The Innova 9HP Mini and the Innova 12HP are both compact air conditioning units, but they are aimed at different situations. The biggest difference lies in power and capacity: the 9HP Mini is ideal for smaller rooms and tight installation spaces, while the 12HP offers more cooling capacity for larger rooms. In this article, we answer the most frequently asked questions about both units so that you know exactly which one to choose. air conditioning fits best in your situation.

What are the main differences between the Innova 9HP Mini and the Innova 12HP?

The main difference between the Innova 9HP Mini and the Innova 12HP is the cooling capacity. The 9HP Mini delivers lower power and is designed for smaller rooms of roughly 20 to 25 square meters. The 12HP has more capacity and is suitable for rooms of 25 to 35 square meters. Additionally, the outdoor unit differs in size, which affects the installation space required.

In addition to capacity, there are also practical differences in weight and dimensions. The Mini variant is more compact and lighter, making installation in hard-to-reach places easier. The 12HP is slightly larger and heavier, but also delivers more cooling or heating per hour. Both units operate on the same principle: an outdoor unit and an indoor unit connected by pipes, requiring a wall penetration.

What drilling diameters are possible with the Innova 9HP Mini?

For the installation of an Innova 9HP Mini, a wall penetration with a diameter of 60 to 80 millimeters is typically required. This is the standard range for most monosplit air conditioners in the 9HP class. The exact diameter depends on the thickness of the pipes and the chosen installation method, but in practice, a hole of 65 or 70 millimeters is most frequently chosen.

Drilling this type of hole in concrete requires specific tools and the correct technique. A hole that is too small means pipes will not fit properly or will be damaged during installation. A hole that is too large causes drafts and heat loss. It is therefore wise to follow the manufacturer's and installer's recommendations for the exact size. If you use a price indication for drilling work to get an idea of what the throughput costs.

When is the Innova 12HP the better choice?

The Innova 12HP is the better choice when you want to cool or heat a room larger than 25 square meters, when the room is poorly insulated, or when there is a high heat load due to large windows or sunlight. In those cases, the 9HP Mini simply does not have enough power to reach and maintain the desired temperature.

Other situations where the 12HP is preferred:

Open living rooms or combined living and kitchen spaces
Spaces with high ceilings where the volume is greater than the surface area suggests
Workspaces or server rooms with additional heat sources such as equipment
Bedrooms or rooms that also serve as a home office

If you are unsure about the capacity you need, it is wise to have a calculation made based on the room volume, insulation value, and orientation. This prevents you from investing in a unit that becomes structurally overloaded or, conversely, is too large for the situation.

Is the Innova 9HP Mini suitable for use in occupied spaces?

Yes, the Innova 9HP Mini is perfectly suited for use in occupied spaces. The unit produces little noise, both the indoor and outdoor units, and its compact dimensions make it easy to integrate into a living room, bedroom, or home office. The Mini is particularly popular in occupied situations because it takes up little space and is visually less conspicuous.

When installing in an occupied space, it is important that the wall penetration is executed accurately. Vibrations, dust, and damage to the finish are things you want to avoid. Professional drilling ensures that the hole is straight, dust-free, and neatly finished. This is especially valuable in an occupied situation, as you do not want the installation to cause a nuisance in the living space.

Which drill fits your job: a checklist?

The right choice between the Innova 9HP Mini and the Innova 12HP depends on a number of specific factors. Use the checklist below to quickly determine which unit best suits your situation.

Area of the room: Less than 25 m²? Choose the 9HP Mini. Larger than 25 m²? Go for the 12HP.
Insulation: Well-insulated room with double glazing? The Mini is often sufficient. Poorly insulated or lots of glass? Choose the 12HP.
Ceiling height: Higher ceilings increase the volume, so more power is desirable.
Solar tax: Is the room exposed to a lot of direct sunlight? Then expect an increased heat load and choose a slightly larger size.
Outdoor installation room: Limited space for the outdoor unit? The Mini has a smaller footprint.
Sound sensitivity: Both units are quiet, but the Mini scores slightly better in indoor unit noise level.

If you are still not entirely sure after going through the checklist, it is wise to seek advice from an installer. Based on measurements and an inspection, they can make a targeted recommendation. Also, do not forget that the wall penetration is a crucial part of the installation: the correct diameter and a neat finish contribute to the efficiency of the air conditioner.
