Fan Coil Unit

Optimize your thermal comfort with a high-performance fan coil unit

Choosing the ideal fan coil unit for your office, business, or residential space isn't just a matter of design; it's primarily about finding a balance between thermal responsiveness and energy efficiency. At Climatik, we assist demanding professionals and individuals in selecting air treatment solutions that adapt to the actual configuration of their premises. Leveraging our expertise in HVAC engineering, our advisors guide you toward equipment from leading European manufacturers, always prioritizing the most coherent technical solution for your existing installation.

Understanding the three types of fan coil unit mounting

Cased fan coil unit: wall or floor installation The cased fan coil unit is the most common solution for renovating offices or apartments. Its main advantage lies in its ease of installation: it can be installed on a low wall (under a window) or vertically against a wall, like a conventional radiator. Equipped with an aesthetic casing, it blends discreetly into your interior decor. This system is particularly appreciated for its ability to distribute heat or coolness evenly thanks to its integrated fan which accelerates air circulation. The minor drawback remains the floor space it occupies, but modern ultra-flat models now minimize visual intrusion while maintaining high-level performance for living areas.

Ceiling or cassette fan coil unit: total space saving The cassette or ceiling model represents the ultimate discreet solution for tertiary environments such as meeting rooms or office floors. Its main advantage is its high position, which completely frees up wall and floor space. Installed directly in a false ceiling, the cassette diffuses air 360° (four-way models), ensuring a stable temperature without creating cold spots. It is the ideal option for large volumes where comfort must be the same for every occupant. The available power ratings can cover large areas, while condensate drainage is managed by an integrated pump, ensuring perfect compliance with the technical requirements of modern buildings.

Ducted fan coil unit: invisibility for comfort The ducted fan coil unit combines thermal performance with invisible aesthetics. Unlike cased models or cassettes, the unit is completely concealed in attics or technical false ceilings. Air is distributed via a network of insulated ducts and exits through simple grilles in the ceiling or at the top of the walls. This configuration is the preferred solution for luxury hotels or high-end residences because it eliminates any direct noise disturbance in the room. The essential aspect to remember is the need for a preliminary technical study for the sizing of the duct network to ensure silent and efficient airflow without pressure loss.

Which configuration for your thermal project?

For the renovation of individual offices or a dwelling, prioritize cased wall-mounted models. They allow old water radiators to be replaced without major work on the existing pipe network. This is the fastest and most economical solution to instantly benefit from air conditioning in summer and heating in winter.

For a shop, restaurant, or public sales area, the cassette fan coil unit is the most relevant choice. You benefit from powerful air diffusion capable of compensating for frequent door openings, while complying with ERP fire safety and accessibility standards.

For new projects or major renovations where aesthetics are an absolute priority, the ducted system is the way to go. It offers the best acoustic comfort on the market and can treat several zones simultaneously with a single indoor unit, while remaining completely invisible to occupants.

Regulation technologies: 2-pipe or 4-pipe?

Beyond the physical format, the hydraulic connection mode directly influences the flexibility of your installation. The 2-pipe system is the simplest: the entire installation is either in heating mode or in cooling mode. This is the standard configuration for residential housing.

The 4-pipe system (or 2-pipe / 2-wire) allows for much finer management. It offers the possibility of heating a north-facing room while air conditioning a south-facing meeting room within the same building. This technology is essential in modern tertiary buildings to guarantee the individual comfort of each employee throughout the day.

Questions about Fan Coil Unit?

Our experts answer your questions.

Does a fan convector consume more than a conventional radiator?

This question requires us to distinguish between the fan motor's consumption and the heat/cold production's consumption.

The motor's electricity consumption: a marginal cost
The integrated fan consumes very little electricity (generally between 20 and 50 watts, which is less than an old-generation light bulb). It is not this motor that impacts your bill, but the energy source that supplies the hot or cold water (heat pump or boiler).

Efficiency gain through air circulation

Unlike a static radiator that waits for heat to rise naturally (slow convection), the fan coil unit forces diffusion. It reaches the set temperature 3 to 4 times faster. By heating the usable volume more quickly, you reduce the periods of full-power operation of your thermal generator, which can lead to up to 15% overall energy savings.

The advantage of low temperature

The fan coil unit is designed to operate with water at 35-45°C, whereas a classic radiator often requires 60°C. This is where the real savings lie: your heat pump operates with much better efficiency (COP), drastically reducing your annual bill.

Can a fan heater be used for air conditioning without major work?

Oui, c'est l'un de ses atouts majeurs, mais sous une condition hydraulique stricte.

Le besoin d'une source de froid

Pour climatiser, votre réseau doit être alimenté par un groupe d'eau glacée ou une pompe à chaleur réversible. Si vous avez une chaudière seule, le ventilo-convecteur ne fera que brasser de l'air ambiant sans le refroidir.

La gestion des condensats : le point technique

En mode froid, de l'humidité va se condenser sur l'échangeur (comme une bouteille d'eau sortant du frigo). Il est impératif d'avoir une évacuation des condensats (un petit tuyau PVC) ou une mini-pompe de relevage. Si votre ancienne installation de radiateurs n'en possède pas, il faudra prévoir ce raccordement pour éviter les fuites.

Une solution plus saine que le split

Contrairement aux climatisations "Split" à détente directe, le ventilo-convecteur utilise de l'eau comme fluide caloporteur. C'est une solution plus écologique et souvent plus confortable, car l'air soufflé est moins "sec" et plus doux pour les occupants.

What maintenance does a fan coil unit require?

What is a virtual assistant? A virtual assistant is a professional who works remotely to provide administrative, technical, or creative assistance to clients. Virtual assistants can help individuals, businesses, and entrepreneurs with tasks such as scheduling appointments, managing emails, creating presentations, social media management, and much more. Their flexibility and ability to work from anywhere make them a valuable asset for those seeking to optimize their time and productivity.

How to choose between a 2-pipe and 4-pipe system?

The choice depends exclusively on the thermal flexibility you need in your building.

The 2-pipe system: residential economy

This is the standard setup. The entire building is either in heating mode or cooling mode. It's cheaper to purchase and install, but you can't heat a north-facing room if someone wants to cool a south-facing living room.

The 4-pipe system: tertiary comfort

Here, the unit has two separate coils (one for heating, one for cooling). You can have heating and cooling available simultaneously in the same unit. This is the ideal solution for offices or hotels where needs vary from room to room.
