Manufacture
Cylinders and combination units are manufactured from copper sheet to BS 2870; joints either are autogenously welded
or brazed with zinc free alloy and screwed connections are of copper to provide total immunity to dezincification.
Cylinder tops and bottoms are produced to ver y close tolerances, guaranteeing metal thickness, both before and after
forming, in accordance with the requirements of the vessel standards.
Every cylinder is pressure tested to 1.5 times its working head.
Finally each product is coated with urethane foam insulation or alternatively sprayed with a 'permanised' copper finish
to retain its appearance and resist tarnish.
All cylinders are Part L compliant.
Thermostatic Control of Hot Water
It is essential that cylinders are fitted with a thermostat in order to conser ve energy when design water temperature
is reached. Generally 60°C is accepted as being an adequate temperature for most domestic purposes. 65*C should not
normally be exceeded as a storage temperature.
a) Direct Cylinders
A thermostat is usually incorporated in electric immersion heaters and gas circulators.
b) Indirect cylinders
The thermostat should be fitted approximately one third the way up the hot section of the unit and, ideally,
should control the operation of the boiler and pump.
Insulation
Building Regulations require all hot water storage vessels to be insulated. BS 1566 and BS 3198 allow maximum heat loss
for factor y applied insulation of 1 watt/per litre of hot water storage capacity under test conditions. Range cylinders comply
with, or improve on this minimum performance requirement.
Physical Properties
Range blue urethane foam meets the insulation material requirements of British Standards and is covered by the 'Kitemark'
certification of the cylinder.
A mixture of components in liquid state are sprayed onto the surface of the copper and reacts within seconds to form a low
density foam coating firmly attached to the copper to ensure a perfect permanent fit.
Range blue foam lagging retains its original thickness and insulation properties throughout its life. In addition
to its thermal qualities, it protects the cylinder against dents and more serious damage during transit, storage
and installation.
Installation Notes
The rate of flow from a hot tap is influenced by pipe sizing and layout but is principally dependant upon the height of the
feed tank above the tap, in a normal installation the water level in the cold cistern should be a minimum of one metre above
the highest hot tap with sufficient space between the top of the unit and the ceiling to ser vice the float operated valve
(ball valve). It is important to adjust the float operated valve to correct the water level at the marked water line on the side
of the cold feed cistern.
Ozone Depletion
Range blue lagging is CFC-Free, HCFC-Free and has an ozone depletion potential of zero.
