services department in the oldest part of the building, and three Remeha Gas 610-1000 Eco Pro boilers into the book stack boiler room to meet the critical requirement for closely-controlled conditions. Condensing technology is a popular retrofit

solution as it offers the highest efficiencies achievable from boilers whilst minimising greenhouse gas emissions. The Remeha Gas 310/610 range, for instance, offers gross efficiencies in the region of 96% at 50/30°C and NOx emissions as low as 26mg/kWh. As a result, the energy and carbon savings from a boiler upgrade can be considerable: the Carbon Trust puts the figure at around 30%, although this figure can rise still higher depending on the boilers being replaced. An additional benefit of condensing

Not too hot and not too cold, condensing boilers achieve the perfect temperature to protect and conserve the treasures of the National Library of Wales day after day and that’s not to mention the welcome energy and carbon savings. Here James Porter National Sales Manager at Remeha Commercial reports on the energy savings being achieved

t is widely acknowledged firstly, that buildings are large consumers of energy and secondly, that heating and hot water generation alone account for the largest single use of energy. By improving the effectiveness and efficiency of heating in a building, organisations can avoid unnecessarily wasting energy, achieving the dual goals of significant energy and carbon savings combined with a more comfortable and productive working environment for staff and visitors. However, in some buildings there can be a third critical element: maintaining reliable, consistent temperature heating.


NEW SYSTEM FOR WELSH NATIONAL TREASURE The National Library of Wales in Aberystwyth is a case in point. This is the primary research library and archive of Wales, an imposing building housing over 6.5 million books and periodicals in addition to an impressive collection of archives, portraits, maps and photographic images. These valuable, historical archives must be stored in exacting conditions that meet the highest environmental and conservation standards for best practice conservation and protection. So when the boilers began to fail in two of the three plant rooms, the Library moved swiftly to address the reliability and resilience of the heat generation plant,


particularly in the book stack boiler room which serves the critical cells where the priceless collections and artefacts are stored. As part of its wider environmental commitments, the Library was also keen to maximise the opportunity to improve its carbon footprint and reduce energy bills.

MODERNISED HEATING SYSTEM The National Library of Wales is a stately structure, dating back to the early 20th century. As with many of the UK’s high percentage of existing buildings, boilers are at the heart of the heating systems in the Library’s three plant rooms. Due to the nature of the building and the heating systems in place, retrofitting high efficiency replacement condensing boilers presented a practical yet highly effective solution to achieving more reliable heating at the Library. Further, the Library had replaced failing boilers in the third plant room with two Remeha Gas 210 Eco Pro 6-section condensing boilers two years previously and was pleased with the results. Aber Heating Engineers in Aberystwyth,

who had successfully carried out the first installation, were invited to respond to the brief for increased reliability and consistency of space heating. They recommended installing three Remeha Gas 310-500 Eco Pro boilers into the main boiler room that serves the offices and administrative

boilers is that they are as cost-effective as they are effective. This affordability factor makes them a replicable solution for organisations like the Library where two plant rooms could be refurbished simultaneously to improve thermal efficiencies throughout the whole building. Maintaining heating service throughout the project with only minimum disruption during the changeover period to enable uninterrupted visitor access was critical for the Library. The modular configuration of the boilers helped meet the requirement for improved resilience and performance of the heating provision by providing greater reliability and more accurate matching of heat demand. New pipework, new flues and upgraded controls have completed the heating refurbishment. "We are very pleased with the solution that Aber Heating implemented, and the efficient way in which it was done with minimal disruption to our day to day operations and no impact on the thousands of visitors who come to our site,” said David Michael, Director of Corporate Services at the National Library of Wales. “The new Remeha boilers are a major

step forward in improving the resilience of our systems as well as delivering a step change in our environmental performance." This practical, affordable and highly effective installation is set to transform the energy performance of the National Library of Wales, helping it meet its environmental targets, lowering its energy costs, and creating the high environmental standards that will preserve its prized collections for the enjoyment of future generations. It’s the perfect example of retrofit at its best.
