Evinox Energy Supply Canary Wharf’s New District, Wood Wharf

CGI of Canary Wharf’s new district, Wood Wharf

A new urban district is being created in London’s Canary Wharf, which when complete will feature up to 3,600 new homes, a GP’s surgery, a two form primary school for 420 children, 490,000sq ft of retail space and eight acres of public spaces squares and parks. The development, called Wood Wharf, has been designed to provide a new residential led, mixed use, waterside community and is expected to be completed by 2023.

The scheme was approved by Tower Hamlets Council in 2014, which described its design as “innovative”. In recognition of this innovation, Wood Wharf won the Tall Buildings category of the MIPIM Architectural Review Future Project Awards in 2014.

Working with the developer, Canary Wharf Group (CWG), in combination with SES Engineering Services, Emico and Haydon Mechanical & Electrical contractors, Evinox Energy supplied heating and cooling interface units for 1330 apartments for the first phases of this development, with more to follow for the remaining phases.

Homes are all connected to a district heating network, with each apartment featuring a ModuSat XR-ECO Twin Plate heat interface unit for the supply of heating and hot water and a ModuSat Single Plate interface unit to provide cooling.

Tested by BSRIA to project design parameters

Interface units were tested by BSRIA as a requirement of this project, something Evinox were happy to undertake, confident their first-class product manufacturing and performance would exceed the required results.

Peter Linehan, Evinox Technical Sales Manager comments, “The main objective of the testing was to confirm the performance of the heating and cooling units under the specific design parameters of Wood Wharf phases A2/A3, E1/E2. The method statement was based upon three different sources; BESA UK Standard for Heat Interface Units Technical Specification, BSRIA BTS 2/2015 Test Method for Heat Interface Units and recommendations from the clients commissioning company.”

Peter continued, “Evinox’s ModuSat XR-ECO TP HIU’s and ModuSat SP CIU’s were submitted, with a total of 8 units tested at the BSRIA Test House. These included each building’s most common HIU/CIU model and high load units. The interface units achieved excellent results, performing to the project requirements, which culminated in an order for the first 5 phases of the Wood Wharf development.”

Flexible manufacturing capabilities

In addition to the efficient performance of the ModuSat units, Evinox equipment was also chosen due to the flexibility of manufacturing and short delivery timescales. “On-time” delivery schedules were critical for this project, as some of the equipment was being built into prefabricated pods by a third party prior to delivery to site.

Their range of heat interface units are designed and developed internally by technical engineers to UK standards, and built in Evinox’s own production facility in Brasov Romania by partner Romradiatoare, using lean manufacturing principles. Working closely with component suppliers enables them to deliver bespoke units, built to project specific requirements, in a timely manner.

World-leading components

One of the key components used in every ModuSat HIU, is the high efficiency plate heat exchanger from SWEP, who are a world-leading supplier of brazed plate heat exchangers for HVAC and industrial applications. Evinox’s ModuSat XR-ECO HIU delivers impressive, ultra-low DHW return temperatures to the primary network by incorporating SWEP high efficiency domestic hot water plate heat exchangers with volumetrics that encourage turbulent flow. This contributes to excellent annual Volume Weighted Return Temperatures and system operating efficiency.

Market survey shows Rinnai tops for quality product in continuous flow water heating

RINNAI HOT WATER – INSTANT, CONTINUOUS, LIMITLESS AND SENSIBLY ECONOMIC FOR EVERY TYPE OF COMMERCIAL SITE…

Plumbing and heating engineers have reviewed and rated Rinnai continuous flow units and systems as a leader in a recent survey into hot water heating delivery systems and products, identifying the company as having ‘superior quality’ to competitor products.

The survey showed respondents – all Gas Safe registered engineers – answered questions regarding overall satisfaction, brand awareness and product quality. Rinnai came top on product quality – and technical service, in particular.

Over 70% of those surveyed stated they were regular customers and identified ‘strongly’ that ‘quality of products’ and no ‘call backs to site’ as being the main reasons for their views.

