Solar water heaters use renewable solar energy to heat water for residential and commercial use. In Malaysia, where sunlight is abundant, solar water heating systems are an efficient and eco-friendly alternative to conventional electric or gas heaters. This guide will explain how a solar water heater works, the different types available, and why it’s an ideal choice for Malaysian homeowners.
How a Solar Water Heater Works
1. Solar Energy Absorption
- The solar collector (flat-plate or evacuated tube) absorbs sunlight and converts it into heat.
- This energy is used to heat water inside the system.
2. Heat Transfer to Water
- Thermosiphon Systems: Hot water naturally rises into the storage tank as cold water moves down into the collector.
- Active Pumped Systems: A pump circulates water between the collector and the tank for efficient heating.
3. Hot Water Storage
- Heated water is stored in a well-insulated storage tank to maintain temperature for extended periods.
- This ensures a consistent supply of hot water, even at night or during cloudy days.
4. Backup Heating System (If Needed)
- Many solar water heaters include an electric heating element as a backup for low sunlight conditions.
- This ensures uninterrupted hot water supply even during rainy seasons.
Types of Solar Water Heaters
1. Thermosiphon Solar Water Heater
- Uses natural convection to circulate water.
- No pump required, making it energy-efficient.
- Ideal for residential use with fewer moving parts and lower maintenance.
2. Active Pumped Solar Water Heater
- Uses a pump to circulate water between the collector and tank.
- Suitable for larger households or commercial applications.
- More efficient but requires additional energy for the pump.
Benefits of Using a Solar Water Heater
- Lower Energy Costs – Reduce electricity bills by utilizing free solar energy.
- Eco-Friendly Solution – Minimize reliance on fossil fuels and lower carbon footprint.
- Durability & Low Maintenance – Long lifespan with minimal upkeep.
- Consistent Hot Water Supply – Works efficiently in Malaysia’s sunny climate.
