With a generous 315-liter capacity, this hot water system is designed to serve households without compromising on performance. Imagine the convenience of having strong water flow to multiple taps at the same time, even with everyone at home using hot water! That’s precisely what this system delivers with its full mains pressure design.

But what about efficiency? The Dux 315L 315T1 is no slouch in this department either. It offers:

  • Compatibility with off-peak power tariffs, allowing you to curtail electricity costs by heating water during off-peak hours.

  • Dense 50mm foam insulation, minimizing heat loss and reducing reheating for lower running costs.

  • Some of the best energy efficiency ratings in its class, contributing to environmental sustainability.

With these features, you not only get consistent hot water delivery but also save on energy costs and help the environment.

Key Features and Benefits

The 315L 315T1 system’s design clearly showcases Dux’s commitment to energy efficiency. The dense foam insulation minimizes heat loss, leading to less frequent reheating and, consequently, lower running costs. This feature, combined with its compatibility with off-peak power tariffs, ensures you can enjoy warm baths without worrying about astronomical electricity bills.

Moreover, the 315L 315T1 system is designed to cater to the demands of 6 to 8 people, making it a perfect fit for medium to large households.

Installation and Maintenance

The Dux 315L 315T1 system simplifies the installation process with its user-friendly design. It includes flexible water connections on either side of the tank, allowing for versatile installation. However, the system requires a space that accommodates its dimensions of 1765mm in height and 620mm in width. The system is adaptable for both installed indoors and outdoor installation, offering greater flexibility to suit various home layouts.

While the system is engineered for a long service life, regular maintenance such as anode inspection and tank flushing is essential to ensure long-lasting performance and efficiency. With a tank low maintenance approach, you can still achieve the desired results.

Optimizing Tank Performance

Moreover, the water heater employs sturdy Y-class commercial-grade enamel, superior to the standard domestic grade. This coating offers a tougher and more resistant layer, ensuring durability and long-lasting performance.

Tank Size Variations

Recognizing that every household has unique hot water needs, Dux offers a range of options. Therefore, the Proflo range provides a selection of tank sizes, including the 315L capacity.

  • Compact 25 litres

  • Standard 50 litres

  • Medium 80 litres

This caters to different hot water usage needs, accommodating both small and large homes with a reliable hot water heater.

Ensuring Quality with Y Class Commercial Grade Enamel

The 315L 315T1 system, like all Dux products, holds quality as its top priority. It incorporates Y class commercial grade enamel, enhancing its longevity and reliability. This superior enamel is a result of innovative research and development, which have been pivotal in enhancing water heater longevity and reliability.

This feature ensures that your system, with its moisture features durable design, is not only efficient but it’s also built to last. So, you can have peace of mind knowing that you’re investing in a product that values durability as much as performance.

Seamless Integration with Existing Systems

Those considering replacing their water heater will find the seamless integration with existing systems a critical factor. The Dux Proflo 315L water heater shines in this aspect. It includes a larger anode to increase tank life, which could be an advantage when integrating with systems in areas with water quality that affects tank durability.

Moreover, it features a hard-wearing, tough polymer base that resists damage and moisture, suggesting suitability for a variety of installation environments and compatibility with different system requirements. Full flow pressure to all outlets is maintained with the Dux Proflo 315L, so you can be assured that the integration does not compromise water pressure in existing systems.

Replacement of existing electric storage water heaters is made easy with the design of the Dux 315L Proflo water heater. Its installation is facilitated by water connections on both sides of the tank, enabling flexible integration with existing plumbing systems. Moreover, the system offers the versatility of being installed either indoors or outdoors, conforming to different home structures.

Furthermore, a dedicated hard water option ensures compatibility with areas affected by hard water supply, expanding the suitability of the water heater.

JR Gas and Water were fast, efficient and very reliable. They sent a quote quickly that was itemised and comprehensive. I was able to approve the quote online and they were out the next day to fit the new hot water system. As the family have a very ill family member we were all very grateful. We had tried another service just before this company and they were all over the show with lots of comments about "extras", after providing an initial quote. So glad we changed to JR Gas and Water!