Over 65% of respondents said that the quality of Rinnai’s product offering is ‘superior’ to the claimed market leaders with a further 85% indicating that the brand, including all elements of product range, reliability, innovation and customer service, is a genuine market leader.

Rinnai units and systems are now the number one choice for large buildings and businesses with a heavy demand for constant hot water or where high peaks of demand occur at certain times. The water handling capacity is infinite as units can be installed to ‘cascade’.

The benefits for the end user are big savings on fuel over other forms of water heating solutions, with the added advantage that there is no need to give up valuable space to install a cylinder. And there are no standing losses to account for as occur with traditional stored hot water systems.

The Rinnai system produces useable hot water on demand, at the turn of a tap or the push of a shower button. The relatively compact footprint of the units also means they can be housed in tight spaces and still be easily accessible for maintenance and servicing.

According to Rinnai’s Chris Goggin: “We believe our range represents the best value-for-money commercial hot water solution on the market today, and it can be delivered direct to site in one complete, easy to manage package. Its impressive energy performance ratings also make it a highly desirable development at a time when everybody is looking at decreasing energy bills and maximising energy efficiency.”

The condensing process delivers 95% thermal efficiency, which translates to significant energy savings when compared to standard on-demand water heaters. Rinnai’s high efficiency condensing range of continuous flow water heaters, including the HDC1500 with its 96-97% gross efficiency, covers a vast number of requirements.

Rinnai condensing continuous flow water heaters are low NoX, less than 50mg with gross efficiencies of 96-97% and recovery of 740 litres per hour at 50° Delta. All units are A rated on ErP.

‘Smart Design’ boxes ward off the legionella threat

Chris Goggin of Rinnai looks at how smart design and control options can design out legionella proliferation

Legionella control and risk avoidance thereof are top of the list when designing heating and hot water systems.

The whole supply chain – manufacturers and distributors through contractors to end-users – need to plan and design systems to eliminate the risk of Legionella. It is one area where avoidance and prevention are the only sensible action to take to avoid problems further down the road.

Our modern lifestyle demands that hot water is available on tap at any time, day or night. So how can installers and designers reduce the fear of Legionella breaking out – and give peace of mind to customers and end-users?

Quite simple – limit the volume of storage on your hot water system.

A glance through the Health & Safety Executive ‘Approved Code of Practice’ highlights the vast amount of detailed maintenance needed to keep a stored hot water system Legionella free; the level of work involved is time consuming, expensive and must be adhered to religiously.

According to the HSE stored hot water systems present an enhanced risk for the proliferation of Legionella, especially at the base of calorifiers where the incoming water merges with the existing hot water.

Legionella bacteria multiply where temperatures are between 20-45°C. Water at the base of the calorifier is liable to collect sedimented organic and mineral deposits, which support bacterial growth, including Legionella, which is then distributed throughout the system.

To ensure total safety, therefore, the whole water contents of the calorifier, including at the base, must be heated to a temperature of 60˚C for one hour each day.

A lot of these problems are solved by choosing to install a continuous flow hot water heating system. With a gas-fired continuous flow system there is no cylinder to cause problems because the cold water enters the water heater directly from the mains and is immediately heated to advisory levels.

With Rinnai continuous flow units water temperature for distribution is accurate to ±1˚C. The fact that there is no stratification as there is no storage ensures permanent even temperature. There is no requirement to heat a volume of water just to ensure the elimination of Legionella bacteria as the minimum temperature that a continuous flow unit achieves exceeds advisory levels.

However, when considering design parameters that incorporate secondary return systems pipework and dead legs can act as water storage. ACOP L8 (Legionella Guidance) highlights that (continuous forms of instantaneous) systems installed close to the point of use have a greatly reduced risk of legionella proliferation. Despite this in many instances commercial applications are designed around a secondary hot water return.

So, when the taps or shower heads stop running, after use, the pipework will be full of cooling water capable of breeding Legionella bacteria; therefore you do have stored water and appropriate safeguards must be put in place.

