New high-efficiency heating solution delivers luxury aesthetics from Sweden’s CTC at a cost-sensitive price point
Go Geothermal Ltd, the leading provider of ground and air source heat pump technology in the UK, has announced the launch of the CTC EcoAir C100 range.
The new CTC EcoAir C100 series complements the wide range of heat pumps from CTC, the renowned Swedish manufacturer with over 100 years of manufacturing expertise.
Combining powerful performance with a remarkably compact footprint, the range comprises four models – C106, C108, C112, and C116, designed to deliver exceptional heating performance whilst maintaining outstanding energy efficiency ratings. The three phase heat pumps are available in 8kW, 12kW and 16kW models, with the single phase also available as a 6kW model, in addition to the other outputs.
Darran Burrage, commercial director at Go Geothermal, said: “We are very excited to finally have these luxury aesthetics in a heat pump at a price point that allows us to enter cost sensitive sectors such as premium new build, social housing retro fit and ECO4. Having this new range in the Go Geothermal product offering allows us to assist more customers wanting to decarbonise their homes who do not want to compromise on quality.”
“The 16kW, single fan unit allows us to reach the semi commercial sector as well as larger domestic properties with multiple units being able to be cascaded.”
Outstanding Performance Across the Range
The CTC EcoAir C100 range offers comprehensive heating solutions for properties of all sizes:
- C106: Specified output up to 7.05kW with an impressive SCOP of 4.64 in average climate conditions
- C108: Delivers up to 11.52kW output with maximum airflow of 3,300 m³/h
- C112: Nominal output of 12.61kW, ideal for larger residential properties
- C116: The range-topping model offers up to 15.90kW output with airflow capacity of 6,100 m³/h
The C112 and C116 models achieve A+++ energy efficiency class ratings (W35/W55 A+++ to D) and C106 and C108 have A++, demonstrating CTC’s commitment to sustainable heating solutions. The units operate on standard 220-240V~50Hz electrical supply, C106 & C116 are also available in 3-phase. They feature low refrigerant charges (R290, GWP 0.02), with CO₂ equivalents ranging from just 0.000010 to 0.000032 tonnes.
Compact Design Meets Powerful Performance
The CTC EcoAir C100 range delivers impressive heating capacity without compromising on space and can operate with outdoor temperatures down to -22°C. Despite their powerful output, ranging from 7.05kW to 15.90kW, the units maintain remarkably compact dimensions from Compact dimensions from 458 (H) × 914 (W) × 708 (D) mm (C106) to 488 (H) × 1204 (W) × 1384 (D) mm (C116), with packaged weights between 70kg and 165kg. This space-efficient design makes installation straightforward for professional installers, even in properties with limited external space.
Available in a black matt finish, the CTC EcoAir C100 range combines aesthetic appeal with functionality, complementing a variety of property styles whilst maintaining a discrete external presence.
The range achieves impressive Seasonal Coefficient of Performance (SCOP) figures across all climate conditions. In warm climate testing (W35/W55 EN14825, P.design1), the C116 delivers a SCOP of 6.67/5.00, whilst maintaining excellent efficiency in cold climates with the C106 achieving 4.26/3.31.
Sound levels have been carefully engineered, with sound power ranging from 48-52 dB(A) and sound pressure at 5m distance measuring just 29-33 dB(A), ensuring minimal disturbance to occupants and neighbours.
