ADVERTORIAL 45 AWHP – a rising trend for the commercial sector The demand for heating from a renewable energy source is growing daily. With the intention of gas boilers being banned in new build residential buildings from 2025, along with minimum energy e ciency standards raising the bar for Simplified Building Energy Model (SBEM) calculations across both domestic and commercial fronts, energy e cient renewable heat sources are becoming a must for both space heating and domestic hot water. Exi-tite are one of the leading industry figures within both the air conditioning and heat pump markets. Providing renewable heating solutions ranging between 5 to 201 kW capacities from both air to water and water to water configurations. Andrew Robinson, managing director, Exi-tite said: “By being able to provide products aimed at both domestic and commercial sectors allow us to use our full capabilities of inhouse design and application. We are in a position to find the right solution for both consultant, installer and end users. We work on the principle of Design, Supply, Support and this shows more than ever with heat pump projects generating hot water. Not only are we guiding correct application and use, but also finding solutions to maximise e ciency and reduce running costs at every point.” Further to standard domestic AWHP installations, Exi-tite’s inhouse expertise really comes to light with commercial designs. Mark Brown, product specialist, Exi-tite said: “The commercial sector is now looking for alternative solutions away from combined heat and power, natural gas or oil. We are constantly working alongside consultant bodies providing reliable designs for apartment blocks, hotels and leisure facilities. Most of the focus is to produce hot water that is consumed every day, but with heat recovery application we can maximise e ciencies by combining products that produce hot water along with the buildings air conditioning application. “Whilst seasonal e ciencies are high enough to be benefit building energy calculations without heat recovery, it is when both cooling and heating on the same system are active that we really see the benefit. It is possible to achieve a coe cient of performance (COP) of around nine during simultaneous operation. This is where attention to detail during design can really reduce both capital cost and a products life cycle cost.” Ballygawley O ce: 15a Grange Road, Ballygawley, County Tyronne, Northern Ireland, BT70 2LP Belfast o ce: Unit 9 , Building 15, Central Park Mallusk, Newtownabbey, Co Antrim, BT36 4FS Tel: +44 (0) 28 8556 7674 Email: sales@exi-tite.com Web: www.exi-tite.com “The commercial sector is now looking for alternative solutions away from combined heat and power, natural gas or oil for hot water generation.” Recent projects have seen the latest in VRF technology connected to third party close control units. Providing climate control within a data centre, this constant load lent itself to the perfect design for heat recovery. Any heat energy removed from the data centre was utilised in producing potable hot water at 60 o c and for heating third party air handling unit hydronic coils, rather than expelling outside. Making this one of the most cost-e—ective solutions available. Schematic of hot water use generated from heat recovery VRF. CM YK / .ai CMYK / .ai CMYK / .ai acrjournal.uk
