Adveco ADplus Instantaneous Commercial Water Heaters

  • A range of three compact floor-standing commercial instantaneous gas-fired condensing water heaters with built-in storage tank
  • Perfect for all water qualities with a 5-year warranty on burner and heat exchangers

Commercial hot water specialist Adveco, announces the Adveco ADplus range of high-power gas-fired condensing water heaters featuring an integrated 120-litre stainless steel water storage tank for instantaneous continuous and on-demand domestic hot water (DHW). The ADplus is available in three variants – 70 kW, 115 kW and 140 kW rated heat output.

“Designed to provide a compact, high capacity and reliable method for delivering instantaneous hot water to a commercial building, ADplus is a tough all-rounder,” said Bill Sinclair, technical director, Adveco. “It is perfect for a wide range of applications – from small instant demands to large-scale continuous DHW needs. With minimal NOX and CO emissions, the ADplus range is an eco-friendly way to serve your building’s DHW system. The rugged construction, supported by Adveco’s in-house warranty engineers, provides real peace of mind for your investment.”

The 115 kW and 140 kW ADplus variants offer two high-quality heat exchangers. Constructed from corrosive-resistant continuous run titanium-stabilised stainless steel, these provide balanced highly efficient operation and built-in redundancy. Heat is provided by the patented Fecralloy premix burner fed by a consistent balanced air/gas ratio at each point of turndown. The high modulation ratio results in high combustion efficiency with ultra-low NOX and CO emissions. A built-in flue back preventer on the combustion circuit prevents possible flue gas recirculation between different exchangers.

The tough, stainless steel 120-litre storage tank is provided with electronic anodic protection and high-quality polyurethane thermal insulation. This enables the ADplus to serve as a semi-storage system, providing always available and instantaneous supply with quick recovery times for continuous provision of DHW. For on-demand needs, ADplus heats what is necessary, with no ignition for smaller withdrawals providing considerable energy savings. When heat is required, the condensing technology provides up to 30% savings in fuel consumption. To reduce acidity build-up caused by the condensing process, the ADplus is equipped with a condensate acidity neutraliser, specifically sized to restore tolerable pH values. With the anti-corrosive construction, ADplus can be used with soft and softened water. For harder water, the recirculating pump regulates the correct water flow according to inlet water hardness helping to prevent the formation of limescale on the heat exchanger surface, ensuring high performance throughout its life cycle.

The extremely compact Adveco ADplus is designed to pass through a standard 65cm wide door for trouble-free installation and offers front access to all inner components for quick, easy maintenance. The integrated cascade controller supports full temperature control and self-check maintenance functions for up to 8 units.

Installing commercial heat pumps – what to look for

Adveco’s FPi32 commercial heat pumps range are not only a renewable source of hot water with low running costs but are one of the easiest to fit when it comes to installing commercial heat pumps.

With the government-led push to replace ageing commercial hot water systems with new, more environmentally friendlier technologies, the demands for heat pump based applications is expected to soar in the coming decade. One of the key concerns raised by the HVAC industry is the availability of trained installers capable of working with heat pumps. While the number of commercial installations may be superseded by domestic sites, their complexity means installers will increasingly be in demand. To prevent costly hold-ups, projects incorporating ASHPs should take into account how difficult or easy installation of commercial heat pumps might be.

The FPi32’s compact monobloc design, with a built-in circulation pump and plate heat exchanger, allows for an easy installation for a multitude of work areas. This includes both indoors and outdoors. They can be installed in small unused spaces, mounted on exterior walls or flat roofs of the site. Installed on flat roofs or mounted onto GRP plant rooms.

An FPi32 installation also requires few ancillaries (strainer, expansion vessel and pressure relief valve) to enable its operation as part of a hot water system. This also helps to keep system purchase costs lower as well.

Another advantage of installing commercial heat pumps, such as these compact FPi32 units, is that less construction work and time is needed to fit them. They can be up and running quicker, providing working flows of hot water sooner than other units currently in the commercial market. They can then efficiently and effectively sustain the necessary working temperature of 50°C required to provide preheat as part of a hybrid all-electric system in new build projects.

Ease of installation goes hand in hand with significantly reduced maintenance costs.

The design of these FPi32 units incorporates effective frost protection, enhancing the option to install outdoors. The FPi32 range is equipped with a 1.5-metre ‘trace heating cable’ as standard, which is there to protect the pipework between the heat pump and the building from frost conditions. This ‘trace heating’ via the mechanical thermostat is always available when the heat pump has power. This guarantees protection against frosty conditions when needed, regardless of whether the heat pump is operating.

