Radical™
Improves energy
efficiency and comfort
whilst reducing bills.
A radiator that produces
more comfort at less cost
A radiator that reduces
energy bills by up to 10.5%
Raising comfort levels with
more radiant heat
The power we use in buildings accounts for
40% of global consumption. And that has a
massive impact on the environment. But with
smarter energy management, our buildings
can emit up to 60% less CO2. That’s something
the European Union are moving towards, by
making energy consumption standards stricter.
Your choice of radiator determines how
comfortable the heating in your home feels.
And how much that comfort costs. You know
how a draught free room at 20°C can still feel
uncomfortable?
A radiator that delivers more heat, more
efficiently.
That’s why we’ve developed Stelrad Radical,
the energy saving radiator. It produces more
radiant heat than traditional radiators - saving
energy while raising comfort levels. At less cost
to the user, and to the environment. That’s a
Radical step forward.
•Thanks to the controlled flow of our unique
direct intake technology, the water in the
front panel reaches a temperature up to
50% higher than in a traditional radiator
•The Stelrad Radical energy saving radiator
reaches its maximum temperature 23% faster
than a traditional radiator
•It reaches its optimum performance level
while a traditional heater is still heating up
•After only 2 minutes it offers up to 50%
more radiant heat
Radiant heat heats up the room, furniture and
people, and is reflected back to create a more
comfortable feeling similar to the rays of the
sun. And standing in the sun always feels much
warmer, even if the surrounding temperature
is no higher than in the shadow - because it is
radiant heat.
At Stelrad, we believe the heating industry has
a major role to play, by developing systems
that work
so efficiently that they produce more heat at
lower temperatures.
•The energy saving radiant heat of the Stelrad
Radical will soon fix that. And with the
outstanding energy efficiency delivered by
its preset valve, it reduces your bills by up to
10.5%, too.
Domestic heating is usually based on
convection and radiation. With convection
heating, hot air rises from the heating
elements, cools down, descends via the wall
and is heated again. With radiant heating,
infrared radiation is sent directly around the
room regardless of airflows like wind or drafts.
•With higher radiant heat, the feeling of 20°C
can be achieved at a lower temperature
setting
The Stelrad Radical energy saving radiator’s
unique and innovative technology raises
comfort levels. And by working more
efficiently, it reduces energy bills - with a
saving of up to 10.5%.

Radical™
Up to 50% more radiant heat
means more comfort - at a
lower cost
These thermal images demonstrate the
improved radiant heat of the Stelrad Radical
radiator.
• In a traditional radiator the heat generated
consists, on average, of 80% convection
heat and 20% radiant heat - limiting the
feeling of warmth
• The Stelrad Radical energy saving radiator
increases radiant heat by up to 50%
The measurements show that the Stelrad
Radical energy saving radiator offers 1.5 times
more radiant capacity at 50% of the nominal
flow (which offers 90% of the nominal heat
output) compared to a traditional radiator.
So depending on the radiator size and type
it is compared to, the Stelrad Radical energy
saving radiator offers up to 50% more radiant
heat.
At 8 minutes,
with 50% of
nominal flow
Supported by a RIBA
& CIBSE CPD programme
CPD
Stelrad are certified as a member of the RIBA
and CIBSE CPD Providers Network. This means
we can provide RIBA and CIBSE approved CPD
material to architects and other specifiers. An
hour-long programme delivered by a member
of the Stelrad team delivers information on
every aspect of the Stelrad Radical
energy saving radiator and its application
Energy savings tested,
assessed and declared
by KIWA
Kiwa is a highly respected Pan European
institute providing internationally recognized
declaration services for systems and products.
As an independent expert, Kiwa also carries
out specialist testing, and the Kiwa Gas
Technology division has rigorously trialled the
Stelrad Radical radiator to assess and declared
its energy saving performance
Compatibility
The Stelrad Radical radiator is compatible with
the following:
• Gas boilers
• Electric boilers
At 8 minutes
with nominal
flow
• Solar PV
• Ground source heat pumps (GSHP)
• Air source heat pumps (ASHP)
So the comfortable feeling of a room at
20ºC is achieved at a setting of 1 degree less
(or even lower).
• Biomass installations
Test conditions: radiator K2, height 600mm,
length 1000mm, temperatures 70/55/20°C.

