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 is happy motoring aboard the Bedroam bus

Rinnai, the leader in continuous flow gas fired water heater systems, has had one its products featured on prime-time television, being a fleeting start of the small screen. The Rinnai product, a 17e, was on Channel 4’s “Amazing Spaces” presented by George Clarke

‘Bedroam’ is the brainchild of Ollie Kemp, a farmer, motor racing competitor and enthusiast from Melbourne, Yorkshire. He realized there was a lack of onsite accommodation at events that would allow competitors to stay close to their expensive and irreplaceable racing gear and has been quick to come up with an innovative idea.

The constructive and enterprising result of Ollie Kemp’s well observed discontent is the Bedroam bus, complete with 18 Japanese-style pod bedrooms. As well as using it himself for motorsport meets, Bedroam is available to hire. “If you can’t get a hotel when you’re going to a wedding or don’t want to camp at a festival then this is the perfect solution,” he told George Clarke of ‘Amazing Spaces’. Ollie’s industrious endeavouring has resulted with his new business being inundated with bookings.

The Bedroam has two fully-equipped and fully-functional bathrooms with shower, toilet and sink. Sinks and showers are supplied with safe temperature controlled hot water from Rinnai Infinity water heaters working on LPG, complete with MC91 controller, via motion sensor-operated taps. Two Rinnai Infinity 17e external units fitted to the back of the bus drawing water from a bespoke designed tank designed and supplied by Barratt Tanks of Ferrybridge, West Yorkshire.

Bedroam also features a range of added contemporary mod-cons for both indoor comfort and outdoor accessibility. Air conditioning, flat screen TVs, comfortable communal area and a multifunctional outdoor space provided by an enclosed awning are also included.

“I first saw the units in operation at an event where there were luxury mobile showers powered by Rinnai products. On my return, I researched Rinnai online and spoke to my friend Andy, a registered Gas Safe engineer also based in Melbourne, who then ordered and undertook the installation.” Andy Dixon, who runs his own plumbing and heating service, explains:

“The units had to go on the back of the bus as Ollie was struggling to find enough space inside. As the bus has an air con system, I had already put a cooling radiator off the back, so the two Rinnai units sat very handily behind that simply hung on a metal grid attached to the back of the bus.

“Piping was easy. I used plastic pipework for both hot and cold outlets running to a little plant room where the back seats of the bus were originally which is directly beneath the bathrooms from where the water is pumped to the header tank via a small 12V.

“Rinnai’s technical guys were very helpful when I phoned them initially for some advice and installation of the units was really easy. I will definitely be using Rinnai again,” says Andy.

The most recent event for the Bedroam was a River Rat Race, which involves contestants doing a 6-kilometer run with obstacles followed by a river swim. The organisers used the Bedroam for their HQ and for the principal runners to shower. They were very happy as the boilers provided more than enough hot water for everybody. An impressive example of efficiency in performance when considering multiple runners would have required showers at separate times throughout the day and night.

“Demand for the Bedroam is phenomenal and I am thinking about building more, maybe even franchising the concept. Rinnai will definitely be used if and when I go ahead with that,’ concludes Ollie.

May the force be with you – MOD chooses Rinnai hot water for shower blocks

Rinnai, the UK leader in hot water systems, has recently completed an installation of 20 HDC 1500i units on shower blocks at an MoD barracks. LPG is the onsite fuel for all the Rinnai systems. Rinnai designed the systems in close co-operation with the local contractor who installed all the units – and the on-site facilities management company.

Rinnai continuous flow condensing units were specified based on previously completed projects on many army camps spread throughout the country.

The end-user, the facilities provider and the installing contractor were all agreed on the excellence of Rinnai product performance, energy savings on fuel, product reliability & durability.

Comprehensive site surveys were completed between Rinnai and the services provider and designs for the systems were based on using two of what was the then plant rooms which housed two extremely large calorifiers. Each plant room was re-engineered with the installation of 10 high performance, high efficiency Rinnai HDC1500i (59.5kW) continuous flow, instantaneous water heaters per plant room.

