The Envirosun AS315/40 Active Split Solar Hot Water System is a split solar hot water system designed for homes wanting higher-capacity solar hot water with a ground-level storage tank and roof-mounted collectors. It uses a 315 litre storage tank in the Envirosun AS active split range, making it a practical option for buyers comparing Envirosun AS315/40 installed pricing, Envirosun AS315/40 supply and install, or hot water replacement in Brisbane. Unlike a close coupled solar system, the tank and collectors are installed separately, with a circulation pump moving water between them.
The Envirosun AS315/40 Active Split Solar Hot Water System is a split solar hot water system. That means the storage tank is installed at ground level while the solar collectors are mounted on the roof, and the system uses an active pumped circulation setup to move heat from the collectors back into the tank. This style of solar system gives more flexibility than a roof-mounted tank system and is designed to suit a wide range of Australian homes and climates.
The Envirosun AS range uses Australian made enamel-lined mild steel storage tanks with anode protection, a European-made pump, a German-made controller, and a full valve package supplied for installation. As a 315 litre version, the AS315/40 sits above the 250 litre model and is better suited to homes that need stronger stored hot water capacity for family use while still keeping the tank off the roof.
One of the main reasons people choose the Envirosun AS315/40 Active Split Solar Hot Water System is because it combines solar water heating with a practical split system layout and larger storage capacity. The 315 litre storage size can suit homes that need more stored hot water than a smaller system can comfortably provide, while still giving the flexibility of a ground-level tank and roof-mounted collectors only.
This model also suits buyers who want a more refined solar setup rather than a basic solar package. The Envirosun AS range is built around an Australian made storage tank, a high-quality controller, a European-made pump, supplied safety and control valves, and either electric or gas booster compatibility. It is designed to deliver high-pressure hot water, quiet pump operation, and practical day-to-day performance while still focusing heavily on solar energy savings.
The Envirosun AS315/40 Active Split Solar Hot Water System can be a strong fit for homes wanting solar hot water with a separate ground-level tank and roof-mounted collectors. It is generally well suited to family homes and households that want the flexibility of a split solar system but need more stored hot water than a smaller 250 litre system would usually provide. It can also be a practical choice where the roof suits solar collectors but the ground-level tank position is easier to service and integrate with the home.
As with any solar hot water system, suitability depends heavily on the site. Roof space, collector orientation, pipe run distance, tank location, circulation pump setup, available access, and booster arrangement all matter. Final installation scope depends on what is already at the property. Some jobs are straightforward replacements, while others may require extra works. Depending on the site, that may include roof mounting arrangements, pipework alterations, booster integration, valve upgrades, tempering requirements, electrical work for the pump or electric booster, or changes to suit the final tank location.
A cheaper hot water system is not always the better buy once installation complexity, long-term efficiency, durability, and actual site suitability are taken into account. Solar hot water especially needs to be judged on more than just upfront product price. The wrong system for the roof, boost arrangement, or plumbing layout can quickly become poor value.
The Envirosun AS315/40 Active Split Solar Hot Water System is designed as a genuine solar hot water solution with a split system layout, an Australian made storage tank, advanced controller and pump hardware, and supplied valves needed for installation. The bigger issue is installation suitability. Even a good solar system can become the wrong choice if the collector position, pipe runs, boosting arrangement, or tank location are not properly planned. That is why JR Gas & Water focuses on the overall installation result, not just the unit itself.
JR Gas & Water provides professional Envirosun AS315/40 Active Split Solar Hot Water System installation in Brisbane & Gold Coast, with the installation assessed around the roof layout, current hot water setup, pipework path, booster requirements, tank location, and the home’s actual hot water usage. Whether it is a solar hot water replacement in Brisbane or hot water installation on the Gold Coast, the goal is to make sure the system suits the site rather than forcing a solar model into the wrong property conditions.
We also service surrounding areas including Logan, Ipswich, Moreton Bay and Redlands. Our approach is practical and installation-led. That means checking whether the roof is suitable for the solar collectors, whether the ground-level tank location is workable, whether access is safe and practical, and what extra works may be required to complete the installation safely and compliantly.
Installing the Envirosun AS315/40 Active Split Solar Hot Water System is very different from installing a ground-level electric storage system or a close coupled solar unit. The storage tank stays at ground level while the solar collectors are mounted on the roof, and a small circulation pump moves heat between them. That means the installation needs to account for roof collector placement, tank location, pump operation, control setup, pipe runs between the roof and tank, and the selected booster configuration.
In a standard installation, the work may include removal of the old hot water system where applicable, positioning the new 315 litre tank, roof mounting the solar collectors, connecting solar flow and return pipework, integrating the booster arrangement, fitting or checking valves, tempering where required, commissioning the controller and pump, and testing operation. Depending on the site, that may also include roof access equipment, electrical work, extended pipe runs, upgraded valves, or changes to the existing plumbing layout.
JR Gas & Water keeps the process practical and clear so customers understand what is standard, what may vary, and what may be needed for a safe and compliant installation.
JR Gas & Water is installation-led, which matters with solar hot water because the success of the job depends heavily on the property, not just the product name. Split solar systems need practical assessment, not guesswork. The right result comes from making sure the system matches the roof, the plumbing layout, the booster arrangement, the tank position, and the household demand.
We work with real homes across Brisbane and the Gold Coast, helping customers choose solar hot water systems that make sense for the property rather than relying on generic brochure claims. With a model like the Envirosun AS315/40 Active Split Solar Hot Water System, that means practical advice, realistic installation planning, and a stronger focus on what will actually work on site.
Installation cost depends on the property and the system layout. A straightforward job with a suitable roof, practical tank position, and workable access is generally simpler than a job involving difficult roof access, long pipe runs, booster changes, electrical work, or other extra works. Final pricing depends on the existing setup and what is required for a safe and compliant installation.
It can be a strong option for homes wanting a split solar hot water system with 315 litre storage and a ground-level tank, especially where keeping the tank off the roof is preferred. The main considerations are roof space, collector position, ground-level tank location, booster arrangement, household demand, and whether a split solar design is the right fit for the property.
A standard installation typically includes the core labour and materials needed to install the ground-level tank, mount the collectors on a suitable roof, and connect the system to the home’s hot water services where conditions allow. That may include tank placement, collector mounting, plumbing connections, valve assessment, booster integration, commissioning, and operational checks. Extra works may still be required depending on the site.
In many cases, yes, but suitability depends on more than just storage size. Whether it can replace the current system depends on the roof, access, plumbing layout, available tank position, boost setup, and whether a split solar system is the right fit for the home overall. Some properties are a good match, while others may suit a different solar or non-solar setup better.
JR Gas & Water installs solar hot water systems across Brisbane and the Gold Coast, and also services Logan, Ipswich, Moreton Bay and Redlands. Availability depends on the job type, roof conditions, access, and site suitability, but we regularly handle solar hot water installation across these areas.
