Dairy Heat Pump Calculator
Monthly heating cost at COP 4 vs electric geyser — honest per-kWh-heat comparison.
Dairies pay twice — to chill milk and to heat wash water. A heat-recovery heat pump does both in one cycle (the chiller's waste heat IS the hot water). COP accounting here shows the double-dip saving.
A COP of 4 means each electrical unit delivers 4units of heat — the heat pump doesn't create energy, it moves it. The comparison divides electric geyser's fuel price by its efficiency for an honest per-kWh-of-heat contest.

Frequently asked questions
What does COP actually mean for my heating bill?+
Coefficient of Performance = heat delivered ÷ electricity consumed. COP 4 means each kWh you buy delivers 4 kWh of heat — the other 3 are pumped from outside air/ground for free. Your effective heat price becomes tariff ÷ COP: ₹8 electricity delivers ₹2/kWh heat.
Heat pump vs gas vs electric resistance — which is cheapest?+
Compare per kWh of HEAT: resistance = tariff (COP 1); gas = gas price ÷ ~0.9 efficiency; heat pump = tariff ÷ COP. At ₹8 power and COP 3.5, the heat pump delivers heat at ₹2.3 — beating most gas prices and demolishing resistance. This calculator runs your actual rates.
Do heat pumps work in very hot or very cold climates?+
Both, with caveats: cooling-dominated India is heat-pump natural territory (an AC IS one). For heating, modern cold-climate units hold COP ~2 at −15°C; ground-source sidesteps weather entirely via stable earth temperature. The system presets here carry climate-honest COPs.
Why is my real COP lower than the rated one?+
Ratings are lab points; seasonal reality includes defrost cycles, part-load behaviour, and your actual temperature lift. Field seasonal COPs run 15–25% under rated. Measure yours with the COP-from-bills approach: heat delivered (litres × ΔT × 1.16 Wh) ÷ metered kWh — the Dairy Heat Pump Calculator accepts your measured figure.
