Envirosun TS Solar Hot Water Systems Gold Coast
Premium stainless steel thermosiphon solar hot water systems designed for maximum solar performance and long-term reliability.
What Is The Envirosun TS Solar Hot Water System?
The Envirosun TS is a roof-mounted thermosiphon solar hot water system that uses natural convection to circulate water between highly efficient solar collectors and a rooftop storage tank. This design eliminates the need for mechanical pumps and helps maximise solar energy collection, delivering exceptional reliability and low running costs.

Contact Your Local DealerHow The Envirosun TS System Works
The Envirosun TS operates on the simple, proven principle of thermosiphoning. Because hot water is less dense than cold water, it naturally rises. The system leverages this physics to circulate water without any electrical pumps.
As the sun strikes the high-performance solar collectors, the fluid inside absorbs the heat. As it warms, it naturally rises into the insulated stainless steel storage tank mounted directly above the panels. Simultaneously, cooler water from the bottom of the tank flows down into the collectors to be heated.
This continuous, natural cycle ensures that the storage tank is constantly replenished with hot water throughout the day. Because there are no mechanical pumps or complex electronic controllers required for circulation, thermosiphon systems are incredibly efficient and highly reliable.
Envirosun TS Plus Key Features
High-Performance Collectors
Twin solar collector panels feature a large surface area with advanced selective coatings to maximize solar absorption, even on cloudy days.
444 Stainless Steel Tank
The 300-litre storage cylinder is constructed from premium 444-grade stainless steel, offering exceptional durability and corrosion resistance without needing a sacrificial anode.
No Circulation Pump
Relying purely on natural thermosiphon convection means zero energy is used for pumping, and there's one less mechanical component that could fail.
Versatile Boosting
Available with either an in-tank electric element or an inline continuous flow gas booster to guarantee hot water during extended overcast periods.
The Advantage of Stainless Steel Construction
One of the most significant advantages of the Envirosun TS system is its Type 444 stainless steel storage tank. Unlike traditional vitreous enamel (glass-lined) tanks, stainless steel offers distinct benefits that make it highly sought after by homeowners.
- Superior Corrosion ResistanceType 444 stainless steel is highly resistant to rust and corrosion, making it exceptionally durable and well-suited for the Gold Coast's coastal environments and salt air.
- No Sacrificial Anode RequiredBecause stainless steel naturally resists corrosion, it generally does not require a sacrificial anode. This eliminates the need for regular anode inspections and replacements, significantly lowering long-term maintenance costs.
- Lighter WeightStainless steel tanks are significantly lighter than glass-lined steel tanks, placing less structural stress on your roof framework during installation.
Benefits Of A Thermosiphon System
Thermosiphon solar hot water systems like the Envirosun TS are renowned for their simplicity and reliability. By eliminating the circulation pump and electronic controller found in split systems, the TS series offers a "set and forget" solution. Fewer moving parts mean fewer potential points of failure, resulting in lower maintenance requirements and dependable long-term performance.
Envirosun TS300 Specifications
Who Is The Envirosun TS Best Suited For?
The Envirosun TS300 is perfectly sized for typical family homes. It is an excellent choice for households of 3 to 5 people looking to drastically reduce their energy bills. It is best suited for properties with a strong, unshaded north-facing roof structure that can safely support the weight of the water-filled tank and collectors.
Why The Envirosun TS Performs Well On The Gold Coast
The Gold Coast's climate is ideal for the Envirosun TS. With high year-round sunshine levels, the highly efficient collectors can generate the vast majority of your household's hot water purely from solar energy.
Furthermore, the stainless steel construction provides vital protection against the corrosive coastal salt air found in suburbs from Paradise Point down to Coolangatta, ensuring the system outlasts many traditional mild-steel alternatives.
System Comparisons
Envirosun TS vs Heat Pump Hot Water Systems
Both are highly energy-efficient. Heat pumps extract heat from the air and are installed on the ground, making them ideal if roof space is limited or shaded. The Envirosun TS is completely silent, uses zero electricity for circulation, and can achieve even lower running costs in sunny climates, but requires robust roof support and good solar access.
Envirosun TS vs Split Solar Hot Water Systems
A split solar system places the tank on the ground and only the panels on the roof, using a pump to circulate water. While split systems look sleeker on the roof, the Envirosun TS (thermosiphon) eliminates the pump and controller. This makes the TS inherently more reliable and cheaper to maintain over its lifespan.
Electric Boosted vs Gas Boosted
The Envirosun TS can be fitted with an internal electric element that automatically kicks in if the water temperature drops (e.g., during winter storms). Alternatively, it can be paired with an inline continuous flow gas booster, which only ignites to top up the temperature as water flows to the tap, ensuring you never run out of hot water while maximizing gas efficiency.
Lifespan, Repairs & Replacement
How Long Does An Envirosun TS System Last?
Thanks to its 444 stainless steel tank and lack of moving parts, an Envirosun TS system typically lasts between 12 and 15+ years. Regular servicing of the PTR valves and booster components ensures it reaches its maximum potential lifespan.
Common Repairs & Maintenance
While highly reliable, occasional maintenance is required. Common repairs include replacing worn Pressure and Temperature Relief (PTR) valves, replacing faulty electric booster elements or thermostats, and addressing minor plumbing connection leaks. Because there is no circulation pump, you avoid the most common failure point found in split solar systems.
Signs It's Time To Replace Your Existing System
- Visible rust or water leaking directly from the storage cylinder casing.
- Consistently high electricity bills indicating the solar collectors have failed.
- Your current system is over 12-15 years old and requiring frequent repairs.
