Water Saving Domestic Product of the year


Winner: Mira Showers for the Advance Heatloop


Specifically engineered to work in conjunction with waste water heat recovery systems (WWHRS), the Advance Heatloop is an innovative shower system designed to improve water and energy efficiency. Unlike conventional showers that typically consume around 13 litres of water per minute, the Heatloop operates at a flow rate of just 5.0 litres per minute when paired with the Recoup WWHRS. This reduction is crucial, as even a five-minute shower in a traditional system can consume between 75 and 90 litres, accounting for approximately 40% of a person’s daily water needs. By minimising water consumption, the Heatloop not only conserves a vital resource but also helps users save on their utility bills.


Taking the cold feed from


the mains supply and heating water instantaneously, the Advance Heatloop reduces hot water demand from the main hot water system. Providing hot water instantly not only ensures


Highly Commended: Triton Showers for the ENVi electric shower range


The ENVi electric shower range allows users to monitor their water and energy consumption in real time, promoting mindful usage. With a flow rate significantly lower than conventional showers, it saves over 40 litres of water per use, which can lead to big savings if adopted widely – potentially over 673 million litres annually across the UK.


ENVi encourages users to reduce shower time by just one minute, translating into substantial reductions in both water usage and carbon emissions – equivalent to removing nearly 4,000 cars from the roads. Its A-rated efficiency ensures it heats water only when needed.


Judge’s comment: “A real first, producing both energy and water saving outcomes.”


a reliable and efficient demand- reducing solution, it also means users won’t waste water waiting for the shower to reach their required temperature. Used in conjunction with


the Recoup Waste Water Heat Recovery System (WWHRS), the Heatloop excels in conserving both water and energy. This synergy allows the system to recycle as much heat as possible, reducing the energy required to operate the shower. When fully integrated, users can save up to


40% on showering energy. For an average family of three, each member showering for eight minutes six times a week, this translates to annual savings of between £94 and £135. The Advance Heatloop boasts an impressive energy efficiency class of A. It heats water only when necessary. As the first and only electric shower in the UK designed to work alongside WWHRS, the Mira Advance Heatloop provides a safe and consistent showering experience.


Water Saving Commercial Product of the Year


Winner: Prefect Controls for the SMART Tank


The standout feature of SMART Tank is its advanced monitoring and control capability, which enables precise detection and management of water usage. As a pre-wired, pre-plumbed,


centrally controlled hot water cylinder, featuring factory- fitted on-board controls that enhance efficiency and monitoring, its advanced design includes temperature sensors throughout the tank, ensuring precise control of incoming and outgoing water temperatures. This tight temperature regulation prevents over- and under-heating, optimising energy consumption. Temperature sensors are positioned across the tank to monitor and measure incoming cold and outgoing hot water. In-built pockets optimally aligned with the elements contain probes that read internal water temperature around the upper and lower elements at the tank’s core.


Judge’s


comment: “The SMART Tank is a stellar example of how technology can be harnessed to promote


sustainability and water efficiency.”


Meters on the incoming cold-


water supply/outgoing balanced cold water feed, measure the volume of water coming into the cylinder and that going to the balanced cold water supply. Irus calculates the volume supplying the hot water outlets. If installed on a system with secondary return, there is a sensor to read this water temperature. A flow sensor detects water passing through the tundish. This could be a sign of pressure issues.


The control unit has an input


for leak sensors. Any escape of water is detected, and location/ intensity reported back to Irus. Alerts are then sent to appropriate personnel. Finally, the control unit has humidity, sound pressure and light level sensors. They record environmental conditions within the tank cupboard, report on excessive levels, and log tank cupboard interactions. The system’s centralised control allows for remote management.


The Tempomatic Dual Control WC flush valve, with automatic and manual activation modes, offers significant energy efficiency. The automatic mode, powered by mains electricity or batteries, uses a bi-stable solenoid valve, minimising energy consumption and extending battery life to 350,000 cycles (three to six years). By eliminating the need for a


cistern, the Tempomatic system reduces the risk of leaks, which are a major source of water waste in buildings. Traditional cisterns


can waste significant amounts of water, while this valve connects directly to the water supply, ensuring efficient rinses without refill downtime.


The automatic flush volume


adapts based on user presence, with options for 3 or 6 litres – far less than the typical 9 litre flush. This intelligent design minimises waste and enhances cost-effectiveness. The flush valve is compatible with sea water, rain water and grey water, offering a sustainable solution for facilities teams.


Judge’s comment: “Great water saving product which will reap benefits where high usage is expected and reduce water consumption.”


Judge’s comment: “A superb entry looking at every aspect of the product and tackling the biggest household water user.”


The appliance is also Triton’s first ClimatePartner certified product, demonstrating the business’s commitment to taking responsibility for its carbon emissions. Through this partnership, Triton has calculated the carbon footprint of the entire lifecycle of the ENVi shower and is investing in climate projects to fully compensate for these emissions.


Highly Commended: Hansgrohe for Tecturis basin mixer taps


Tecturis taps incorporate two innovative technologies: EcoSmart+ and CoolStart. EcoSmart+ reduces water flow to a maximum of 4 litres per minute, achieving up to 60% less water consumption compared to conventional taps. An integrated aerator enriches the water with air, ensuring a satisfying shower experience despite the reduced flow. CoolStart technology enhances energy efficiency by ensuring hot water flows only when needed. This intuitive


Judge’s comment: “Interesting concept and the quoted figures look impressive.”


design can reduce a four-person household’s CO2 emissions by 23kg annually. Together, these features can


save households up to 29,200 litres of water and 508 kWh of energy each year, translating to potential savings of £122 on bills.


Highly commended: Delabie UK for the Tempomatic Dual Control WC Flush
