Triton Showers has unveiled ENlight with HeatRepeat, its first electric shower designed to connect to Waste Water Heat Recovery Systems (WWHRS).
The launch coincides with the impending arrival of the Future Homes Standard (FHS) 2025, which marks an important step in the UK’s commitment to reach net zero emissions by 2050. To achieve this, the industry will be required to slash carbon emissions in new housing stock by 75-80%, compared to homes built under the current building regulations.
By capturing otherwise unused energy from the shower wastewater to preheat incoming cold water to the electric shower, ENlight with HeatRepeat can reduce annual energy consumption by up to 51%, slash water usage by 44% and lower carbon emissions by 37%, when compared to a mixer shower connected to a WWHRS, resulting in lower running costs for the end-user[1].
The HeatRepeat technology inside the thermostatic electric shower modulates power based on the incoming water temperature, supplied by the WWHRS. This represents a major advancement in sustainable showering, helping housebuilders to comply with critical compliance metrics such as Target Emission Rate (TER) and Target Primary Energy Rate (TPER).
Beyond energy efficiency, all of Triton’s electric showers support compliance with Part G – Water Efficiency. With an average flow rate of just below 5 l/min, ENlight with HeatRepeat delivers an enhanced shower experience all year-round when connected to a WWHRS. This is especially beneficial in water-stressed areas, where developments must limit water use to below 110 litres per person per day.
When ENlight with HeatRepeat is connected to a WWHRS, the operational carbon emission savings, compared to a mixer shower, can negate its own embodied carbon footprint, including that of the WWHRS, in as little as three months.
ENlight’s design includes a modern OLED display showing both shower temperature and, at the end of the shower, duration, as well as a timer to encourage shorter showers and support behaviour change. It also features a logo that activates as the incoming water temperature rises, leaving users safe in the knowledge that the WWHRS is operating.
In a recent poll of over 4,000 adults, 42% said they have reduced their showers to five minutes to help save the planet and lower household bills.
[1] Calculations are based on 3 people, 1 shower per day, 7.5 minutes, 40°C shower temperature, 12°C incoming cold-water temperature. Savings are based on a 8.7kW ENlight with HeatRepeat electric shower with WWHRS compared to a 8 l/min mixer shower with WWHRS
