St Paul’s Cathedral received a boiler upgrade comprising two of Hamworthy Heang’s Wessex ModuMax mk3


WM254/508V modular condensing boilers and two Powerstock indirectfired water heaters in 2016. The result is a reduced carbon footprint and significant savings on gas.


St Paul’s Cathedral is subject to strict regulations, prohibiting alterations without special permissions. Failing boilers meant that a heating and hot water plant refurbishment would need to take those restrictions into account. Robin Bunton from Bunton M & E Services, who advised replacement boilers, commented: “We have used Wessex boilers since they were introduced, and we know they are a very reliable product. They are space saving, great in refurbishment projects and buildings where you can’t change the building fabric, such as St Paul’s.”


Tom Fletcher, Works Manager at St Paul’s Cathedral, added: “Once we understood we needed to replace the Cathedral’s heating and hot water plant, we were set a target of reducing gas usage by 10% once the project was complete in line with


the cathedral’s sustainability ambitions. “In discussions with our M&E consultant, our engineer and examining the constraints of the building, we elected to use the Hamworthy boilers because they offered efficiency as well as significantly reduced disruption to the building during the project because of their small modular form. “Since the installation, we have managed to reduce gas consumption by close to 40%. This means that we have not only reduced our carbon footprint but have also benefited from significant savings on our gas bill, well above our initial project target.”

uTwo Wessex ModuMax mk3 boilers with a combined output of 1,016kW now heat the whole cathedral within one day compared to a week by the previous boilers.


Luceco’s lighting education at Kuwait school


Ease of movement around Abdul Razzak Al Basir Secondary School has been enhanced by improved lighting. Attention was given to the lit route between lessons to ensure quick and safe access for both staff and pupils.


Uniformity of light and good luminaire choice is key when lighting educational establishments. The use of LED LuxPanels prevents intrusion from the luminaire, creating an open space for a large number of people to move around in. IP65 rated Climate LED luminaires were used in workshops, plantrooms, and storage areas, with versatile IP65 rated LED Atlas luminaires used on stairwells and entrances.


uThe school’s theatre features Luceco’s Planum Downlights which provide energy savings of up to 80% when compared with convenonal lighng.


Titan Hibays were installed in sports facilities to achieve the required lux levels. The High Bay comes in 110W and 200W options offering more than 50,000 hours’ maintenance free operation. Restrooms were lit with Carbon Downlights. The school’s theatre has been lit with Platinum Downlights from Luceco providing energy


savings of up to 80% when compared with conventional lighting.


Platinum features easy-fit positive locating swing out tabs and interchangeable bezels and is ideal for use with sensors and lighting controls as well as being designed to retrofit ceiling cut outs of common compact fluorescent downlights. Contemporary Architectural Wall lights and Guardian Pro LED flood lights now light the school’s exterior. Architectural Wall is a surface mounting LED luminaire designed for a creative lighting effect whilst delivering functional lighting outside. Architectural Wall has an attractive anthracite IP65 rated aluminium housing and polycarbonate optic providing a contemporary look. Abdul Razzak Al Basir Secondary School now benefits from the huge advantages of LED energy efficient luminaries, providing cost effective, durable, and safe lighting.

Rinnai has completed an installaon at Peckforton Castle in Cheshire, replacing the old direct fired stored hot water system with two HDC 1500i units, linked to solar panels as the main hot water heang source.


Rinnai continuous flow and solar panels installed at castle


Peckforton Castle is a medieval style Victorian country house and is Grade I listed. Bought by the Naylor family in 2006 it is now a luxury hotel and spa.


Said contractor, Adam Mitchell: “The brief was to create a more efficient system, and at the same time to enact a reduction in stored water volume to give substantial savings in gas fuel consumption. But the new system had to still meet peak demand in the hotel, spa and event facilities.” Rinnai’s award-winning HDC1500i continuous flow water heating units met the brief. The range guarantees the maximum amount of affordable, ecologically friendly, safe-temperature controlled hot water, on demand at any time, by even the busiest commercial user.


Both Rinnai HDC1500i internal and external units turn in an energy performance of 105% net efficiency. They can also be cascaded into Infinity Plus modules comprising a minimum of two HDC1500 units – any number of modules can be


manifolded; therefore, the capacity for never ending ‘cascading’ hot water is infinite. Each module of Infinity Plus cascades for the Rinnai HDC 1500i comes with its own precision engineered rack to streamline installation. A major benefit onsite has been the savings on fuel. Rinnai systems will only raise the temperature of the water if required and these smart condensing water heaters will only increase the temperature by the precise amount needed. This ensures that any solar gains are maximised and ‘boosted’ by a secondary heat source thus guaranteeing the optimisation of both technologies.


Rinnai condensing continuous flow water heaters are low NoX, achieving less than 50mg/ kwh with gross efficiencies of 96-97%. The appliances can delivery in excess of 960 litres per hour at 50° degree rise and all units are A rated within ErP.

Safe, effective pipework solution for London landmark


uViega’s press connecon technology was chosen for the pipe installaon at the historic Queen’s House in Greenwich.

Queen’s House, a Grade I listed building and scheduled ancient monument, is the last surviving section of the palace of Greenwich. It is now part of the Royal Museums Greenwich and houses important paintings, drawings and sculptures. Over the last few years, the building has undergone vital maintenance. The importance of the building meant that materials and methods needed careful consideration. No hot works were permitted on-site, so traditional soldering or brazing of pipework was not possible. M&E maintenance specialist Red100 undertook the work as the latest in a number of contracts to work on the building. The renewal of the pipework included the heating and chilled water systems. The supply for both comes off a header pipe in another building. The contract also included work on the greywater system. Because of the restrictions, press connection technology was chosen for the pipe installation. Viega’s Profipress was selected for use on the copper heating and water pipework while the


stainless steel greywater pipe was connected with Sanpress Inox fittings.


Stephen Phillips, Director at Red100 said: “We had been recommended the Viega systems and were impressed by what we saw when we visited Viega’s production facilities in Germany.”


Due to the historic nature of the building, any water leaking from incomplete or inadvertently unpressed joints had to be avoided. The SC-Contur feature designed into products from across the Viega range, including Profipress and Sanpress Inox, ensure that any missed connections are reliably identified during testing. This avoids potentially damaging failures once the project is complete.


Stephen Phillips concluded: “The installation on Queen’s House went very smoothly and as a result we have subsequently used the Viega systems on other projects.”
