If you’ve ever been to the Alps in winter, you will have experienced the sudden warmth on your body when the sun peeks through the clouds. One minute it’s freezing cold, the next you’re unzipping your skiing clothes because it almost feels like a summer’s day on the Costa del Sol. That, in a nutshell, best describes how infrared heating works. If you’re after an infrared heater that retains and emits a certain amount of heat once it’s been turned off, try the Klarstein HeatPal for size. The HeatPal works just like an oil-filled model, only it’s much more energy-efficient – and, in many ways, more effective. This is because it has a very heavy slab of unpolished Mongolian marble sitting behind the grille, which is heated by the element behind it to produce an amazing amount of heat that’s pushed outward and upward. Adding the warmth of an outdoor heater to your outdoor dining set or installing a freestanding or wall-hung patio heater will allow you and friends or family to linger outside for longer – despite any chill in the air or the unpredictability of British weather. Twin tube carbon heaters can be easily retrofitted into existing infrared systems. They replace the existing heaters, improve the system and decrease the running costs. carbon-twin In the medium wave range, Heraeus offers tailor-made twin tube heaters or carbon round tube heaters of especially high efficiency. The synergistic combination of these proven technologies allows great advantages for your process.

However, it does come up short in some regards. Whichever of the three available sizes you opt for (73cm, 84cm, or 98cm tall) they're a significant investment. And for their price, it's a shame you only get one heat setting – a rather uneconomical 2000W – with no option to tone the heat down to save energy and expense. An oscillating patio heater, or one that dishes out multi-directional heat, can be a good bet if you have multiple people sharing one heat source.As a result of this technology, Halogen Heaters are the safest type of heater, posing the fewest health concerns compared to oil/fan/ceramic heaters. How much energy do Halogen Heaters use? In terms of weight, electric halogen heaters typically sit somewhere in between convection and fan heaters. Quartz and carbon infrared heaters produce a bit of soft red-glowing light. This is an indication that they produce some short-wave infrared radiation. Although they are safe to use, I recommend not staring into the light for too long. Additionally, make sure you read the safety instructions carefully. Some instructions mention a required distance from other (flammable) objects) Heraeus Carbon IR heaters have a unique filament design that combines the versatile medium-wave spectral emission with very short reaction times of just seconds. They are made with high-quality quartz tubes and gold reflectors for high efficiency. The unique Heraeus "Figure 8" Twin Tube design gives Heraeus carbon lamps higher power densities and good mechanical stability. Round tube designs are also available.

It offered good heat distribution in our tests, and its generous size and tall design made it a great option for keeping standing guests warm at an outdoor gathering. Plus, it looks good, with its high borosilicate glass tube and visible gas flame creating a real focal point as dusk draws in, and needing less active maintenance than a wood-burning fire pit. If you opt for a freestanding or wall hung patio heater then a remote control can also come in useful so you don't have to get up and down from your seat to adjust the heat.

The three bar quartz halogen heater is an excellent choice for keeping your home warm throughout the chilly winter months. This one, like most freestanding halogen heaters, includes an oscillation feature and three heat settings. Investing in one of the best patio heaters on the market can be a great way to maximise time spent al fresco and extend your enjoyment of your outdoor space. Halogen heaters deliver heat almost instantaneously, and the radiant heat they emit effectively heats a small area, reducing the amount of energy consumed by the heaters. If we find any major problems with how well the products function, they don’t make it onto our list.
