Remeha
Quinta Ace 160 boilers have been installed at the Faculty of Medicine and
Health Sciences at Keele University to optimise heating efficiency and minimise
environmental impact.
Improved
sustainability is a key strategic aim for the University. One of the ways in
which they address this is by ensuring that the heating service operates as
efficiently as possible. This includes upgrading any older boilers to newer,
more energy-efficient equipment.
Condensing
boilers are around 11% more efficient than non-condensing boilers. Replacing
non-condensing boilers with condensing boilers therefore offers considerable
scope for energy savings and carbon reduction. But even condensing models
should be routinely replaced when they come to the end of their lifecycle to
ensure optimum operation and efficiency.
So
when the time came to upgrade the two ageing Remeha 3A boilers and one
non-condensing HE boiler serving the David Weatherall Building, the University
was quick to act.
The
first requirement for the University was to achieve high energy efficiencies
and reduced NOx and CO2 emissions in compliance with Building Regulations.
Access
was a potential obstacle due to the rooftop location of the plant room.
The
University was also keen to achieve the heat demand as efficiently and
effectively as possible, avoiding any disruption and ensuring a comfortable
environment for improved wellbeing and productivity.
To
meet all these requirements, Ford-Mainwaring’s Dave Alcock chose to install
multiple boilers in a modular arrangement rather than select ‘like for like’
larger units. This configuration increases the turndown ratio which enables
fluctuating heat load to be more accurately matched, improving seasonal
efficiencies and reliability. Additionally, it allows the condensing boilers to
operate at part load where they achieve their higher efficiencies.
Ford-Mainwaring’s
project manager Paul Brett, supported by Jon Lewis of Heatech, selected six
Quinta Ace 160 boilers on a preassembled Remeha cascade system.
“We
are familiar with Remeha products, and the Quinta Ace 160 boilers fitted all
the requirements, from capital expenditure and quality to reliability and good
service support,” said Dave.
Given
the rooftop location of the plantroom at the David Weatherall Building, the
modular design brought logistical and financial benefits when it came to
positioning the boilers. The six Quinta Ace 160 boilers were transported to the
rooftop in the lift, where they were installed on a neat, ultra-compact
back-to-back cascade system.
“The
reduced footprint of the Remeha Quinta Ace 160 meant that we avoided having to
crane the boilers into the plantroom which would have incurred additional
costs,” explained Dave.
Installation
was quick and easy for contractors Ford-Mainwaring thanks to Remeha’s time and
labour saving comprehensive cascade system. As a result, changeover was rapid
with minimal disruption.
Good
control keeps heating efficiencies high and emissions low. To achieve this, the
new Remeha boilers have been integrated into the existing Building Management
System at the David Weatherall Building.
Ash
Hulme, Head of Engineering and Planning in the Estates and Development
Directorate at Keele University, is pleased with the outcome. “The project went
extremely well, resulting in a neat installation that delivers the required
high performing heating service and reduced environmental impact,” he said.
“The
design allows easy access to the boilers while the inbuilt redundancy makes
servicing and maintenance simpler and the heating service more secure and
reliable. As the lead boiler is rotated, the lifecycle of the boilers is also
extended, all of which improves whole life operational costs.”
A
comfortable environment for improved well-being and productivity, generated by
advanced Remeha condensing boiler technology – the Quinta Ace 160 boilers are
providing the fitting solution to high efficiency heating at Keele University’s
leading, state-of-the-art Faculty of Medicine and Health Sciences.
The
Quinta Ace 160 is one of the most advanced wall-hung boilers on the market.
Built on the Remeha Quinta platform, it offers class-leading heat output to
physical size ratio, enabling easier access through doorways and lifts and
greater flexibility in plantroom design. Cascade options for up to eight
boilers, in-line or back-to-back, provide time-saving installation with on-site
assembly. With in-built 0-10V and volt-free contacts, the Quinta Ace 160 can
connect to any BMS without the need for additional parts.
