Philippine Food Processors Pay ₱17/kWh for Steam Heat.
The Real Cost With iHEAT: ₱2.50.
Steam boilers run at 45-55% system efficiency after flue, blowdown, and distribution losses. iHEAT R290 and CO₂ deliver process heat to 90°C at COP 4.0 — a 78% cost reduction with sub-6-month payback.
Why Food Processors Are Replacing Boilers
Steam boilers are the largest energy cost in most Philippine food processing plants. Four factors are driving the transition to heat pumps.
Boiler Efficiency: 45-55% Real-World
Most steam boilers are rated at 80-85% gross efficiency, but real-world system efficiency — after flue losses, blowdown, condensate losses, and distribution — drops to 45-55%. Use our Boiler Energy Flow Analyser to see where your energy goes.
SEC PFRS S2 Compliance
Philippine listed food companies must disclose Scope 1 emissions. Diesel and LPG combustion in steam boilers creates direct Scope 1 liability. iHEAT eliminates on-site combustion entirely, simplifying climate disclosure under SEC PFRS S2.
Process Temperature Range
Many food processes operate at 60-90°C — well within heat pump range. Pasteurisation (72-85°C), CIP (85-90°C), tank heating (65-75°C), and blanching (70-85°C) can all be served by iHEAT CO₂ at COP 4.0, eliminating the need for steam entirely.
Production Reliability
Boiler failures halt production lines. iHEAT modular N+1 architecture means no single point of failure. Multiple parallel heat pump modules with iSTOR thermal buffer ensure continuous process heat even during maintenance or peak demand surges.
Process Temperatures Served by iHEAT
iHEAT CO₂ delivers precise temperature control to 90°C, covering the majority of food processing thermal loads.
Pasteurisation
HTST and batch pasteurisation for dairy, juice, sauces, and ready meals. Precise ±1°C control meets HACCP requirements.
CIP Washing
Clean-in-place hot water for process lines, tanks, and filling equipment. Eliminates the need for a dedicated CIP boiler.
Tank Heating
Jacketed tank heating for mixing, dissolving, and holding processes. Consistent temperature without steam coil fouling.
Recommended Products for Food Processing
Industrial-grade heat pump systems designed for continuous production environments.
iHEAT R290
6-350kW. COP 4.0-5.0. Primary process hot water to 65°C for tank heating, pre-heating, and domestic hot water.
iHEAT CO₂
High-temperature process heat to 90°C. COP 4.0. Pasteurisation, CIP, and sterilisation-grade hot water.
iSTOR
Phase-change thermal buffer. 33-80kWh. Absorbs demand spikes during batch processes without oversizing heat pumps.
iSAVE
Smart energy platform. AI load prediction, carbon reporting, and integration with SCADA/BMS for production scheduling.
Food Manufacturer, Bulacan
A food manufacturer in Bulacan replaced diesel-fired process heating across pasteurisation and CIP lines with Karnot iHEAT. The facility operates 16-20 hours per day, 6 days per week, with significant thermal demand for batch pasteurisation at 72-85°C and CIP at 85°C. The installation achieved a sub-6-month payback driven by the high utilisation hours and 78% reduction in thermal energy cost. Annual savings exceed ₱1.4 million.

Frequently Asked Questions
Can a heat pump replace a steam boiler in food processing?
Yes, for processes up to 90°C. iHEAT CO₂ delivers hot water at 90°C with COP 4.0, replacing steam for pasteurisation (72-85°C), CIP (85-90°C), and tank heating (65-75°C). Processes above 90°C still require steam but often represent only a small fraction of total thermal load.
What is the real cost per kWh of a steam boiler vs heat pump?
A diesel-fired steam boiler delivers heat at approximately ₱17/kWh when accounting for 45-55% real-world system efficiency. iHEAT delivers heat at approximately ₱2.50/kWh at Philippine electricity rates — a 78% reduction in thermal energy cost.
How fast is the payback for food processing heat pumps?
Due to high thermal loads and long operating hours (16-20 hours/day), payback periods are often under 6 months. A food manufacturer in Bulacan achieved sub-6-month payback on a full boiler replacement with Karnot iHEAT.
What about reliability and uptime?
iHEAT systems use N+1 modular architecture — multiple parallel heat pump modules ensure no single point of failure. iSTOR thermal batteries absorb demand spikes and bridge any maintenance windows, so production lines are never interrupted.
Does iHEAT comply with food safety standards?
Yes. iHEAT delivers precise temperature control within ±1°C, meeting HACCP, FDA Philippines, and ISO 22000 requirements. All wetted components are food-grade stainless steel, and the system maintains required pasteurisation hold times automatically.
