Why hot water dominates a hotel energy bill
Guest showers, laundry and kitchen hot water run all day, every day. In a typical Indian hotel, water heating is second only to air conditioning on the electricity bill — and it is often the easiest big saving to make.
Conventional electric geysers turn one unit of electricity into one unit of heat. A heat pump uses one unit of electricity to move three to four units of heat from the ambient air into the water, so the same hot water costs a fraction as much to produce.
Sizing for real demand, not nameplate
A heat pump system is sized to the daily hot-water demand and the recovery rate needed at peak occupancy, with storage to buffer the morning shower surge. Oversizing wastes capital; undersizing means cold showers at peak, which is the one thing a hotel cannot afford.
We size from actual occupancy and fixture counts, not a rule of thumb, and we stage multiple units so part-load efficiency stays high.
Heat recovery: cooling and hot water from one system
In a hotel that is also running cooling, the heat rejected by the chiller or air conditioner can be recovered to pre-heat hot water — effectively free hot water for much of the year. It is one of the best combined-system savings available, and we design it in where the load profile supports it.