So, what is a smart design consideration to eliminate any risk of Legionella bacteria multiplying in a hot water system without keeping water circulating constantly at 60 degrees? The technology is available in the form of smart controls linked to the water heating system, inside which is a timer channel programme and a temperature controller. The timer will over-ride the temperature control for a short period and then revert back to safe levels. This combination allows for safe running of water at 42°C core temperature during the day and thermal shock the system at 60°C intermittently at times when the building is not in use. By the time the building opens again, core temperature is back down to 42°C for safe use.

Some parts of the hot water system, such as rarely used shower heads or terminal fittings, will require regular maintenance and frequent checks to ensure the hot water system is operating correctly.

It is a very simple technology that takes advantage of innate high-tech controls within the water heater, it eliminates risk from Legionella bacteria and is ideal for use in care homes, hospitals and sports clubs – any large or small scale site.

Rinnai hot water – the Solo Stored range

Rinnai, the world-renowned innovator for every possible type of commercial site, has revolutionised the supply and delivery of hot water units and systems since the launch of its fully electronically-controlled gas-fired continuous flow product ranges.

One major part of the Rinnai Infinity condensing water heaters is the Solo range – a highly efficient Heavy-Duty gas-fired recirculatory water heater with a completely insulated stainless steel storage cylinder.

The combination of continuous flow units with a storage cylinder for pre-heated hot water allows for periods of peak hour use. This is of importance at those sites where limited gas services may dictate the use and application of water heating systems. The Rinnai Solo answers this problem – with system efficiency, ease of installation and end-user satisfaction.

Rinnai’s Infinity Solo low NOX water heaters can be used for the ‘Direct to Outlet’ system, and secondary return systems. Infinity Solo will deliver a constant output temperature of 60°C or higher, ensuring stored water is at levels that significantly reduce any risk of legionella proliferation.

The design parameters of this product – it is all in one compact footprint – empowering specifiers, designers, installers and engineers to benefit from unique Rinnai technology in applications it was once not previously possible.

For instance, the Infinity Solo has 35kW, 37kW and 54kW sized heat engines, ensuring sites with a smaller gas meter can readily use this technology. The larger Infinity Solo model will also act as a high-efficiency alternative to gas fired storage appliances that still exist in today’s market and can be easily installed on a ‘like for like’ basis where plant room services are concerned.

The cylinder is stainless steel, and this reduces the weight compared to glass lined models, and it makes transportation and installation a lot easier. As well as the difference in weight, the cylinders also have extremely low heat loss figures (as low as 1.41kW/h day), so the user pays less to maintain the heat within the tank.

One other benefit of the Infinity Solo using a stainless-steel cylinder is that the life expectancy of the material is far greater than that of a glass-lined equivalent as glass can suffer from thermal shock causing it to crack after a period of time.

Certain Infinity Solo models are renewables compatible and supplied pre-fitted with a coil, meaning that the primary energy source will always be from renewable gains and the complementary Rinnai water heater will only apply the precise amount of gas to boost the difference in temperature.

Rinnai’s Infinity brand carries the widest range of condensing gas-fired water heating units and systems- and all are A rated on ErP – on the market today with the most impressive efficiencies in operation, leading the field in technological innovation.

Key Features of the Solo range are: Stainless steel cylinder with high thermal efficiency and Ultra Low standing heat loss; Highly efficient continuous flow water heater is used as the heating booster; Rinnai Patented Lean-rich Low NOx burner (Solo20 & Solo32 only); Compatible with Renewable heating source through the renewable pipe in the cylinder (Solo20 & Solo32 only); Industry leading higher modulating ratio; Compact design for limited space; Inbuilt lime scale detector; Inbuilt immersion heater for the emergency backup; Easy read fault diagnostics via Status monitor; 10 years cylinder warranty (subject to terms & conditions).

Rinnai hot water – instant, continuous, limitless and sensibly economic

Rinnai’s Infinity range of ErP A-rated continuous flow gas fired water heaters now includes many models specifically designed for all light commercial and larger domestic sites. The Rinnai units guarantee the highest efficiencies and lowest running costs at consistent temperatures 24/7 compared to any method of hot water delivery in lighter commercial sites.

