WHY CHOOSE
GREEN HEAT?
We can no longer deny it:
the environment is suffering
because of our energy consumption.
We are all looking for smarter ways to manage energy. Buildings are big
consumers of energy and the majority of that consumption is for heating and
hot water, so our sector has a great responsibility to innovate. With renewable
energy and efficient heating and cooling technologies, our buildings can
emit up to 60% less CO2.
The European Union helps carry the load by gradually making energy
consumption standards stricter. And rightly so, because with a perfect energy
balance, a modern house uses less than a tenth of what was possible
30 years ago.
Modern heating technologies and renewable energy are crucially important
in order to achieve the ambitious objectives. To get the full benefits, such
technologies need low temperature systems. That’s where the green heat of
Stelrad ECO radiators comes in.

MORE RADIATION
= MORE COMFORT, LOWER COSTS!
Heat can be transferred in different ways: through conduction,
convection or radiation. Homes are heated mainly by convection
and/or radiant heat.
With convection heat, the air in a room is heated as air flows pass over heating elements.
The heated air rises, cools and falls again down the walls. The cooled air is then warmed up
again by the heating system.
In radiant heat, infra-red radiation is emitted to heat objects in the room directly,
independently of air flows such as wind or draughts. Radiant heat gives the entire room
including furniture, walls and people, a completely even temperature. These objects in turn
yield their heat to the room, making it feel very comfortable. The best example of radiant heat
is the sun. Standing in the sun, you feel the radiation on your skin, which immediately makes
you feel warmer, even if the nearby ambient air in the shade is not cooler than the air directly
in the sun. The only difference felt is the radiant heat.
The heat transfer from a traditional radiator is usually 80% by convection and 20% by
radiation. The comfortable feeling of warmth from solar radiation is therefore less present in
a traditional radiator, but the ECO radiator changes that. The photos below show that the heat
transfer by radiation increases significantly in the ECO radiator. Especially the greater amount
of radiation from the front panel is considered very pleasant.

These measurements show that, at a nominal mass flow of 50% (good for more than 90% of the nominal emission of heat),
the radiation capacity of the Type 21 and Type 22 ECO radiators increase by a factor of 1.5 compared with a traditional radiator.
Depending on type and height, the ECO radiator emits up to 50% more radiant heat.
The increased radiant heat is a direct consequence of the increased mean surface temperature of the front panel. An external test
laboratory performed exhaustive tests on the ECO radiators, with the results shown below.
According to the EN 12831 Standard, in practice there
are only a few days in a year (on average ten) on which
radiators use their maximum heat emission for a longer
period of time. ECO radiators provide additional benefits
even during these limited number of days of prolonged
full load.

The front panel of the ECO radiator has a mean temperature of
43°C after 2 minutes and 50°C after 3 minutes.
At the same times, the front panel of a traditional radiator has
mean temperatures of 28°C and 35.7°C respectively.

In this way, ECO radiators – without reducing
the perceived temperature – yield an energy
saving of at least 6%.

After the ECO radiator has stabilised (i.e. is in full load),
its front panel is up to 4% warmer than a traditional radiator.

Just like with the sun, the perceived temperature
with the ECO radiator is higher than with a traditional
radiator. In other words, at a constant perceived
temperature of 20°C, the increased radiant heat from
the ECO radiator allows the thermostat to be a few
degrees lower.
According to the BDH (Bundesindustrieverband
Deutschland), setting your thermostat a few degrees
lower means an energy saving of 6%.
Traditional radiator

An ECO radiator reaches a surface
temperature on the front panel that is up to
54% higher after 2 minutes and a higher final
temperature under full load, thereby emitting
up to 50% more radiant heat.
FASTER HEATING-UP PROCESS
LESS CO2!
In addition to more radiant heat and the higher mean temperature
of the front panel, there are various factors that reduce the energy bill
considerably if you choose an ECO radiator.
Thanks to its unique flow pattern, the ECO radiator’s heating-up time is significantly shorter than a traditional radiator’s.
1. The direct flow of water into the upward channel in the front panel. In a traditional radiator, the hot water first has to go through
a series of rising channels before it is spread over the front and back panels.
2. The further distribution of the hot water: the hot
water is spread evenly across the other channels
of the front panel. A unique system then takes it
to the back panel, where it is also spread over all
the water channels.

3. The front panel of the ECO radiator reaches its
maximum temperature of 62.5°C after 8.5 minutes.
At that moment, the front panel of a traditional
radiator is at only 59.3°C and its maximum
temperature is only reached after 11 minutes,
by which time the ECO radiator will have already
been at its maximum temperature for over
2.5 minutes.

