Technology comparisons. Plain English. Stated assumptions.

Side-by-side analysis of the technology choices that actually decide your bill — heat pump vs combustion, heat pump vs diesel/LPG payback, zero-export iVOLT vs net-metering. Every number traceable. Every assumption stated.

Combustion vs Heat Pump

The Carnot limit is two centuries old. The Karnot lever is the only way out.

Why every combustion engine is capped at ~60% efficiency, why heat pumps reach 450%, and what that means for your industrial heat bill.

Cost per kWh of Heat

Less carbon. Less pesos. Every kilowatt-hour of heat.

Cost per kWh of useful heat by technology at current Philippine prices: electric resistance ₱12.50, diesel ₱7.20, LPG ₱6.00, Karnot iHEAT ₱2.70, with iVOLT solar ₱0.50.

Solar Configuration

You sell at ₱6. You buy back at ₱14. That's not a market — that's a tax.

The 60% asymmetry between Blended Generation Charge and retail rate destroys the value of exported solar. Zero-export self-consumption with battery storage captures the full retail value.
