Rinnai Infinity 1600e offers lowest low-Nox guaranteed

Rinnai, designer and manufacturer of the A-rated Infinity range of Infinity continuous flow condensing gas fired water heaters, supplies the best energy efficient range of low-NoX water heaters on the market.

Advanced condensing heat exchangers combined with innovative down firing pre-mix burner technology ensure every cubic metre of natural gas or LPG is utilised to the maximum in the Infinity HDC 1600e. The units are renewables-ready and suitable for use as a temperature booster for solar thermal and heat-pump installations. The HDC1600e is also future-proofed against future regulatory and legislative changes.

The renewables-ready low-Nox Infinity HDC 1600e external wall mounted boiler along with the interior HDC 1600i version) utilises Rinnai’s patented pre-mix burner technology with a 14-1 turn down ratio – the largest on the market – of 58.4kw-4.05kw and is ultra quiet in operation.

Integral controls on the units are also a major step forward in achieving best efficiencies whether locally or when integrated into a building management system. Legionella proliferation is also significantly reduced too.

Rinnai has also invented additional ‘SMART’ controls for secondary return DHW systems in the form of an advanced temperature control system which allows for safe running of water at 42°C core temperature during the day and 60°C at a time when the building is closed. By the time the building reopens, core temperature is 42°C for safe use.

“The uptake on the whole series of Rinnai’s low-NoX, high efficiency product, across all sectors, has been nothing short of phenomenal,” says Rinnai UK Associate Director Chris Goggin.

Rinnai Infinity HDC range offers condensing technology with up to 107% gross efficiency, ultra-low-Nox of less than 20 ppm, a widely expansive modulation range of 54kW-4kW and high flow rates of 37/ltr/min. Add to these benefits the peace of mind of an extended warranty, a top A-rating exceeding the demands of eco-labelling legislation, the flexibility of external wall mounting and delivery to site with all relevant accessories and the knowledge that the HDC1600e is future-proofed against future regulatory and legislative changes and it is easy to see why the Rinnai brand is fast growing in popularity among H&V professionals.

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.

Decentralised continuous flow hot water heating systems – an alternative to central plant

Centralised plant rooms for heating and hot water systems are a traditional solution and have been so for many years. But we live in different times where economic and energy efficiency – and legislative compliance – are demanded by users, premises owners and managers in both public and private sectors.

An alternative solution that marries high efficiency and wide ranges of modulation with simplicity of installation and design is the gas fired continuous flow hot water heating unit. These can be manifolded into a hot water system capable of coping with virtually any size of site or application. This system is a process of delivering a continuous flow of hot water at a constant temperature, without the need for storage. Continuous flow will only ever utilise energy whenever heat is needed i.e., the turning on of a tap in a washroom or a kitchen. When the units are in operation and heating water – gas is used – when the user is finished, so is the energy usage. With continuous flow systems, the user can set the required temperature of hot water to suit the needs and demands of the site. So, vulnerable users, such as children, the elderly or less able, can be safeguarded from the risk of scalding. Also, where the site has a secondary recirculating system the temperatures can be set at a level to further minimise the possibility of the proliferation of Legionella bacteria.

Condensing continuous flow hot water solutions qualify for additional energy efficiency points, boosting building energy performance as they far exceed energy efficiencies called for in Part L Building Regulations (Conservation of fuel and power). The systems are also ‘A’ rated under ErP.

Current thinking on the design of systems is moving towards separating the hot water production from the heating system completely as it can give better efficiencies all round. Buildings need hot water all year round. However, better insulation in most buildings, and a greater awareness of energy efficiency, means there is a reduced need for heating input.

In large commercial buildings, centralised heating and hot water systems have traditionally adopted the thermal storage design. These systems are frequently over-sized at the design stage in relation to actual usage on the not too scientific basis of ‘just in case’. This ‘hedging of bets’ approach to system design often leads to excessive safety margins, which in turn adds to the expense of purchase, installation and running costs.

