ELCO Heating
Solutions has supplied five THISION L EVO 120kW boilers to Westhaven House in
Weymouth.
The installation was
part of the complete refurbishment of the heating and hot water system at the
Dorset-based care home, with the aim to reduce energy use, emissions and
running costs.
This involved the
property owners, Aster, removing two ageing atmospheric boilers and two direct
gas-fired water heaters, which had all reached the end of their operating
lifecycle and were extremely inefficient to run. They were replaced by a floor
mounted cascade system consisting of five THISION L EVO boilers and two 500L
Gemini calorifiers from ELCO.
In addition, ELCO
also supplied a weather compensation kit, while the boilers’ built in control
is managing the system pumps and diverter valves for two heating zones and the
DHW.
Westhaven House was
built in 2006 and comprises 54 flats for enhanced sheltered accommodation.
Residents benefit from a range of care facilities, with Extra-Care staff
available on-site 24/7. Due to the latest technological advancements offered by
the new ELCO heating equipment, the property and its occupants are benefiting
from highly efficient heating and hot water production. Furthermore, the new
boilers also ensure ultra-low NOx performance of 40mg/kWh, reduced CO2
emissions and considerable gas savings over the year.
Dave Chapman,
Commercial Heating Manager for Aster, said: “We wanted to make big changes to
the care home’s old heating system by removing the old atmospheric boilers and
direct fired water heaters and upgrading them to gas fired boilers with
calorifiers. Having successfully installed the THISION L EVO boilers on another
site, where they have operated faultlessly for months, they were the obvious
choice for the Westhaven project.
“We have increased
the overall output of the system to maximise hot water delivery, with the
modulating capability of the cascade arrangement sure to deliver excellent
efficiencies. We’re so pleased with the new boilers and the service provided by
ELCO that they’ve already been specified on another one of our projects.”
The refurbishment
started following the failure of an atmospheric boiler, leaving the care home
with reduced output and limited DHW. Aster called ELCO’s local Area Sales
Manager, Alan Hough, to help remedy the issue, with ELCO providing an initial
two THISION L EVO boilers within 24hrs, which were fitted and operational
within days of delivery. This was followed by the installation of a further
three units, bringing the total cascade setup to five and the required total
output.
During the
refurbishment, the care home and its occupants required a continuous supply of
hot water. With careful planning prior to the installation, Dave and his team
were able to remove the water heaters from the system and utilise the new
calorifiers for hot water production until the THISION L EVO boilers had been
commissioned.
Part of the success
of the project was the design of the cascade rig and the combined flue system,
which allowed for rapid installation and minimal downtime. Dave added: “The
installation has gone very smoothly, with the equipment now fully operational and
supplying highly efficient heating and hot water to the property. Had it not
been for some nesting seagulls around the flue outlet on the roof, it would
have been even quicker job!”
THISION L EVO is
range of highly efficient wall mounted gas-fired condensing boilers with
outputs from 60kW to 140kW. The boilers utilise the finest technological
features and components, offering customers a highly flexible unit that can be
specified for an extensive range of applications.
Outstanding features
include: a flat metal fibre cold flame burner for extremely low NOx emissions;
a robust stainless steel heat exchanger with double wall geometry providing
superb heat transfer; extensive cascade arrangements for powerful and flexible
systems; plus the latest control functionality to ensure optimum performance.
