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.

Use shutdown periods to treat heating systems, advises Sentinel Commercial

Water treatment specialist, Sentinel Commercial, is urging building maintenance engineers in the education sector to take advantage of planned shutdowns over the holidays to review water quality in boiler plants and implement any necessary chemical treatments, such as system cleaning and inhibitor dosing. These procedures, which can take several days or more to complete depending on the size and complexity of a system, are vital to the health of boilers and heating systems as a whole; those which do not receive adequate water treatment are likely to suffer from excess energy consumption, poor heat transfer, premature repairs and parts replacements, and breakdowns.

“Often, insufficient time is allocated for proper water treatment, and this can leave commercial heating systems vulnerable to a range of very serious and costly problems, including complete boiler failure and unexpected downtime. Shutdown periods represent the ideal opportunity for engineers to undertake programmes of best practice water treatment, thereby ensuring maximum protection and energy efficiency of those heating systems,” explained Chris Shelton, Sales Director of Sentinel Commercial.

Best practice water treatment, which comprises system cleaning, protection and maintenance, is able to deliver lifetime protection to boilers and heating system components through the prevention of corrosion – a phenomena which is otherwise inevitable. Limescale build-up (for systems located in hard water areas) can also be avoided. The benefits of best practice water treatment include optimal energy savings, heat transfer, and system longevity and performance, and meeting boiler warranty terms and conditions. Best practice water treatment is essential for both new and existing heating systems.

“Allocating adequate time for best practice water treatment is especially important when replacing boilers – works which are often planned during summer holidays – as the cleaning process to remove corrosion sludge, debris and other harmful foulants from older commercial heating systems can sometimes take a week or more. If it’s not undertaken correctly and contaminants remain in the circulating water, system performance, efficiency and reliability will remain poor. What’s more, the effectiveness of any subsequently dosed inhibitor will be compromised,” he said.

“On the other hand, the early application of a slower acting cleaner will facilitate a faster boiler replacement programme, ensuring that the existing system is cleaner and thus easier to work with.”

Water treatment shouldn’t just be limited to boiler replacements, however. Mr. Shelton advocates periodic assessment of system water quality using kits such as Sentinel SystemCheck to ensure adequate inhibitor concentration and cleanliness of system water. He says such checks, which are quick to carry out, not only evaluate the health and ongoing protection of a heating system but also help to identify any necessary maintenance and allow it to be undertaken in a convenient, controlled manner.

“Planned preventative maintenance is extremely important in the commercial and education sectors, helping to limit downtime and maintaining normal building operation. By regularly checking system water, engineers can catch potential problems early and take the time to consult water treatment specialists on the best courses of action – which could be carried out during planned shutdowns. Ultimately, this approach helps to achieve lifetime system protection and optimal energy savings,” he concluded.

New Evinox ModuSat® XR takes HIU efficiency to another level

Evinox has extended its best-selling range of ModuSat® Heat Interface Units with the introduction of the new ModuSat® XR and ModuSat® XR- ECO Twin Plate models. Providing both indirect space heating and domestic hot water, ModuSat® XR units are ideal for use in modern, efficient district and communal heat networks. All units deliver fast, dynamic domestic hot water response, and the ModuSat® XR-ECO models also provide ultra-low DHW return temperatures to the primary heat network.

With extensive experience in the design and application of HIU’s across thousands of UK-wide installations, Evinox has made significant advances in the performance of its latest range, aiming to help improve the overall efficiency of heat networks, whilst retaining high levels of user satisfaction and comfort levels.

ModuSat® XR – even faster, more efficient domestic hot water performance

An overriding requirement for many consulting engineers involved in the design and specification of heat networks, is to ensure abundant and responsive supply of domestic hot water. This goes hand-in-hand with residents expecting consistent and safe hot water at the tap. ModuSat® XR HIU’s deliver fast hot water without reducing the efficiency of the heat network.

