Commercial heat pumps for centralised hot water
Splendid for centralised hot water systems, generating hot water up to 55 °C and a maximum of 60 °C. The ideal hot-water solution for hotels, hospitals, resorts, boarding schools and apartment complexes.
Is this the right range for you?
Two minutes here saves a wasted quotation. The boundaries below are the published ones, not sales judgement.
Yes, if all of these are true
- You need 1,000 litres a day or more at one place
- 55–60 °C is enough for your hot water
- Your coldest design morning is above about 5 °C
- You are burning diesel, LPG, PNG or electricity for hot water today
Look at another range if
- Your winter drops below 5 °C — see EVI Heat Pump
- You need water hotter than 60 °C — see High Temperature Heat Pump
- It is a home or a villa — see All in One Heat Pump
- It is a swimming pool — see Swimming Pool Heat Pump
Applications
Where this range is normally installed.
Key features
What is inside the cabinet, and why each of them is there.
American Copeland / Panasonic scroll compressor
The compressor is the machine. These are the two brands that hold their output through a decade of Indian duty cycles.
Automatic defrosting
Optional. Keeps output up through a damp winter morning instead of icing the coil and stalling.
Smart-touch control
Set point, schedule and fault history on the unit, without a laptop and without a service call.
Anti-corrosive coating
Coastal air and cooling-tower drift are what actually kill an outdoor coil.
Low noise and vibration
It usually sits on a terrace above occupied rooms. That is a design constraint, not a footnote.
HP / LP safety and stable running
High and low pressure cut-outs, and a control that rides through a voltage dip rather than locking out.

Benefits
What this range does for the building, rather than what is in the box.
Centralised to 60 °C
One plant instead of a geyser in every room — less equipment to buy, less to service, one thing to monitor.
Silent
No flue, no burner, no fuel delivery. A terrace plant room next to guest rooms is a normal installation.
Less maintenance
No combustion means no burner service, no flue cleaning and no fuel handling.
Where “up to 75 %” comes from
Our own commercial calculator, at its default 6,000 litres a day at 55 °C: the heat pump costs about ₹560 a day to run, an electric geyser ₹2,182 and a diesel boiler ₹2,492. That is 74 % against the geyser and 77 % against diesel — so the claim is, if anything, conservative. Put your own tariff and your own litres into the calculator and it will tell you your number rather than ours.
Size it yourself, in about a minute
Pick your building type, set the occupancy, and the calculator returns the kilowatts, the storage tank, the Sunniva model that covers it at your winter temperature, and what it costs to run against what you burn today.
And what every Sunniva heat pump gives you
True of the whole range, not just this one.
- Up to 75 % off water heating against electric, LPG or PNG
- Quick payback and strong return on investment
- The longest product life of any common water-heating technology
- Silent operation
- Hot water round the year, independent of sunlight
- Lower carbon emissions
- Negligible maintenance cost
- Saves space against a boiler or a solar-thermal field
Common questions
The ones our engineers are actually asked.
How much roof or terrace space do I need?
What happens on a cold winter morning?
Do I still need a storage tank?
Can I run more than one machine?
What electrical supply does it need?
