The details
This wall-mounted all-in-one model is a great performer for year-round use as it works as a powerful air conditioner in the summer and a cost-effective heater in the winter. It functions as a dehumidifier too, which is great for keeping damp and moisture at bay. The air conditioner boasts an impressive BTU rating that's ideal for cooling spaces up to 35 sqm, without taking up vital floor space. The heater only requires a small amount of power to operate, which makes it an incredibly efficient way of heating your room, compared to electrical or central heating.
At only 20cm deep, it’s the same depth as many split indoor units on the market but with the added benefit of not requiring a separate bulky outdoor unit. Instead, it only requires two ventilation holes, making it ideal for conservatories, high-rise buildings or anywhere outdoor installation space is difficult to access. The R290 refrigerant gas is an energy-efficient refrigerant, an eco-friendly alternative with zero ozone depletion potential (ODP). R290 does also not require installation by an F-Gas certified engineer. Best of all, you can take control of all the functions from anywhere, at any time, using your smartphone. Simply connect the air conditioner to WiFi, download the app on your smartphone and away you go. Here are just a few things of what you can do:
Access anywhere - Switch on your air conditioner whilst at work, so that it's nicely chilled for when you arrive back home.
Control multiple devices - Take control of multiple air conditioners using a single app, ideal for commercial use in holiday homes or offices.
Easy to share - Give your family, guests or co-workers access to the device and its settings via simple QR code sharing.
Advanced scheduling - Set the air conditioner to automatically run at different temperatures at different times of the day. Scheduling saves you money as air conditioning will only operate when it is needed.
Alexa and Google Assistant compatible - Control the air conditioner using only your voice - "Alexa/OK Google, set living room temperature to 22°C."

Question from Julian.korek@gmail.com: Asked on 10/10/2025 Can this unit be fitted by a competent DIYer? Also what electrical feed is required?
Can it run off a ringbmain?
Hi Julian,Yes, installation of the electriQ iQool-Smart 15HP air conditioner is suitable for a confident DIYer, as it's a wall-mounted, ductless unit that is pre-gassed with R290 refrigerant (no F-Gas certification needed). Installation primarily involves securely mounting the 39kg unit and creating two ∼180mm ventilation holes through a solid, unobstructed wall before plugging it into a standard 13A socket. Always seek professional electrical help if you have any doubts.Thanks!
Question from Sj: Asked on 08/10/2025 Hi there. Is the unit eco friendly, cost effective and efficient?
Hi, The electriQ iQool 12000 BTU air conditioner is energy-efficient and eco-friendly, using a natural refrigerant that’s gentle on the environment. It has smart WiFi controls for easy, cost-effective operation and doesn’t need an outdoor unit, making installation straightforward.
Thank you.
Question from Theo: Asked on 07/10/2025 Is there a drawing showing where the vents are located in relation to the overall unit? Is there a minimum free air distance required for the vents as well? I am looking to install the unit but only have about 500mm until a low level wall (about 500mm high)?
Hi Theo, please leave at least 10 cm of space to the left and right of the machine; at least 20 cm of space must be left above the unit to help the air flow smoothly. A minimum distance of 50 cm is advised from the front of the unit. For vents, do not block or obstruct the air intake or exhaust vents during use to prevent overheating and damage. Lastly, you may want to visit the provided manual at this link for the product diagram: https://www.appliancesdirect.co.uk/files/pdf/IQOOL-SMART12HP-V2%20IQOOL-SMART15HP-V2%2020241223.pdf. Thank you.
Question from Mike: Asked on 20/09/2025 Could this be fitted to a static caravan?
Hi Mike,The electriQ iQool-Smart 15HP is an excellent choice for a static caravan because it provides both heating and cooling without requiring a bulky external unit; however, you must first confirm that your caravan satisfies the necessary structural and electrical demands, and professional installation may be advisable.Thanks!
Question from Steve: Asked on 14/07/2025 What is the maximum length of ducting on this unit? Could the supplied ducting be extended with regular 7" ducting?
The iQool 12?000 BTU is built for direct wall-through installation—it includes its own vent covers and ducting plates. You should not try to extend or adapt it with regular 7″ flexible ducting, as doing so would hinder airflow and could adversely affect performance and reliability.
Question from Paul: Asked on 14/07/2025 How close to the ceiling can the unit go
Hi, This unit must be installed on an external wall, as it vents directly out of its rear. Only install the unit on a flat, solid, reliable wall capable of supporting its weight. Ensure that there are no cables, pipes, steel bars or other obstructions behind the wall. Leave at least 10 cm of space to the left and right of the machine. At least 20cm of space must be left above the unit to help the air flow smoothly. A minimum distance of 50cm is advised from the front of the unit.
Thanks!
Question from Jason: Asked on 21/06/2025 Does this unit need an annual service?
Hi,No, the electriQ iQool 12000 BTU Wall Mounted Smart Air Conditioner with Heat Pump (IQOOL-SMART15HP) does not require an annual service by a technician for refrigerant. These units are sealed, meaning they do not need additional gas, and maintenance is limited to simply cleaning the filters.Thanks!
Question from Scott Wolff: Asked on 16/05/2025 What size is the vent duct? 4", 6" or bigger
Hi Scott,
Thanks for getting in touch,
This will be around 7 inches, you'll need to make the holes with a 180mm or 182mm core drill.
Hope this helps,
Sam
