Heating Hot Water With a Steam Boiler Is a Terrible Waste of Energy
A steam boiler is the most expensive way to make 70 °C water. Adding a Karnot iHEAT R290 heat pump preheater cuts diesel use by 25% and pays back in under 18 months. Free calculator and Sankey tool inside.
Pinch Analysis Made Simple: Where Heat Pumps Save the Most
No jargon. No PhD required. Learn how pinch analysis finds the exact minimum heating and cooling your process needs — and where a Karnot Heat Pump saves the most money.
Your Steam Boiler Is Not 80% Efficient — The Real Number Might Shock You
Philippine factories are losing millions of pesos in hidden steam losses. Here is exactly where your energy goes — and what modern heat pump technology does instead.
Your Cold Store Is Burning 25-35% of Revenue on Electricity
Three hidden problems — defrost waste, refrigerant leaks, and non-condensable gases — are costing Philippine cold stores millions of pesos. Here is where the money goes.
Your Boiler Is Burning Money: CO2 Heat Pumps + MVR Cut Steam Costs 90%
Combining Karnot iHEAT CO2 heat pumps with Piller MVR turbo-compressors replaces fuel-fired boilers entirely — system COP of 10-15+ on electricity alone.
Your Hot Water System Is Costing You 4x Too Much
Philippine hotels, hospitals, and food factories are paying ₱12-16 per kWh of hot water. A heat pump delivers the same kWh for ₱2.50-3.00. Here are the numbers.
The humidity excursion you didn't see. The product you can no longer ship.
Standard split AC physically cannot hold a tropical warehouse at 22°C / 60% RH. The SHR mismatch story, the post-harvest loss it causes across tobacco / food / grain storage, and the AHU + iSTOR + R290 + solar architecture that fixes it.
You already have heat pumps. The gas inside is the problem.
R410A is on a phasedown clock under DENR DAO 2021-31. Salt air is destroying coastal coils. BOI incentives may apply. Here's the case for R290 replacement now, on capex.
The 10°C Penalty: Why Philippine Hotels Are Bleeding OPEX on Hot Water
Legacy heat pumps top out at 55°C. Legionella safety requires 65°C. That gap costs hundreds of thousands of pesos per year in electric backup.
