The Worcester Bosch Climate 7000i-Set 26 E (part number 7733703119) is a 2.5 kW single-split air conditioning system delivering industry-leading A+++ energy efficiency in both cooling (SEER 10.1) and heating (SCOP 5.1) modes. Supplied as a matched indoor wall unit and outdoor condensing unit kit, it is ideal for living rooms, bedrooms, conservatories and home offices up to approximately 20–25 mΒ². The kit includes the Bosch Gateway G10-3 for instant HomeCom Easy app and voice-assistant control via Matter. Refrigerant pipework is not included β€” pipework must be sourced and installed by an F-Gas certified engineer.

πŸ”΄ F-Gas Certified Engineer Required. This system uses R32 refrigerant (GWP 675). By law, all refrigerant handling and system commissioning must be carried out by an engineer holding a valid F-Gas (Category I) qualification under UK F-Gas Regulations 2015. Part P electrical connection to the mains supply must also be completed by a qualified electrician.
🟑 No Pipework Supplied. This kit contains the indoor wall unit and outdoor condensing unit only. Refrigerant pipework is not included and must be sourced and sized separately by the installing engineer. Pipe diameters and maximum run lengths vary by model β€” refer to the specification table below and the Worcester Bosch installer guide before ordering pipe.
ℹ️ Gateway G10-3 Included as Standard. Unlike other models in the Climate range, the CL7000i ships with the Bosch Wi-Fi gateway in the box β€” no additional purchase needed. This enables immediate connection to the Bosch HomeCom Easy app and voice control via Amazon Alexa, Google Home and Apple Home using the Matter standard.
Industry-Leading Efficiency Ratings

With a SEER up to 10.1 and SCOP up to 5.3, the Climate 7000i achieves A+++ in both cooling and heating on the ErP energy label. The variable-speed inverter compressor modulates output continuously to match room demand, avoiding the energy waste and temperature swings that fixed-speed units produce.

Advanced Air Purification System

A dual-action bio filter and advanced ionizer work in tandem on every air pass. The ionizer actively renders airborne bacteria, allergens and volatile odour compounds harmless rather than simply trapping them in a filter β€” keeping indoor air quality high between maintenance intervals.

Smart Connectivity β€” Gateway Included

The Gateway G10-3 ships in the box, enabling immediate pairing with the Bosch HomeCom Easy app for remote temperature adjustment, weekly scheduling, fan speed and airflow direction control from any smartphone. Matter-certified for native voice control via Amazon Alexa, Google Home and Apple Home β€” no custom bridges or developer setup required.

Ultra-Quiet Operation

In silent mode the indoor unit drops to as low as 21–28 dB(A) β€” quieter than a whispered conversation β€” making this ideal for bedrooms, home offices and nurseries. In cooling mode, indirect ventilation angles the outlet grilles upward to distribute conditioned air without directing cold draughts at occupants.

Wide All-Year Operating Envelope

Heating mode operates reliably with outdoor temperatures down to βˆ’30Β°C; cooling is rated to ambient temperatures up to +50Β°C. Frost protection mode maintains the room above 8Β°C when the property is vacant in winter, without user intervention. Automatic defrost prevents ice build-up on the outdoor coil during cold snaps.

i-Clean Self-Cleaning & Energy Monitoring

i-Clean initiates a controlled freeze-thaw cycle on the indoor evaporator, using ice formation and melt to flush away accumulated dust and bacteria β€” maintaining peak heat-exchange performance between service visits. Real-time energy monitoring via the HomeCom Easy app reports kWh consumption per operating mode, helping occupants track running costs.

Frequently Asked Questions
Do I need a special qualification to install this unit?
Yes β€” two separate qualifications are required. Because the CL7000i uses R32 refrigerant, all refrigerant handling must be carried out by an engineer holding a valid F-Gas Category I certificate under the UK F-Gas Regulations 2015. Additionally, the mains electrical connection must be completed by a Part P qualified electrician. Failing to comply with either requirement is a legal offence and will invalidate the product guarantee.
Is refrigerant pipework included with this kit?
No pipework is supplied. The kit contains the indoor wall unit and outdoor condensing unit only. The installing engineer must source, cut and insulate the copper refrigerant lines on site. Pipe diameters differ between the 26/35 models (ΒΌ" liquid / β…œ" gas) and the 53 model (ΒΌ" liquid / Β½" gas), so check the specification table for your specific variant before ordering materials. Maximum pre-charged pipe run is 5 m; additional refrigerant charge is required at 12 g per metre beyond that.
What is the difference between the 26, 35 and 53 variants?
The suffix refers to nominal cooling capacity: 2.5 kW (26), 3.4 kW (35) and 5.0 kW (53). The 26 and 35 share the same indoor unit dimensions and the same outdoor unit casing; the 53 uses a larger outdoor unit. Heating capacity also scales: 4.1 kW for the 26 and 35, and 5.6 kW for the 53. As a general guide, allow approximately 100–140 W of cooling capacity per mΒ² of well-insulated UK living space, though a site-specific room load calculation is always recommended.
Is the Bosch HomeCom Easy app and Wi-Fi gateway included?
Yes β€” the Gateway G10-3 is supplied as standard with every CL7000i-Set. This distinguishes the 7000i from the 3200i and 5000i models, where the gateway is an optional extra. Once the gateway is installed and connected to the home router, the unit pairs with the Bosch HomeCom Easy app. Matter certification means you can also control it natively with Amazon Alexa, Google Home or Apple Home without downloading a separate manufacturer skill or app.
What does the up-to-7-year guarantee cover?
Worcester Bosch offers an up to 7-year guarantee on the CL7000i range β€” the longest offered on any unit in their Climate air conditioning portfolio. Terms and conditions apply; registration with Worcester Bosch is typically required, and the unit must be installed by a suitably qualified engineer. Refer to the Worcester Bosch website for current guarantee registration requirements.
Can the outdoor unit be wall-mounted or does it need to stand on the ground?
The outdoor unit can be either floor-mounted on a level, load-bearing surface or wall-mounted using appropriate bracket kits (available separately). The installation surface must be capable of supporting the outdoor unit's gross weight β€” 34 kg for the 26/35 models and 43.9 kg for the 53 model. Adequate clearance must be maintained around the unit for airflow and service access; consult the Worcester Bosch installer guide for minimum clearance dimensions.
