Domestic Energy Saving Product of the Year


Winner: Daikin for Multi+


The Multi+ is an all-in-one domestic system that provides hot water, heating and cooling from a single compact unit. It is specifically designed for small to mid-sized households, replacing multiple inefficient appliances with one integrated, energy- saving solution. The Multi+ achieves its


efficiency through a combination of advanced technologies and smart operation. Seasonal performance ratings are among the best in the market: A+++ for cooling, A++ for heating, and A for hot water. Its high-efficiency swing compressor and optimised refrigerant cycle convert 1kW of electricity into 3-4kW of usable heating or cooling output, cutting energy consumption by up to 75% compared with electric immersion heaters. The system’s advanced heat exchanger and variable-speed compressor continuously adjust output to match household demand, minimising energy waste while maintaining consistent comfort. Key energy-saving features include scheduled hot water production at off-peak times,


Judge’s comment: “The system brings together hot water, heating and cooling in one compact outdoor unit, supported by a choice of wall-hung or floor-standing hot water tanks.”


shared energy supply across up to four indoor units, and future- ready integration with solar PV to harness self-generated renewable power. In real-world testing at Blue Water, a home in Thatcham, 95.9kWh of input electricity produced 468.8kWh of thermal output, reducing daily running costs to just £1-£1.50. Compared with alternatives,


Multi+ offers clear advantages: it achieves up to a 4:1 energy conversion, far surpassing electric immersion heaters, which operate at 1:1; it eliminates


fossil fuel use entirely, unlike gas or oil boilers that produce carbon emissions and expose households to fuel price volatility; and it integrates heating, cooling, and hot water in a single system, whereas other compact solutions typically provide only two of these functions. With intuitive control via


the Daikin Onecta app, home- owners can remotely monitor and optimise energy use, ensuring heating, cooling, and hot water are activated only when needed.


Commercial Heating Product of the Year


Winner: Adveco for the Fusion TW/TWplus packaged electric water heater


Fusion from Adveco stands out as an intelligent hybrid approach to commercial water heating. Unlike conventional systems, Fusion combines a high-efficiency air source heat pump with an electric boiler and optional solar thermal preheat, all managed through smart controls.


Fusion is a packaged electric


water heating system designed for commercial projects, offering a low-carbon solution for both new build and gas-to-electric transition applications. It avoids costly oversizing and bespoke design while meeting peak water heating requirements efficiently. The Fusion TW/TWplus


integrates Adveco’s ADV-W series air source heat pumps with an Ardent electric boiler, connected to a 750-litre ATST twin-coil cylinder to form an indirect water heater. The ADV-W heat pump maintains high seasonal efficiency while delivering consistent preheat up to 55°C, enabling the hybrid system to meet commercial water heating demands, including the +65°C anti-Legionella requirement, without excessive energy use. Its all-DC inverter, microchannel


refrigerant heatsink, and R32 refrigerant minimise energy consumption while maximising safety and performance. Smart controls optimise heat pump preheat and balance the electric boiler and immersion backup, adjusting output according to ambient conditions from -20°C to +43°C. This ensures maximum efficiency, reducing both energy costs and carbon emissions.


Fusion’s pre-sized variants cover a wide range of capacities,


allowing specifiers to select the right system without bespoke engineering. Compared with equivalent direct electric systems, Fusion delivers average carbon savings of 36%, while reductions versus gas-fired systems average 61%. With the option to incorporate solar thermal preheat, it can further cut operational energy and emissions, offering a compact, all-electric, low-carbon water heating solution ideal for commercial buildings.


SmarterDM’s wireless intelligent energy management system, using networked Smarter Panel Heaters custom-modified from Dimplex’s PLXE series, is designed to save energy in high-occupancy environments such as hotels. Paired with environmental sensors that monitor room occupancy, temperature and humidity, the system automatically reduces heating in unoccupied rooms and can override set points after a grace period, maintaining comfort while avoiding unnecessary energy use. The system operates via a proprietary LoRa mesh network, routing data to a central hub and enabling long-range wireless communication. Smarter Panel Heaters can receive in-situ firmware upgrades, eliminating


the need for costly replacements, minimising installation disruption and accelerating payback from energy savings. Cloud-based control provides


real-time reporting of occupancy and heater usage, flags faults and enables remote monitoring of multiple rooms simultaneously. With battery-powered sensors and no need for secondary controllers, the system offers a non-intrusive, scalable, data-driven approach that reduces energy use while improving operational oversight in large-scale accommodation or commercial properties. Independently verified energy savings exceed 40%, and the system has been successfully implemented across Travelodge’s UK estate of over 40,000 bedrooms.


Judge’s comment: “Fusion stood out for its hybrid design, maximising heat pump preheat to deliver major energy and carbon savings.”


Highly Commended: Triton Showers for ENlight with HeatRepeat


ENlight with HeatRepeat is Triton’s first electric shower designed specifically to pair with a Waste Water Heat Recovery System (WWHRS), offering a high-impact solution for reducing hot water energy demand in homes built to the Future Homes Standard 2025. As showers account for around half of domestic hot water consumption, integrating an on-demand electric shower with heat recovery tackles one of the biggest remaining energy loads in low-carbon homes. Electric showers are


inherently efficient, heating water only when required, but ENlight with HeatRepeat amplifies these savings by reclaiming thermal energy normally lost down the drain. The WWHRS pre-warms incoming cold mains water, meaning the shower requires far less electricity to reach the set temperature. This combination significantly reduces both peak demand and overall consumption. Performance data shows impressive results: annual energy use can be cut by up to 51%, water consumption by 44% and carbon emissions by 37% when compared with an 8-litre per minute mixer


shower connected to a WWHRS. Against a standard mixer shower without heat recovery, energy savings rise to 79%, with carbon savings of 72%. ENlight with HeatRepeat also achieves an 18°C inlet temperature rise at just 4.0kW, maintaining comfortable flow while minimising power input. By pairing efficient electric


heating with recovered waste heat, the system delivers year- round consistency, substantial reductions in hot water energy demand, and a practical pathway to net-zero-ready homes.


Highly Commended: SmarterDM by Dimplex for Smarter Panel Heaters
