2023 TRENDS | SPONSORED Q&A Amy Sedgwick, assistant commercial product manager at ACV Condensing boilers offer buildings greater efficiency in their gas usage for heating Peter Double, managing director at Andel Demand for leak detection in the built environment grows year on year How can the latest Part L revisions help reduce overall costs and increase energy efciency? The latest revisions present an excellent opportunity for both customers and installers alike. Promoting lower temperature rates, the revised regulations ensure boilers are more efcient. Section ADL2 of the regulations states that: All parts of the system, including pipework and emitters, should be sized to allow the space heating system to operate effectively in a manner that meets the heating needs of the building, at maximum ow temperature of 55C or lower. This is closely linked to the science underpinning condensing boiler technology, offering buildings greater efciency in their gas usage for heating and hot water. It also helps a building be ready to transition to low carbon heating in the future. Following the steady increase of capital costs of equipment, and increased market prices, condensing boilers, such as the Heatmaster Evo, offer a compliant system that provides valuable installation and maintenance cost savings. consumption and cost management. Tank-intank is a domestic hot water storage exchanger (DHW), completely immersed in a steel outer tank containing primary water. Manufactured from stainless steel, the wall of the inner tank acts as a heat exchanger between the primary circuit, which is connected to the boiler, and the DHW storage tank. Because of the large surface area for increased heat transfer and high storage temperature of the tank-in-tank system, the volume of water can be signicantly reduced, which in turn, helps to cut costs and direct emissions. It can help to signicantly avoid leakage, sludging, and scale build-up, all of which can have a detrimental effect on boiler efciency. Heating and hot water are available from one single combination unit, and capital costs are much reduced. What are the benets of investing in tank-in-tank as a heat exchange technology? Tank-in-tank technology reduces static heat losses, contributing to overall better energy Which big trends do you see emerging in leak detection in 2023? Sustainability, reducing emissions and increasing the use of renewables will continue to be a hugely signicant trend in 2023 and beyond. Climate change poses a massive challenge to us all and the ambitious UK government target of net zero carbon by 2050 will be a key consideration for all businesses in all industries. Demand for leak detection in the built environment grows year on year. This provides a great opportunity and driver for R&D, innovation and embracing new technologies to continue to deliver the optimum sustainable solutions to customers. Hybrid environmental monitoring systems and water sustainability have become important developments in our leak detection product portfolio. Enhanced, hybrid, multi-function control systems provide customers with a new level of leak detection and environmental monitoring, providing simultaneous and automatic zonal isolation of water, gas and/or oil supply if an alarm is triggered. Protecting natural resources and reducing environmental impact are key to sustainability. Water ow monitoring and motion sensor systems provide sustainable water conservation solutions, protecting natural resources, saving on costs and earning Breeam credits. Digital gas leak detection systems can reduce environmentally damaging refrigerant gas escapes, earn Breeam credit and provide environmental and H&S-compliant solutions for the full range of commercially used gases. Andel is a multi-disciplined company providing a range of sustainable solutions to protect both the built and natural environments. As an environmental company, Andel has taken the initiative to become net zero carbon by 2025. This means becoming more energy efcient, reducing CO2 emissions, eliminating fossil fuels, reducing waste and implementing a forensic approach to measuring the environmental impact of our business. Consequently, sustainability is crucial for our own operations, supply chain and, importantly, for the products and services we offer. 26 November 2022 www.cibsejournal.com CIBSE Nov 22 pp25-28 CPD Q&As Supp.indd 26 21/10/2022 18:38
