the units, at a similar height to a vertical-stacking arrangement for example, the modules are all at the same height. This enables maintenance to be carried out easily and safely at a lower level to keep efficiencies high throughout the life of the boiler.
Water quality
Heating and hot water systems perform more efficiently, more safely and more reliably with good- quality water circulating in them, making this a critical factor for consideration at the planning stage. Hydraulically separating the primary and secondary circuits using a plate heat exchanger will prevent any debris or contaminated water entering the new boilers, increasing their longevity and durability while optimising their operational performance and the overall efficiency of the system. Introducing air/dirt separators will also help protect the new boilers and optimise their performance.
Controls
It’s important to note that condensing boilers require a different approach to controls than non-condensing boilers. When installing new boilers onto an old system, for example, it’s advisable to introduce a controls strategy that will include weather
compensation to enable the boilers to run at lower temperatures, where they can operate in condensing mode and achieve their higher efficiencies. The addition of thermostatic radiator valves (TRVs) or temperature zone control will again increase overall seasonal efficiency through full building control.
Disruption
Avoiding disruption to the heating and hot water system during the changeover period can be vital in buildings like schools and hospitals. One option that overcomes this challenge and
addresses all of the previous refurbishment obstacles, is to use offsite fabricated heating solutions for multiple wall hung or floor standing boiler replacement projects.
With turnkey solutions like prefabricated rig systems, all project and site requirements – from space and access limitations to water quality, project- specific controls and optimal pipework for connection to the system – can be addressed in advance at the design stage.
Typically, each boiler rig system will be designed using BIM tools and 3D computer-aided design (CAD) systems. Front-loading the design in this way provides specifiers and contractors with the opportunity to provide input at the early stages, while
Energy efficiency
bringing assurance of a quality outcome. With installation and commissioning reduced
from weeks to just days, turnkey solutions like these minimise disruption through faster project completion. At the same time, they reduce safety issues through controlled off-site fabrication and maximise energy savings benefits through best quality installation.
Time to act
Ensuring that the heating system operates effectively and efficiently is a practical means of avoiding needless energy waste and associated emissions. A reliable, well-controlled heating system will not only minimise building running costs in these difficult times but is central to generating a comfortable and productive environment for returning workers. And where more fresh air needs to be brought into a building’s HVAC system, or windows opened to improve ventilation and prevent transmission of the virus, an efficient heating system will be better able to optimise thermal comfort.
With good manufacturers providing quality solutions backed with expert technical advice and support for best practice heating refurbishment, there’s never been a better to time to prioritise heating efficiency.
