Looking for a serious heat boost for your outdoor space? These 13kW patio heaters are designed to rapidly warm larger areas, perfect for extended entertaining or creating a truly cosy garden haven. Delivering substantial power, these heaters utilise infrared technology to directly warm people and objects, providing instant warmth without the slow build-up of traditional gas or electric heaters. Ideal for patios, decking, and balconies where maximum heat output is required, consider the size of your space when selecting – 13kW provides significant coverage.
These powerful heaters are constructed with durable materials to withstand outdoor conditions, although it’s important to check manufacturer specifications for weather protection details. Remember that due to their high power output, these units require adequate spacing from flammable materials and should be used responsibly according to the manufacturer's instructions. Amazon UK currently lists a range of 13kW patio heaters from various brands.
When choosing a 13kW heater, consider the distance you need to cover – larger areas will naturally require more power. Always ensure a stable, level surface for placement and consult with an electrician if unsure about electrical connections or safety regulations. Amazon’s selection offers diverse design options, so compare features like adjustable height settings and included accessories.
FAQ
What exactly is infrared heating?
Infrared heaters emit radiant heat directly at objects and people, rather than warming the air around them. This creates a very immediate and noticeable warmth, unlike convection heaters which rely on circulating air.
How far will 13kW heat reach?
With 13kW power, you’ll typically achieve effective heating up to approximately 15-20 metres in an open space, although this varies depending on factors like wind and surrounding surfaces.
Are these heaters weatherproof?
Check the specific product details on Amazon for weather protection ratings. Many models have IP44 or higher splashproof ratings, but full weatherproofing may require a cover when not in use.
What safety precautions should I take?
Always position your heater at least 1 metre away from flammable materials and keep it out of reach of children and pets. Regularly inspect the power cable for damage and never operate with a damaged cord.
Can I adjust the heat output?
Many 13kW patio heaters feature adjustable heat settings, allowing you to tailor the warmth to your needs and conserve energy when full power isn't required.
How long will it take to heat a space?
Initial heating time depends on the area’s size and insulation. Expect approximately 15-30 minutes for a moderate-sized patio, but larger areas might need longer to reach desired warmth.
What electrical connection do these heaters require?
Most 13kW models require a dedicated 13A mains supply. Always consult with a qualified electrician before making any electrical connections to ensure compliance with regulations.
Are there any specific surface requirements?
For optimal heat transfer, place the heater on a non-metallic, level surface. Avoid placing it directly on paving stones or wood which can reflect heat away from people and objects.
What is the typical lifespan of a 13kW patio heater?
With proper care and maintenance (following manufacturer guidelines), you can generally expect a lifespan of around 5-7 years for these heaters, though usage patterns will influence longevity.
How do I clean a 13kW patio heater?
Always disconnect the heater from the power source before cleaning. Use a damp cloth to wipe down the surface and avoid using harsh chemicals or abrasive cleaners that could damage the finish.