The Rinnai Infinity range of continuous flow – sometimes referred to as ‘tankless’ – water heating units are being specified and installed in domestic properties, cafes, pubs, restaurants, offices, shops, hairdressers, commercial units, caravan parks and leisure facilities as installers and end users become aware of their energy & cost saving benefits.

The reason for the increase in uptake is that continuous flow heater systems are proven to be more energy efficient than conventional storage systems and are now experts’ preferred method of hot water provision. Rinnai units easily cater for any size projects that need high volumes of water at intermittent times of day delivered at accurate Rinnai’s Infinity multipoint 16i water heater, for example, eliminates the problem of sudden changes in water temperature, resulting in cold showers or scalding hot baths – the water temperature you set is the water temperature you get. So, if somebody is happily showering at 42°C and a tap is turned on to draw a bath elsewhere in the property, the temperature does not vary, and there is no chance of either user running out of hot water.

The Rinnai Infinity 16i interior model measures 675 x 370 x 139mm and weighs in at 18kg – a one-man lift. The room sealed unit has a temperature range of 35°C to 60°C with direct electronic ignition. Gas consumption ranges between 4.7kW-6.5kW for Natural Gas and 4.9kW-36.8kW when using propane. Hot water delivery flow is an impressive 16ltr max flow. Nominal operation pressure is 1-7 bar and it uses a 230V AC 50Hz 1ph power supply with an electrical consumption of 68W.

Meanwhile, where an external installation is required, the Rinnai Infinity 17e external multipoint water heater offers greater flexibility at the design stage and offers a viable solution where flue runs are problematic or internal space is not available. Capable of flow rates of up to 510 litres per hour at a 50°C rise, the 17e is suitable for multiple applications and can be specified for use with Natural Gas or propane.

The 17e has full frost protection and is available with a range of external ancillary items, including pipe cover box – and security cage where necessary.

The Infinity 11i interior unit differs from the 16i as it weighs 2kg less at 16kg and consumes 6.10kW-21.60kW of Natural Gas and has an 11-metre maximum flow.

Restaurants and domestic properties are prime examples of sites that can truly benefit from continuous water as they require high volumes at intermittent times of the day delivered at accurate temperatures to ensure user comfort and safety, making Rinnai Multipoint Tankless 11i the ideal solution to your hot water requirements.

Key Features of the 24kW Rinnai 11i are: Compact & lightweight unit for easy installation; Robust, durable heat exchanger; User friendly digital controls; In-built frost protection; Ideal replacement for large obtrusive and bulky cylinder; Compact design to fit a limited space.

Continuous flow water heaters are also favoured under the guidance of ACOP L8 (Legionella guidelines) as the units are usually cited close to the outlets in such installations as restaurants, where the system turnover is frequent and store volumes are small meaning legionella risk is minimal.

Rinnai hot water – instant, continuous, limitless and sensibly economic

Installers, specifiers and end users’ installers have the most practical and economically viable solution for all domestic and commercial hot water heating and delivery needs in Rinnai’s comprehensive range of energy efficient A rated, electronically controlled continuous flow gas fired units and systems.

The natural gas or LPG water heaters guarantee a limitless supply of accurately temperature controlled safe and useable hot water, time after time after time to any type or size of site or application. The Rinnai range delivers energy saving performance and low greenhouse emissions through new low NOx burner technology.

All units and systems can be installed as stand-alone or manifolded to provide unlimited hot water for the largest of all commercial sites such as big hotels, busy gyms, high rise offices etc.

Water temperature is and can be pre-set through easy-to-use built in digital controls, eliminating the risk of scalding and potentially eradicating the need for thermostatic mixing valves. Water can be used simultaneously at several points of delivery with no fluctuation of temperature. The newly updated Rinnai Infinity range is designed for use directly off the mains, with no need for large, ungainly and energy inefficient storage vessels.

