Solar water heating
Solar water heating (SWH) is the conversion of sunlight into renewable energy for water heating using a solar thermal collector. Solar water heating systems comprise various technologies that are used worldwide increasingly.
System Components
- Solar Thermal Collector
- SPOC Heat Dump Glycol Temp. / Pressure Protection
- PV Power Panel 10-20W
- 25’ Rubber Hose Line Set from roof to tank + up to 10′ of Collector return hose
- Pump and Analog Electronic Control Unit, PV Powered
- Patented “Solar Wand” Heat Exchanger (Double Wall) Screws into Your Hot Water Tank, Existing or New.
Applications
- Domestic : Flats, Bungalows and Apartments.
- Commercial : Hotels, Hospitals, Hostels and Dormitories.
- Industrial : Process Industries, Preheating boiler feed water.
Benefits
- These systems use solar energy which is a free and renewable source of energy (free because nobody owns the Sun and renewable because solar energy cannot be depleted like this is the case with fossil fuels for as long as our Sun keeps on shining.
- These systems use solar energy which help reduce our dependence on fossil fuels, improving our energy security and energy independence in the process by reducing the need for expensive foreign fuel import.
- In sunny and warm places with high insolation values solar water heating systems are very cost effective.
- Many countries around the world offer favorable incentives for the installation of solar water heating systems.
- Relatively good payback period, in average between 5-10 years
- These systems have low maintenance costs.
- You can build your own solar water heating systems (you can find the charts on how to build them on web).
- Some countries even offer the option of leasing solar water heating systems which can significantly decrease initial costs.