Radical™
A radiator that heats the
room, not the wall
Fully compatible with
renewable energy resources
Traditional radiators are as warm at the back
as they are at the front. So valuable energy is
wasted, as the heat goes into and through the
wall.
The Stelrad Radical
energy saving radiator is
perfectly suited for both
solo and multiple heating
installations.
It can be connected
to a modulating gas or fuel burner and is
compatible with all kinds of low temperature
systems, such as heat pumps, solar cells and
biomass installations.
The unique and innovative technology of the
Stelrad Radical radiator changes all that. The
flow connection to the front panel and the
return connection into the back ensures that
you feel warmer, faster.
And thanks to the higher radiation from the
front panel, the back panel is much cooler
than with other radiators. So up to 9% less
radiant heat is lost through the back of the
radiator.
That’s not just good for comfort levels. It also
means the heating system is more efficient,
which reduces bills - and CO2 emissions.
Less heat lost into the wall
Fast, convenient and
flexible fitting
Faster heating means less
CO2 - and lower energy bills
Higher radiant heat levels and front panel
temperatures combine with other benefits to
reduce bills and CO2 emissions.
Heating up fully in less time
Thanks to its unique flow pattern, heat up
times are dramatically shorter for the Stelrad
Radical compared to a traditional radiator.
Angle H Block
Hot water is directed into and around the
front panel. In a traditional radiator the water
flow divides in parallel to front and back panel.
2. Distribution of hot water
Radical radiator
Hot water rises in one water channel and
is distributed equally over the front panel.
A unique system then directs it to the back
panel where it is spread equally over the back
panel water channels.
Straight H Block with couplings
1. Directed flow
3. Faster heat up
Standard radiator
The front panel of the Stelrad Radical radiator
reaches a temperature of 62.5°C after 8.5
minutes. At that time, the front panel of a
traditional radiator is at 59.3°C. It only reaches
its maximum temperature after 11 minutes,
by which time the Stelrad Radical has already
been operating at maximum for 2.5 minutes.
Simple and quick to connect with
Hydro Block (H Block)

Radical™
Preset thermostatic valve
The thermostatic valve regulates the water
supply in the radiator. This valve is preset in
the factory according to the radiator’s size,
which guarantees optimum efficiency.
Simple and quick to connect
with Hydro Block (H Block)
Technical data
With the 3⁄4” male thread, the H Block’s
central connection means you can connect
pipes directly to the Stelrad Radical radiator
with additional couplers. This reduces the risk
of leaks and improves the installation speed.
• Valve stroke limiter
The H Block connects the radiator to the flow
and return pipe and has a built-in drain off
function, valve isolator and a lock shield for
ease of installation and servicing.
• Two H Block configurations are available:
with straight connections for pipes coming
from the floor or angle connections for
pipes coming from the wall.
Thermostatic head with
build-in sensor
• The H Block pack also includes a choice of
coupling pieces to connect the H Block to
the pipes - either 10mm or 15mm.
• Setting range 6°C to 28°C (43°F to 82°F)
• Setting numbers 1 to 5
Central connection
The connection coupling of the Stelrad Radical
is located in the middle of the radiator. This
means that the location of the connection no
longer depends on the length of the radiator,
so pipes can be laid down early in the project
with no need to know the size of the radiator.
• ❄Frost protection 6°C (43°F)
• Max. sensor temperature 50°C (122°F)
• Hysteresis 0.3 K
• Water temperature influence 0.7 K
• Differential pressure influence 0.3 K
• Closing time 24 minutes
Thermostatic label
Installers should order a completed unit based
on the appropriate H Block variation.
Left or right side valve
position
The Stelrad Radical radiator’s valve can be
mounted on either the left or right side
without having to adjust the supply and return
pipes. (K2 only).

