100kW Commercial Monobloc Air Source Heat Pump
Natural Refrigerant R290 · A+++ Rated · 3-Phase
The iHEAT 100kW is Karnot’s flagship large commercial unit — designed for district heating, large hotels, hospitals, industrial facilities, and anchor commercial buildings. Twin HITACHI inverter scroll compressors with dual DC fans deliver 100kW heating, 87.5kW cooling, and 75°C output. Multiple units cascade for loads exceeding 200kW, with G2½" water connections for high-flow commercial hydronic systems.

Virtual Power Plant Ready
Participate in demand response programmes, earning incentives by shifting commercial thermal loads during peak pricing periods.
Real-Time Performance Optimisation
Cloud-based models continuously tune system parameters, maximising COP and reducing operational costs by 15–25%.
Predictive Maintenance Analytics
Machine learning detects anomalies and predicts failures weeks in advance, reducing downtime and maintenance costs by up to 40%.
Solar PV Self-Consumption
Intelligent thermal storage optimisation maximises on-site solar use, reducing grid dependency and accelerating commercial ROI.
Tamper-Proof Data Integrity
Integrated UPS and cryptographic verification ensure auditable emissions tracking for ESG reporting and carbon credit certification.
Commercial Revenue Enhancement: iSAVE transforms heat pumps into revenue-generating assets through carbon credits, demand response payments, and reduced energy procurement. Typical installations see 8–15% additional annual returns beyond energy savings alone.

Commercial & Industrial Applications
The iHEAT 100kW delivers commercial-grade heating, cooling, and hot water from a single outdoor unit — replacing gas boilers with zero-combustion clean energy.
Commercial Buildings
Offices, hotels, schools, and healthcare facilities benefit from the 100kW’s high capacity, 75°C output, and A+++ efficiency.
Hydronic Efficiency
Water is 3,500× more efficient than air for thermal transfer — enabling zoned distribution and lower carbon footprint at commercial scale.
ESG & Sustainability
R290 + iSAVE blockchain monitoring provides auditable carbon data for ESG reporting, BREEAM assessments, and EPC improvements.
Commercial Benefits & ROI
The 100kW delivers compelling commercial economics — replacing gas boilers while improving energy performance, reducing carbon, and generating new revenue streams.
50–70% Energy Cost Reduction
Replacing gas heating with the 100kW typically reduces heating energy costs by 50–70% at current gas/electricity price ratios.
Cascade & Modular
Multiple units cascade for larger loads with lead-lag sequencing for efficiency and built-in redundancy.
Full Cooling Capability
87.5kW cooling via iZONE fan coils provides summer comfort — complete all-season climate from one outdoor unit.
Legionella-Safe Hot Water
75°C output meets BS EN 806 and L8 requirements for commercial hot water — no supplementary electric heating needed.
iSAVE Carbon Income
Blockchain-verified carbon credits generate ongoing revenue independent of government grant schemes, improving project IRR.
