Optima Water Solutions designs, supplies, and installs industrial and commercial Hot Water Systems in Kolkata — including solar water heating systems, heat pump systems, electric and gas-fired boilers, and heat exchanger-based HWS for hotels, hospitals, residential complexes, industries, and commercial buildings. ISO 9001:2015 certified with turnkey installation and AMC services.
An Industrial/Commercial Hot Water System (HWS) is a centralised system that heats and distributes hot water to multiple points of use within a facility. Applications range from domestic hot water supply in hotels and hospitals to process hot water for industrial manufacturing.
Modern HWS options include solar thermal collectors with storage tanks (most energy-efficient), heat pump water heaters (3–4x more efficient than electric), heat exchangers coupled to industrial waste heat, and gas/LPG-fired boilers for high-capacity instant hot water.
For large facilities in Kolkata, a properly designed HWS reduces energy costs by 40–70% compared to individual point-of-use heaters while ensuring consistent hot water availability across all outlets.
Facilities operating near Dankuni Industrial Complex, Kalyani Industrial Area, Falta SEZ in Kolkata face close scrutiny over wastewater discharge. West Bengal Pollution Control Board (WBPCB) mandates ETPs for industries and STPs for large housing projects in Kolkata.
Optima Water Solutions has built a track record of HWS installations serving Kolkata and the surrounding area, with local support for commissioning, operator training, and ongoing maintenance.

HWS cost in Kolkata depends on capacity and technology. A solar HWS for 500 LPD (suitable for a small hotel) costs ₹80,000–1.5 Lakh. A heat pump system for 5,000 LPD costs ₹4–8 Lakh. Large systems for 50,000+ LPD range ₹20–50 Lakh. Call +91 9711880791 for a load calculation and detailed quote.
Solar systems have zero running cost after installation but need direct sunlight — suitable for most of Kolkata except during extended monsoon periods. Heat pump systems work on electricity (3–4 units of heat per 1 unit electricity) and work regardless of weather. For Kolkata, a solar + heat pump hybrid system gives best reliability and lowest annual energy cost.
Yes. MNRE (Ministry of New and Renewable Energy) provides subsidies for solar water heating systems through state nodal agencies in West Bengal. Subsidy amounts vary by system size and type. Optima can help you navigate the subsidy application process for your Kolkata installation.
A standard flat plate collector (2 m²) produces 100–120 litres of hot water per day in Kolkata under normal solar conditions. Kolkata's average solar irradiation is 4–5 kWh/m²/day, making solar HWS highly effective for most of the year. A 5,000 LPD system for a hotel would require 40–50 collectors.
Yes. Optima offers comprehensive AMC for all HWS installations in Kolkata — covering solar collector cleaning, pump maintenance, valve servicing, control calibration, and emergency call-out. Regular AMC maintains system efficiency above 90% throughout the year.
