Product FAQs

Evaporative Coolers

How cold will the unit make a room?

Evaporative coolers do not have a thermostat built in and rely on a fresh air supply, provided by open doors and windows. They will usually bring the temperature down by a few degrees, likely in the region of 3-5 degrees less than the ambient temperature of the space it is used within. You may achieve cooler temperatures by adding ice to the water tray

Do they require water?

Yes! Evaporative coolers utilize water as the way to cool the air. They will usually still operate without water, but you will only get the same effect as a standard fan without water being used.

What is the difference between an Evaporative Air Cooler and an Air Conditioner?

There are many differences between these 2 products including price, weight, noise and many more. Although evaporative coolers do technically change the condition of the air, they are very different to an ‘air conditioner’. Air conditioners will allow you to set a desired temperature, whereas an evaporative cooler will only bring the room temperature down by a few degrees.

Portable Air Conditioning

Does the unit require installation?

Not any kind of proper/professional installation, they are more of a ‘plug & play’ set up. Simply remove the item from the box, attach the included hose to the rear of the unit and place the opposite end outside a window/door, then plug the unit into a power socket and switch the device on. Simple!

Do I need to keep windows and doors open or closed?

Air conditioning works best in a completely sealed environment, so to achieve the optimum results all windows and doors should be kept closed while the air conditioner is in operation.

Are the units loud?

During operation, most portable units will have a sound pressure of approximately 56dB (check manufacturers specification for full details). Because a portable air conditioner has all of the required components compressed into a compact design, they will never be as quiet as a fully installed system.

Does the unit require a water connection?

No, standard air conditioners and portable air conditioning units do not require a water connection.

What temperature will the unit achieve?

Due to legislation, most air conditioning products will only go as low as 18°c, but because they remove the humidity while operating, 18°c will feel very cold inside a sealed environment.

Will the unit require servicing?

Portable air conditioning units are not usually equipped with service valves, so do not require full services. However, they are fitted with mesh filters will do require regular cleaning to ensure sufficient air flow.

Air Conditioning Systems

Are Air Conditioning systems efficient?

Yes. When compared with an electric heater, air conditioning is roughly 4 times more efficient than plug in heaters. Most modern systems have a CoP (coefficient of performance) of 4 (roughly). So for every Kilowatt (kW) of energy used, it will produce roughly 4kW output. The majority of modern systems are a minimum of A rated, with many being A+ or higher.

Will an Air Conditioning system also provide heating?

Yes. Most modern (almost all) systems are known as ‘Heat Pumps’ which will allow the system to produce heating for the colder months and cooling for the warmer months – making Air Conditioning dual purpose.

Single split system or multi split?

This depends on the amount of rooms you wish to supply with cooling or heating.

Single-spilt systems are designed for 1 room or location. 

Multi-split systems are designed for multiple rooms, running 1 outdoor unit with multiple indoor units (with multi-split systems, all indoor units must be operating in cooling or heating mode simultaneously).

Does the indoor unit leak water?

The indoor unit will generate condensation, which is drained off with a condensate pipe to the outside of the building, so the indoor unit shouldn’t ever leak water inside.

Does it need a fresh water supply?

No. Air conditioning is a sealed system running refrigerant, so no plumbing for a water supply is required. Unless you choose to purchase a rare and very specific type of water-cooled system.

Are there any health risks / benefits?

There are rumours that air conditioning has been linked to Legionnaires Disease, but this is a complete myth and very untrue (with regard to sealed systems). As there is no standing water, Legionnaires does not apply to air conditioning. The internal (cleanable) filters on the indoor unit are designed to filter bacteria in the air, so actually promote good health with cleaner air.

What is the typical life span of a system?

This depends on the amount of usage the system has. For systems used for an average 8 hours per day (cooling in summer and heating in winter) and being maintained correctly, you should expect a minimum of 6 years reliable life. Most systems have a minimum 5 year warranty.

Does the system require a lot of maintenance?

The system should be serviced annually by an F-Gas registered engineer, which will keep the system running efficiently. Other than the annual service, the indoor unit should be cleaned every 1 – 3 months (depending on usage) and the outdoor unit should be cleaned every 6 – 12 months (again depending on usage) and can be tied into you annual service schedule.

Will the system dehumidify?

In cooling mode, the system will take the moisture out of the air, so will act like a dehumidifier also. This won’t happen in heating mode though (system effectively works in reverse during heating mode). There is also a ‘Dry’ mode, which will take water from the air per hour if it detects excessive humidity in the air. It is not designed to be a standalone dehumidifier.

Installation & Planning


Does an Air Conditioning system require professional installation?

Yes, by law all split type air conditioning systems will require an F-GAS registered engineer to carry out the installation (or at a minimum, a commissioning of the system). The exception to this rule is for products which can be found in our DIY category. These products are a monobloc design and can be installed by anyone with the ability to do so.

Do portable air conditioning units require installation?

Not any kind of proper / professional installation, they are more of a ‘plug & play’ set up. Simply remove the item from the box, attach the included hose to the rear of the unit and place the opposite end outside a window/door, then plug the unit into a power socket and switch the device on. Simple!


Do I Need Planning Permission For An Air Source Heat Pump?

As of December the 1st 2011 the laws have been relaxed on installation of air source heat pumps in England and Scotland.  This relaxation of the laws has been introduced to make it more appealing to people who want to have air source heat pumps installed and don't want to go through the rigmarole of applying to your local council for planning permission.

This is not an complete list of the regulations required for air source heat pump installations to be 'Permitted Developments' however it is a very good outline to follow.

England Regulations For Air Source Heat Pump Permitted Developments

Domestic heat pump installation will be classed as a Permitted Development, providing they comply with the following criteria:

  • There is no wind turbine at the property.
  • The external is less than 0.6 m3 (This is surprisingly large actually, the largest unit that we sell is roughly half of this).
  • The unit is more than one metre from the edge of the householder’s property (This means the unit has to be not within 1 meters of your neighbour’s property).
  • It is not on a pitched roof or near the edge of a flat roof.
  • Additional criteria will need to be met if the house is in a World Heritage Site.
  • This list is just an outline guide, you should read the full legislation here.

Scottish Regulations For Air Source Heat Pump Permitted Developments

Domestic installation of an air source heat pump in Scotland will be classed as a Permitted Development, unless:

  • It would result in the presence within the curtilage of a dwelling of more than one air source heat pump.
  • The air source heat pump would be situated less than 100 metres from the curtilage of another dwelling.
  • The air source heat pump is visible from the road in a conservation area.
  • The air source heat pump would be within a World Heritage Site or the curtilage of a listed building

In addition, before beginning the development the developer must apply to the planning authority for:

A determination as to whether the prior approval of the authority will be required for the sitting and external appearance of the air source heat pump.

Other conditions will also apply to ensuring installation of an air source heat pump will be a permitted development in Scotland.
