ISO 9001:2015 certified with turnkey installation and AMC services.
What is a Hot Water System?
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 Singapore, 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.
Hot Water System in Singapore — Why It Matters
PUB Singapore enforces world-class wastewater treatment standards. All industries must discharge to public sewer after pre-treatment. ZLD and water reclamation highly advanced. NEWater program recycles treated water. This makes properly designed HWS systems essential for operators in Singapore, particularly around Jurong Industrial Estate, Tuas Industrial Area, Seletar Aerospace Park.
Optima Water Solutions supports clients in Singapore with end-to-end HWS project delivery — from design and manufacturing to installation, commissioning, and long-term AMC support.

Common Questions
Hot Water System in Singapore — FAQ
What is the cost of a centralised Hot Water System in Singapore?
HWS cost in Singapore 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.
Which is better — solar hot water system or heat pump in Singapore?
Solar systems have zero running cost after installation but need direct sunlight — suitable for most of Singapore 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 Singapore, a solar + heat pump hybrid system gives best reliability and lowest annual energy cost.
Are solar hot water systems eligible for subsidy in Singapore?
Yes. MNRE (Ministry of New and Renewable Energy) provides subsidies for solar water heating systems through state nodal agencies in Singapore. Subsidy amounts vary by system size and type. Optima can help you navigate the subsidy application process for your Singapore installation.
How much hot water can a solar system produce in Singapore?
A standard flat plate collector (2 m²) produces 100–120 litres of hot water per day in Singapore under normal solar conditions. Singapore'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.
Do you provide AMC for hot water systems in Singapore?
Yes. Optima offers comprehensive AMC for all HWS installations in Singapore — covering solar collector cleaning, pump maintenance, valve servicing, control calibration, and emergency call-out. Regular AMC maintains system efficiency above 90% throughout the year.
