What is the Legionella penalty?
Legacy heat pumps max out at 55°C, but Legionella bacteria can survive below 60°C. To meet the 65°C safety threshold, hotels must run expensive electric backup heaters to bridge the final 10°C gap. This “Legionella penalty” adds 15-25% to annual hot water costs. The Karnot iHEAT R290 delivers 75-90°C natively, eliminating this penalty entirely.
How does EaaS work for hotels?
Energy-as-a-Service (EaaS) means zero upfront capital expenditure. Karnot installs, owns, and maintains the iHEAT system. The hotel pays a guaranteed-lower monthly fee compared to their current hot water costs. This solves the operator vs owner split incentive problem — the operator pays less, and the owner pays nothing.
What COP does iHEAT achieve in the Philippines?
The Karnot iHEAT R290 achieves COP 4.0-5.0 in Philippine tropical conditions. Higher ambient temperatures of 28-35°C actually improve heat pump performance, making the Philippines an ideal climate for heat pump deployment.
Can solar PV charge the thermal battery?
Yes. The iSTOR PCM thermal battery stores midday solar energy as heat for use during evening peak demand. A 20 kWp solar array can offset 30-50% of the iHEAT’s electricity consumption, further reducing operating costs.
What about the split incentive problem?
In hotels, the building owner pays for CAPEX upgrades but the operator pays the energy bills. Neither party has full incentive to invest in efficiency. EaaS eliminates this — the operator gets a guaranteed lower monthly bill with zero CAPEX, and the owner pays nothing. Both parties benefit from day one.
