PRE-BUILT, SUSTAINABLE, PACKAGED E-HOT WATER SYSTEM FROM ADVECO

Hot water and heating specialist Adveco, offers educational facilities with large hot water demands but space limitations a complete, highly-efficient, low carbon resolution with its Packaged e-Hot Water System.

This prefabricated all-electric water heating system brings together Adveco’s FPi-9 Air Source Heat Pump (ASHP), an Adveco 200L GLC indirect preheat tank, and Adveco 200L GLE direct electric water heater to provide reliable high-temperature water in a convenient, packaged system housed in a compact GRP housing.

Bill Sinclair, technical director, Adveco says, “The Packaged e-Hot Water System leverages all the advantages of off-site construction to provide a standardised, resilient, environmentally friendly, low carbon, hot water system that helps reduce both a school building’s energy consumption and operational costs across its lifetime.”

Adveco’s Packaged e-Hot Water System is ideal for new build projects or refurbishment where space is at a premium. The system makes particular use of the FPi-9 ASHP to provide the system preheat from 10°C to 50°C, supplying 70% of the DHW load.

Offsetting 70% of the energy requirement means the Packaged e-Hot Water System can demonstrate a 47% reduction in energy demands and CO² emissions for the same output of 500,000 litres of hot water each year when compared with a similar direct electric-only system. The reduced energy demand also means operational savings can be added to the capital savings secured during the design, supply, and installation phases.

A completely new specification that lowers the heat intensity, without detrimental effect to the demands for hot water, means the Packaged e-Hot Water System is also more resistant to scale, reducing maintenance demands. Should the lead heat source ever fail, the system incorporates an additional emergency backup 6kW immersion heater to provide resilience and surety of hot water.

FILTERING THE OPTIONS TO REDUCE CONTAMINATION RISK

There is an innovative way to make air as fresh as possible within educational buildings, and thus achieve compliance with Government guidelines(*).

 

Gilberts, the UK’s leading independent air movement specialist has developed a range of modular filter boxes to integrate with its innovative stand-alone hybrid natural ventilation unit, the Mistrale Fusion System (MFS).

 

Added during initial installation or retro-fitted to the MFS through- wall or through-window unit, the filter units help minimise ingress of unwanted and/or harmful airborne particulates into the internal space.

 

“Under Government COVID guidance for schools, fresh air from outside should be optimised, and recirculatory solutions set to full fresh air. ” explains Gilberts’ Technical Director Roy Jones. “MFS delivers as standard 8l/s of ventilation: the DfE requirement for a fully-occupied ‘typical’ classroom of 32 people, so exceeds the 5l/s of fresh air the new Guidance recommends.

 

“Adding a filter box- initially or retrospectively- gives added assurance that any pollutants are removed before the air enters the room. And the MFS is a stand alone solution requiring just one system/zone (classroom), further minimising risk of cross-contamination into other air spaces. Thus, educational establishments can optimise the fresh air supply, without any of the disadvantages of having windows open, with all the associated issues with ingress of pollutants, pollen, noise etc which can adversely affect pupil concentration.”

 

Gilberts’ core MFS unit comprises a box fitted through the external façade with louvres, that mixes internal and external air to ventilate the internal space. A mixing damper within modulates airflow to allow the new, fresh air to mix with the warm exhaust air, thus extracting its heat without the need for an exchanger. The integrated low energy fan energises to blend the internal air, ensuring an even distribution of airflow, with control over temperature and CO2 levels within, and maintains a comfortable internal environment for occupants.

 

Just 2 no MFS128 units or 1 x MFS256 unit will ventilate a standard 32-person classroom, achieving the 8litres/sec/person fresh air required by current Department of Education Building Bulletin (BB101) and PBSP guidelines. Each unit also achieves relevant acoustic considerations: its operational ‘noise’ is less than 30dbA and meet SEN (special educational needs) room requirements, and it has been engineered to absorb external noise to keep within the classroom criteria required by BB93. A boost mode also enables a room’s air to be purged for fast redress of air quality and temperature. Heating coil options are also available to provide primary heating to classrooms.

 

Gilberts has further taken care to attain compliance with Building Regulations Approved Document L. The MFS range attains air leakage better than legislative requirements – 5m3/HR/m2, and a U value of 1W/m2/°C. As with all Gilberts’ ventilation solutions, it delivers efficient weather performance via its bespoke louvre system.

