Five Remeha Quinta Ace
160 condensing boilers and an Andrews Water Heaters ECOflo EC380/1400
condensing water heater have been installed at Archbishop Ilsley School in
Birmingham to supply energy-efficient heating and hot water with reduced
environmental impact.
This large secondary
school and sixth form college provides excellent sports facilities for its
students that are also available for hire by the wider community. Dated
non-condensing boilers and an ageing hot water cylinder previously served the
sports hall, gymnasium, swimming pool, changing rooms and shower facilities.
When the time came to
replace the old plant, reliability and energy efficiency were the key
requirements for the School.
Mechanical heating
engineers Spa Gas installed the new school boilers and water heater. Director
Mark Fry said: “Reliability was a priority for the School to achieve and
maintain a comfortable environment within the sports centre, while providing
hot water for the swimming pool and showers. Energy efficiency was also a major
consideration to avoid unnecessarily high bills and emissions.”
Five Remeha Quinta Ace
160 boilers, with a combined output of 800 kW, high gross efficiencies of up to
99% and ultra-low NOx emissions, were selected as the most energy-efficient
solution to meet the fluctuating demand for space heating. With a one-piece
cast aluminium heat exchanger designed for reliable, high performance, these
condensing boilers offer long-term high heating efficiencies at the School and
cleaner, more environmentally-friendly operation.
The Quinta Ace 160 is
one of the largest output wall-hung boilers on the European market with an
unrivalled output to physical size ratio. Back-to-back and linear cascade
options for up to eight boilers provide specifiers and contractors with greater
design flexibility which is particularly beneficial in plant rooms with
restricted available space.
Installing
fully-modulating boilers in a cascade arrangement increases the turndown ratio
which allows them to meet fluctuating heat demand more accurately and reduce
energy waste. This configuration also supports non-disruptive future servicing
and maintenance.
“The ability to
cascade the five boilers not only resulted in a neat, compact installation, but
made the project simpler and faster,” Mark said. “In fact, the biggest
challenge was getting the old boilers out of the plant room!”
The hot
water supply for the School’s sports facilities was met by an Andrews Water
Heaters ECOflo fully-condensing direct-fired water heater. The installed unit
has a storage capacity of 380 litres, an output of 79.1 kW and a recovery rate
of 1400 litres/hour at a 50°C temperature rise. This water heater range features
a low NOx pre-mix power burner and a gross efficiency of up to 98% to keep
running costs to a minimum.
“We have installed a
lot of Remeha and Andrews Water Heaters products over the years and would
always recommend them for their proven reliability,” added Mark. “This is
backed up by the excellent aftersales support provided and good availability of
parts.”
The new boilers and
water heater have been commissioned for optimum performance. Now fully
operational, Archbishop Ilsley School is benefiting from the more reliable,
energy-saving heating and hot water provision and anticipating lower energy
costs moving forward.
“We’re
very pleased with how the work has gone,” said a school spokesperson. “There
was minimal disruption during the changeover and we’re delighted that the
heating system has been working well ever since.”
Remeha and Andrews
Water Heaters are part of the Baxi Heating Group.
