Andrews Water Heaters
Condensing Storage Water Heaters & Commercial Heaters
Andrews’ Largest Solar Thermal Water Heating System for new
Travelodge in Fulham
In Andrews Water Heaters’ largest SOLARflo water heating
installation to date, the newly opened Travelodge in Fulham has been
equipped with 33 solar panels, 3 single coil pre-heat tanks and 2
ECOflo water heaters which supply domestic hot water to the 74
rooms, each of which has an en suite bath or shower room. Developed
by Lombard Asset Management (Bahamas) Limited, the four storey
building accommodates ground floor retail accommodation with the
Travelodge located on three floors above. Renewable energy was a
requirement of planning consent which would not have been granted
without a contribution of 37,000 kWh of energy produced from a solar
DHW system. Since at least 85-90% of the hotel’s rooms have been
occupied every night since it opened, an efficient, reliable and
cost effective source of hot water was essential.
The solar panels are located on the roof, whilst the water heaters,
cylinders and other solar equipment are housed in a mezzanine plant
room above the retail store on the ground floor. Each of the 33
glazed flat plate collectors has an area of 2.55 square metres,
giving a total collector area of 84.15 square metres.
These solar collectors provide 90.8% transmission efficiency, 95%
absorption efficiency and a low emission loss of only 5%. Water is
preheated by the solar collectors, which are positioned to optimise
their solar gain and heat is transferred to the three 1250 litre
single coil cylinders. These in turn supply preheated water to the
two ECOflo 380/1400 water heaters, thereby considerably reducing
consumption of natural gas. The high efficiency, gas-fired,
condensing storage water heaters installed each have a capacity of
380 litres and a recovery rate through 50ºC of 1400 litres per hour.
The SOLARflo water heating package and ECOflo water heaters were
installed by MITIE Engineering Limited who selected the SOLARflo and
ECOflo equipment to meet both end user requirements and space
availability in the plant room. In addition to the glazed flat plate
solar collectors and non-corrosive, stainless steel solar cylinders
the complete SOLARflo package also includes solar controls, pump
station, expansion vessels, first fill of heat transfer fluid and
collector mounting accessories. Matched equipment from a single
source, together with the availability of technical advice
throughout the installation, is a particular benefit of the Andrews
Water Heaters’ product range and after sales service.
The ECOflo high efficiency water heaters feature a low NOx pre-mix
power burner that is quiet in operation, and a gross efficiency up
to 98%, keeping running costs to a minimum. The units incorporate
Vitraglas® silica glass lined tanks which provides protection
against the corrosive effect of hot water and guarantees a longer
working life. Also standard are Correx maintenance free powered
anodes, which substantially reduce service time and costs.
The factory fitted Hydrojet® sediment reduction system on the cold
inlet connection helps to prevent sediment build-up at the base of
the tank, giving a long working life. The option for these
appliances to be flued either vertically or horizontally as room
sealed balanced flue appliances greatly increases siting and
installation flexibility. As with all Andrews water heaters, heat
input and flow are carefully regulated to produce a closely
controlled water temperature and a high temperature anti-legionella
program, which is essential for hotel hot water installations, is
incorporated as standard.
Travelodge was the first budget hotel brand to launch in the UK in
1985 and is now the fastest growing budget hotel chain in the
country, operating 383 hotels, with over 27,000 rooms, in the UK,
Ireland and Spain. In addition, over 20 new hotels are planned this
year, including Travelodge Fulham which is now open for business. By
the time of the 2012 Olympics, Travelodge aims to be the biggest
hotel operator in London.
Andrews Water Heaters is part of Baxi Commercial Division which
includes Potterton Commercial, suppliers of a wide range of gas,
oil-fired and dual fuel commercial boilers featuring the latest
heating technology for energy efficient operation. The breadth of
commercial heating available from this single source is a benefit
which is appreciated by both designers and installers due to readily
available design advice and technical assistance during
installation.
