However they are highly controversial as they mainly run on fossil fuels and, as their heat is largely dissipated, they are an extravagant use of these carbon-rich fuels.
While a patio heater warms you, it is also warming up the air and area around you — ultimately wasting energy. A typical gas-powered patio heater warming your table during a night out for just a couple of hours, might use up a huge MJ and emit 3 kg CO2. An equivalent, more efficient electric system would only use one-fifth of that energy, would be cheaper to run, and during the same evening would produce less than a kg of carbon dioxide.
There are greener alternatives, such as heaters that run on biogas or bioethanol from waste which burn cleanly and do not rely on fossil fuels, but this is still a very inefficient use of energy. This is more efficient in an outdoor setting and the effect is instant as soon as the heater comes on.
So far so good. The problem is that infrared heaters only heat whatever is in the path of radiation, like a hot torch. Anything not in the beam, or in a shadow, stays cold. This means that your arms, face and body may feel comfortable but your legs and feet under the table could still feel chilly. Gas and solid fuel heaters often look appealing at first glance but few people realise just how much effort they are to prepare and maintain. The electric outdoor heaters people are most familiar with are quartz heaters, also known as halogen heaters or low-glare heaters.
These patio heaters emit shortwave infrared — the strongest form of infrared — which is perfect for outdoor heating, particularly in areas that are quite chilly and prone to more air movement. As their vigorous heat is designed to offset cooler temperatures, their warmth can eventually start to feel overwhelming over longer periods.
We highly recommend purchasing products that have staged levels of output, such as our Ecostrad Sunglo , so you can switch to a lower heat setting on warmer days and save energy. Sophisticated, efficient and stylish, infrared heating is a modern solution that perfectly matches a range of spaces, which is why it continues to increase in popularity as a primary heating system. A resistor can be described as a material that inhibits the flow of electric current. This electric current that begins to move through is converted into heat energy by the resistor.
This hot air that is produced is then moved throughout the space to provide heat. All convection heaters work in basically the same way with only minor differences. Patio heaters that function using this process are not as energy efficient as patio heaters that rely on radiant heat. A patio heater is a device that is used to emit heat in a small patio area.
There are two basic design options to choose from including a domed shaped variety or one that is mounted directly to a wall. This means that all patio heaters are powered by electrical heating or a process known as propane combustion gas heating.
When it comes to outdoor heaters that are used in patio areas, domed shaped options are the most commonly used. This involves a dome shaped metal top that is attached to a long pole. Propane powered patio heaters are the most popular, but they are available in other types. Many patio heaters are even equipped with safety features including a automatic shutdown that is designed to occur when flaring or burning is at risk of taking place within the heater. A patio heater begins working as soon as it is powered on.
Propane is probably the most popular type of patio heater out here. However, you do have to replace the propane tank when it runs out. Natural gas is ideal for those homes with an existing natural gas line on their patio. Electric patio heaters have always been on the lower side as far as BTUs. However, they are getting close thanks to advances in technology. As you can probably guess, most electric patio heaters need to be plugged into an outlet to work.
Electric heaters come in many styles, and they can be mounted to a wall or ceiling to keep them out of the way. You can also get infrared heaters for your patio.
These are powered by electricity and typically wall-mounted. They tend to heat up faster and work better than traditional electric heaters due to their infrared technology which heats objects through radiant heat instead of simply heating the air like other similar heaters. However, if you have limited space you may consider a wall-mounted heater or a miniature stand-up version that you can safely place on a table or a stand.
Any type of patio heater comes with the risk of injury or fire due to improper use. Like a hot stovetop burner, patio heaters can burn you if you touch them in the wrong place. However, they are generally considered very safe. Most of the gas versions have a safety switch inside that shuts the system down if the unit is tipped over.
