isitors to Bristol Lido are used to a warm welcome from staff but now, they’re guaranteed another type of warmth throughout the year following the replacement of four old, inefficient boilers with two ATAG XL110 commercial boilers.

The newly re-vamped and restored Grade II Listed Lido opened on December 13, 2008 and is now used for a variety of occasions, from daily swims to celebrations and holidays.


Installed by Octagon Heating Services, the two ATAG XL110 boilers have a combined output of 190kW, supplying domestic hot water and heating for the restaurant, pool and spa.


“Our customers rightly demand high


quality, high specification equipment together with the optimum in service support,” said Octagon Heating Services’ Business Development Manager, Colin Green. “Increasingly, with climate change they also seek ever higher efficiencies and

Replacing 4,359 light fittings with LED lighting at the firm’s national distribution centre (NDC) in Leamington Spa will achieve annual energy savings of £100,000. Wolseley UK has been awarded a grant of £50,000 towards the project from the Department of Energy and Climate Change under the Electricity Demand Reduction (EDR) pilot scheme Just 18 companies, including Network Rail, BAE Systems and Tata Steel UK, met the criteria for the EDR scheme, which will fund 10% of Wolseley UK’s LED project. By proactively investing into the scheme, the plumbing and heating merchant is reinforcing its commitment to finding sustainable energy solutions that benefit the environment as well as the business. Project partners AA Projects and Cloudfm estimate that the NDC’s annual kWh savings equate to approximately 1 mega watt, offering a payback period of approximately 4.6 years.


They estimate that grid electricity demand will reduce by 236,000KWH


n ambitious environmental project from Wolseley UK is set to save enough electricity to power 303


during the months of November to February, between the hours of 4pm to 8pm.


Site Facilities Manager at Wolseley UK, John Page commented: “I am proud that our business is continually investing in schemes and initiatives that reduce our environmental impact. It’s great to be contributing to a UK-wide approach to energy saving, whilst reducing our energy bills too. “We are also pleased to be one of just 18 companies selected for the government’s EDR pilot scheme that aims to reduce demand for electricity at peak times.”


The LED project is due for completion at the end of September.

the most environmentally friendly heating systems. “We found that ATAG Commercial’s XL boilers ticked all the right boxes and were pleased to specify and install them on this prestigious contract.” Featuring ATAG’s 316 stainless steel heat exchanger technology, the XL gives a class leading efficiency of 109.3% (EN677), achieved through seamless upward modulation. High efficiencies combined with NOx emissions, which ATAG believe to be the lowest in its class, make the XL one of the most environmentally friendly boilers on the market today.


There are three models in the XL range with outputs of 65.4kW, 105kW and 130.9kW and these can be configured in multiples of up to 8 units to give a maximum output of 960kW. The boilers can be either wall or frame mounted in line (2 - 8 boilers) or frame mounted back to back (3 - 8 boilers) for simplicity of installation.


A major feature of the XL range is the fact that the maximum output can be achieved in the smallest possible footprint of only 2.7m2. A special Sigram stainless steel condensing/pressure system flue arrangement was designed and installed by Bristol-based The Chimney Centre. “With our old boilers we were always


battling to keep all systems going, but since Octagon Heating Services installed the ATAG boilers we are assured of a consistent flow of hot water for all purposes,” said Arne Ringner, Clifton Lido’s Managing Director.

New Alder Hey Children’s Hospital gains CHP


eolia, the energy management services provider, has won a contract with Alder Hey Children’s Hospital in Liverpool for the delivery of two combined heat and power (CHP) units to its new hospital, ‘Alder Hey in the Park’, which is due for completion this year.


V


Delivered by Veolia’s specialist CHP team, Cogenco, the agreement will see a 500kWe gas-fired CHP and a 500kWe biodiesel CHP installed at the Hospital’s new facilities. By integrating gas and biodiesel-fired units the new energy plant will maximise energy security for the hospital, and deliver carbon savings estimated to be 2,300 tonnes of CO2 per year. The CHP units will supply the state-of-the-art Hospital with power and low-grade hot water. During cogeneration the heat produced as part of the electrical generation process is recovered by the CHP and used to heat water.


This increases the efficiency of fuel utilisation, lowers utilities costs and, in line with the NHS’s carbon reduction target of 26% by 2020, will help to reduce the Hospital’s carbon footprint. Damian Shevloff, Sales Director


Cornwall fire and rescue complex benefits from storm water management S


torm water management specialist Hewitech UK recently supplied its products for a new fire and rescue station at Tolvaddon for the Cornwall Fire & Rescue Service.


The greenfield site project comprises the development of two new buildings where existing facilities in the county will be amalgamated.


Although the site is on a 1 in 7 incline, there was the usual need to ensure correct run-off during storm conditions as well as water storage facilities. Consulting engineers Jenkins & Potter designed the system to allow for the run- off from a 1 in 30 year return storm and to meet the requirement for the run-off produced by a 1 in 100 year (1%AEP) return storm including an allowance for

climate change to be contained on the site and then be discharged at equivalent greenfield rates which were agreed with the Environment Agency via a Flood Risk Assessment.


The sloping site meant that additional storm water storage was needed below the surface of the training yard. An open ditch at the bottom of the site leads water through two pipes into and out of the underground storage provided by Hewitech’s attenuation tanks. The ditch discharges to the adjacent Red River via a two stage flow control device. The footprint on site was restricted so the attenuation tank was shoehorned between two gas mains. As well as the value and performance presented by the Hewitech Variobox, the system was chosen as it could be made in different


sizes and in smaller increments for the exact area that needed to be covered. Hewitech provided 227.45 cubic metres of its Variobox Traffic as a ‘dog-leg’ attenuation tank, with two Controlbox access channels. The Variobox Traffic is 600mm deep and very strong at 400kN per square metre. The access and maintenance channels provided are 500mm in diameter. Controlled discharge is into the adjacent river. Stuart Denslow, project manager at Kier Construction commented: “We found Hewitech very easy to work with. All materials arrived on time and the whole process went very smoothly, with no problems. We are very happy with the result.”

at Cogenco, said: “We are currently commissioning the CHP equipment on site and are expecting the plant to be operational in the second half of this year, with carbon savings realised in 2015.” Founded in 1914, Alder Hey Children’s Hospital is now one of the largest children’s hospitals in Europe, caring for over 270,000 children every year. Veolia, the energy and utilities management specialist has helped more than 100 UK hospitals to meet carbon reduction strategies and reduce costs.
