Electric Commercial Water Heating From Adveco


T


he 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 3-12 kW immersion heaters. The addition of an immersion of 3-36 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 larger scale commercial hot water applications. For lower capacity (200 to 1000 litres) high pressure (10 bar) projects Adveco’s ATSx range of compact stainless steel hot water tanks all feature multiple connection points for the addition of electric immersions making the vessels suitable for use as single, or dual coil calorifiers as required for DHW applications in commercial buildings. The ATSH indirect water heater feature a single internal high capacity fixed heating coil at low level for use with a high powered indirect heat source and electric immersions above. The ATSR vessel in particular features two internal fixed heating coils, at low and high level, with an increased surface area specially designed for use with renewable heat sources. The multiple connection points for direct electric heating support peak demands and provide system redundancy, especially during cold, dark winter months. For hard water areas where scale build-up can prove problematic, Adveco can specify the 9kW or


12kW electric immersions with a uniquely low 6W/cm2 heat intensity. Without detrimental effect to the demands for hot water, this slows the potential for scale build-up. The tough AISI 316Ti and 316L stainless steel construction also makes the ATSx range a resilient, corrosion-resistant option for projects where water is naturally soft.

Energy Assets Boosts its AMR Platform for Universal Coverage


E


nergy Assets is expanding its electricity meter data collection capabilities to near universal coverage across Britain’s industrial and commercial markets. The company, a leader in energy metering and analytics, has broadened the reach of its


automated meter reading (AMR) service to cover around 99% of all power meters serving private and public sector organisations. This enhanced AMR capability widens the potential scope of the company’s Data Collection and Data Aggregation (DCDA) services to a growing customer base of energy suppliers, brokers and end users. “I doubt there’s ever been a time when energy consumption data has been so critical for companies


as they look for ways to mitigate the impact of escalating costs,” said David Sing, Energy Assets Group Managing Director (Assets). “So, I’m delighted we’re now able to help more end users and their suppliers collect consumption


data automatically and easily, and to extract the information they need to understand better how they’re using energy and where they can make efficiencies.” The expansion of the company’s AMR coverage augments the end-to-end suite of services developed


by Energy Assets to help organisations sharpen their focus on power consumption, whether through advanced metering, data collection or sophisticated reporting and analytics tools. The increased scope means suppliers will benefit from more efficient reads of mixed meter portfolios. “We’re entering an era in


which data will increasingly become the measure of sustainability for commercial and industrial energy users, particularly with the move to the Market-wide Half-Hourly settlement (MWHH) by 2025.” said David Sing. “For business users,


data will not only be key for carbon reporting and ESOS strategies, it’ll also be critical in driving energy efficiencies and opening up opportunities for customised ‘time-of-use’ tariffs. Now’s the time to make data work for you.”

Study shows importance of humidity alongside ventilation


A


recently published study from the University of Oregon has demonstrated the effectiveness of ventilation, filtration and humidity to minimise airborne SARS-CoV-2 viral particles. For three days


each, eleven COVID positive subjects undertook different activities in an environmentally controlled chamber. Levels of ventilation, air filtration and humidity were varied across the study period and the quantity of viral particles monitored in the air and on surfaces. The researchers found that increasing ventilation and filtration significantly reduced the amount of SARS-CoV-2 viral particles in both the air and on surfaces. When humidity was increased, viral particles in the air reduced by half and caused an increase in viral particles on surfaces. Tony Fleming, Head of Sales Cluster Northern Europe at Condair, commented, “This research is really significant as it’s the first study to


demonstrate how air treatment strategies can impact the airborne transmission of COVID in a physical setting, rather than by computer modelling. The results justify the emphasis placed on increased ventilation by the authorities but it also highlights the need to humidify our public buildings. Official advice on humidification has been greatly lacking. The recently updated Part F of Building Regs totally ignored the issue of low indoor humidity and the health benefits of maintaining a mid-range 40-60%RH. “The fact that increasing room humidity in this study resulted in 50% less airborne viral particles


and increased levels on surfaces, shows that humidity plays a major role in determining how long viral particles remain airborne. Dry air causes an increased “float time” for the aerosols we all release. As airborne transmission has been shown to be the major COVID transmission route, humidification of places like hospitals, offices and schools is a practical mitigation strategy to reduce the risk of airborne cross infection.” Tony Fleming concluded. Dr Van Den Wymelenberg, architecture professor and director of the Institute for Health in the Built Environment at the University of Oregon, was the senior author of this new study. He commented, “Intentional humidification is not often incorporated into indoor spaces due to cost or maintenance concerns, but should be considered, since it can support increased viral particle deposition, as shown in this study, as well as support our bodies’ natural defence mechanisms by reducing the drying of our mucus membranes.” The study also concluded that the amount of viral particles in the air was not very different at 4ft


(1.2m) from the infected subjects to 11ft (3.3m) from the subjects. This casts some doubt on the practical effectiveness of one or two-metre rules implemented under social distancing guidelines. The Condair Group is the world’s leading specialist in humidity control and evaporative cooling,

Gilberts applies sustainability to value engineering


win:win situation is available to building services designers and contractors with revisions to Gilberts’ ground-breaking MFS


hybrid ventilation unit. As part of the company’s commitment to continuous evolution to offer better, greener solutions, the stand-alone ventilation, heating and cooling system has been value engineered. Not only is the new version cheaper whilst retaining its quality and performance, it uses less steel. It also makes it lighter in weight, potentially reducing transport costs structural loadings (and potentially build costs).These make a positive contribution towards its embodied carbon. Being lighter in weight, the new MFS further requires less labour effort to install. These benefits compliment those eco-advantages already within the MFS concept. Gilberts’ MFS in


effect works as a natural ventilation unit, only using its integral low energy fan to supplement airflow as conditions demand. MFS can be configured to run on 100% fresh air, using a LPHW coil to temper the air to provide Covid compliant ventilation without compromising the internal temperature. Integrated into the heating system- including heat pumps- Gilberts’ MFS can utilise the warmth generated from LPHW systems to warm or cool the internal space as needed without the need for radiators and all associated ancillary capital costs. As a solus ventilation unit, MFS costs as little as £5/room/year(1) to operate. Using it as the means of room heating adds just £2.19/room/year(1). MFS has already been proven to help achieve BREEAM Excellent(2), contributing points towards


Energy and Health & Wellbeing. Installed through the external façade or window, Gilberts’ MFS mixes internal and external air to ventilate the internal space. A mixing damper within modulates airflow to allow the new, fresh air to mix with the warm exhaust air, thus extracting its heat without the need for an exchanger. The integrated low energy fan energises to blend the internal air, ensuring an even distribution of airflow without stratification. It gives control over temperature and CO2 levels within and maintenance of a comfortable internal environment for occupants. Says Ian Rogers, Gilberts’ Sales Director, “With the drive towards reducing our carbon footprint,


MFS gives everyone involved in the building services supply chain, including the end customer/building occupants a benefit. It is a genuine ‘win:win’, whether new build, refurbishment, re-purposing. The new MFS typifies Gilberts’ place as the UK’s leading independent air movement specialist, engineering from concept quality products that meet or anticipate market forces and deliver for the environmental agenda.” Full details of the MFS system can be found on Gilberts’ website where BIM calculations and CAD drawings are also available for download.
