant terrace, oversee commercial premises, or simply want to extend barbecue season in your back garden, selecting the right outdoor heating system is essential for lasting comfort and sensible running costs.

Why Should You Invest in an Outdoor Heater for Your Property?

Investing in an outdoor heater does far more than just take the edge off a chilly evening. It transforms an underutilised patio or courtyard into a fully functional, high-value living space.

For homeowners, energy efficient outdoor heaters extend the summer season well into late autumn and early spring. You can host garden dinners, enjoy a morning coffee on the deck, and entertain without shivering or crowding everyone indoors.

For commercial enterprises such as pubs, cafés, and restaurants, commercial outdoor heating is an operational necessity. Outdoor seating directly dictates customer capacity. Providing consistent, comfortable warmth encourages diners to stay longer, order additional rounds, and visit throughout the off-season, which provides an immediate boost to hospitality revenue.

What Are the Different Types of Outdoor Heaters Compared?

Choosing the right heater begins with understanding how different heating technologies perform in outdoor environments.

Electric Infrared Heaters

Electric infrared heaters emit radiant energy that travels through the air until it contacts a solid surface, such as furniture or people. Because they do not rely on heating the surrounding air, their warmth is less affected by sudden gusts of wind. They run cleanly and silently, require no fuel refills, and start warming the area almost instantly.

Gas Patio Heaters

Gas heaters run on bottled propane or piped natural gas. While they generate high-output warmth, they rely primarily on convection, heating the air around the flame. In breezy or open conditions, that heated air quickly rises and disperses. Gas units also require cylinder replacements where applicable, suitable ventilation clearances, and ongoing safety maintenance.

Wall-Mounted vs Freestanding Configurations

• Wall-mounted patio heaters: Ideal for fixed dining zones, narrow balconies, and commercial seating. Mounting at a downward angle of 30 to 45 degrees can keep floor space unobstructed and direct heat towards occupants, subject to the manufacturer's instructions.
• Freestanding heaters: Offer flexible positioning and may provide broad heat coverage. Models with stable anti-tip bases, wheels, or carry handles can make it easier to rearrange an outdoor layout.

How Do You Choose and Position an Outdoor Heater for Maximum Warmth?

Proper heater placement determines whether your exterior area stays comfortably warm or suffers from cold patches. Use these steps to plan your power needs and installation safely:

1. Calculate the area and wattage: Allow roughly 150 to 250 watts of heating power for every square metre of sheltered outdoor space. For exposed, wind-prone gardens, the source guide suggests 250 to 300 watts per square metre. Actual requirements depend on the heater, layout and conditions.
2. Select the mounting height: The source guide suggests mounting wall units between 2.1 and 2.7 metres above ground. Always follow the exact model's installation instructions and required clearances.
3. Angle the reflector: Where the manufacturer permits, angle wall-mounted heaters downwards towards the main seating zone to focus heat where guests sit.
4. Maintain safe clearances: Keep the heater away from side walls, fabrics, plants, parasols and other combustible materials according to the manufacturer's stated distances. Do not rely on a generic clearance where the product specifies a different one.
5. Install suitable controls: Timers or presence sensors may help reduce unnecessary energy use, where compatible with the heater and installation.

Frequently Asked Questions (FAQs) About Outdoor Heaters UK

1. What IP rating is required for an outdoor patio heater?

Choose an Ingress Protection rating suitable for the heater's location and exposure. The source guide recommends looking for IP55 or higher, but always check the product instructions and installation conditions rather than relying on the rating alone.

2. Are electric infrared outdoor heaters expensive to run?

Running costs depend on the heater's wattage, how long it operates and the electricity tariff. A 2000W heater uses 2kWh of electricity per hour at full power, so multiply 2 by your unit rate to estimate the hourly cost.

3. Can outdoor electric heaters be used under covered gazebos and awnings?

Some electric infrared models are suitable for covered structures because they produce no combustion fumes. Always observe the manufacturer's required clearance distances from fabrics, ceilings and other materials, and confirm the product is approved for that setting.

4. How much area does a 2000W outdoor heater cover?

The source guide estimates roughly 10 to 15 square metres in a sheltered or semi-enclosed patio and around 8 to 10 square metres in exposed, windy conditions. Actual coverage varies with the model, mounting position and weather.

5. Do infrared outdoor heaters produce an annoying red glare?

Some infrared heaters use gold halogen, quartz or other low-glare elements that emit a visible glow. Zero-glare models, such as the ATC Hot Top described in this guide, produce no visible light.

6. Is professional installation required for electric outdoor heaters?

Portable plug-in models may be suitable for connection to an appropriate outdoor RCD-protected socket. Fixed or hardwired units, particularly higher-powered models, should be installed by a qualified electrician in accordance with applicable wiring standards and the manufacturer's instructions.

7. Can electric patio heaters be left outside during the winter?

Only leave a heater exposed outdoors if its rating and instructions allow it. A suitable protective cover when the unit is not in use may help extend its life, but do not cover a heater while it is hot or operating.

8. What is the main difference between short-wave and long-wave infrared?

Short-wave infrared heaters often emit some visible amber light and can suit exposed areas where targeted radiant heat is needed. Long-wave infrared models emit little or no visible light and may suit sheltered spaces. Choose according to the product specification and intended environment.
