Keele University selects Remeha boilers to provide energy-efficient heating with reduced environmental impact.

Improved sustainability is a key strategic aim for Keele 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. 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.
