Philippine Hotels Are Burning ₱2M+ Per Year on Hot Water.
There Is a Better Way.
Diesel at ₱119/litre. LPG up 40% in two years. iHEAT R290 delivers the same hot water at COP 4.0-5.0 in Philippine conditions — 75% less cost, zero fuel procurement, zero Scope 1 emissions.
Why Philippine Hotels Are Switching
Diesel boilers are the single largest controllable operating expense in most Philippine hotels. These four factors are accelerating the shift to heat pumps.
Diesel Price Volatility
Philippine diesel hit ₱119/litre in 2024 — an 83% spike in weeks. Hotels running 500-2,000 litre/month boilers face unpredictable OPEX that erodes room margins. iHEAT runs on grid electricity at a stable ₱10-12/kWh, delivering hot water at ₱3/kWh of heat.
SEC PFRS S2 Compliance
Philippine listed hotel groups must disclose Scope 1 emissions under SEC PFRS S2. Diesel combustion is a direct Scope 1 liability. Switching to iHEAT R290 (GWP 3) eliminates combustion emissions entirely and avoids HFC refrigerant disclosures.
Guest Sustainability Expectations
78% of international travellers prefer eco-certified hotels. GSTC, EarthCheck, and Green Key certifications require measurable energy reduction. Karnot systems provide verified carbon data via iSAVE for sustainability reporting and guest-facing dashboards.
Boiler Maintenance Burden
Diesel boilers require annual descaling, flue inspections, fuel tank compliance, and fire safety certifications. Heat pumps have no combustion chamber, no flue, no fuel storage — reducing maintenance costs by 60-70% and freeing up plant room space.

Aviation MRO Facility, Manila
An aviation MRO facility in Manila replaced its diesel-fired hot water system with Karnot iHEAT R290. The facility requires consistent 60°C hot water for parts cleaning and process heating across multiple hangars. Annual energy savings of approximately ₱400,000/year were achieved with a payback period under 3 years. Scope 1 combustion emissions from the hot water system were reduced to zero.

Frequently Asked Questions
How much can a Philippine hotel save with a heat pump?
A typical 100-200 room hotel saves over ₱626,000 per year by replacing diesel boilers with iHEAT R290. Larger resorts with pools and laundry facilities frequently exceed ₱2 million in annual savings. The exact figure depends on occupancy, hot water demand, pool volume, and current fuel costs.
What is the payback period for a hotel heat pump?
Most hotel installations achieve payback in under 3 years on a capital purchase. With Karnot Energy as a Service (EaaS), there is zero upfront cost — you pay a lower monthly energy bill from day one, with savings starting immediately.
Can iHEAT heat a swimming pool?
Yes. The iSPA range (6.5-39kW) is specifically designed for pool heating with COP up to 14.05 and titanium heat exchangers for saltwater resistance. For larger resort pools, iHEAT R290 units provide efficient year-round heating and can be integrated with the hotel domestic hot water system.
Does switching to heat pumps help with SEC PFRS S2?
Yes. Replacing diesel boilers eliminates Scope 1 combustion emissions from your hotel. R290 refrigerant has a GWP of just 3, avoiding the HFC-related Scope 1 disclosures that affect hotels using conventional DX cooling systems with R410A (GWP 2,088).
What happens during a power outage?
iSTOR phase-change thermal batteries store up to 80kWh of hot water energy, providing hours of backup without electricity. When paired with generator backup, the heat pump restarts automatically and the thermal store bridges the transition period seamlessly.
