Heat pumps, drawn and built
under one roof
Fourteen years designing and building heat pumps in Maharashtra, and five thousand of them now running across the country. We draw them, build them, test them and stand behind them — so the answer on sizing comes from the people who made the machine.
Heat pump range
Every Sunniva machine does the same thing — moves heat instead of burning something to make it — and what separates them is how hot they will take the water, and how much of it. So start with the temperature, then read down.
Bars show the maximum water outlet temperature only; capacity is printed beside them, not plotted. All in One, Monoblock, Domestic Split Unit, Geothermal, the dryer and the storage tanks publish no maximum outlet figure, so they are not on the chart — they are all in the bands below.
Hot water to 60 °C
Sanitary hot water, from a farmhouse to a campus5 ranges
Pool duty
Water held at swimming temperature, year round1 range
Hot water & process to 80 °C
Where a boiler used to be the only answer2 ranges
Industrial process heat
95 – 120 °C, without a boiler2 ranges
Ground coupled
A source that barely moves through the year1 range
Drying
The same cycle, pointed the other way1 range
Storage
Tanks that pair with any source2 ranges
Applications
Hot water, process heat, pool heating and space conditioning — wherever something is burning fuel or running an element to make heat the outside air could have provided.
Hospitality
Hotels, resorts and banquet kitchens
Developers & residential
Towers, apartments and villas
Hospitals & institutions
Wards, laundries, boarding schools
Swimming pools
Commercial pools, spas, therapy pools
Industrial process heat
Plating, CIP, dyeing, jacketed tanks
Geothermal & water source
Heating and cooling together
Working principle
A heat pump moves heat instead of making it. That single difference is why it returns three to four units of heat for one unit of electricity, which nothing that burns or glows can do. The picture first; the four components underneath, for anyone who wants them.
Evaporator
Ambient air — even cold air — boils the refrigerant and gives up its heat.
Compressor
The vapour is compressed, which raises its temperature well above the water you want to heat.
Condenser
The hot vapour gives that heat to your water and condenses back to a liquid.
Expansion valve
Pressure drops, the liquid cools below ambient, and the cycle starts again.
Benefits
Three reasons, in the order customers usually rank them.
Energy savings
A heat pump moves heat rather than making it, so it delivers three to four units of heat for one unit of electricity. Against a geyser or a diesel boiler that is where the running cost collapses.
Sustainable
No flue, no combustion, no fuel on site. Lower emissions than anything that burns, and lower still behind a rooftop solar array.
Low maintenance, long life
No burner to service, no flue to clean, no fuel to handle. Fewer moving parts than a boiler and a working life measured in decades.
Support
Two very different customers, and we are set up for both: the client who wants hot water and one number to call, and the dealer who owns the relationship and needs real engineering behind him.
Turnkey, and one number to call
You are buying hot water, not a heat pump. We take the job from the first site visit to the annual service, and stay the single accountable party the whole way.
- Survey and loadWe measure the real draw-off — occupancy, fittings, peak hours, incoming water temperature — instead of sizing off a rule of thumb.
- System designMachine, storage, pumps, pipe sizing, electricals and plant-room layout, drawn before anything is ordered.
- Supply and installDelivered, positioned, piped, wired and commissioned by our own people or under our supervision.
- Handover and AMCYour staff trained on the controller, readings logged at handover, and a service contract if you want one.
We design it with you, and stand behind it after
You own the customer. We give you the engineering, the paperwork and the service backup so you can quote with confidence and not get caught out on site.
- Design supportSend us the brief and our team sizes it with you — selection, storage, schematic and plant-room layout, under your name.
- Data and submittalsData sheets with capacity at every certified ambient, dimensions, electricals and clearance drawings — whatever the consultant asks for.
- CommercialA current channel-partner price list, quick quotations, and clear lead times you can commit to.
- After-salesSpares and service wherever you sell, plus training for your own engineers so first-line calls stay with you.
Neither promise means anything without people on the ground to keep it. That is what the numbers above are for.
Factory
Made in India is a supply chain here, not a sticker. Our own design team draws the machine and our own line at Asangaon builds it — including the ceramic-lined storage vessels. That control is why a non-standard duty is a conversation rather than a refusal, and why six days is a lead time we can actually offer.
Designed in-house
Our own design team draws the machine, the cabinet and the control. A non-standard duty is a conversation, not a refusal.
Built in-house at Asangaon
Assembly, brazing, wiring and test under one roof in Maharashtra — including the ceramic-lined storage vessels that go with the machines.
Tested before it ships
Every unit is run and logged before it leaves. Rigorous inspection is the only reason a six-day lead time is safe to offer.
Supply chain and logistics
Components from established brands, each with its own test report, and freight partners who move plant rather than parcels.
People
Forty-seven people, most of them in Maharashtra. Two of them run the company and are easy to reach; the rest are the reason an order gets designed, built, delivered and serviced.
