About the SRC20ZS-W
The Mitsubishi Heavy Industries SRC20ZS-W is a high-performance outdoor unit designed to be the engine of a premium split air conditioning system. As a component of the acclaimed Premium ZS series, this 2.0kW unit delivers exceptional cooling and heating, making it an outstanding choice for British homes, small offices, retail spaces, and other light commercial applications. Its combination of advanced inverter technology, energy efficiency, and quiet operation sets a high standard for modern climate control.
Engineered for superior efficiency, the SRC20ZS-W helps to significantly reduce energy consumption and lower electricity bills. It boasts an impressive Seasonal Energy Efficiency Ratio (SEER) of 8.5 in cooling and a Seasonal Coefficient of Performance (SCOP) of 4.6 in heating. These figures earn it a top-tier A+++ energy rating for cooling and an excellent A++ for heating, ensuring year-round comfort without the environmental or financial burden of less efficient models. This focus on efficiency makes it a smart, long-term investment for any property owner.
At the heart of its green credentials is the use of R32 refrigerant. This next-generation coolant has a Global Warming Potential (GWP) that is nearly 70% lower than the older R410A refrigerant. By choosing a system that uses R32, you are making a more responsible choice for the planet. Furthermore, R32's superior thermodynamic properties mean the system requires less refrigerant volume and operates more efficiently, contributing directly to its high performance and low running costs.
The SRC20ZS-W is designed to be unobtrusive. With a sound pressure level of just 45 dB(A) during standard operation, it is one of the quieter units in its class. This low noise output is comparable to a quiet library, ensuring it won't disturb you, your family, or your neighbours. This makes it particularly suitable for installation in dense residential areas or near sensitive spaces like bedroom or office windows. Its sleek, contemporary white casing has a smooth, minimalist profile designed to blend seamlessly into its surroundings, rather than being an industrial eyesore.
This outdoor unit provides a nominal cooling capacity of 2.0kW and a more powerful heating capacity of 2.7kW, making it perfectly suited for typical UK room sizes. It's part of a heat pump system, meaning it efficiently provides both cooling in the summer and effective heating in the winter. Its performance is reliable even in challenging weather, with a wide operating range that ensures comfort throughout the year. The unit's durable construction is designed to withstand the British climate, offering dependable service for years to come.
Installation flexibility is a key feature of the SRC20ZS-W. It supports a maximum pipe run of up to 20 metres and a vertical height difference of 10 metres between the indoor and outdoor units. This provides significant freedom in positioning the components for optimal performance and aesthetics. The unit comes pre-charged with refrigerant for pipe lengths up to 15 metres, simplifying the installation process. It is crucial to note that UK regulations mandate that all stationary air conditioning systems must be installed and commissioned by an F-Gas certified engineer. This not only ensures compliance with the law but is also essential for validating the manufacturer's warranty and guaranteeing the system's safety, efficiency, and longevity.

Frequently asked questions
What is the SRC20ZS-W?
The SRC20ZS-W is the outdoor component of a Mitsubishi Heavy Industries split air conditioning system. It works in conjunction with a compatible indoor unit to provide both heating and cooling for a single room or zone.
Why is R32 refrigerant a key feature?
R32 is a modern refrigerant with a significantly lower Global Warming Potential (GWP) than older refrigerants like R410A. It is also more efficient, which means the system uses less energy to run, resulting in lower electricity bills and a smaller carbon footprint.
Can I install this unit myself?
No. In the United Kingdom, it is a legal requirement that any stationary air conditioning system containing F-Gas refrigerants, like this one, must be installed by an F-Gas certified engineer. This ensures safety, compliance, and validates your warranty.
How noisy is this outdoor unit?
The SRC20ZS-W has a sound pressure level of 45 dB(A) during normal operation. This is very quiet for an outdoor unit, comparable to the sound level in a quiet library, making it suitable for residential properties where noise can be a concern.
