Fiidotherm supplies heat pump water heaters for residential, commercial and industrial use in Patna, as part of the Sudarshan Saur Shakti Group, manufacturing water heating systems in India since 1989.
Patna's subtropical climate — hot summers, mild but genuinely cool winter nights
Patna's fastest-growing residential and commercial corridors
Industrial line output, up to 50,000 L/day
Sudarshan Saur Shakti Group manufacturing legacy
Fiidotherm’s heat pump range covers five uses: domestic (up to 2,000 L/day, up to 4 COP), commercial (20,000+ L/day and above, up to 6 COP) for hotels and apartments, industrial (up to 50,000 L/day, up to 90°C) for process water, swimming pool heating, and space heating & cooling. Each line draws ambient heat from the surrounding air instead of burning fuel or relying on resistive heating, and Patna’s subtropical climate, with hot summers and a winter that turns genuinely cool at night, works in the technology’s favour. Tell us which use case applies to you and we’ll point you to the right product and sizing guidance.
Fiidotherm is the heat pump division of the Sudarshan Saur Shakti Group, which has manufactured solar water heaters in India since 1989 and is described by the company as India’s highest-selling solar water heater brand. The units are built with a Japanese/American-standard compressor, an electronic expansion valve for precise flow control, and a glass-lined, double-access storage tank designed to be cleaned rather than replaced. For a Patna business evaluating a long-term utility vendor, that combination of group track record and build detail matters more than a spec sheet alone.
Fiidotherm’s product range serves different needs across Patna — from a single bungalow to a commercial or industrial site. Find the section that matches your project below; each links to a fuller guide.
Architects
The domestic line (up to 2,000 L/day, up to 4 COP) needs no rooftop collector space and runs quietly — relevant for Patna’s bungalow-style residences, though this isn’t currently a priority segment for the city.
Patna’s established bungalow-style localities, including Boring Road and Patliputra Colony, carry many independent houses with private plots. A domestic heat pump supplier would apply the same plant-room-based logic here as elsewhere, but a dedicated local guide for this segment isn’t published yet; get in touch directly if this is your project type.
Builders
For a mid-rise apartment project (illustrative example: 30–60 units), the commercial line scales from 20,000 L/day and above at up to 6 COP, sized centrally rather than unit-by-unit.
Patna’s most active apartment corridors run along Boring Road, Bailey Road, Patliputra Colony and Kankarbagh — among Asia’s larger planned residential colonies — where new mid-rise societies continue to add units. A recurring challenge at this scale: individual electric geysers across dozens of flats create a sharp simultaneous morning power draw and an ongoing per-flat maintenance load. A heat pump supplier sizing one centralized system for the building replaces that scattered setup with a single system the society maintains once — genuinely relevant given how much of Patna’s real estate growth is happening in exactly this apartment-society format right now.
Hospitality
Patna’s hotels run hot water as a steady utility cost, and the commercial line (20,000+ L/day and above, up to 6 COP) is built for that continuous demand — though this isn’t currently a priority segment for the city.
Business hotels here cluster around Fraser Road and Bailey Road, serving Patna’s corporate and government-visitor traffic. The general commercial-line logic applies, but a dedicated local guide for this segment isn’t published yet; get in touch directly if this is your project type.
Industrial
Patna’s Patliputra Industrial Estate, near Bailey Road, hosts a mix of manufacturing and processing units, though this isn’t currently a priority segment for the city’s Fiidotherm content.
For a unit in the Patliputra Industrial Estate running continuous process-water needs, the industrial line (up to 50,000 L/day, up to 90°C) remains a relevant alternative to a boiler — get in touch for a sizing conversation if this applies to your business.
Swimming pools
Clubs and societies running a pool can extend the comfortable-use season with the swimming pool line (10,000 L/day to 20 lakh L/day, up to 32°C, titanium heat exchanger).
This isn’t currently a priority segment for Patna specifically, but the same logic applies to any pool operator in the city: a swimming pool heat pump extends the usable season through Patna’s genuinely cool winter nights without the running cost of a fossil-fuel heater.
A solar water heater is a strong option where a building has clear, unobstructed roof exposure — Sudarshan Saur Shakti has manufactured them since 1989, and this isn’t a case of one technology being talked down to sell another. A heat pump becomes the more practical choice where roof space is committed to other services, where a project needs a compact plant-room-based system, or where hot water demand needs to run independent of sunlight hours — common constraints in Patna’s denser residential plots.
Fiidotherm is expanding its North India dealer network, and Patna — as an emerging market with fast-growing apartment corridors along Boring Road, Bailey Road and Patliputra Colony — is a priority city with lower current competition than the network’s larger metros. We’re specifically looking to partner with existing high-end bathroom accessory suppliers and solar water heater dealers who already have trade relationships with builders in the city. If that describes your business, this is worth a direct conversation about territory, terms and how our existing group distribution can support you.
Mostly yes, with one honest caveat. Patna’s summers are hot (regularly above 40°C), which is favourable for heat pump efficiency, but winter nights (December–January) typically drop to around 6–12°C and have occasionally touched near-freezing in cold snaps — cooler than most cities in this network, though still short of the sustained sub-zero conditions where performance would need separate confirmation.
Fiidotherm’s commercial line scales from 20,000 litres/day and above at up to 6 COP, sized centrally for a building rather than unit-by-unit — relevant for the apartment growth along Patna’s Boring Road, Bailey Road and Patliputra Colony corridors. The right configuration depends on unit count and occupancy, which a sizing assessment would confirm.
We’re actively building our Bihar dealer network, including Patna. Contact us for current status.
Sizing depends on unit count and expected morning demand rather than the locality itself, but the mid-rise societies typical of these colonies generally fall within the commercial line’s 20,000+ litres/day range. A sizing assessment based on your project’s actual unit count would confirm the right configuration.
We’re prioritising Patna as part of our Bihar expansion and are especially interested in partners already serving builders, architects and industrial buyers. Get in touch to discuss.
