About the SRF35ZS-W
The Mitsubishi Heavy Industries SRF35ZS-W is a premium 3.5kW floor-standing console indoor unit, engineered to deliver exceptional heating and cooling with a sophisticated, unobtrusive presence. Its elegant semi-flat front panel and stylish white finish allow it to blend seamlessly into a variety of interior designs, from modern homes to contemporary office spaces. With a slim depth of just 238mm and a height of 600mm, it is perfectly proportioned for installation on low or 'dwarf' walls. This makes it an ideal climate control solution for UK homes, especially in conservatories, loft conversions, and living rooms where conventional high-wall units may not be practical.
This unit represents a significant advancement in energy efficiency, embracing the latest R32 refrigerant technology. R32 has a much lower Global Warming Potential (GWP) compared to older refrigerants, reducing the system's environmental impact while delivering superior performance. The SRF35ZS-W proudly carries excellent energy labels, with an A++ rating for both cooling and heating modes. This high efficiency is quantified by its impressive seasonal ratings: a Seasonal Energy Efficiency Ratio (SEER) of 8.1 and a Seasonal Coefficient of Performance (SCOP) of 4.7. These figures indicate outstanding performance, translating directly into lower energy consumption and reduced electricity bills for your property throughout the year.
User comfort is at the core of the SRF35ZS-W's design. The unit features an intelligent dual air outlet system that optimises air distribution based on the operating mode. During heating, it intelligently prioritises the lower outlet to deliver a blanket of warm air at floor level. This warm air then naturally rises, using the principles of convection to create a comfortable, even temperature throughout the entire room, eliminating cold spots. Conversely, in cooling mode, it primarily uses the upper outlet to gently distribute cool air downwards, avoiding the discomfort of direct cold draughts. This automatic airflow selection ensures efficient and pleasant conditioning, whatever the season. For further personalisation, the "Flap Control System" allows users to precisely adjust the angle and position of the airflow flaps via the included infrared remote controller.
Air quality is another key focus. The SRF35ZS-W comes equipped as standard with an advanced Allergen Clear Filter. This specialised filter effectively captures and deactivates common airborne allergens like pollen, dust, and pet dander. The system is further enhanced by Mitsubishi Heavy Industries' innovative Natural Enzyme Filter, which is designed to destroy fungi and bacteria, and a Photo-catalytic Washable Deodorising Filter that neutralises unpleasant household odours. Together, these filters ensure the air you breathe is not just at the perfect temperature but also significantly cleaner and healthier.
Operation is remarkably quiet, making this unit an excellent choice for bedrooms, home offices, and other noise-sensitive environments. In its ultra-low cooling mode, the sound pressure level can be as low as 29 dB(A), which is comparable to a quiet whisper, creating a peaceful and relaxing atmosphere without disturbance.
Engineered for straightforward installation, the unit offers exceptional flexibility. Piping and drain hose connections can be made from six different positions on the unit, providing installers with multiple options to achieve a neat, discreet, and professional finish, regardless of the room's layout. While it includes a user-friendly remote, the system is also Wi-Fi ready (requires an optional adaptor), allowing for smart control via a smartphone or tablet.
Please note that this product is the indoor unit only and requires a compatible Mitsubishi Heavy Industries outdoor unit to function as a complete split system. In the United Kingdom, it is a legal requirement under F-Gas regulations that any stationary air conditioning system containing fluorinated greenhouse gases is installed by a certified F-Gas engineer. Employing a qualified professional is essential for safe, efficient operation and is a condition for validating the extensive manufacturer's parts warranty.
