Heat pump water heaters extract ambient thermal energy from the surrounding air and use it to heat water — consuming 1 kWh of electrical energy to deliver 3.5–5 kWh of heat energy. This coefficient of performance (COP) of 3.5 to 5.0 represents a 75% reduction in electrical consumption compared to direct electric boilers running at COP 1.0.
Why Benchmark for Commercial Installations
Benchmark heat pumps are engineered and assembled in India for Indian climate conditions — ambient temperatures between 5°C and 45°C, which is the operating range that matters for Gujarat's hotels and hospitals. European heat pump brands often underperform in peak summer conditions; Benchmark maintains rated performance at 42°C ambient.
ROI Calculation
A 500-room hotel replacing a 100kW electric boiler with an equivalent Benchmark heat pump system reduces annual electricity consumption for water heating from approximately 250,000 kWh to 60,000 kWh — saving ₹15–20 lakh per year at commercial electricity tariffs. Payback period is typically 18–30 months.
