For hotels, hostels, PGs, hospitals and service apartments, hot water is a 24×7 necessity — and a major running cost. Diesel boilers and electric geysers are expensive to run. Commercial heat pumps deliver the same hot water using a fraction of the energy.
Why heat pumps are so efficient
A heat pump moves heat from the air into water instead of generating it. With a COP of 3–4, every unit of electricity delivers 3–4 units of heat. That's why running costs drop by up to 70% compared to electric heating.
Savings example: a 40-room hotel
| Electric geysers | Commercial heat pump | |
|---|---|---|
| Daily hot water | 3,000 L | 3,000 L |
| Approx. electricity / day | ~120 units | ~35–40 units |
| Approx. monthly cost (₹9/unit) | ~₹32,000 | ~₹10,000 |
| Typical payback | — | 1.5 – 3 years |
Indicative figures. Actual savings depend on occupancy, inlet temperature and tariff.
Sizing a commercial system
- Hotels: 60–100 L per room per day
- Hostels / PGs: 30–50 L per resident
- Hospitals: 50–100 L per bed plus kitchen & laundry
Kamal heat pumps with storage are available from 1000 L to 5000 L, and multiple units can be combined for larger loads.

For buildings with roof space, a Kamal FPC solar system with heat pump backup gives the lowest possible cost: the sun does most of the work during the day, and the heat pump guarantees hot water at night and during the monsoon.
Best practices
- Install a ring main with return line for instant hot water at every room.
- Soften hard water to protect heat exchangers.
- Use timers to heat during off-peak hours where ToD tariffs apply.
- Sign an AMC to keep COP high.
Frequently Asked Questions
Can a heat pump replace a diesel boiler?
For hot water up to ~60 °C, yes — at a much lower running cost and without fuel handling.
How much space does a commercial heat pump need?
Outdoor units need open airflow; terraces, podiums or service yards work well.
