The Panasonic CU-TZ35CKE is a dedicated single-split outdoor unit, designed to pair 1-to-1 with the CS-TZ35CKEW indoor unit from Panasonic's TZ super-compact range. It uses the R32 refrigerant and an inverter-driven rotary compressor to deliver efficient heating and cooling for a single room.
Rated at 3.5kW nominal cooling and 4.0kW nominal heating, the CU-TZ35CKE reaches an SEER of 7.30 (A++) and an SCOP of 4.60 (A++), and is built as a compact, single-room condenser rather than a multi-split unit — unlike Panasonic's Free Multi Z range, this outdoor unit has no additional indoor connections.

Important: F-Gas Qualified Installation Required
This unit is charged with R32, a fluorinated greenhouse gas covered by F-Gas Regulations. Installation, commissioning, and any refrigerant handling must be carried out by an F-Gas certified engineer. See the certification form above before ordering.
Please Note: Dedicated Single-Room Outdoor Unit
The CU-TZ35CKE is a dedicated single-split outdoor unit designed to run exactly one indoor unit — the CS-TZ35CKEW. It does not support additional indoor connections. If more than one room needs conditioning from a single outdoor unit, a Free Multi Z outdoor unit such as the CU-2Z41CBE is required instead.
Good to Know: A++ Energy Efficiency
The CU-TZ35CKE achieves an SEER of 7.30 and SCOP of 4.60, both rated A++ on the current European energy label scale.
Dedicated 1-to-1 Pairing With CS-TZ35CKEW
Purpose-built to run the CS-TZ35CKEW indoor unit as a single-room system, without the added complexity or cost of a multi-split outdoor unit.
Inverter-Driven Rotary Compressor
The inverter compressor modulates output to match real-time demand rather than cycling on and off, which improves comfort, reduces electricity use, and lowers operating noise.
A++ Energy Efficiency
Achieves an SEER of 7.30 (A++) and an SCOP of 4.60 (A++), giving strong running cost performance for a single-room condenser.
R32 Refrigerant for Lower Environmental Impact
R32 has a lower global warming potential than the R410A refrigerant it replaces, while also improving system efficiency — helping the unit meet current and future F-Gas phase-down requirements.
Wide Heating Operating Range
Rated to operate in heating mode down to -15°C outdoor ambient, making it a genuine year-round heat pump solution for UK winters, not just a summer air conditioning unit.
Compact Footprint For Flexible Siting
At 542mm (H) x 780mm (W) x 289mm (D) and 30kg, the CU-TZ35CKE's compact dimensions make it easy to site on balconies, flat roofs, or against garden walls where space for outdoor plant is limited.

How many indoor units can I connect to the CU-TZ35CKE?
Just one. The CU-TZ35CKE is a dedicated single-split outdoor unit designed exclusively to pair with the CS-TZ35CKEW indoor unit — it does not support additional indoor connections.
Can I use this outdoor unit with a different indoor unit?
It is designed and rated as a matched pair with the CS-TZ35CKEW. For a system that supports multiple different indoor units, a Free Multi Z outdoor unit such as the CU-2Z41CBE would be the appropriate choice instead.
Does this outdoor unit need an F-Gas certified installer?
Yes. The unit is charged with R32 refrigerant, which falls under F-Gas Regulations. Installation and any refrigerant work must be carried out by an installer holding valid F-Gas certification, which we verify before shipment.
How efficient is the CU-TZ35CKE?
It achieves an SEER of 7.30 (A++) and an SCOP of 4.60 (A++) when paired with the CS-TZ35CKEW indoor unit.
Can this unit provide heating in cold UK winters?
Yes. The CU-TZ35CKE is rated to operate in heating mode down to -15°C outdoor ambient temperature, making it suitable as a genuine year-round heat pump rather than a cooling-only summer unit.
How far can the outdoor unit be sited from the indoor unit?
The system supports a pipe run of 3 to 15 metres, with a maximum elevation difference of 15 metres between the indoor and outdoor units.