Rinnai

Each plant room of 10 units were installed in ‘banks’ of five units and set with the Rinnai (MECS) Manifold Electronic Controls. This intelligent energy optimising system brings additional water levels into operation only when required, meaning energy is only used when needed.

The MECS system also ensures system longevity as it ensures that each water heater in the bank is used for the same period of time over its life cycle guaranteeing unnecessary wear and even usage.

Each of the ‘banks’ of five units were also designed and supplied with a common header flue system which provides a compact, neat installation, as well as minimising plant room terminations and offering a quicker, easier installation and a more efficient maintenance programme.

Rinnai’s HDC1500, also known as the Infinity Plus Cascade, is an award-winning range of units. The range was developed to guarantee the maximum amount of affordable, ecologically friendly safe-temperature controlled hot water on demand at any one time by even the heaviest commercial user, even at peak times. In this case an army barracks. The Rinnai 1500i is engineered to the highest standard and is technologically advanced with a host of features giving added value.

Both Rinnai HDC1500 internal and external models turn in an impressive energy performance of 105% net efficiency. *Each Infinity Plus Cascade module comprises a minimum of two HDC1500 units and as any number of modules can be manifolded, the capacity for never ending ‘cascading’ hot water is infinite. Installation is straightforward and simple – each Rinnai HDC 1500i Infinity Plus Cascade comes with its own precision engineered rack, so there is no need to fabricate one or get involved with major re-jigging of pipe work or excessive flueing, the rack eliminates these time-consuming procedures, streamlining installation and helping keep remedial costs to a minimum.

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.

MOD SHOWER UNITS

According to Chris Goggin, “Rinnai Infinity Plus 1500i Cascade represents the best value-for-money commercial hot water solution on the market today, 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 Ministry of Defence (MOD) estate covers around 240,000 hectares. It has 45,000 buildings, including barracks, airfields, naval establishments, military training estate, workshops, offices, messes, family housing, 700 scheduled archaeological monuments and more than 170 ‘sites of special scientific interest’.

According to Chris Goggin, in charge of Operations: “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 our units are A rated on ErP.

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.

* In accordance with BS EN 677

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 system thinking brings business specific hot water systems

Rinnai’s bespoke business specific solutions deliver a new generation of fully integrated, high efficiency hot water systems

Rinnai UK is spearheading a new concept for economic and efficient hot water delivery that brings together all the components of a system in one handy, bespoke designed pack for any kind of business, large or small.

Rinnai UK Associate Director Chris Goggin says that simply supplying a water heater unit (or multiple units) has become an antiquated notion that simply is not good enough. “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.

System thinking has led Rinnai to the point where it can offer a service to design and deliver a complete 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 to waste their time planning and then assembling all the parts of a jigsaw when Rinnai’s water heating experts can specify, design and deliver the total solution?

He says specifiers and designers of both commercial and domestic projects can simply consult with Rinnai engineers and rest assured they will have the right system for the job when they need it and with the minimum of fuss. “What advantage is there in unit thinking when system thinking is so much more effective?” he asks. “And not just at the delivery stage but ongoing through the system’s lifetime.”

“With our integrated system concept we have gone far beyond simply manufacturing a product to being in a position to offer a complete turnkey service from planning through installation and commissioning to on-going maintenance,” says 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.

“The heat generator on the system is Rinnai’s HDC condensing water heater which offers 95% gross efficiency which is maintained for the lifetime of the system due to the design principles and controls. Therefore, the design, combined with the system-thinking approach, promotes best-in-class energy efficiencies.

“The principles of system thinking add value to the customer as they take away compliance issues like legionella control, for example. We have already developed these packages for multiple corporate customers and for our distribution partners, and these pioneering projects have been very well received. The system thinking principle applied by Rinnai is now being adopted mainstream meaning more and more efficient systems are in use.

