The Seven SS Stars 200L Non-Pressurized Solar Water Heater is a practical solar hot-water system designed for homes, small families, guest houses and low-pressure water systems.
It uses evacuated vacuum tubes to absorb solar heat and warm the water stored in the insulated tank, helping reduce electricity costs while providing reliable hot water for everyday use.
☀️ Key Features
- 🚿 Tank Capacity: 200 litres
- 💧 System Type: Non-pressurized
- ☀️ Heating Technology: Evacuated vacuum tubes
- 🧱 Durable metal support frame
- 🔥 Efficient solar heat collection
- 🧊 Insulated water-storage tank
- 🌞 Designed for rooftop outdoor installation
- 💧 Suitable for gravity-fed water systems
- 🏠 Ideal for domestic hot-water use
- ⚡ Helps reduce electricity used for water heating
- 🔧 Low-maintenance solar heating system
🔥 How It Works
The evacuated tubes absorb sunlight and convert it into heat.
That heat warms the water in the storage tank through natural circulation, allowing the system to operate without a separate circulation pump in a typical installation.
This provides:
- ☀️ Free solar water heating
- ⚡ Lower electricity consumption
- 🔥 Hot water during the day and into the evening
- 💰 Reduced ongoing energy costs
💧 Non-Pressurized Design
This model is best suited to gravity-fed water systems.
It is commonly used where:
- 🚰 Water comes from an elevated storage tank
- 💧 Household pressure is relatively low
- 🏠 A simple solar water-heating installation is preferred
- 🌾 The property is off-grid or in a rural area
For homes using booster pumps or high-pressure plumbing, a pressurized solar water heater is usually the more suitable option.
✅ Benefits
- 200L hot-water storage
- Uses free solar energy
- Reduces electricity bills
- Efficient vacuum-tube heating
- Simple gravity-fed operation
- Low maintenance
- Insulated tank helps retain heat
- Suitable for everyday household use

⚠️ Installation Notes
- ☀️ Install where the system receives strong direct sunlight
- 🧱 Ensure the roof or mounting surface can support the full system when filled
- 💧 Use with an appropriate gravity-fed water supply
- 🚫 Do not connect directly to unsuitable high-pressure plumbing
- 🔧 Professional installation is recommended
- 🧹 Clean the vacuum tubes periodically for better solar performance
- 🌍 Install appropriate plumbing and safety fittings

Questions and answers
Before you order
What is the capacity?
The system holds 200 litres of hot water.
Is it pressurized?
No. It is a non-pressurized solar water heater.
What heating technology does it use?
It uses evacuated vacuum tubes to collect solar heat.
Is it suitable for a family home?
Yes. A 200L system is suitable for many small-to-medium households, depending on daily hot-water use.
Does it need electricity to heat the water?
Its primary heat source is the sun, so normal solar operation does not rely on electricity.
Can it work with a rooftop water tank?
Yes. Non-pressurized systems are particularly suited to gravity-fed rooftop tank installations.
Can I connect it to a booster pump?
Not directly unless the system is specifically designed and protected for that pressure. For boosted or pressurized plumbing, a pressurized solar water heater is usually the safer choice.