A storage type, conventional system of hot water that must be heated 24/7, 365 days a year to ensure hot water is always available is an anachronism in today’s energy and cost-conscious world. Even if no hot water is drawn off, a standard cylinder, just for example, can lose a maximum of 3Kw of heat a day as a standing loss.

All cylinders suffer from this to some extent and it equates, over a year, to 1095Kw of energy wasted. If you also look at the gas saving alone it equates to 101.8m₃ of gas used.

Decentralised hot water provision was recently installed at a luxury country club and spa in the leafy and very affluent Cheshire countryside. The site operators, having both the contractor and the consultant make calculations on usage and life cycle costings, was adamant that a stored hot water system was not in the frame for the new fit out as it would be “inefficient and expensive”. The company went on to specify 19 gas fired condensing continuous flow units over the whole site to fulfil its huge demand for 20,000 litres per hour of safe, temperature controlled hot water. The heavy-duty units feed executive soaker showers, poolside showers and all changing room ablutions.

Within this complex, the water heaters feed the showers directly so there is no need for re-circulation around the building. With no centralised boiler room having to be incorporated into the plans.

Elsewhere, one local authority in North Wales is currently in the process of replacing its stored hot water systems with manifolded continuous flow systems. The council is set to make considerable savings on running costs. When the water isn’t running the continuous flow, system is not using fuel, which is ideal for the schools’ shut down during the holidays, for example.

These claims and assertions have been borne out by independent scrutiny. Recent independent testing – by AECOM – of continuous flow hot water systems showed a clear advantage in terms of initial capital costs, as well as life cycle costs over 20 years, when compared with indirect stored and stored hot water systems.
The AECOM findings, after extensive deliberation, found that the brand’s continuous flow water heaters are 7.5% more economical than ‘traditional’ stored hot water systems.

Decentralised water heating saves energy and money, but it also offers flexibility. If, for example, a hot water store cylinder should burst or break down, the whole system is shut down – no more hot water until the problem is fixed. With a manifolded system one unit may be at fault but this doesn’t stop the whole system shutting down.

The problem of potential legionella proliferation is also better maintained in the design of a manifolded continuous flow system. In a continuous flow unit, 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 and because of this there is no requirement to heat a volume of water just to ensure the elimination of legionella. Another plus is, if demand grows, additional plant can easily be added in a modular fashion at a later stage if required.

In addition, smart controls can be added to commercial condensing continuous flow systems to boost and govern the performance of the hot water system.

Rinnai creates ‘system efficiency’ solution for longer life

Limescale can be a major contributor to a loss of efficiencies for water heating systems of any type, so leading continuous flow water heater manufacturer Rinnai has taken steps to maintain superior efficiencies throughout the life of the system by incorporating a proven limescale inhibitor that will significantly reduce the impact of limescale, thereby maximising efficiency over the product’s lifetime.

Rinnai has teamed up with electrolytic in line inhibitors, pioneers in limescale inhibitor technology, to maximise system efficiency on its range of A rated commercial water heaters.
This electrolytic scale inhibitor kit is for commercial hot water systems. Independently tested, it is a low-maintenance way to protect against the damaging and expensive impact of limescale on hot water systems.

Not only does it offer long lasting protection against the formation of hard limescale it also ensures bacteria has fewer places to hide as a result of cleaner surfaces, so in a secondary return DHW system the problem of Legionella is also heavily reduced. The independently tested and proven technology protects capital investment and occupier health.

The electrolytic zinc anode technology used in this solution is mentioned in the Part L Building Services Compliance Guide, whereas “external to pipe” water conditioning techniques are not.

The system’s low level zinc additions change the water chemistry to inhibit the formation of limescale by transforming calcite in such a way that they do not stick to the interior of the unit or pipework.

The system delivers value engineering as it does not decay after dosing and its effectiveness is not impacted by water storage or agitation caused by passing through a booster set.

Rinnai has recently supplied its system efficiency systems for London-based SGA Consulting, a specialist in low energy buildings, after liaising with the practice’s mechanical engineer Vivek Devan on two restaurant projects. Devan says “The Rinnai units are compact and their smaller footprint both physically and environmentally made them a good choice here. The scale inhibitor technology was also a factor.” Devan spoke with Rinnai technical experts before specifying the units and heard that Rinnai is actively promoting and selling scale inhibitor solutions following the successful results obtained from various trial sites.

