Daikin Perfera FTXM25A 2.5kW Wall Mounted Multi-Split Indoor Unit

Daikin Perfera FTXM25A 2.5kW Wall Mounted Multi-Split Indoor Unit

The Daikin FTXM25A is a 2.5kW wall mounted indoor unit from the Perfera range, designed for connection to a Daikin multi-split outdoor condenser (such as the 2MXM, 3MXM, 4MXM or 5MXM series, sold separately) alongside other indoor units. It combines Daikin's Perfera styling and quiet operation with the flexibility of a multi-split system, allowing several rooms to be air conditioned from a single outdoor unit.

Supplied as the indoor unit only, for connection to a compatible Daikin multi-split outdoor unit by an F-Gas certified installation company.

Key Features

• 2.5kW nominal indoor unit, wall mounted format
• R-32 refrigerant
• Indoor sound pressure from 21 dBA on silent mode
• 4-speed fan operation (High / Medium / Low / Silent)
• Designed for connection to a Daikin multi-split outdoor unit alongside other indoor units
• Compact footprint: 298 × 804 × 252 mm

Benefits

• Multi-room flexibility — combine with other Daikin Perfera indoor units on a single multi-split outdoor unit for independent room-by-room control.
• Whisper-quiet operation — indoor sound pressure from 21 dBA on the lowest fan speed makes it suitable for bedrooms and home offices.
• Compact wall-mounted design — low-profile cabinet suits most room layouts.
• R-32 refrigerant — lower environmental impact than older refrigerants.

Suitable Applications

• Single bedrooms and smaller rooms as part of a multi-split system
• Home offices and studies
• Multi-room installations alongside other Perfera indoor units
• Retrofit projects adding a room to an existing multi-split system

Technical Specifications

Outdoor unit dimensions, weight, SEER/SCOP and energy label depend on the multi-split outdoor unit selected and the combination of connected indoor units, and are listed on that outdoor unit's own product page — for example our Daikin 3MXM40A8 multi outdoor unit.

Room Size Guide

As a general guide, the 2.5kW FTXM25A is suitable for rooms of approximately 15–25 m², subject to insulation standard, glazing, ceiling height, solar gain and occupancy. For commercial applications or rooms with unusual characteristics, a qualified engineer should carry out a full heat load calculation in accordance with CIBSE guidance.

Frequently Asked Questions

Does this listing include an outdoor unit?
No. This listing is for the FTXM25A indoor unit only. A compatible Daikin multi-split outdoor unit, such as our 3MXM40A8, is sold separately.

Can this be used on a mono-split system?
The FTXM25A is a multi-split indoor unit. For a single-room mono-split installation, see our Daikin Perfera wall mounted system listings, which include a matched outdoor unit.

Does this system include installation?
No. This listing is for the equipment only. Installation must be carried out by an appropriately F-Gas certified installation company.

What refrigerant does this system use?
R32. This is a lower global warming potential refrigerant compared to R410A. Handling requires F-Gas certification.

Can this unit heat as well as cool?
Yes, when connected to a Daikin multi-split heat pump outdoor unit, the FTXM25A provides both cooling and heating.

What size room is this suitable for?
As a general guide, 15–25 m². However, room sizing depends on multiple factors. A heat load calculation is recommended for accurate sizing.

What pipe sizes does this unit require?
1/4" (6.4 mm) liquid line and 3/8" (9.5 mm) gas line.

How quiet is this unit?
From 21 dBA on the silent fan setting, rising to 45 dBA on high fan speed.

Is a local isolator required?
Yes. A local isolator switch is required by Part P of the Building Regulations and should be installed by a qualified electrician.

Professional Installation Required

This air conditioning indoor unit must be installed and commissioned as part of a complete multi-split system by an appropriately F-Gas certified installation company. Installation, pipework, electrical connection and commissioning are not included in this listing unless separately agreed in writing. Handling of R32 refrigerant requires appropriate F-Gas certification under UK F-Gas Regulations.
