Fiidotherm supplies heat pump water heaters for residential, commercial and industrial use in Surat, as part of the Sudarshan Saur Shakti Group, manufacturing water heating systems in India since 1989.
Surat's year-round climate — warm to mild, favourable for heat pump efficiency
Dyeing & printing units in Surat's textile processing belt
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, 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 Surat’s warm-to-mild climate for most of the year 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 Surat business evaluating a long-term utility vendor, that combination of group track record and build detail matters more than a spec sheet alone.
Architects
The domestic line (up to 2,000 L/day, up to 4 COP) needs no rooftop collector space, runs quietly, and supports zoned delivery — practical advantages when specifying hot water for a bungalow or villa layout in Surat’s expanding residential suburbs.
Surat’s bungalow and villa growth is concentrated in corridors like Vesu, Pal, Adajan and Piplod, where plots are often narrower and roof space is already shared between solar panels, AC condenser units and overhead tanks. Consider a duplex bungalow in one of these pockets, where three bathrooms need reliable hot water in a tight morning window but there’s no roof space left for a solar collector sized to match — this is exactly the plot-space conflict a domestic heat pump manufacturer designs around, since the unit sits at ground or terrace level beside the AC compressor rather than competing for roof area.
Builders
For a mid-rise apartment project (illustrative example: 40–80 units), the commercial line scales from 20,000 L/day and above at up to 6 COP, sized centrally rather than unit-by-unit — a plant-room-based system that frees up rooftop space for other uses.
Surat has over 880 RERA-registered residential projects concentrated in Vesu, VIP Road, Dumas Road, Althan and Adajan, many of them mid- to large-size societies. A recurring challenge at this scale: individual electric geysers in every flat create a sharp, simultaneous morning power draw across the building and become an ongoing maintenance load for the society’s facility team. Working with a heat pump supplier to size one centralized system for the building’s total demand replaces dozens of individual units with a single system the society maintains once, not flat by flat.
Hospitality
Surat’s business hotels, serving visitors to its textile and diamond trade, run hot water as a constant, high-volume utility cost. The commercial line (20,000+ L/day and above, up to 6 COP) is built to that kind of continuous demand.
Surat’s hospitality demand clusters around Adajan and Athwa’s riverside hotels and serviced apartments, alongside a growing base of business travellers drawn by the Surat Diamond Bourse. A boutique hotel in this category typically sees sharp hot water demand at check-in and check-out hours, with quieter stretches in between — a pattern that leaves electric heaters either underpowered at peak or wastefully idle off-peak. A commercial heat pump supplier sizing for this kind of continuous-recovery demand builds around that uneven draw, rather than a single large instantaneous load.
Industrial
Surat’s dyeing, printing and finishing units — concentrated in belts like Sachin, Pandesara and Palsana — run continuous process-water baths. The industrial line (up to 50,000 L/day, up to 90°C) is built for exactly that duty, as an alternative to a boiler or immersion heater.
Multi-shift operation in this belt means hot water demand rarely stops through the day, and a common inefficiency is running a boiler continuously — even through shift changeovers or lower-volume stretches — for demand that isn’t fully there in that moment. As an industrial heat pump manufacturer, Fiidotherm sizes systems to run closer to actual load, rather than keeping a boiler at full temperature regardless of whether a full batch is being processed.
Swimming pools
Hotels, societies and resorts 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) rather than leaving it unheated outside peak summer.
Surat’s premium residential societies and clubs — concentrated in the same Vesu and Pal corridors as its upscale housing — increasingly include a clubhouse pool as a standard amenity, which typically sits unheated for a good part of the cooler months and becomes an underused amenity residents paid for. Sourcing a swimming pool heat pump from a supplier already serving Surat’s residential and hospitality segments extends that usable season without the running cost of a fossil-fuel pool 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 Surat’s denser residential and industrial plots.
Fiidotherm is expanding its Gujarat dealer network, and Surat — with its dense concentration of textile processing units and fast-growing residential construction — is a priority city. 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, architects and industrial buyers 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.
Yes — Surat’s climate is warm to hot for most of the year, with only a mild winter, which is generally favourable for heat pump efficiency since these systems draw heat from the surrounding air.
Fiidotherm’s industrial line is built for up to 50,000 litres/day at up to 90°C, which covers most process water requirements — but continuous multi-shift demand should be sized against your unit’s actual flow rate and duty cycle before specifying a system.
We’re actively building our Gujarat dealer network, including Surat. Contact us for current status.
A heat pump moves heat rather than generating it by combustion, which is inherently more energy-efficient for the same duty — the actual cost comparison depends on your current fuel type, consumption, and flow requirement, which we’d work through in a sizing assessment.
We’re prioritising Surat as part of our Gujarat expansion and are especially interested in partners already serving builders, architects and industrial buyers. Get in touch to discuss.
