The CTC EcoAir C100 range has been launched in the UK by Go Geothermal.

CTC EcoAir C100 added to UK line-up

UK – Go Geothermal has introduced the compact CTC EcoAir C100 air source heat pump range to the UK market. Available in a black matt finish, the units are designed to complement multiple property styles whilst maintaining a discrete external presence.

The new range comprises four models – C106, C108, C112, and C116 – and the Swedish manufacturer says they 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.

  • 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: 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 is said to deliver 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 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.

In warm climate testing (W35/W55 EN14825, P.design1), the C116 delivers a Seasonal Coefficient of Performance (SCOP) of 6.67/5.00, whilst maintaining high efficiency in cold climates, with the C106 achieving 4.26/3.31.

Sound power ranges from 48-52 dB(A) and sound pressure at 5m distance measuring 29-33 dB(A), ensuring minimal disturbance to occupants and neighbours.

IP24 protection and professional installation

All models feature IP24 ingress protection, making them suitable for external installation whilst maintaining reliable operation. With rated currents ranging from 10A (13A) for the C106 to 22A (25A) for the C116, the units are designed for professional installation by qualified technicians.

Go Geothermal says it is supporting the launch with comprehensive technical support, next-day delivery, and high-quality training programmes at its UK training centres in Retford and Newton Aycliffe.
