Silica Solar brings to you an innovative solar water heater program!
The industrial, commercial and residential sectors in our country are faced with persistent natural gas shortage and hundreds of businesses have closed down on this account. The shortage of natural gas can be overcome by switching to Solar Water Heater (SWH) technology to supplement natural gas for heating water used in commercial, industrial and residential sectors. Solar water heaters absorb the sun’s radiation to heat water. Boiler feed water (BFW) and hot water supply systems can be heated near to boiling point with solar water heaters saving 40% to 60% natural gas.
Your SWH System will Help reduce Gas Load Shedding
The Project will Reduce Gas Load Shedding Solar water heaters used for boiler water preheating will save at least one third of natural gas required for your boilers. For example, a solar water heater system for a 4 tons/hour boiler will save 1.583 million cubic feet of gas per year. This gas saving during a year will conserve gas fields to fulfill peak gas needs for residential customers during winter months, thus avoiding gas load shedding for industrial customers

Solar Hot Water Systems
Solar thermal collectors use the suns heat to generate hot water. Even on cloudy days the collectors can supply the hot water. Solar hot water technology works on selective coating of vacuum tubes that convert solar radiation into thermal energy and heat water inside the tube, water inside the tubes flows into an insulated tank.
Solar Hot Water Assessment and Need Analysis
- Facility Hot Water Needs Analyzed for System Size
- Location Identified for Roof or Ground Mount System
- Structural Analysis Performed
- System Process flow Diagrams for Options Developed
- Natural Gas Savings Estimated for Cost Benefit
- System Proposed to Customer
- Installation agreement is signed
Solar hot water technology works on selective coating of vacuum tubes
that convert solar radiation into thermal energy and heat water inside the
tube, water inside the tubes flows into an insulated tank, while cooler
water in the tank flows down to the bottom of the vacuum tubes, causing
circulation throughout the system.
