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 keep-
ing 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 pre-
mium condensing hot water heater tested to below 20 ppm NOx,
producing the lowest emissions on the market, with 97% gross ef-
ficiencies.
Also in this established and proven range of award winning prod-
ucts 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 wa-
ter 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 com-
plete 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 sys-
tems 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 mas-
ter temperature setting made with the DIP switches within the heat-
er ensuring safety. Controllers can also deliver basic fault diagnosis.
Rinnai also fields a common header flue system to streamline mani-
folded 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 heat-
ing unit which combines the advanced technology of its wall mount-
ed water heaters with a stainless steel storage cylinder all in one.
And it boasts very low heat loss figures.
