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.

Rinnai hot water delivery systems for large sites and demands

Rinnai offers a range of A-rated energy efficient continuous flow water heating systems that meet all user demand from the biggest sites-as well as reducing fuel costs, maintenance and minimising any possible downtime.

Large commercial building owners, in both public and private sector whether hospitality, healthcare, education or office buildings can benefit from fully modulating continuous flow water heating systems.

Independent comparisons on the Rinnai range showed 7% savings over the lifetime of the appliances (20 years) against certain traditional storage methods.

This follows another independent endorsement of Rinnai energy efficiency claims – ErP Energy Labelling. The ErP A-rating** the Rinnai models have achieved applies over the complete Infinity range – from small domestic models to XXL sized industrial units.

Rinnai is said to be the only manufacturer that can field a complete range of gas fired continuous flow water heaters that exceeds the demands of new legislation on fuel efficiencies and yield outstanding reliability throughout the life of the appliance.

An example of just one of the Rinnai units is the heavy duty condensing models (HDC), the Infinity HDC1600i. This premium condensing water heater which has been tested to below 20 ppm NOx, produces the lowest emissions on the market and has 107% net thermal efficiencies. The Infinity HDC 1600 renewables-ready low NOx series is the first heater of its kind to utilise Rinnai’s own patented pre-mix burner technology. The newly developed down-firing burner allows increased efficiency and reduces NOx gases. The Infinity 1600i low NOx series is available with an output of 58.4 kw producing 16.2 litres of temperature controlled hot water per minute (or 9.73 per hour) raised at 50°C.

The Infinity Plus solution for large commercial operations has been developed to provide never-ending hot water without costly storage and brings together multiple units of the company’s award-winning condensing continuous flow water heaters into single, easily manoeuvrable modules.

The comprehensive Rinnai Infinity PLUS range offers specifiers and end users a system that guarantees a constant flow of safe hot water at precisely the chosen temperature. Operated via an easy to use built-in digital controller, the water heater provides near mains pressure flow for as long as is necessary, without the need for thermostatic mixer valves. For large building operators who have stringent CSR conditions to fulfil, Rinnai hot water systems can help achieve targets.

For commercial buildings, Rinnai’s development and investment in integral smart controls compatible with sophisticated BMS Gateway compatibility allows easy monitoring to optimise the whole hot water heating system.

As for Legionella control, Rinnai has new technology for secondary return DHW systems where there is a pipework of cooling water that could possibly breed Legionella. This innovation comes in the form of a ‘little grey box’ inside which is both a timer channel programme and a temperature controller.

The ‘little grey box’ ensures the timer will over-ride the temperature control for a short period and then revert to safe levels. This combination 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 opens again, core temperature is back down to 42°C for safe use. It assists in eliminating risk from Legionella bacteria and scalding and is ideal for use in schools, office blocks and sports clubs to name just a few applications.

**In an ErP competitor comparison, the nearest competing brand to Rinnai Infinity units were also found to perform strongly in both XL and XXL load profiles. In the non-condensing product band the competitor could only produce a B rating for its XXL model while Rinnai scored A for its XL Infinity HD50i. It was the same story for the Infinity HD55i and HD55e XL units against the competitor’s corresponding XXL units. This is a defining key performance indicator for specifiers, installers and end users alike, giving confidence they are buying the best energy efficient kit available today.

Rinnai Solo has multiple advantages

The Infinity Solo condensing and low NOX condensing water heater is the first Rinnai product for the UK to bring together the advanced technology of its wall mounted continuous flow water heaters with a stainless steel storage cylinder in one compact footprint.

Originally envisaged as a single installation product for light commercial operations such as B&Bs, small hotels and schools, Infinity Solo is now being manifolded by installers for larger projects including a recent major primary school installation.

There is no restriction on the number of units that can be linked together as the installer can simply work out the volume of hot water required to determine the number of units required.

This versatile newcomer has also very quickly carved itself a niche in new build and refurbishment housing projects where it is being installed in larger three – and four-bed houses where specifiers have identified it as a cost effective hot water provider for a family bathroom, ensuite and a downstairs cloak room/shower.

Several of the 24kW-59.5kW Infinity Solo range are renewables compatible and supplied pre-fitted with a coil, ensuring 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.

