Adveco reimagines FUSION for lower-carbon water heating

Commercial hot water specialist Adveco reimagines its award-winning low-carbon FUSION packaged electric water heater system with new models that take advantage of the more powerful ADV-W air source heat pump (ASHP), enhanced controls, and a greater choice of backup immersion heaters.

• Cuts DHW carbon emissions by up to 68% compared to equivalent gas systems

• Increased choice of system preheat and greater backup options

• Enhanced system controls 

For commercial organisations with sink-led hot water demands, taller buildings with basement plant rooms or operations that rely on 24/7 hot water supply Adveco FUSION TW provides the most comprehensive response available today.

The all-new FUSION TW and TWplus packages take the existing sealed primary loop combination of ARDENT electric boiler and ATST twin-coil cylinder and now add a range of monobloc ASHP alternatives with the new FUSION Control Box for greater carbon reduction and increased system output for more demanding hot water applications.

FUSION TW and TWplus gain a wider choice of compact, pre-charged R32 ASHPs which are easy and safer to install, especially when space is limited, and operate quietly. System preheat is generated by either 10 – 16 kW single-phase ADVS-W ASHP, or 16-30 kW ADV-W in three-phase capacity.  With an A+++ ERP energy rating, and high SCOP with water outlet temperature 60° the ADV-W will maintain a consistent supply of hot water at up to 55° to pre-heat the FUSION system.

The TW-plus plus variants include either a 6 or 12 kW electric backup immersion for no single point of failure for assured delivery of hot water without downtime.

Balancing these system elements is a critical function of the design, and smart controls ensure contribution from the ASHP is maximised to deliver a working flow of 50-55°C at an ambient operating temperature of 2°C, setting a realistic benchmark for operating conditions in the UK. FUSION’s new enhanced controls not only optimise the mixture of pre-heat from the heat pump, but they also manage the elements within the electric boiler and backup immersions. This ensures the electric boiler is not required to work as hard to raise flow temperatures to the 65°C demanded by commercial applications, reducing maintenance demands and improving the longevity of the boiler.

Adveco has released new single- and three-phase control panels supporting both ADVS-W and ADV-W variant ASHP. Time control clock controls are built-in, as is thermal disinfection.  When connected to the BMS, disinfection and high-temperature pasteurisation functions can also be monitored when active, and a fault relay can be instigated. The new panels support connections for the LLH pump, lighting, socket, heater bar, secondary return pump and destratification pump output. With the inclusion of a GSM module, fault notifications can be enabled from the BMS or via text. The new controls also provide the option to prevent immersion activation when ASHP goes into fault to limit current.

With storage capacities ranging from 300 to 750 litres provided by the corrosion-resistant, stainless steel, high-pressure indirect cylinder, nominal power output ranges from 19 kW to 52 kW in FUSION TW.

FUSION TW variants will support instantaneous draw off from 130 to 315 litres/hour and continuous flow rates starting at 323 litres and climbing to 883 litres per hour. With the ASHP able to contribute up to 70% of system heat, FUSION systems will offset some of the direct electric energy demands, meaning it can help control daily energy costs as well as extend the life of the electric boiler.  Carbon emissions compared to electric-only systems are cut by as much as 48% and up to 68% when compared to gas-fired equivalents.

Greg Brushett, sales director, Adveco, says: “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 provides assured operation, fully countering limescale in hard water areas, whilst tough enough to prevent the corrosive action of soft water. And with new system enhancements, support for single and three-phase specifications, plus greater power output for even larger projects, FUSION offers the means to realistically meet net zero strategies today. Adveco is also able to support bespoke commercial projects applying FUSION’s hybrid system