“There is strong evidence that speed of hot water delivery is a key requirement for residents living in homes operating on communal and district heating schemes” comments Emma Alexander, Evinox Energy Marketing Manager. “The ability to be able to deliver abundant hot water quickly, while at the same time ensuring the efficiency of the heat network is not compromised, is a key challenge for heat network designers and HIU manufacturers, so the improved performance of the new ModuSat® XR range is an important step forward in this area.”

Evinox ModuSat® XR-ECO; how low can you go?

It’s clear that lowering system temperatures is a critical factor in the efficient operation of UK heat networks. Reducing the network primary flow & return temperatures enables heat generation plant to operate more efficiently; lower grade, low carbon heat sources to play a more predominant role in the energy mix; and network heat losses to be dramatically reduced.

ModuSat® XR-ECO units have been designed precisely with this in mind, incorporating ultra-high efficiency domestic hot water plate heat exchangers with improved volumetrics that encourage turbulent flow and optimal heat transfer.

These latest improvements mean designers are given the opportunity to focus on the energy efficiency performance of HIU’s and the wider heat network, with the confidence that units will continue to deliver impressive full load hot water capacity and flow rates.

A New Test Standard for Heat Interface Units from BESA

The ModuSat® XR has been tested under a new UK test standard, intended to help heat network designers to evaluate individual HIU performance on their network under typical UK conditions. The new scheme, operated by the Building Engineering Services Association (BESA), will provide HIU benchmarking, similar in many ways to the SEDBUK scheme for domestic boilers.

Evinox believes independent testing is an important step for the UK HIU industry, so the latest ModuSat® XR and XR-ECO models have been developed very much with these new standards in mind. Evinox is confident that this new standard will lead to HIU systems and heat networks being designed with efficiency as much as maximum hot water capacity being the key consideration.

New clean energy projects set to power 3.6 million homes

Eleven new energy projects worth up to £176m per year have been successful in the latest competitive auction for renewable technologies, the government has announced this week.

The projects, which are set to generate over 3GW of electricity, enough to power 3.6 million homes, demonstrate that the UK continues to be an attractive place to invest in clean energy.

The government is committed to investing in clean technology and driving economic growth as set out in our ambitious Industrial Strategy and upcoming Clean Growth Plan.

The competitive approach is continuing to drive cost reductions in the renewable energy industry – the cost of new offshore wind projects starting to generate electricity from 2022-23 are now 50% lower than the first auction held in 2015. The other successful technologies, Advanced Conversion Technologies and Dedicated Biomass with Combined Heat and Power, also achieved significant savings.

Competition has also driven down the costs for consumers. The capacity delivered in this auction cost up to £528m per year less than it would have in the absence of competition.

Projects are to be delivered across Great Britain from Wales to the Scottish Highlands and the West Midlands from 2021.

Minister for Energy and Industry, Richard Harrington, said “We’ve placed clean growth at the heart of the Industrial Strategy to unlock opportunities across the country, while cutting carbon emissions.

“The offshore wind sector alone will invest £17.5bn in the UK up to 2021 and thousands of new jobs in British businesses will be created by the projects announced. This government will continue to seize these opportunities as the world moves towards a low carbon future, and will set out ambitious proposals in the upcoming Clean Growth Plan.”

This investment will help the UK meet its climate targets while supporting jobs in Britain’s growing renewable industry. The UK has the largest offshore wind capacity in the world and low carbon businesses have a combined turnover of £43 billion, employing 234,000 people.

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.”

Win a Rinnai Continuous Flow Hot Water Heating Unit – worth over £1,000

RINNAI TO OFFER FREE UNIT TO LUCKY INSTALLER

Rinnai, manufacturer of the industry’s widest range of continuous flow gas fired water heaters, is showcasing its full range at the forthcoming INSTALLER SCOTLAND Show and is giving away FREE an 11i model – worth nearly £1000 retail – as just part of the attractions on its stand.

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.