“A key demand is to provide better on-site efficiency at point of installation and as the system is supplied to site in a pack, this demand has been answered. Using the principles of system thinking we aim to take the headache out of system design and supply complete solutions that go well beyond the heat generator and offer our customers performance and compliance for many years to come.”

“The water heaters (the complete Rinnai range is A-rated under ErP labelling demands) far surpass the thermal heating credit requirements for domestic and commercial hot water systems in new and existing buildings to ensure current and future compliance,” Goggin says, adding: “It is a complete turn-key solution that guarantees easy installation and tight time and labour control and standardisation of both product and spare parts supply.

‘Customers and end-users can be assured that their system is–G3 compliant and has good practice when concerning Legionella (ACOP L8) guidance as well as being best in class under Part L building regulations.

* Rinnai is a BIM steering committee advisor to CIBSE for water heaters, boilers and air heaters and ICOM ‘s chosen expert for the RUK UK review of EN26 and EN89.

Rinnai: space heater range, easy to install, trouble free long life warmth – new additions

Rinnai have added to its range of Energysaver gas fired space heaters which are designed specifically for use in schools, community centres, libraries, conservatories, churches and other large indoor spaces. The range has seen many thousands of installations over the past several years – trouble-free, easy to install and cost effective and efficient operation and performance.

The recent additions to the range are the Rinnai Energysaver 559FT and a new streamlined look to the popular Energysaver 309FT.

Sporting very sleek casing, the heaters simply blend into the background in line with the need of modern interior aesthetics while offering exceptionally high efficiencies in operation and subsequently reduced running costs.

Changes to the Energysaver 559T have been made to the operation board which is now an easy to use touch-control pad sited conveniently and discreetly on top of the appliance, (rather than on the front with a flip up cover). The unit is also supplied with a child lock to eliminate any problem of small hands tampering with the controls.

Add to these advantages are the timer function and eco mode combined with the new unit’s ability to heat big spaces very fast.

The 559FT has an input of 6.4kW and output of 5.2kW. The streamlined unit measures 554mm x 750mm x 250mm.

The Rinnai Energysaver 309FT, like the 559FT, sports a similar sleek casing and turns in net efficiencies of 88%.

It has an input of 3.4kW and output of 2.92kW. The unit measures 695mm x 465mm x 257mm. Natural Gas usage has been pegged at 0.31m3 while LPG consumption is 0.26kg/hr.

Also available is the Energysaver 1004T with its impressive input of 11.6kW and outputs 10.23kW. Its measurements are 670mm x 930mm x 315mm and it has energy efficiencies of 96% under the guidance of Part L 2014. This puts it in the top rank of space heaters in its class.

Like the Energy Saver 559FT and 309FT, the 1004T heater is also suitable for central timer control. This feature allows the building manager to run any number of Rinnai space heaters off a central time clock providing heat to the largest of spaces. The Energysaver Multi controller is not limited to single Energysavers as the flexibility of the system guarantees units can be mixed and matched to satisfy even the most unique of buildings.

Rinnai Energysaver units are very easy to install as they do not need expensive and extensive ductwork, nor do they involve the necessity to run domestic heating circuits for radiators or pipework to boilers. This drastically cuts down on cost and time at the point of installation.

Rinnai’s Energysaver range delivers energy-efficient and consistent warm air powered by Natural Gas and LPG options. The units feature fully modulating burners so heat output and energy input is reduced as the space warms up.

The Rinnai Energysaver range comprises fanned convection-powered flue models that exceed seasonal thermal heating guidance under Building Regs Part L.

In a building with high vaulted ceilings, with conventional convector heaters, the heat will immediately rise to the ceiling. With the Energysaver range Rinnai has successfully come up with a solution that heats from the floor up and by modulating gas usage in relation to room temperature, provides unparalleled levels of comfort combined with efficiency.
