Evaporative Cooler

Evaporative cooler systems are a popular alternative to air conditioning in the UK. The cooling is achieved by a different process to air conditioning, and the cooling power is not as strong. However, a hot air outlet is not required and the cooling power is often suitable for most applications in homes and commercial buildings.

Below, we will explore the types and costs of evaporative coolers, and you can also compare prices from local installers.

How much does an evaporative cooler cost?

There are a many factors that can influence the cost of an evaporative cooler installation. The main factors include:

  • Size – The building or room size you need to cool will decide the cooling power required. Larger rooms will need a larger and more powerful unit, which will increase costs. However, smaller areas will need a cheaper and less powerful unit, or even a portable evaporative cooler.
  • Location – Like most home improvements, the cost of installing an evaporative cooler will differ throughout the UK. In most cases, prices for installation will be higher in London and the South of England compared with further North and Scotland.
  • System Specifications – The features and specification of your chosen system will influence the price. Basic models, with limited features will cost less than deluxe models, with more advanced features.

Portable Evaporative Air Coolers

As well as installed systems, you may want to consider a portable evaporative cooler. These systems are generally best suited to smaller rooms, due to the limited cooling power. A portable evaporative cooler costs from £30 to more than £400. When it comes to cooling, you will receive far better results from the higher end models in the £200 – £400 price range.

Evaporative Cooler vs Air Conditioners

Whilst they have the same goal of cooling, there are a number of differences between evaporative air coolers and air conditioners. The main difference is that air conditioners use refrigeration to cool the air, whilst evaporative coolers do not. As a result, air conditioners produce colder air than is achieved with evaporative cooling.

Another major difference is the power usage required. Unlike power heavy air conditioners, evaporative cooling systems are environmentally friendly, and only use a small amount of electricity.

How do air coolers work?

Evaporative cooling only requires a supply of water and electricity to produce cool air, making them a safer and environmentally friendly alternative to air conditioners. As a result, this method of cooling is inexpensive to install and run, compared to an air conditioner installation.

A basic example of how evaporative cooling works is to imagine dipping your finger in water and holding it up in the wind. The wet part of your finger will feel colder than the rest of your finger, which is caused by the water evaporating.

Do evaporative air coolers actually work?

Yes, evaporative cooler systems can effectively cool your room, but a few factors that can impact their effectiveness. They typically produce the best results in areas with lower humidity. It is also important that the room has good airflow circulation to prevent the humidity building up and reducing the efficiency of the evaporative air conditioning system.

What is a Swamp Cooler?

If you are considering an evaporative air cooler, chances are you have come across the term Swamp Cooler. A swamp cooler is the same as an evaporative cooler, but the term is more often used in the United States, rather than in the UK.