For example, Rinnai’s Infinity 16i continuous flow water heater is designed to meet the hot water needs of domestic and light commercial applications. The Infinity 16i, weighing just 18kg and measuring less than 675mm (H) x 139mm (W), has a delivery capacity of 15.2 litres per minute, at a temperature rise of 25°.

Rinnai Heavy Duty water heaters are high efficiency gas continuous flow water heaters with outputs up to 69kW. The Rinnai Heavy Duty HD50i Internal water heater is a wall hung, gas fired, continuous flow water heater capable of producing hot water at 770 litres per hour at a 50°C rise. The HD50i has a 125mm concentric flue which can be extended up to 15m, less 1m per 45° bend.

Compact and reliable, the HD50i operates between 1-10 bar pressure, which is suitable for mains and systems with boost pumps. Incoming water temperatures in excess of 60°C are accepted, making the HD50i suitable for secondary return systems. Water can be delivered at high volume with minimum gas consumption. All models have full electronic ignition with no pilot light and operate on demand only, consuming no gas when not in use.

All Rinnai internal HDC condensing continuous flow water heaters, are room-sealed, power flue appliances while the external weatherproof models have forced exhaust which enables them to be compact, saving both floor and wall space.

Rinnai’s unique condensing technology incorporates two heat exchangers to achieve optimum water heating generated from every cubic metre of Natural Gas or LPG. The condensing process delivers up to 95% thermal efficiency, which translates to significant energy savings when compared to standard on-demand water heaters or conventional stored systems.

For applications where the use of stored hot water cannot be avoided, i.e. in refurbishments where there may be a constraint on the amount of gas available, usually through the gas main size, Rinnai’s ‘pack’ system covers this shortfall by fitting a small amount of storage capacity.

Rinnai Gas Hot Water Storage Pack represents the best value-for-money solution on the market today with everything delivered direct to site in one complete package

The pack consists of up to five heavy duty water heaters with an equal number of flue kits (for internal heaters) or an equal number of pipe cover boxes (for external models) and sufficient valve packs. Also included is one hot water storage vessel (stainless steel 300L, 500L or 800L glass lined steel) along with necessary valves and one primary pump with valves and one unvented kit. Add to this an expansion vessel of either 50L or 80L capacity, and all relevant valves. Common header flue systems are also available to further stream line the installation.

Typical applications for the commercial ranges include cafés, nurseries, factories and offices, laundries, hotels and restaurants, sports clubs, shower blocks in caravan parks – and many more.

Rinnai has also embraced renewables in the form of the Rinnai Booster, which, it claims, is the most energy efficient boosting solution on the market today. The water heater maximises solar gain, as it only functions and consumes energy when more hot water is needed to boost the solar gain, meaning that the true impact of solar is being achieved. The rest of the time the unit is inactive.

Rinnai continuous flow hot water systems deliver on all levels in a cost effective and practical manner. Easy to install and operate the units provide a flexible and energy efficient solution for domestic applications and for all sectors of business and industry.

Rinnai – combined heating and hot water systems

Rinnai is now offering a complete package in a combined heating and hot water system for all commercial and domestic applications.

Rinnai is offering three sizes of boiler –50kW, 75kW and 100kW –to its range of HE continuous flow gas water heaters, thus giving a one-stop shop to installers. The package, for all a site’s heating and hot water needs – are delivered direct to site or wherever needed. Rinnai can also offer compete flexibility when it comes to designing combined systems.

Lots of installations utilise Rinnai’s proven, energy efficient continuous flow water heaters use multiple units for example, schools, hotels and gyms and spas. Now installers can very easily manifold two or three Rinnai Infinity continuous flow water heaters with, for example, two boilers via a common flue and on the same cascade rig.

Rinnai UK Associate Director Chris Goggin says “System thinking is what is going to give us the edge as we head into a future where fuel prices are going to need to be managed with pin-point precision.”

This ‘system thinking’ approach has led Rinnai to offer a service to design and deliver a complete heating and hot water system in one easy to install, fully specified and energy efficient ‘pack’ delivered direct to site meeting all the demands of the client in one seamless operation.

