Your hotel spends ₹8–15 lakhs a year on water heating. What if it were a quarter?
That’s a 100-room hotel running electric geysers year-round. Redstone’s RHP commercial heat pump water heaters, built in India and supported from Hyderabad, deliver the same 60°C hot water around the clock on up to 75% less electricity.

Heat pumps don’t generate heat. They move it.
Electricity bill for the same hot water
- ₹100 Electric geyser
- ₹25 Redstone RHP heat pump
Same tariff, same 60°C water. Based on up to 75% less electricity: the RHP delivers 3.5+ units of heat per unit of electricity, a geyser under one.
LPG and diesel boilers turn only 70–80% of their fuel into heat, and their cost follows fuel prices. Solar saves 60–75% in good weather but needs backup through the monsoon.
How a heat pump works
-
Evaporation
Outside air passes over the evaporator and the refrigerant absorbs its heat.
-
Compression
The Copeland Scroll compressor raises the refrigerant’s temperature.
-
Condensation
The Shell & Tube exchanger passes that heat into your water.
-
Expansion
Pressure drops at the expansion valve and the cycle repeats.
1 kWh electricity + 2–3 kWh free heat from the air = 3–4 kWh of hot water
