Talk to Our Engineering TeamFrequently Asked Questions
How much can I save switching from LPG to a heat pump for hot water?
Typical savings are 75-90% on hot water heating costs. A facility using 2,000 litres/day at Philippine energy rates saves approximately ₱480,000-626,000 per year compared to LPG, with a payback period under 1 year.
What COP does a heat pump achieve in the Philippines?
Karnot iHEAT R290 heat pumps achieve 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.
What is the free cooling bonus?
Every heat pump has a cold side (evaporator) and a hot side (condenser). While heating water, the evaporator produces free cooling that can offset air conditioning loads. This recovered cooling is worth ₱50,000-200,000+ per year depending on facility size.
Can I still use my existing hot water distribution?
Yes. The Karnot iHEAT connects to your existing hot water pipes and storage tanks. No changes to distribution are required — it replaces only the heat source.
What about Scope 1 emissions from LPG?
LPG combustion produces direct Scope 1 CO₂ emissions that must be reported under SEC PFRS S2. Switching to a heat pump eliminates Scope 1 heating emissions entirely, moving to lower Scope 2 grid emissions — and at 4x less energy consumption.
