About the SCM100ZS-W
The Mitsubishi Heavy Industries SCM100ZS-W is a high-capacity, highly flexible multi-split outdoor unit designed to provide comprehensive climate control for multiple rooms from a single, robust condenser. With a nominal cooling capacity of 10.0kW and a heating capacity of 10.5kW, this unit is an ideal solution for larger homes, small office buildings, and light commercial spaces across the UK that require tailored comfort in several distinct zones.
As the heart of a multi-split system, the SCM100ZS-W can connect to and independently control between two and five indoor units. This configuration eliminates the need for multiple bulky outdoor units, preserving the exterior aesthetics of your property and simplifying installation. You can mix and match a wide range of MHI indoor units, including sleek high-wall models, discreet cassettes, or low-level floor consoles, to create the perfect system for your specific interior design and functional needs.
Engineered for outstanding performance, the unit features Mitsubishi Heavy Industries' advanced inverter technology. The twin rotary compressor precisely adjusts its output to meet the exact demand from the indoor units, avoiding the inefficient stop-start cycles of older fixed-speed systems. This results in superior energy efficiency, stable temperature control, and significantly reduced running costs. The system boasts excellent seasonal efficiency ratings, ensuring it operates economically throughout the year, whether providing cooling during a summer heatwave or reliable heating through the cold winter months.
This model utilises R32 refrigerant, the modern standard for air conditioning. R32 has a Global Warming Potential (GWP) that is almost 70% lower than the previous generation R410A refrigerant. It also offers greater efficiency, meaning the system requires less refrigerant volume and consumes less energy to achieve the desired temperature, further reducing its environmental impact and your energy bills.
Installation flexibility is a key attribute of the SCM100ZS-W. It accommodates a total pipe length of up to 75 metres and a maximum vertical height difference of 25 metres between the outdoor and indoor units. This generous range provides extensive freedom in positioning the outdoor unit discreetly at ground level or on a flat roof, even if the indoor units are spread across different floors. The unit is pre-charged with enough refrigerant for a 40-metre pipe run, simplifying the installation process for many projects.
Designed for the variable UK climate, the SCM100ZS-W has a wide operating range. It can deliver effective cooling in ambient temperatures as high as 46°C and provide consistent heating even when outside temperatures drop to a harsh -15°C. This makes it a dependable, year-round solution for total home or office comfort. Despite its powerful output, the unit is engineered for quiet operation, with a sound pressure level of 54 dB(A) in cooling mode, minimising disturbance for both occupants and neighbours. It is essential to note that the installation of this system must be carried out by a qualified F-Gas certified engineer to ensure safety, compliance with UK regulations, and validation of the manufacturer's warranty.

Frequently asked questions
How many indoor units can be connected to the SCM100ZS-W?
The Mitsubishi Heavy Industries SCM100ZS-W outdoor unit can support between one and five indoor units, allowing you to create a customised climate control system for multiple rooms.
What type of refrigerant does the SCM100ZS-W use?
This unit uses R32 refrigerant. It is more environmentally friendly and energy-efficient than older refrigerants like R410A, contributing to lower running costs and a smaller carbon footprint.
Can I install this air conditioning unit myself?
No. In the United Kingdom, it is a legal requirement that any air conditioning system containing F-gases, such as R32, must be installed and commissioned by a qualified and F-Gas registered engineer.
Does this unit only provide cooling?
No, the SCM100ZS-W is a full heat pump system. It provides highly efficient cooling during the summer and reliable heating in the winter, capable of operating in outdoor temperatures as low as -15°C.