Radical™
Radical mounting template
Using the mounting template for the bottom
connection of Radical radiators offers
important advantages during the installation,
e.g. leak testing the system without a mounted
radiator.
The mounting template replaces the radiator
during the installation, which reduces the total
installing cost. Finishing tasks such as painting,
tiling and applying wallpaper no longer require
the removal and remounting of the radiator.
The radiator is mounted after all the finishing
work, which guarantees a pristine condition on
commissioning.
The mounting template consists of a bridging
piece with 2 connections of 3⁄4” external
thread on a centre distance of 50mm. As the
wall distance depends on the radiator type, the
mounting template offers multiple positions
according to the available brackets.

be mounted before removal of
the bridging part, to eliminate any
possibility of pollution.

Stelrad radiators
are manufactured
under ISO 9001
quality systems in
the UK and every
one comes wrapped
in robust, practical
packaging that will
keep the product
pristine, right through
to installation. This
clever packaging
design allows
installation to be
completed prior to
removal.
Temperature table
For systems not operating at ∆t50 the
factors in the table below should be
applied. The output of a given radiator
can be obtained by multiplying the
quoted ∆t50 output by the operating
factor. Conversely, to derive a non ∆t50
output, divide the heat output required
by the relevant operation factor. This
‘∆t50 equivalent output’ can then be
used to select a radiator from the
standard tables.

Applications
Stelrad radiators are suitable for two
pipe installations.
For single pipe applications, it is
advisable to use diversion tees in the
pipework, as this will assist in obtaining
design performance from the radiators.
Although our radiators are suitable
for Microbore pipework, the back
tappings make them unsuitable for twin
entry valves.
Installation
Everything required for installation
can be found within each radiator’s
packaging. Brackets are of a strong
design, with open top and deep
slots, which facilitate easy and secure
installation. Plastic inserts seat the
radiator precisely on the bracket
minimising
expansion and
contraction noise.
The neat nickelplated plug and
vent provide
a watertight
joint, whilst
complementing the
superior finish.
To facilitate easy
one off replacement, nickel-plated brass
extension pieces are also available,
complete with sealing washer, in
20mm, 30mm and 40mm options.
Recommended height from the floor
to the base of the radiator is 150mm
minimum. This allows adequate airflow
when the radiator is placed on the
bracket.
Caution
When designing for domestic systems
we recommend that the Stelrad
radiators are only used in heating
systems complying with British Standard
Code of Practice for Central Heating for
Domestic Premises BS EN 12828:2003
and BS EN 12831:2003.
Single feed, direct cylinders are not
recommended as should interchange of
water occur, fresh aerated water would
enter the heating system, resulting in
corrosion.
Water treatment
On completion of the installation, the
system should be properly flushed and
filled in accordance with the British
Standard Code of Practice BS 7593:2006
for the Treatment of Water in Domestic
Hot Water Central Heating Systems,
Part L of Building Regulations and Good
Practice Guidance for Scotland.
After installation of a new Stelrad
radiator the central heating system
should be cleaned and flushed
with cleaner to remove existing
contaminants, flux residue and other
installation debris which, if left, can
cause damage to the new radiator.
Afterwards, treat the
system with an inhibitor to ensure
long term protection against corrosion
and limescale.
A comprehensive range of quality
chemicals including inhibitors, cleaners,
leak sealers and noise reducers that
protect and maintain central heating
systems can be obtained from:

Two coat paint process
Each Stelrad radiator is subjected to
a multi stage cleaning process before
the paint is applied. This involves
several rinsing stages, including an iron
phosphate and demineralisation rinse.
The first coat of paint is applied by
electrophoresis and the radiator is then
stoved and cooled. The second powder
coat in warm white (RAL 9016) is applied
and the radiator goes through a final
curing stage. It is then allowed to cool,
prior to packaging.