The Solo cylinder is stainless steel, greatly reducing the weight compared to glass lined models, which makes transportation and installation a whole lot easier. The cylinders also boast extremely low heat loss (as low as 1.41kW/h day), which means the customer pays less to maintain the heat within the tank.

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 current forms of gas fired storage appliance. The cylinders also have extremely low heat loss figures (achieving 1.41kW/h day), which means the customer pays less to maintain heat within the tank.

Integral controls on the units ensure optimum performance and efficiencies whether locally or when integrated into a building management system. And there is also Legionella protection available too. Rinnai has invented technology for secondary return DHW systems in the form of additional controls which allow 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 Rinnai Infinity brand carries the widest range of condensing water heaters on the market today with the most impressive efficiencies in operation, leading the field in technological innovation.

Rinnai’s energysaver space heaters impress installers

Rinnai Energysaver fanned convection powered flue gas fired space heaters are designed specifically for use in large buildings where the range continues to expand its fan base.

Schools, community centres, libraries, conservatories and churches are all benefiting from the fast warm up of big spaces offered by the technically outstanding engineering of the Rinnai units with their low running costs.

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

The range has recently been enhanced with the addition of the Rinnai Energysaver 559FT, along with a makeover of the popular Energysaver 309FTR. The heaters blend effortlessly into the background in line with the style demands of modern interiors.

The Rinnai Energysaver 559FT offers an 88% reduction in energy consumption when the unit is on standby and has BMS functionality as an optional component making the appliance even more flexible.

The operation board is an easy to operate 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 benefits timer function and eco mode combined with the new unit’s ability to heat spaces fast, and the advantages of this super efficient appliance really do stack up.

The Rinnai Energysaver 559FT turns in efficiencies of 88% which is exceptional when you consider the effective heat generator seasonal efficiency required for UK building regulations. It has an input of 5.7kW and output of 5.2kW and the streamlined unit measures 582mm x 760mm x 257mm.

The Rinnai Energysaver 309FTR, like the 559FT, turns in net efficiencies of 85.9%. It has an input of 3.4kW and output of 2.92kW.The streamlined 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 from Rinnai is the Energysaver 1004T with its impressive input of 11.6kW and outputs 10.23kW. It measures 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 Energysaver 559FT the 1004T heater is suitable for BMS 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 building.

From the installer’s point of view the Rinnai Energysaver units are simple to deal with; there is no need for expensive (or extensive) ductwork, nor do they involve the necessity of running domestic heating circuits for radiators, or pipework to boilers. This cuts down drastically on cost and time on site.

Installers also report back that the tiny 80mm flue gives a neater finish on the outside of the building, a huge improvement on large flues and the correspondingly large holes that have to be knocked into the fabric to accommodate them.

Pete Seddon, Product Development Engineer at Rinnai UK, and a member of the technical team, explains that proven reliability and longevity have made the Rinnai range of space heaters popular over the 30 years they have been used in the UK. “They are so reliable,” he says, “they can easily last 20 years with no issues at all.”

“All models come with a 15-year warranty on the heat exchanger. This is a strong persuader for looking at the whole life costs of a new system, which well before the minimum 15 years life span is up should have more than paid for itself on energy savings.”

Rinnai has what is claimed to be the biggest range of water heating systems and units which are ‘A’ rated Energy Related Products (ErP).

Rinnai’s comprehensive range of ‘A’ rated continuous flow hot water heating units is said to be the largest currently available in the UK. ‘A’ rated Rinnai appliances range from Load profile (S) for domestic models to load profile ‘XXL’ for industrial units.

The Rinnai Infinity 11i interior unit weighs 16kg and consumes 6.10kW-21.60kW of Natural Gas and has an 11litre maximum flow rate. Integral controls on the unit ensure best efficiencies and market leading modulation ranges. Rinnai’s range of continuous flow gas fired water heaters includes heavy duty and condensing units engineered to produce the highest efficiencies and lowest running costs of any hot water heating unit. All Rinnai units meet and exceed all current and planned Building Regs and are A rated under new ErP regulations.

The Rinnai 11i combines many of these features as the applicable categories under load profile S making it perfect for domestic and light commercial applications. The 11i is rated ‘A’ for efficiency under ERP and comes with a 3 year parts warranty.

Because the non-condensing Rinnai 16i unit is less than 30kW output the unit is still compliant against the 2013 building regulations (proposal) which outlawed the installation of non-condensing units in new build projects from October last year.

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.