 

Founded 50+ years ago, privately owned Gilberts is unique in having its own, on-site (85,000ft2) manufacturing facility, producing engineered solutions, with an in-house test centre. Technical expertise is supported with full in-house testing addressing air movement and combining with computational fluid dynamics CFD).

FREE AUDIT ON ALL ENERGY COSTS FOR HOT WATER DELIVERY

Rinnai is offering all schools FREE energy audits on their hot water systems. The audits are aimed at maximising hot water delivery efficiencies which can result fuel cost savings, alone, of up to 30% on current energy price. The hot water is heated only when it is used – turn the tap off and the energy costs stop immediately.

 

There are also capital expenditure and carbon savings to be included in the final Whole of Life equation.

 

The audit, in close co-operation with each school, measures all data concerning hot water use and presents a full and detailed report.

 

This is all free of any charge.

 

For the owners of one site a manager commented, “We had an old stored water heating cylinder system, it become completely impractical, inefficient and needlessly expensive to run. “Clearly we needed to change to one that could cater for demand fluctuations – for example, showers running after PE, while the kitchens were also working – without running up huge energy bills. The solution wasn’t hard to find with Rinnai continuous flow hot water delivery.

 

“We presented the project to Rinnai’s Technical team who came up with the design, configured the sizes of unit required and delivered the system complete and to a very tight timescale – this was key as the existing water heater had developed a leak and I was extremely mindful that the site had to remain operational.

 

“The Rinnai system has resulted in an energy reduction and gas saving due to higher efficiencies and because we are no longer maintaining large amounts of stored hot water. It’s not rocket science to work that out!” “In terms of gas usage running costs compared to the old wasteful storage system, our bills have virtually been halved since the Rinnai system went live five months ago, which is absolutely tremendous.”

 

Rinnai is the world’s leading manufacturer of continuous flow hot water systems – it makes and sells 2 million units each year. The range of units can be manifolded to supply, limitless hot water to a school site of any size. This means fast, efficient, temperature-controlled water on demand at the point of delivery – kitchens, showers, accommodation blocks, bathrooms, washrooms. It also means far less space spent on plant rooms and no or little maintenance as all units are proven to be robust with a long, long working life.

 

Rinnai is the world-leader at the forefront of creating unit cost advantages for end-users. All units and systems are competitively priced, the units offer all technological advances and innovations, all at a similar cost to lower specification competitor models.

 

Contact the company direct by telephone or email engineer@rinnaiuk.com for your FREE audit on hot water usage on your site

OUTSTANDING MAINTENANCE DELIVERS PEACE OF MIND TO HERSCHEL GRAMMAR SCHOOL

  • Unexpected gas leak was a challenge

Based in Slough, Berkshire, Herschel Grammar School is a selective, co-educational secondary school that was deemed outstanding in all categories in its last Ofsted inspection. Outstanding is the same word used by Judith Vucic, the school’s business manager, when talking about the service and support she receives from Southern Maintenance Solutions (UK) Ltd, (SMS). The company has been providing a full maintenance contract for the school’s heating and plumbing systems for over 10 years. The last two summers have proved particularly busy for the company as in 2019 the old oil boilers were renewed, whilst in 2018, the school had an anxious time when a series of gas leaks were discovered on existing steel pipework in the underground pipe ducts, just weeks before the school was due to open for the new academic year.

“The oil boilers were over 60 years old, more suited for a museum than a vibrant 21st century school with over a thousand pupils, and certainly not very efficient;” commented Vucic. The removal of the boilers, which delivered the hot water and heating for the school’s main three storey building, the sixth form centre and two additional blocks, had been budgeted into the school’s plans since earlier in the year and the work was scheduled and completed during the extended summer holiday period.

SMS were already familiar with the school’s systems having resolved the problem of significant gas leaks in the underground pipes the previous year, 2018. This was a major problem and one, that if it was not resolved safely and swiftly, would prevent the school from opening at the start of the new school year in September. “It was a real shock to learn about the gas leaks and such was the extent of the remedial work required that the school was forced to apply to the Department of Education for emergency funding;” explained Vucic.

