Hot water and process heat,
at a fraction of the fuel bill

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.

The Sunniva range — domestic to 270 kW single machines

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, Customized, 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.

What changes when you switch

Owners rarely talk about COP. They talk about what stops happening on site, and what the monthly bill does.

No fuel at the gate

No diesel tanker, no LPG bank, no briquette yard. The heat comes from the outside air, and the only bill is electricity, about a quarter of what heaters or a diesel boiler would use for the same heat.

No boiler to watch at night

No burner, no flue and no combustion on site. The plant runs itself on a controller, and a stored tank of hot water covers the morning peak.

The old boiler becomes the backup

Most sites keep the existing boiler as a standby for the first season. The heat pump takes the everyday load from day one, and nothing is ripped out until it has proved itself.

₹17.8 lakhA 100-room hotel’s hot water on a diesel boiler, per year
₹4.3 lakhThe same hot water from a heat pump, per year
₹13.5 lakhBack in the business, every year

Example: 12,000 litres a day heated from 27 to 60 °C; diesel boiler 85% efficient at ₹90/L, heat pump COP 3.5 at ₹9/kWh. Your numbers will differ.

Why we started

Sunniva began with a question about energy, not a plan to build machines.

Kashyap Anandpara, founder of Sunniva
“It started as an instinct. In 2012 I wanted to do something in energy conservation. That was the whole of it.”

The decision was made on a trip to Leh in 2012, in a place where every unit of heat is precious and most of it still came from burning fuel. Heat that the air already holds seemed a better answer.

There was no plan to build machines, and no plan to build them in India. Both came later. Today Sunniva draws and builds its own heat pumps under one roof, more than five thousand of them are at work across India, and our service technicians still travel as far as Leh to look after them.

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.

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.

For end clients

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.

  1. Survey and loadWe measure the real draw-off — occupancy, fittings, peak hours, incoming water temperature — instead of sizing off a rule of thumb.
  2. System designMachine, storage, pumps, pipe sizing, electricals and plant-room layout, drawn before anything is ordered.
  3. Supply and installDelivered, positioned, piped, wired and commissioned by our own people or under our supervision.
  4. Handover and AMCYour staff trained on the controller, readings logged at handover, and a service contract if you want one.
For dealers and consultants

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.

  1. Design supportSend us the brief and our team sizes it with you — selection, storage, schematic and plant-room layout, under your name.
  2. Data and submittalsData sheets with capacity at every certified ambient, dimensions, electricals and clearance drawings — whatever the consultant asks for.
  3. CommercialA current channel-partner price list, quick quotations, and clear lead times you can commit to.
  4. 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.

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.

1 unit of electricity — the only part you pay for Outdoor air warm enough, even in winter 3 units of heat, free Sunniva heat pump 4 units of heat Hot water for the building Where the heat actually comes from Heat pump 4 units of heat Electric geyser 1 unit of heat electricity you pay for heat pulled out of the air, free Drawn at a COP of 4. Across our air-source range the published figure runs from about 3 to 6, depending on the machine, the water temperature and the weather — and every data sheet states which.
1

Evaporator

Ambient air — even cold air — boils the refrigerant and gives up its heat.

2

Compressor

The vapour is compressed, which raises its temperature well above the water you want to heat.

3

Condenser

The hot vapour gives that heat to your water and condenses back to a liquid.

4

Expansion valve

Pressure drops, the liquid cools below ambient, and the cycle starts again.

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.

Model selection

Not sure which model you need?

Tell our calculator about the job rather than the machine — the building, the pool or the process — and it works backwards to the plant. No form, no email wall, no salesman in the middle.

Describe the job

Occupancy, litres, pool size or process temperature. Whatever you actually know.

It sizes the plant

Duty in kilowatts at your design temperature, and the storage that goes with it.

It names the model

The Sunniva machine that covers it — and what it costs to run against what you burn today.
