Split Air Conditioners UK Product Guide
Before selecting any of these products, you need to understand that there are particular features you should look out for. These ensure that you pick an ideal model for your environment, as the right combination of features determines how well the appliance performs in delivering quality service. It also helps to avoid issues related to a wrong purchase, returning hassles and general disgruntlement with the product.
These appliances come in various sizes, and your choice depends on certain factors. The wall space, room space, installation speed, and performance concerning the room size are essential things to analyze. You should consider how big the appliance you pick is, and if the room you plan on mounting it in has enough space to put it.
You also want to consider wall space, as you do not plan on having just the appliance taking over the entire wall. If the size is too big, it might make the wall look tacky, as visitors would find a hard time ignoring the gigantic-looking contraption you hung on your wall.
Larger sized products also take a longer time to install. Plus, you might waste a considerable amount of time mounting something that is eventually too bulky for your wall space. And since most powerful models are hefty in size, you might just find out that your selected appliance is nothing more than overkill for the space you use it in.
BTU stands for ‘British Thermal Unit’, and is the general parameter used to measure the cooling and heating capacity of an appliance. Different room sizes work best with individual BTU specifications, so you must learn how to identify the ideal capacity for your room space. Smaller rooms work best with appliances of about 8000BTU, and medium rooms conveniently accommodate those of 1000BTU or slightly more. And for larger room spaces, a machine operating at 15000BTU and above is most ideal.
The BTU measurement is a feature you cannot afford to ignore, and for a justifiable reason. Installing an appliance of lower BTU in a larger room means the effects of the device will be almost unnoticeable. And using those with more extensive BTU measurements in smaller rooms mean the cooling will be excess, and the appliance will have no chance for proper dehumidifying.
To understand how to compare the specifications thoroughly, smaller rooms are those measuring around 18 square meters, medium rooms start at 24 square meters, and larger room sizes range from 36 square meters and above. You also need to consider if the room you plan to use the appliance in has other electrical equipment. Places like the kitchen and garage door well with devices that offer up to 4000BTU. These models ensure the room gets optimum cooling, and eliminate the possibility of condensation on equipment due to less dehumidifying.
The EER, or Energy Efficiency Ratio, is an indication of how well the appliance manages and utilizes energy. This is essential, as you do not wish to rake in humongous energy bills because you want your room to be cooled continuously. Therefore, ensure to look out for appliances that offer a high EER rating. The higher the number, the more energy-efficient the unit automatically is.
Some split air conditioners also double as heaters and prove quite handy in days of colder weather. Since this is usually the general climate condition of the British environment, I highly recommend you go for an appliance that comes with this feature. That way, you can also enjoy sound healing effects in the cold season. And you know you can switch to cooling in times of unusual hotness.
You must also look out for other extra features that come with these appliances, as these enhance the versatility, usability and flexibility of the unit. Among these handy features are a timer, dehumidifier, fan speed adjustment features, as well as sleep or night mode.
Some models also come with smartphone control features, giving you more flexibility in operation. And a great majority of these appliances come with a standard remote control, allowing you to toggle between the various performance mode options in the unit.
Does brand matter when buying a split air conditioner?
Yes, and no. While certain brands like Fujitsu, Sharp, Panasonic and Hisense are generally known for top-quality products, some unpopular brands do offer a great advantage, regardless of their obscure identities. It may be wise to go for products that come from popular brands, as these companies dwell heavily on maintaining an untainted reputation.
However, appliances from popular brands tend to be on the pricey side and most times, hurt your pocket more than you may have planned for. The best advice would be to look out for products that offer essential features and high performance. Combine these with a very lengthy warranty, and you are sure to get great value for your money.
How do you size a split air conditioner?
To generally analyze the amount of air conditioning your living environment requires, the first step is to determine the size of your living quarters. Next is to combine the total dimension of the rooms, and the result would arrive in square meters. Then, you can use this measurement to decide what appliance will work best for your surroundings.
Can a split air conditioner be used for two rooms?
Yes, it can. You can conveniently generate enough cooling or heating for multiple rooms in your environment with both the multi and mini-split air conditioners. However, while the former allows you to set up different temperatures for each room, the latter only offers a general temperature for both.
Split air conditioners are an ideal companion for your home in warm weather. They offer great comfort by creating a calm surrounding. And they also double as heaters in the warm weather, ensuring your environment maintains a constantly tolerable temperature all year round. Such quality services make them a valuable addition to every home, office, workshop and living space.
In this review, I have featured the best appliances you can spend your money on. I have highlighted their features, as well as how to compare the various products. I have also included a product guide that explains the parameters to observe before making a final choice. I believe with this information, and you will find selecting the best product for your need to be an easy ordeal.
However, I understand if you still find it hard to decide what to pick. This is very expected, as every product listed here offers features that are too eye-catching to ignore. Based on my experience, I can narrow down the list to what I consider to be the best options for you to select from.
For the best appliance, I recommend Klarstein Windwaker Eco-Split, because it is a well-rounded unit. If you can afford to spare some extra money, Electriq Multi-Split is your best choice. But if your budget seems to restrict your spending, do not fear. Ambista Electric ALPHA is my top choice for a quality appliance unit; at a price, I consider to be a giveaway.