The electrolytic unit may be installed in the rising main, before the water heater and booster set. Capex cost savings are probable because the rising main pipe size is often a smaller diameter than the hot and cold water distribution pipe sizes. Therefore, just one inhibitor system will treat the whole location, also offering an attractive value engineering opportunity.

The inhibitor is widely specified and installed in a range of sectors such as manufacturing, hotels, retail and supermarkets, healthcare and education as well as public authorities.

For buildings using BMS systems, a Pulse Splitter is an option that provides water flow rate or water usage data directly to the BMS from the water meter in the system.

The inclusion of the electrolytic system in Rinnai’s A-rated continuous flow water heating systems delivers peace of mind to installers and end users as performance is maintained throughout the lifetime of the appliances.

The scale protection units are available in a variety of pipe sizes – large 67,76 and 108mm; medium 28,35,42 and 54mm; and small 22mm.

Hot Water Heating Continuous Flow Systems shows dramatic savings – says independent report

A recent independent report emphatically concluded that continuous flow water heating systems have a clear advantage in terms of initial capital costs as well as life cycle costs over 20 years, when compared with traditional stored hot water systems*.

The study** shows that continuous flow water heating systems can be up to 7% more economical than equivalent ‘traditional’ stored hot water systems but that capital costs can be 41% less than indirect systems and a whopping 49% less than direct systems.

“In terms of maintenance you need to be realistic and not theoretical,” says Rinnai managing director Tony Gittings. “If a site has direct or an indirect system then it has to effectively shut down for maintenance. There’s no way around this problem. Not so with Rinnai continuous flow units as we cascade them together so that the demand for hot water can be met without closing down the whole site.”

AECOM, the world’s biggest building services consultants, was commissioned to carry out a totally independent life cycle study on continuous flow water heating systems, and to provide a comparison with conventional storage systems. Two case studies were provided on projects using continuous flow water heating systems.

AECOM then determined an equivalent storage based system for each case study and compared operational and capital costs.

For the life cycle comparison, the analysis period was 20 years, based on the expected service life. The net present value (NPV) calculation is based on a discount rate of 3.5% (The GREEN BOOK – HM Treasury), an inflation rate of 2% for servicing costs and projected retail fuel costs from DECC1.

In both case studies the continuous flow system showed a clear advantage in terms of initial capital costs, as well as life cycle costs over 20 years, with the continuous flow system consistently lower in energy use than the two storage systems.

Case study 1

This was a system for a typical, small, pre-fabricated fast food restaurant. It is assumed the system only serves the hot water demand.

The life cycle analysis includes the initial capital costs, projected annual fuel costs, and estimated annual servicing costs which are assumed to increase by 2% each year. The annual fuel cost assumes the same daily fuel consumption over the whole year.

The servicing cost is based on £130/year per boiler, and £160/year for a boiler and cylinder. The resulting net present values of the three showed that the continuous flow system is 6 – 7% lower than the two storage systems based on that 20-year analysis period.

Case study 2

This was a system for a shower block in a holiday camp, with six showers and four basin taps.

For the continuous flow option, the analysis is based on a configuration of 4 continuous flow water heaters that each have a nominal output of 48 kW, which, for this particular application, because there is a very short run of pipe work between the water heaters and the fixtures, it is possible for the water heaters to generate water at 40°C. The risk of legionella is overcome by the regular turnover of the system.

For the energy required to deal with the instantaneous hot water demand the analysis assumes that the bulk of the hot water demand would be due to the showers. Each shower would typically have a flow rate of around 9 litres per minute, which if mixed to 40ºC would equate to an instantaneous load of around 19 kW each, so even if there was only one shower running, the load on a single continuous flow water heater would equate to an efficiency of 95% based on the performance curve. As the hot water demand increases, the modular nature of this particular configuration would allow the 95% efficiency to be maintained for the bulk of the demand.

