Steam Boiler Replacement ROI

What does your steam really cost — and how much of it is actually hot-water duty a heat pump could serve at a quarter of the fuel bill? Honest about the 75–90°C limit: the boiler keeps the true steam processes, the heat pump takes the rest.

1. Your Steam Boiler

Average during production, not nameplate
Real seasonal figure — usually 70–78
~85 with good condensate return · ~30 without
Diesel ₱/L · LPG ₱/kg · Gas ₱/m³ · Electric ₱/kWh

2. The Heat Pump Swap

Washdown, CIP, preheat, sanitation — anything ≤90°C
R290 to 75°C: 3–4 · CO₂ to 90°C: 3–4.5

Karnot iHEAT Selection

Calculation Method

Results are budgetary. Karnot's engineering team runs the full audit — steam metering, condensate survey, pinch analysis — free for qualified industrial sites. See also the Boiler Energy Flow Analyser and Feedwater Pre-Heat Calculator.

Built by Karnot Energy Solutions

Once you know the number, the next question is what serves it. Karnot builds R290 and CO₂ heat pumps for industrial hot water in the Philippines and worldwide — 9.5 to 100 kW, EN 378 design.

Burning diesel to make washdown water?

Most factories are. Karnot's free steam audit finds the share of your boiler load that a heat pump serves at a quarter of the running cost — measured, not estimated.