Glenn Nicholls, Service Manager, SMS, explains more; ” My first knowledge of this problem was on the 1st August 2018, I looked at it and designed pipe sizes, routes etc and got a quote to the school by 3rd. We started work on the 9th August and the job took 2 men x 12 days to complete. All existing underground pipework was disconnected and left in situ. Then, new surface mounted 89mm, 54mm and 42mm stainless steel pipework totalling 180 meters in length, was installed to pick up existing services. We also had to employ ground workers to dig up 6 meters of driveway for an external section and then make good to a tarmac finish.”

The school secured £40k worth of emergency funding to cover the costs of the unexpected gas problem and the replacement of a leaking calorifier, and both aspects of the programme were completed on time and on budget, much to the relief of the school’s management team. “SMS saved the day. It feels like a real partnership working with their team who are always professional, highly skilled and are always looking to find the best solution for the school, one that not only works but also gives us value for money;” concluded Vucic.

Martyn Neves, Operations Manager at SMS, said; “We are delighted that we have been able to establish and maintain such a longstanding relationship with the team at Herschel Grammar School. We will continue with our maintenance contract for the school and next on the list, in addition to the boilers, is the maintenance 51 fan convector units located across the school, as well as the electric water heater and the water treatment facility.

“With so many schools facing the triple challenge of aging building stock, ever decreasing budgets and a growing demand for greater energy efficiency, companies with the experience and expertise of the SMS team are a vital support for any school’s management team;” said Vucic.

Estimated £38k savings for student block, thanks to Helec

Helec Ltd, a specialist in the specification, design and installation of Combined Heat and Power systems (CHP), are proud to announce the completed supply and commissioning of a CHP solution at Crown Place Norwich (formerly St Stephen Towers), which has been converted by Crown Student Living into student accommodation.

Helec was selected to provide an industry leading, highly efficient, low NOx (Nitrogen Oxide) exhaust gas emitting CHP system for the redevelopment, which is expected to save an estimated £38,000 in energy costs and 204,000 kg ofCO2 emissions per year. Helec specified and supplied two 33 kWe Energimizer EM33NG CHP systems, which were installed in the plant room by building services company F P Hurley in June 2019. The refurbishment of the705-bedroom accommodation block opened in September 2019.

Anthony Isaacs, Project Engineer at F P Hurley, said: “The Energimizer CHP units supplied by Helec are very easy to work with, with plenty of installation information provided to aid the correct installation. Helec’s engineers were also very helpful with regards to getting the units started for the purpose of the Building Management System’s control strategy. This was all done over the phone with ease. I would highly recommend these units to other engineers and consultant specifiers–they’re great items of plant, and Helec are great people to deal with.”

F P Hurley, a mechanical and electrical systems contractor based in Bridgend, South Wales, have been partnering with Crown Student Living over a number of years in order to design and deliver the complete mechanical and electrical services. F P Hurley had previously commissioned Helec with other projects, delivering CHP solutions to new plant rooms within new build student accommodation blocks.

In December 2018, Helec were brought in to commission a solution to the hot water requirements and to help reduce electrical power consumption of Crown Student Living’s Crown Place Cardiff, a 374-bedroom student accommodation block. The requirement was to ensure consistent hot water throughout the   year   while   keeping   costs   to   a   minimum   per   residence.   Taking   into   account   all   individual requirements, an Energimizer EM22NG Combined Heat & Power unit was specified and installed within Two Energimizer CHP systems provided by HELEC the building’s plant room. This CHP system is expected to lead to annual fuel savings of £9,900 and reduce annual CO2 emissions by 56,500kg.

Earlier in 2018, another Crown Student Living project, a new 576-bed student accommodation block, Crown Place Portsmouth, specified and installed two 22 kWe Energimizer EM22NG CHP units to deliver hot water services and on-site electrical power, reducing the need for grid dependency. It was estimated that this CHP system would lead to annual fuel savings worth £21,000, and reduce annual CO2 emissions by 114,000 kg.

Jonathan Passmore, Technical Sales Manager at Helec Ltd, said: “It’s been a pleasure to work with F P Hurley on the CHP systems at Crown Place Cardiff and Crown Place Portsmouth. We look forward to our CHP system at Crown Place Norwich helping Crown Student Services reduce costs and drive down CO2 emissions.”

Anthony Isaacs of F   P   Hurley said: “We   have   used the same CHP units for   all the student accommodation jobs we have done with Crown Student Living. We have been successful with our design and installation to date on all other projects, so we have kept them all the same using the same items of plant throughout. We will almost certainly use the same items of plant on the next projects with Crown Student Living going forward.