The difference in daily fuel costs between the three systems is around 7%. The usage profile for this case study is particularly suited to continuous flow systems (i.e. high but infrequent demand over the day), which is why there is an advantage in fuel consumption over the storage systems.

Systems employed in the study

* Indirect fired storage systems

This consists of separate heat source and storage cylinders, where for this study the heat source will be gas fired boilers running on 80ºC flow and 60ºC return with gross efficiency of 89%. As the hot water is stored at 60ºC in insulated cylinders there will be standing heat losses. The standby electricity is assumed to be 15W per boiler, and 60W when operating to cover fan and controls.

Direct fired storage systems

This is where the hot water storage cylinder has an integral gas burner to directly heat the water, and the key difference with indirect fired storage systems is that they are designed to operate in condensing mode and generally achieve gross efficiency up to 96%. A disadvantage of direct fired storage systems is that the standing losses are around 3 times higher than indirect storage cylinders.

Continuous flow systems

This is essentially a gas boiler that is designed to instantaneously heat mains water for supply directly to water fixtures without any storage. The key advantages with this type of hot water heating, is firstly saving in space needed for hot water cylinders and the associated standing heat losses. The challenge is that instantaneous hot water demand can vary hugely for most systems and therefore the continuous flow heating system needs to have a wide modulation range as well as maintaining efficiency over that range.

Rinnai Solo – a specifier’s and installer’s flexible friend

Infinity Solo condensing low NOX water heater is the first Rinnai product for the UK that combines the advanced technology of wall mounted continuous flow water heaters with a stainless-steel storage cylinder in one compact footprint.

When the product was first introduced Solo was adopted as a single installation product for light commercial operations such as small hotels and schools. However, Rinnai is now seeing greater penetration as installers are beginning to use them in multiples on larger projects – one installer has utilised three units for a major school academy installation.

It seems the market is identifying other areas for the Solo, beyond the target market of new build and refurbishment housing projects, where it is proving its worth in larger three/four-bed dwellings where one can expect to find a family bathroom, ensuite and a downstairs cloakroom/shower.

The Rinnai Solo is a versatile product – it is renewables ready so the business/building owner or householder can very easily extend the system to make fuel savings by adding solar thermal later. The 24kW-59.5kW Infinity Solo range is renewables compatible and supplied pre-fitted with a coil, meaning that the primary energy source can be renewable gains such as solar thermal, and the complementary Rinnai water heater will only apply the precise amount of gas to boost the difference in temperature.

Because the Solo cylinder is stainless steel it greatly reduces the weight compared to glass lined models, which makes transportation and installation much easier. As well as the difference in weight, the cylinders available also boast extremely low heat loss figures (as low as 1.41kW/h day), which means the customer pays less to maintain the heat within the tank and the system when fitted to a renewable heat source maximises renewable gains.

Rinnai’s new Solo range incorporates 35kW and 54kW appliances, ensuring that even sites with a smaller gas meter can utilise its advanced technologies. The larger Infinity Solo model will also act as a high-efficiency alternative to other forms of gas fired storage appliances.

Rinnai builds business with O’Neil’s

Rinnai, manufacturer of the Energysaver energy efficient range of gas fired wall heaters, recently pulled out all the stops in collaboration with Ayr-based installer O’Neil Gas Services to keep the congregation warm at St Mary’s Church in Saltcoats, Ayrshire.

O’Neil Gas Services with mission statement: ‘Big enough to cope. Small enough to care’ – is a family-run company founded by John O’Neil and now presided over by his son Brian O’Neil. It has 22 employees, 15 of them fully qualified Gas Safe registered engineers. The company offers domestic and commercial services covering the whole of Ayrshire, East Kilbride and South Glasgow and has four separate divisions – installation, service and repair, care and retail. O’Neil’s also operates a fireplace and bathroom showroom, designing and planning bathrooms from start to finish.

The O’Neil client list is impressive and includes NHS Scotland, North Ayrshire Council, Cunninghame Housing Association, SRUC Auchincruive Estate, Klin Holdings as well as various hotels, surgeries, churches and commercial businesses all over Ayrshire. More recently the company won the Irvine Housing gas maintenance contract for five years.

