The Aquasun 300L Pressurized Solar Water Heater is a high-capacity solar hot-water system designed for large homes, guest houses, apartments, offices, schools, hospitals and commercial properties.

It uses evacuated vacuum tube technology to capture solar heat efficiently and stores the heated water in a stainless-steel insulated tank. Its pressurized design provides stronger, more consistent hot-water delivery to showers and taps.

☀️ Key Features

• 🚿 Tank Capacity: 300 litres
• 💧 System Type: Pressurized
• ☀️ Heating Technology: Evacuated vacuum tubes
• 🧱 Inner Tank: Stainless steel
• 🛡️ Corrosion-resistant construction
• 🔥 Designed for strong solar heat absorption
• 🚿 Suitable for high-pressure showers
• 🚰 Suitable for distant taps
• 🧊 Insulated tank for improved heat retention
• 🌤️ Designed to continue absorbing heat during cloudy conditions
• 💧 Compatible with fresh water and borehole water
• ⚡ Optional electric booster can be added for low-sunlight periods
• 🌿 Helps reduce dependence on electric water heating
• 💰 Supplier claims potential power-bill savings of up to 75%, depending on usage and sunlight.

💧 Pressurized Hot-Water Delivery

Unlike a gravity-fed non-pressurized system, this Aquasun model is designed to maintain more consistent water pressure.

This makes it particularly useful for:

• 🚿 Modern showers
• 🛁 Multiple bathrooms
• 🚰 Mixer taps
• 🏠 Homes with pressurized plumbing
• 🏢 Commercial buildings
• 🏨 Guest houses and hotels

The supplier specifically notes that the pressurized system is intended to provide consistent flow even for high-pressure showers and distant taps.

☀️ Efficient Solar Heating

The vacuum tubes collect solar radiation and transfer the heat into the stored water.

Benefits include:

• 🌞 Reduced electricity consumption
• 🔥 Efficient hot-water production
• 🌤️ Useful performance during cloudy weather
• 💰 Lower everyday water-heating costs
• 🌿 Reduced dependence on conventional electric heating

🧊 Long Heat Retention

The insulated storage tank is designed to keep water hot after solar heating. The supplier states that hot water can remain warm for up to 48 hours, depending on weather and usage. 

✅ Benefits

• Large 300L hot-water capacity
• Pressurized water delivery
• Stainless-steel inner tank
• Suitable for borehole water
• Efficient solar heating
• Lower electricity consumption
• Good heat retention
• Suitable for multiple bathrooms
• Works in both urban and rural installations
• Optional electric backup available

⚠️ Installation Notes

• ☀️ Install where the collector receives good direct sunlight
• 🧱 Confirm the roof or structure can support the system when full
• 💧 Use correctly rated pressure and safety valves
• 🚿 Consider a tempering/mixing valve because solar-heated water can become very hot
• 🧹 Clean the vacuum tubes periodically
• 🧪 If using borehole water, regular descaling is advisable; the supplier recommends annual flushing to reduce scale buildup
• 🔧 Professional installation is recommended
• 🌍 Ensure all plumbing and pressure-relief components are installed correctly
