The Quantum Cylinder
This graph illustrates the energy storage capacity of
the Quantum Cylinder across a range of temperatures.
Energy Storage Capacity Water Cylinders
This graph illustrates the standing heat loss of a range
of Quantum Cylinders against a range of references.
Cylinder Heat Loss Comparison
Notes
• Creda Quantum values measured for direct electric cylinder
in accordance with EN12897 at a temperature difference
between water (65°C) and ambient (20°C) of 45K.
• CHeSS standard and best values in accordance
with central heating system specification CE 51 2008,
and Energy Saving Trust publication.
• Red Jacket calculation based on 80mm bre glass insulation.
• Spray foam cylinder heat loss data taken from competitor
product range. The stated insulation thickness is 35mm.
• It should also be considered that cylinder replacements are
covered under Part L1B of building regulations (conservation
of fuel and energy). Part L1B refers to the Domestic Building
Compliance Guide which calls for cylinders to have a heat loss of
no more than the high level products as specified in CE 51 2008.