This monobloc design simply requires regular cleaning of the coil and water filter in terms of regular maintenance. The internal parts are easily accessible for all maintenance needs. A refrigerant circuit high-pressure gauge is cleverly positioned so that this can be read clearly and easily through the external cover to monitor the pressure and indicate whether a leak may or may not have occurred. Access to the internal parts, in the need of any replacements, can be achieved without long evaluation wait times. For example, if the replacement of non-return valves on sensors and switches is required then the quick replacement time is advantageous, reducing the amount of “down time” on the unit. All of which equates to an extremely work effective and reliable unit for your commercial needs. This demonstrates that, once supplied by Adveco, installing commercial heat pumps is easy and is also a more forward-thinking way for a greener environmental contribution. Reliability and efficiency equal greater sustainability, as well as keeping those costs lower all round.

We would argue that under the right circumstances, installing commercial heat pumps can be a relatively straightforward and successful way to introduce greater sustainability into the hot water system for new build projects. The FPi32 heat pump range represents a win-win, ticking all the boxes for a sensible purchase, offering a simpler, more efficient option for installing commercial heat pumps in a variety of ways. Once fitted, required maintenance is quick and easy, all whilst helping contribute to a project’s green credentials.

Adveco SSB-E Lower Carbon Electric Water Heating

The Adveco SSB-E is a range of tough, stainless steel electric water heaters for commercial DHW applications. Based on the SSB buffer vessel, the SSB-E, through the addition of a specialised single or double-mounting flanges integrates electric immersions becoming a full-fledged electric water heater. SSB-E is available from 200 to 2500 litre capacity variants with up to 84 kW of heating for larger scale commercial hot water demands.

Heating capacity is achieved with up to four primary three to 12 kW immersion heaters. The addition of an immersion of three to 36 kW, installed in the side port is typically used to supply built-in redundancy, but can be used to raise overall heating capacity in high-demand scenarios.

The specialised flanges angle the primary heating elements downward into the vessel ensuring water is heated from the bottom of the tank for optimal efficiency. This energy efficiency is further improved through the addition of 100-125 mm removable insulation.

Alongside the advantages of built-in redundancy, the multiple immersions allow for individual element control. Adveco can supply bespoke control box systems that enable full, individual control of temperature, with easy switching and customisation allowing for varying periods of demand or differential tariff supplies.

Manufactured from high-grade AISI 316L austenitic stainless steel, the Adveco SSB-E range is designed and manufactured to the requirements of the Pressure Equipment Directive (97/23/EC) capable of delivering a maximum working pressure of 6 bar at 85°C. All vessels are tested to the procedure defined in BS EN 12897:2006 and are WRAS certified.

With a wide choice of water capacities, single or double flanges plus a range of immersion sizes and combinations, the Adveco SSB-E provides a bespoke water heater for the most demanding commercial hot water applications.

FUSION Commercial Hybrid Hot Water Systems from Adveco

  • FUSION is a complete range of low carbon hybrid heat pump and electric hot water systems
  • Resilient stainless steel water heating suitable for all UK regions
  • Compact design for new build and refurbishment projects seeking greater sustainability

Commercial hot water specialist Adveco, introduces the FUSION FPH-S range of low carbon, all-electric, packaged hybrid hot water systems. FUSION harnesses Adveco’s FPi32 Air Source Heat Pumps (ASHP), a high-pressure ATSH calorifier with electric immersion, controls, and metering to provide a reliable, high-temperature, sustainable and cost-effective system for new commercial build and refurbishment projects.

FUSION is available in 16 pre-specified variants with 6 or 10 kW preheat and 9 or 12 kW electric top-up, with capacities ranging from 200 to 500 litres all rated at 10 BAR for high-pressure applications. Able to meet a range of continuous capacity hot water demands from 257-377 litres/hour makes FUSION highly adaptable for a wide range of commercial buildings.

The FPi32 ASHP is specified to supply a working flow of 50°C for system preheat throughout the year, even when ambient air temperatures drop as low as -25°C. Electric immersion top-up then raises system temperatures in the calorifier to the necessary 60°C to meet commercial requirements for safe hot water demands. The stainless steel construction of the ATSH also makes it an excellent all-rounder, resistant to soft water corrosion and, with FUSION’s unique low electric immersion heat intensity (6W/cm²), is more resistant to scale build-up in hard water areas.

