Summary
Adveco's FUSION TW hybrid electric water heating system wins commercial product of the year at the 2025 Energy Saving Awards. Greg Brushett, Sales Director, Adveco Said, “Winning at the 2025 Energy Saving Awards is another tremendous accolade for FUSION TW and reflects all the hard work the teams here at Adveco have invested in bringing a ground-breaking product to market. FUSION continues to change the way low-carbon water heating can be specified in commercial buildings."
FUSION TW, a packaged electric water heating system for commercial projects, has been named winner of the Commercial Heating Product of the Year category at the 2025 Energy Saving Awards. The Energy Saving Awards celebrate the very best professionals, products and projects across the Plumbing, HVAC and Energy Management sectors, acknowledging the important work that has been achieved by manufacturers, installers, contractors, suppliers and organisations to reduce carbon emissions and become more energy efficient.
FUSION was conceived by the team at Adveco as a means of harnessing a hybrid approach to reduce energy demands and deliver a low-carbon resolution for new build and gas-to-electric transition projects. It achieves this whilst avoiding costly oversizing and the need for bespoke system design, which raises costs and the feasibility of decarbonisation strategies.
The new FUSION TW/TWplus reimagines FUSION with the integration of the ADV-W series of air source heat pumps and brand new control to offset this primary heating supplied by an ARDENT electrical boiler. Both the heat pump and boiler are connected to a 750-litre ATST twin-coil cylinder to create an indirect water heater.
Greg Brushett, Sales Director, Adveco, said, “Winning at the 2025 Energy Saving Awards is another tremendous accolade for FUSION TW and reflects all the hard work the teams here at Adveco have invested in bringing a ground-breaking product to market. FUSION continues to change the way low-carbon water heating can be specified in commercial buildings. It allows for highly optimised applications which can be provided off-the-shelf in pre-sized, ready-to-go systems with a smaller footprint, that are easier to install, more efficient and cost-effective to purchase and operate. “
FUSION excels in the deployment of smart controls, maximising pre-heat input from the ADV-W series of heat pumps, capable of contributing as much as 70% of system heat requirements, and balancing this with the primary input of the ARDENT electric boiler so that the two heat sources blend harmoniously, offsetting as much direct electric demand as possible. If this is not managed correctly by the controls, the two heat sources would act in contention, countering system efficiency and wasting energy.
Specification allows for the selection of a system based on nominal power output (kW), storage capacity (litres), continuous flow (litres/hour), instantaneous draw off capacity (litres) and peak draw off (litres). This offers 25 base variants of the TW, each supporting the addition of an incorporated backup electric immersion (TWplus).
When comparing TW and TWplus systems to equivalent direct electric DHW systems, offset energy use delivers carbon emission savings starting at 20.53% climbing to 47.75%. Across the entire range, we can see an average of 36.3% savings versus other direct electric systems.
When calculating the carbon emissions savings for FUSION TW, they become more notable when compared to gas-fired systems. Starting at 51.11% and climbing to as much as 67.86%. Across the entire range, we can see an average of 60.8% savings versus the latest generation of gas water heater systems.
“Hybrid systems have the potential to be complex and come with greater capital expense, especially at a commercial scale,” Greg observes. “Adveco’s award-winning FUSION TW with ADV-W ASHP counters this with a far more compact monobloc form factor to lower entry costs for ASHP-based water heating and drive the uptake of sustainable systems in the UK.”