“Why would busy installers and end users want waste their time planning and then assembling all the parts of a jigsaw when Rinnai can specify, design and deliver the total solution?”, says Goggin.

“System thinking is so much more effective from design to delivery, through installation and throughout the system’s life time,” concludes Goggin.

A total solution including water heaters, flues, scale protection, unvented cylinders, valves, prefabrication racks, advanced BMS controls – even water sampling equipment – can be specified, designed and delivered by Rinnai.

Get the right size hot water heating unit & system to fit the site

New from Rinnai, the UK’s leader in continuous flow hot water heating, is a Site Sizing Service designed to give the right amount of hot water delivery to meet existing and planned needs. The new service initiative from Rinnai – available over email, iPhone and site visit – is to give contractors and users the right mix of products and system which fit the needs of the site, rather than a ‘one size fits all approach’ seen with traditional hot water heating systems.

“Every site is different, as all installers know, and the tradition of oversizing a system ‘just in case’ is a very costly way for a site to have hot water on demand. The very basis of our product concept is that the end-user only pays for the fuel to heat the hot water at the point of use. There are very few sites that might need a stored hot water facility – but this is very expensive – its rather like keeping a car’s engine running just in case you want to drive it. It is as simple as that,” says Rinnai head of Operations, Chris Goggin.

He adds, “We are inviting contractors, designers, installers, end-users and consultants to contact us in person to discuss their new installations so that we can recommend the right system specific to the site. Our product can cope with virtually any size of commercial site – hotels, hospitals, schools, office blocks and larger residential properties and we have proven systems configured to cope with the biggest commercial premises – right through to Government departments such as the Welsh Office or 350 plus bed hotels. The complete, bespoke and personalised system is designed for the specific need of the site or user and we have a proven record of adding significant value to our customers.

The Rinnai product range includes the Infinity HDC1600i, a premium condensing hot water heater tested to below 20 ppm NOx, producing the lowest emissions on the market, with 97% gross efficiencies.

Also in this established and proven range of award winning products is the condensing HDC1200 internal and external models which give an energy performance of 107% net efficiency while the larger Rinnai HDC1500 internal and external models have 105% net efficiency. Rinnai Infinity condensing units also exceed all the demands of Part L Building Regulations.

The Rinnai HD50i internal water heater and HD70e external water heater offer greater flexibility at the design stage and can offer an alternative solution where flue runs are problematic or internal space is not available. They are excellent units for refurbishment projects.

Using a modular system of either internal or external Rinnai HD or HDC condensing water heaters and a stainless steel storage vessel, demands in excess of 20,000 litres per hour can be satisfied. Rinnai Infinity Plus Storage packs are delivered direct to site in one complete package.

Rinnai units are ‘renewables ready’ when used as a gas booster to solar thermal or heat pump installations in maximizing renewable heat gains. It is the only booster that ensures a hot shower or bath any time of the day or night. The rest of the time the gas fired unit is inactive minimizing energy usage.

Rinnai’s development and investment in integral smart controls for its appliances enable smart integration with sophisticated BMS systems allowing multi data monitoring which in turn identifies areas where energy, service and breakdown efficiencies can be improved. Each digital remote controller can be individually programmed, to deliver temperature accurate hot water for washing and cleaning however the water heater can only deliver one set temperature at any time. Remote temperature controllers cannot override the master temperature setting made with the DIP switches within the heater ensuring safety. Controllers can also deliver basic fault diagnosis.

Rinnai also fields a common header flue system to streamline manifolded installations of its award-winning Infinity condensing units.

Another simple but effective idea which safeguards against lime scale build up occurring in Rinnai continuous flow water heaters a scale control system continually monitors the appliances for lime scale deposits around the heat exchanger.

Also in the range is the Infinity Solo. This is a Rinnai hot water heating unit which combines the advanced technology of its wall mounted water heaters with a stainless steel storage cylinder all in one. And it boasts very low heat loss figures.