The company has built a reputation for quality, reliability and value ensuring that its 14,000 domestic and commercial customers return time and again for their gas and plumbing needs. They have retained thousands of customers, year after year, confirming the quality of their customer service.

O’Neil’s install Rinnai heaters for its commercial customers in a range of applications. “We choose Rinnai heaters because they are reliable, and easy to work on, as well as being efficient. O’Neil’s use only the best as call backs can be expensive and so installing the Rinnai heating range within commercial installations is an obvious choice, and makes for happy customers,” says
O’Neil’s installation manager Ross McWhirter. “We have used Rinnai heaters in many churches – for example St Mary’s – because of their efficiency and ease of installation.

“We have installed Rinnai continuous flow water heaters in Adeli Foods for the same reasons. We choose Rinnai products in such installations simply because no other product could provide the result we and more importantly our customers expect and want. This along with the excellent customer service provided by Rinnai, mean that their heaters and water heaters are always our choice.”

McWhirter first made the decision to go with Rinnai’s 1004T gas fired wall space heater for the St Mary’s Church, Saltcoats project and it is a decision he is pleased he made. “We used six Rinnai 1004T units siting them in the best location for effectiveness and for the convenience of the customer. The biggest part of the job was lifting the floors and running gas and electricity supplies to the units.

“Everyone I have spoken too at the Church since we completed the installation has said that it has never been as warm as it is now. The Church should also see a big difference in gas usage as the Rinnai units are more economical to run than the previous system.

“This was the first time we have used the Rinnai heaters and I was very impressed with the outcome of the job. They are very quiet while running and get the Church up to temperature very quickly,” says Ross.

O’Neil’s has the stamp of approval from Gas Safe to provide all gas services and has recently been awarded the prestigious ISO 9001, a certified management system for organisations proving its ability to provide services that meets customer’s needs. In addition, O’Neil’s has CHAS accreditation for its Health and Safety policies and PAS 2030.

Rinnai goes wild for Countryfile with Prestek

Rinnai, manufacturer of the energy efficient range of Infinity continuous flow water heaters, recently stepped in to ensure a recent BBC Countryfile event in the grounds of historic Blenheim Palace had a plentiful supply of hot water for its catering outlets.

Managing director for Prestek Services in Derbyshire, John Webster, no stranger to providing water for Blenheim Palace outdoor events, was called in to supply the means to provide hot water to the various catering operations dotted around the grounds.

Originally a kitchen and bathroom fitter, John has built a business providing water for events since first supplying a festival in 2001 and feels he has found his niche. “By its nature the events market is a small community so most of my work comes though word of mouth from relationships that have sometimes been 20 years building.” He believes the backbone to that trust is in providing reliable systems that work.

“I have used Rinnai hot water heating units for some time,” he says, “and believe they are the only ones suitable for this kind of work. They are a tried and tested solution. I first came across Rinnai units at an equestrian event around 10 years ago where they were being used for the mobile shower units. The customers loved them. Having seen the units in action I decided to purchase Rinnai for my own business.”

He explains that he has a fleet of hot water units that he can roll out whenever needed. “I have six Rinnai units running on LPG gas which are configured on to a T-stand, linked to the cold water supply and then linked to a sink in the wash-up area. It is an ideal arrangement for a temporary potwash area.”

At Blenheim Palace he was able to site individual wash up areas around the show area by linking them to a temporary system of pipework several kilometres long. “We simply had to build the network, link pipework and gas cylinders to the boilers, add a sink, and the caterers all had instant hot water.”

“All went well with no complaints from the caterers who had as much hot water as they desired. Which, let’s face it, is exactly what was required.”

The Rinnai units will never run out of temperature safe hot water all the time they are connected to a water supply. The burner lights automatically when the hot water tap is opened, and extinguishes when the tap is closed. Ignition is electronic so there is no pilot light. When the hot water tap is off, no gas is used.

As far as John is concerned for his kind of work he needs a product that is reliable, quick to set up and gets going with no worries. “Which is why we use Rinnai. You could say, they do what it says on the tin.”