The physical design, dedicated controls and integrated metering ensure the ASHP preheat, and immersion work seamlessly to deliver the highest operational efficiencies. This enables FUSION to make the greatest gains possible from the heat pump, even when ambient temperature and system demands fluctuate. These gains offset much of the direct electrical energy usually required, delivering 53% carbon emissions saving and helping control the operational costs of providing business-critical hot water.

“For organisations with small to medium basin and sink led hot water demands and a desire to embrace a more sustainable business model, the FUSION FPH-S range provides a single, easy to accommodate, highly effective response,” says Bill Sinclair, technical director, Adveco. “By choosing one of these packaged hybrid water systems you gain optimum efficiencies, lower your carbon emissions and can be assured building regulations are being met for your commercial project.”

Calorifiers and Hot Water Storage in Corrosive Water Conditions

For many companies, the assured availability of hot water is a business-critical issue, but one that can quickly become costly for those operating in the southwest and northwest of the UK, the Welsh coast and throughout Scotland. With a low pH, low total dissolved solids (TDS) and negligible buffering capacity, these naturally soft water areas prove highly corrosive to glass-lined vessels used as calorifiers and hot water storage.

Glass is, given the right conditions, generally resistant to attack from most chemicals and corrosive materials and easier to clean, making it a popular choice for lining steel vessels used in hot water systems. But corrosion is a complex phenomenon, and in naturally soft water conditions, despite the use of sacrificial anodes, glass-lined vessels can rapidly succumb to critical corrosive damage.

Pressure to Perform

In addition, the taller the structure, the greater the pressure requirements on the system, particularly since a common design choice is to locate the plant room in the basement. In order to meet, even small demands with a consistent, strong flow of hot water systems inevitably are oversized, adopting a larger, often bespoke tank.

This immediately exacerbates the existing threat, as oversizing, or the failure to correctly balance water flow also contributes to system corrosion. Oversizing of the pumps leads to high-velocity hot water circulating through the system and suspended solids in the water are driven against the metal leading to erosional corrosion. This process helps accelerate the soft water corrosion at points where water changes direction, such as when passing into or through tanks.

Glass-lined water vessels used as calorifiers and hot water storage under these conditions can potentially fail due to corrosion in a matter of just months – even with the use of sacrificial anodes. For these reasons, manufacturers will reduce or have even ceased to offer warranties on glass-lined products installed in these soft water regions. As a result, their specification into projects in these regions really can be a false economy.

Change to Resistant

Far more resistant to these water-side assaults are stainless steel vessels. Although there is a higher upfront cost, this would be easily offset by the relative longevity of the appliance. However, projects with smaller, yet higher pressure hot water demands, will still face the issue of oversizing. This further extends capital costs, of products, installation and the need for greater plant room space. As a result, project costs can become prohibitive for stainless steel, resulting in the specifying of the less expensive glass-lined alternatives gambling that they will prove resistant enough in the mid-long term.

Adveco addresses these concerns with its ATSx range of compact stainless steel, high-pressure hot water tanks. Specifically designed to serve as buffer vessels (ATSB) and indirect hot water calorifiers suitable for use with lower capacity, high-pressure commercial applications in soft water areas. The ATSx range provides specifiers and contractors with a wide choice of calorifiers and hot water storage vessels all rated to 10 bar as standard, which are by far the most efficient and cost-effective choice for businesses with smaller system demands.

Another advantage provided by the indirect water heaters in this range (ATSI, ATST, ATSH & ATSR) is that due to the transferral of heat through the walls of the heat exchanger element the two fluids do not mix. This allows for more options in terms of the external heat supply and introduces a range of renewable technologies that use other fluids for heat transfer including solar thermal collectors and Air Source Heat Pumps. The twin coil ATSR has been specifically designed for these lower-temperature renewable applications. These calorifiers are also relatively simple to install, since there is no burner, there is no need for a gas supply to be directly connected to the appliance and the is no requirement for a flue.

As with any hot water application, understanding the relationship between storage and recovery, and correct sizing is extremely important for efficient and cost-effective operation. Integrating a stainless steel calorifier within a hot water system gives you a number of design options, with a large efficient boiler a calorifier can be smaller avoiding unnecessary capital and ongoing operational expenditure. At 200 to 1000 litres the ATSx range provides a compact, tough resolution for lower demands applications in those soft water areas. If your project has pressure requirements greater than six bar, then the ATSx vessels are by far the most efficient and cost-effective choice for your project.

