BUILDING MAINTENANCE CLEANER, GREENER HEATING With unparalleled high performance and easier maintenance,
condensing boilers reliably achieve the energy-efficient heating required for the smooth running of a building, writes James Porter, Sales Director at Remeha.
A building without heating or hot water is, quite simply, uninhabitable. But this critical service is also responsible for around half the total energy use of a building. As environmental legislation and targets tighten, maximising the efficiency of the heating system is central to reducing a building’s environmental impact and cutting operating costs.
“SIMPLY UPGRADING ANY INEFFICIENT EXISTING BOILERS
CAN REDUCE ENERGY USE BY 30%.”
Boilers are the popular, tried-and- tested technology at the heart of the heating system in many UK buildings. However one boiler is not always as efficient as the next. Even with good maintenance programmes, 10-to-15- year-old boilers will, at best, operate at a maximum gross efficiency of 70%. Compare this with modern condensing boilers, the most efficient of all boiler technologies, which offer exceptional efficiencies of around 98% gross and the figures speak for themselves.
Simply upgrading any inefficient existing boilers to high efficiency condensing boilers and adding the appropriate control can reduce energy use by 30%, according to the Carbon Trust. The business case for recommending a boiler replacement is strong as the relatively low initial investment delivers rapid financial payback. Then there’s the prospect of future savings in running and maintenance costs. This is an

important consideration given that operating costs account for 80% of a building’s total lifetime costs.
There is a growing connection between sustainable buildings and the increased wellbeing and productivity of its occupants. Condensing boilers provide an environmentally as well as financially sustainable operation. With minimum greenhouse gas emissions and high efficiencies, they deliver an affordable solution to cleaner, greener heating that can lead to better performance – and ultimately, a better bottom line.
As attention centres on air quality and pollution from NOx emissions, it is worth noting that condensing boilers offer both minimum carbon emissions and ultra-low NOx – with emissions as low as 35mg/kWh.
As a result, they easily comply with current and future NOx regulations – from the Clean Air Act to the 2018 Ecodesign of Energy-related Products Directive (ErP). This will enforce maximum NOx emissions of 56mg/kWh for gas and liquefied petroleum gas (LPG) boilers and a maximum of 120mg/kWh for oil fired boilers, up to and including 400kW.
At the same time, condensing boilers meet the need for reliable, consistent temperatures to protect the fabric of the UK’s historic buildings. Maintaining a constant temperature is crucial in these older buildings as it helps prevent damage to the fabric and the valuable contents that many house. The reduced operating costs also help ensure the long-term use of the building, protecting our heritage for future generations.
Forward-thinking manufacturers have integrated time and temperature controls as standard into the latest generation of condensing boilers, encouraging more accurate control for reduced waste. These controls are designed to be easier to use, too, with an intuitive interface that offers both user and engineer entry. So FMs can quickly access the information that will help with maintenance – such as the fault history or the number of starts – or change settings when required.
“MAINTAINING A CONSTANT
TEMPERATURE IS CRUCIAL.”
With many manufacturers offering free BIM files on their condensing boiler range, this assists the facilities management cycle by providing improved asset management. Flexible design options, such as the ability to install multiple wall-hung condensing boilers on a cascade or bespoke- designed rig system, also increase overall efficiencies. At the same, the multiple boiler arrangement ensures reliable service.
Where heating’s concerned, it’s time for proactive future- proofing. Boilers have been with us for years, but the advances in condensing boiler technology are outstanding. Meticulously designed and engineered, this is high-quality, high-performance technology that can transform the energy and environmental performance of a building – and make a facilities manager’s work that bit easier.
