Round-the-clock hot water, without the boiler room

Hospitals, hostels, colleges and other campuses need hot water every hour of the day, for wards, kitchens, laundry and sterile services. Those loads run between 45 and 80 °C, where a heat pump delivers three to four units of heat for every unit of electricity, with no fuel deliveries, flue or combustion on site.

Where the heat goes in a hospital or campus

Hospitals run around the clock, so heat pumps work long hours and pay back quickly. Separate the loads by temperature and size each with storage.

DutyTemperatureWhat a heat pump does
Ward and patient hot water55–60 °CStored at 60 °C for hygiene, with a periodic higher-temperature cycle.
Hostel and staff quarters45–60 °CBulk sanitary hot water with morning and evening peaks.
CSSD pre-wash and washer-disinfectors40–75 °CPre-heated water reduces electric load on washers.
Hospital laundry60–80 °CWash water from a high-temperature heat pump instead of a boiler.

Worked example

A 200-bed hospital replacing electric water heaters

Wards, kitchen and staff areas at about 100 litres per bed a day: 20,000 litres a day heated from 27 to 60 °C, about 767 kWh of heat a day, every day of the year.

₹25.7 lakhElectric heaters, per year (₹9/kWh)
₹7.2 lakhHeat pump, per year (COP 3.5, ₹9/kWh)
₹18.5 lakhSaving per year

That load needs roughly 55 kW of heat pump running about 14 hours a day into storage. Because the electricity drawn falls to about a quarter, the same supply connection can carry more of the hospital’s other loads. Laundry and CSSD at higher temperatures are sized separately on a high-temperature machine.

Example only: bed occupancy, hot water use, tariffs and climate change the result. Use the calculator or send us your numbers.
Why Sunniva

Built for facilities that never close

Designed for continuous duty

Selections are sized for long running hours with storage, so the plant runs steadily rather than cycling.

No combustion on site

No fuel deliveries, storage, flue or boiler operator: a simpler and safer plant room.

Service across India

A nationwide service network, spares from our own factory, and remote support by video call.

Hygiene-friendly temperatures

Commercial and high-temperature machines store at 60 °C and above for safe hot water.

Made in our own factory

Designed and built in Asangaon, Maharashtra, so custom duties and replacement parts come from us directly.

Honest numbers

Capacity and COP come from our published datasheets at several ambient temperatures.

Questions we hear

Before you decide

Is a heat pump reliable enough for a hospital?

Yes, when the plant is designed with redundancy. We usually split the load over two or more machines, so one can be serviced while the others run, and size storage to ride through short interruptions.

What about Legionella control?

Store water at 60 °C and run a periodic higher-temperature cycle, with good circulation in the distribution loop. Our machines are built for 60 °C storage and high-temperature machines reach 80 °C.

Can it handle CSSD and laundry temperatures?

Pre-wash and laundry water up to about 80 °C comes from our high-temperature range. Final steam sterilisation still needs steam; a heat pump can preheat the feedwater.

Will it work on our existing electrical supply?

Often yes, because a heat pump draws roughly a quarter of the power of electric heaters for the same heat. We check the connected load and supply margin during sizing.

Can we keep the existing boiler or heaters?

Yes. Many sites keep them as standby for the first season. The heat pump plant connects ahead of them and takes the base load.

Send us your facility’s numbers

Beds or occupants, current heating method and monthly bill, and any laundry, CSSD or kitchen loads. An engineer will come back with a selection and an honest payback.

Example figures use stated assumptions and example tariffs; your site’s numbers will differ. Model selection and capacities are taken from our published datasheets; confirm the final selection with our engineers.
