The decision was taken to upgrade to more energy efficient
condensing hot water heaters and incorporate the 500 litre
storage vessel to give the hospital a means of dealing with peak
hour demands. It is worth remembering that Part L of the Building Regulations
2013 set minimum thermal efficiency levels of 90% for natural
and 92% for LPG, consequently outlawing non-condensing gas
fired water heaters for use in new build projects.
The heating engineer contractors, A J Gastech, were given just
a 14 hour window in which to remove the existing system and
replace it with the new one. This was achieved with a bit of time
to spare, such is the expertise and professionalism of A J Gastech. Rinnai units and systems are now the number one choice for large
buildings and businesses with a heavy demand for constant hot
water or where high peaks of demand occur at certain times. Any
number of modules can be manifolded, so the water handling
capacity is truly infinite and there is no risk of the ‘cascade’ of hot
water ever running out.
A J Gastec Ltd provide plumbing and mechanical contracting and
maintenance for private customers, construction organisations in
domestic, commercial and industrial sectors. The company offers
services from installation to maintenance contracts with the
variety of works involving sites throughout the UK for both public
and private sector works.
Says Adam Stante for A J Gastech, “We are based in Bradford, the
heart of Yorkshire, and we have a dedicated team of specialists
that work throughout the UK, delivering high spec projects on
time and on budget. Our standards are of the highest quality, cost
effectiveness and to our client’s approval.”
The Rinnai HDC 1200i continuous model is for use on all high
demand sites as it is easily capable of delivering 2000 litres per
hour. It guarantees unparalleled levels of efficiency and hot water
delivery for the end user whilst streamlining installations and
guaranteeing future regulatory compliance.
This is a precision engineered water heating unit can also be
combined as multiple units into one single, easy to handle
module. Both HDC1200 internal and external models turn in a
market leading energy performance of 107% net efficiency and
offer superlative ranges of modulation as the system’s internal
analytical system can modulate the burner range from 54kw to
2.4kw. The Rinnai HDC 1200i is engineered for minimal energy
wastage and maximum energy performance.
The manifolded 1200i units can be delivered direct to site in one
complete, easy to manage package and at a very competitive
price. For the end user this guarantees considerable cost savings
over other forms of hot water generation. The relatively compact
footprint of all Rinnai units and systems means it can optimise
plant room space and safeguard accessibility for maintenance
and servicing.
There is huge potential for on-demand style water heaters such
as the Rinnai HDC 1200i units to play their part in new build and
in refurbishments where there are still many old systems that
need replacing as well as old-style gravity fed water systems that
use stored hot water.
The Rinnai Infinity HDC 1200i has lower greenhouse emissions
because of the new reduced NOx burner technology.
As Clifton Park Hospital has a secondary flow and return system,
complete range modulation is experienced ensuring that the
system is running at optimum performance at all times.