If the boiler is smaller, or demands for hot water are greater, then going too small means the storage could prove inadequate and the system will not achieve its operational requirements. For projects with larger demands or requiring greater customisation Adveco can support the project with the SSB, SSI and SST ranges of bespoke stainless steel calorifiers and hot water storage vessels.

Green Heat Network Fund Set to Open to Applicants in 2022

The Government has released initial details of its Green Heat Network Fund (GHNF) which will open to applicants in England from April 2022 and is anticipated to run until 2025, incentivising new and existing heat networks to move away from high-carbon sources.

With decarbonising heat set as a key part of the Government’s heat and buildings strategy, the new fund is intended to replace the existing Heat Networks Investment Project (HNIP) that has been available since 2018.

The £270 million GHNF will only support low-carbon technologies such as heat pumps, solar and heat recovery in the rollout of the next generation of heat networks. The intent is to help cut carbon emissions from domestic and commercial building heating – which accounts for 21% of the UK total – making it one of the country’s largest carbon emissions sources.

Heat networks, supplying heat to buildings from a central source, are intended to provide large-scale renewable and recovered heat. The GHNF will only support applications if they include low-carbon heat-generating technologies, such as heat pumps and waste heat with the aim of incentivising and kick-starting the demand for heat pumps as part of a wider mix of low-carbon heating options.

Although heat networks currently meet approximately 2% of the overall UK demand for heating, the independent Committee on Climate Change (CCC) has estimated that, with continued support, they could provide 18% by 2050.

The Green Heat Network Fund is expected to fund the delivery of an estimated 10.3Mt of total carbon savings by 2050.

The responses to the GHNF can be read here.

2021 – Adapting to new technologies and approaches

The UK’s construction industry is familiar with adapting to new technologies and approaches to provide the latest and most efficient responses for creating better buildings.  2020, however, was unprecedented, but what does this mean for 2021? Looking forward, key trends within the industry include Covid-19 care, greener response sand efficient use of property space.

Coronavirus has attacked every corner of the UK, impacting the majority of businesses and therefore the wider economy. Despite vaccines, Covid-19 is now something we all must learn to live with, it has accelerated change and requires a re-evaluation of how buildings are conceived and used. As a specialist in the provision of commercial heating and especially hot water, Adveco is well versed in the design of systems to support the maintenance of hygiene within their buildings, critical for the ongoing prevention of the spread of Covid-19. There has never been a greater need for access to wash stations. Scientists have proven washing hand in warm, soapy waters for more than 20 seconds can reduce the spread of Coronavirus more efficiently than hand sanitisers. Additionally, hot water (at a minimum of 60°C) needs to be readily available for cleansing of materials and surfaces to prevent the spread further. With these requirements comes a need for more efficient systems capable of meeting these increased demands to be incorporated into commercial buildings. With the demands of maintaining a safe two-metre distance, space has become even more valuable. The hospitality sector is already struggling with the challenge of balancing revenue losses from reduced covers and are looking at how to create alfresco spaces to adapt to this new normal. Packaged plant rooms offer companies a means to use minimal space whilst still maximising efficient systems, freeing up valuable internal spaces or making use of dead spaces which are not customer friendly. This is also a fast, relatively low impact method for refurbishing hot water systems.

Despite all the chaos of Covid-19, it also brought into razor-sharp focus the effects of pollution. This was all too obvious when the world stopped for a moment and the effects of pollution decreased and allowed the environment to thrive. It proved to be a rallying cry for decarbonisation in 2020 and will continue to create headlines throughout 2021 and beyond. It remains a core focus for the construction and HVAC industry that will continue to strongly push for more wide-reaching frameworks to deliver eco-friendly technology and buildings to meet the challenging goal of achieving Net Zero by 2050.

Through exclusive technical partnerships and our in-house design function, Adveco can quickly adapt to these changing needs and help innovate products and systems to directly address the evolving challenges of decarbonising commercial buildings. We recognise that there is no single technology that delivers the entire answer, but there is no doubt Air Source Heat Pumps (ASHP) will play an important part, as will new green gas technologies towards the end of the decade.  This makes hybrid system approaches all the more valid for supporting the near-term transition of commercial organisations to a more sustainable track that reduces their building emissions and operational costs.
