Introduction
Dunham Bush Evo-Lite is a radiant heating panel system for applications
where heat-output demand requires a cost-effective solution. It realises a
simple yet innovative design, utilising basic materials with proven
manufacturing techniques. The superior product finish is complemented by
lightweight construction and simple installation.
Authority
It is accepted practice and policy at Dunham-Bush to maintain exceptional
standards in engineering and quality. To this end, Dunham-Bush operates
a quality system and is registered as a firm of assessed capability
to BS EN ISO 9001 : 2000.
Description
Range
Evo-Lite radiant panels comprise aluminium alloy sheet finished in durable
coating, with an extruded aluminium channel bonded to the upper surface.
Copper tube (which transports the heating medium) is mechanically located
inside the extruded channel with special spring clips. Optional accessories for
hanging are supplied loose.
The main element comprises an aluminium sheet panel bonded to an extruded
aluminium profile for locating copper tube. LTHW or MTHW carried in the
copper tube gives up it heat, which is radiated from the aluminium sheet.
Insulation is fitted to the upper side of the panel to prevent heat losses
from the rear of the panel; the insulation is 50mm thick mineral wool,
fully-encapsulated in aluminium foil, factory-fitted and rated as a Class 0
material.
Evo-Lite typically weighs 9.8kg/m2; it is extremely lightweight, easy to handle
and install. Installation can be completed without the need for specialist tools
or training,

Application
General
Evo-Lite radiant panels are designed for a wide range of
applications, in particular hospitals, school classrooms,
assembly halls, residential care homes and offices.
Style CG (Ceiling Grid) panels can be fitted into a
suspended ceiling system with 600mm grid, positioned in
place of ceiling tiles.
Alternatively, style CS (Ceiling Surface) panels can be
fixed directly onto the underside of a ceiling slab or soffit.
Evo-Lite can also be mounted vertically onto a wall
surface. Style WS (Wall Surface) is used, which results in
higher heat outputs (see table 1 on page 6).
7
Any installation angle is possible. Evo-Lite can be fitted to
sloping surfaces, with the panel axis lying in any direction ;
manual vents are fitted to the highest point in the pipe
circuit. When the installed angle is greater than 10° to the
horizontal, style WS heat outputs should be used.
Comfort Conditions
It is recommended that for radiant heating systems,
comfort conditions are achieved when dry-bulb air
temperature is slightly lower than mean radiant
temperature. The combination of the two temperatures is
the dry-resultant temperature, upon which most comfort
conditions are specified.
Selection
The following guidelines are to assist the designer in
deciding the best layout for Evo-Lite:-
6. Expansion joints
Expansion joints should be fitted every 6m in a straight
panel run.
1. Heat loads
The total heat load of the room must be calculated in
accordance with recognised practice.
2. Panel run length
The total heat load should be divided by the total heat
output per metre, as given in table 1. This will then give
the require overall length radiant panels. Note that
vertical panels will give greater heat output, which
arises from greater convective heat transfer from the
panel surface.
3. Layout
Panel runs should be set out on a layout plan. Radiant
panels should be concentrated in areas of highest heat
loss i.e. around the outside perimeter of the room,
particularly, near windows. This will counteract
disproportionately high heat losses. Single or dual
circuit runs should be considered - see Water flow rates
and Hydraulic Resistances below.
7. Panel runs
Refer to page 9 for typical arrangements in a panel run.
If requested, Dunham-Bush will prepare complete
baseboard layout drawings for approval.
8. Water flow rates
To ensure rated heat outputs are achieved, water
velocity in the tube should be such the water flow is
turbulent. This maximises heat-transfer from the water,
through the tube and to the radiating surface. Water
flow rates should also be limited to inhibit noise and
erosion and high pressure drops. Water velocities
should ideally be between 0.3 - 1.0m/s.
9. Hydraulic resistances
Evo-Lite utilises 15mm OD copper tube to transport hot
water.To calculate the total pressure drop, determine
the water flow rate :Water flow
rate (kg/s)
4. Maximum mounting height
There is no maximum mounting height for Evo-Lite.
However, when mounting heights exceed 4m, the heat
load should be adjusted to allow additional losses of
radiant heat incident on walls, and stratification of air
which absorbs some heat by convection
5. Minimum mountint height
There is no minimum mounting height for Evo-Lite. For
comfort and safety the following rule of thumb can be
applied:Styles CG and CS
LTHW - minimum mounting height 2.4m
MTHW - minimum mounting height 3.0m
Contact Dunham-Bush for further information on
mounting heights and comfort conditions.

Construction
Handling
Style CG
The purchaser is responsible for off-loading. Radiant
panels are supplied ready for mounting with accessories
and insulation fitted separately. When a significant
quantity of panels is delivered, they may be palletised and
shrink-wrapped, so a fork-lift or similar of lifting equipment
is required. Radiant panels and accessories must not
dropped or suffer impact under any circumstances.
Panels are designed for suspension within a 600mm
ceiling grid; where the weight of Evo-Lite exceeds the
ceiling grid load limit, M6 drop rods or similar should be
used, with optional hanging brackets supplied by
Dunham-Bush. If panels are supported by the ceiling grid,
then safety wires should be fitted.
Style CS
Storage
Radiant panels should be stored in clean, dry indoor
conditions. Packaging should not removed until installation
takes place, unless damage in transit is suspected. Upon
receipt of product, the purchaser should examine the
panels promptly and any claims for damage will only be
accepted if, at the time of delivery, the consignment note
is endorsed with a note detailing the damage and
countersigned by the transport company.
Preparation
Style CG panels can be installed before or after ceiling
grids have been fitted. Styles CS /WS require suitable wall
or ceiling structure. The designer/installer should ensure
that fixings are suitable for the appllcation and provide
adequate support. Fixings and hangers are not supplied
by Dunham-Bush. Pipework to the panels should have
been completed as far as possible.
Installation
Reference should be made to a working layout or
services drawing, which shows how panels are arranged
and connections made. Please refer to Sitework
Instructions enclosed with the panels; further copies are
available on request.
Panels are designed for fixing direct to a ceiling slab or
soffit using end and connection brackets provided by
Dunham-Bush. End cover plates and connector cover
plates are used to finish panel joints and ends. Note that
additional braces or noggins may be required to match
panel fixing positions.
Style WS
Panels are designed for fixing direct to a wall using end
and connection brackets provided by Dunham-Bush. End
cover plates and connector cover plates are used to finish
panel joints and ends. Note that additional braces or
noggins may be required to match fixing positions.
Pipework Connections
Evo-Lite radiant panels are supplied with pipe-circuitry
complete; interconnecting panels are supplied with 15mm
compression couplings or expansion hoses, as required.
Pipework can be connected to the panel with solder,
push-fit or compression fittings; flexible hoses are
recommended to allow for rapid installation and flexibility.
