Infrared patio heater

Infrared creates a warm, evenly heated atmosphere in seconds. The rays bounce around their environment, heating objects they come into contact with, compared to outdated patio heaters which lose the majority of their heat as soon as it’s generated. No more bulky heaters. No more gas bottles.

Low energy.
Low cost.

Looking to save money on your energy billsΔ and invest in the latest heating technology? Infrared heaters are the way. They use a lower wattage than traditional patio heaters, and are much more efficient as less heat is lost. Silently and discreetly, they convert almost 100% of the electricity they use into usable heat.

How effective are electric outdoor heaters?

Each Gtech electric garden heater is equipped with the latest infrared technology. Infrared has a double benefit of being both eco-friendly (hardly any energy goes to waste) and high performance. The result? You stay warm outdoors – without the typical high costs.

If you’re not sure how infrared technology outdoor heaters differ from your standard garden patio heater, let us talk science. Infrared technology emits what is known as ‘radiant heat’ and gas heaters produce ‘convective heat’. While the latter produces large amounts of warmth, only the air around the patio heater heats up – and this disappears rapidly in outdoor spaces.

Our Heatwave outdoor patio heaters, on the other hand, evenly target areas within a six-metre radius, meaning you (and not the air around your heater) get the full balmy benefits.

Can you leave electric patio heaters outside?

Yes! That’s the beauty of our Gtech outside patio heaters - they can stay outside, come rain or shine.

If you’re looking for extra reassurance, we always advise our customers assess the electrical safety of their products. For instance, our HeatWave electric outdoor heater has received an IP65 weatherproof rating. This is the industry standard for any outdoor weather-resistant electrical product.

For future reference, an IP rating (Ingress Protection rating) classifies the different levels of sealing effectiveness. The IP65 rating ensures protection against not just torrential downpours, but also stronger manmade events, like water jets.

Electric patio heaters vs gas patio heaters

Gas patio heaters seem cheaper at first (in terms of total power output vs initial price), but their poor energy efficiency makes them more expensive than electric patio heaters in the long run. In fact, gas garden heaters consume about 1.25kg of gas per hour to maintain their substantial energy output.

What’s more, Gtech wall mounted patio heaters slot seamlessly and discreetly into seating areas. Unlike cumbersome gas patio heaters, our low-maintenance small patio heater is portable and can be easily attached to any solid outdoor surface. If you wish to reposition your garden patio heater, simply detach and reattach as you please – easy!

Do outdoor patio heaters use a lot of electricity?

The Gtech HeatWave patio heater's running cost is approximately 60p/hour using an average UK standard electricity tariff of 28p/kWh, but may be higher depending on your electricity supplier and tariff.

Can you use an outdoor patio heater in the winter?

Absolutely! While you're most likely to want to use during the summer, when the evening temperate drops, they are great during colder seasons too. The Gtech electric heater warms up in just 1 second, and reaches up to 6m.

Are infrared patio heaters safe?

Safety is always a top priority for us, and rest assured our infrared patio heater is 100% safe. The main unit may get warm when in use though, so just be careful not to touch with bare skin.

Δ HeatWave running cost is approximately 60p/hour using an average UK standard electricity tariff of 28p/kWh, but may be higher depending on the customer's electricity supplier and tariff.