FEWER LOSSES =
HIGHER EFFICIENCY!
By further limiting energy losses, the ECO radiator succeeds
in increasing the efficiency of the heating system even more.
58
Not only is the front panel hotter during the entire
heating-up process, even after stabilisation, but the
back panel is colder, which is just as important. Because
the back panel usually faces an outside wall, there is a
possible loss of radiation through the wall.

panel is 25.6°C, whereas a traditional radiator’s is already 35°C.
The ECO radiator’s values after 5 and 7 minutes are 37.6°C and
47.8°C respectively, whereas the results for a traditional radiator

In the case of the ECO radiator, there is a wide
difference in temperature between the two panels,
which can increase to over 12%.
TRADITIONAL RADIATOR
ECO RADIATOR
In a traditional radiator, there is hardly any difference in temperature between the front and back panels. The radiant heat is emitted
to the wall, and in the case of an outside wall, this heat is lost through it and energy loss occurs.
10
PRE-SET
THERMOSTATIC VALVE
The thermostatic valve is factory-set in the ECO radiator in relation
to the size of the radiator, which ensures optimal output and
efficiency.
In practice, optimal hydraulic setting of the heating installation is very important, certainly in view of rising energy costs.
The planner or architect uses software to correctly calculate all the necessary parameters (mass flows or throughput, couplers
and connectors, valve settings, etc.) for the hydraulic settings of the installation in new-build housing, which are then implemented
by the installer.
A lot of this information gets lost as time passes, and adjustments and/or repairs made in the meantime make finding the correct
settings in the event of restoration more complicated.
A more practically-oriented solution is to fit the radiators with a Kv pre-set valve in the factory. The principle is relatively simple:
the valve ensures that at a given pressure difference the correct quantity of hot water or mass flow passes through the radiator.
The proper pre-setting of the valve means that the radiator’s heat output is close to its nominal value. The valves in the ECO
radiator are set so that the throughput in the radiator is equal to or a little higher than the nominal throughput. A minimum of extra
throughput gives the heating system sufficient or a little more power, and the situation is brought close to its nominal or ideal state.
Increasing the throughput even more, which happens with an unregulated valve, gives relatively little extra power. This could cause
other radiators to get insufficient hot water and therefore be unable to heat the room.
The valves in the ECO radiator are in any case set
so that the throughput in the radiator is equal to or
a little higher than its nominal value. A minimum
of extra throughput gives the heating system
sufficient or a little more power, and the situation is
brought close to its nominal or ideal state.
11
Factory pre-setting is possible because radiator
dimensions do not differ infinitely. To be certain that small
radiators with a low heat output and limited water content
can be adjusted optimally, Stelrad has decided to use two
types of valve:
 a fine adjustment valve (Heimeier 4369 with a yellow
top) especially for small radiators.
 a standard valve (Heimeier 4368) with 4 different
pre-sets (white, red, black and blue) for normal
to large radiators.

Furthermore, Stelrad valves are continuously adjustable (with tapered groove), which means that the mass flow can be controlled very
accurately and there is less sensitivity to faults. This is in contrast to other valves that are difficult or impossible to align accurately and
can become clogged because of impurities (such as chalk) in the water, which leads to their working poorly and to insufficient heating
of the radiator.
Furthermore, if pump consumption is taken into account, then a heating system with factory pre-set valves can give additional
savings of up to 20% in the electricity the pump uses.
The benefits of pre-setting are considerable:
 time-saving during installation
 optimal water throughput in the radiator
 higher system efficiency as a result of lower return temperatures
The BDH (Bundesindustrieverband Deutschland) has shown that factory pre-set
valves have an extremely favourable effect on the hydraulic balance of a heating installation.
This gives energy savings of up to 6%
compared with non-balanced systems.

Art. 4368
Pre-set 8
The factory settings of the pre-installed thermostatic valves were determined on the basis of the following preconditions:
 heat output at 70/55/20 °C ( Dt = 15 °C )
 differential pressure Dp = 100 mbar
 control difference 1K
In case of abnormal preconditions, the valve can be adjusted manually and precisely (or be replaced if necessary) through
the presetting tables 4368 and 4369 (with setting key art. T1622).
In one-pipe systems the valve should be adjusted to position 8.

MORE SUITABLE FOR
RENEWABLE ENERGY
The ECO radiator can be combined perfectly with all types
of low-temperature systems such as heat pumps, solar panels
and biomass installations.
It can be connected to a modulating gas or oil-fired boiler and is perfectly suited for individual as well as collective heating installations.
Considering the limited number of days a year that a radiator has to operate at maximum heat output, partial heating with
a mass flow of 10-30% will be sufficient to heat a room during 90 to 95% of the heating periods. The radiator’s mean surface
temperature will be lower during these periods.
The desired room temperature will be achieved by a traditional radiator with a surface temperature of less than 40°C, but it will
not feel as comfortable. Thanks to its serial flow, the ECO radiator has a higher front panel temperature, which gives off up to
50% more radiant heat.
It is precisely this increased radiation that maintains a comfortable feeling, even at lower mass flows. This is extra important
when replacing an obsolete heating system that operates at high temperature with a modern system that operates at a lower
temperature and uses renewable energy sources such as heat pumps or solar panels.
ECO radiators are therefore perfect for use in heating installations that have been converted from a high-temperature
system to a low-temperature system such as heat pumps.
18
OTHER
BENEFITS!
As well as the unique qualities already covered, ECO radiators offer
many other benefits, for the end user and the installer as well as for
the wholesaler.
VALVE CAN BE FITTED ON THE LEFT OR THE RIGHT
The valve can be fitted on the left or the right of the ECO radiator without having to adapt the
return pipe. No separate part numbers, no separate stock, no extra price for a left-hand version,
and yet still the same short delivery time as for a radiator with the valve on the right.
CENTRE CONNECTION
There is a ¾” conical male Euroconus connection in the middle of the ECO radiator. This means
that the location of the connection no longer depends on the length of the radiator, with the
benefit that pipes can be installed at an early stage of the project without having to know the
size of the radiator. There is also an additional ½” female connection underneath at the right.
INPUT ALWAYS ON THE LEFT
The input on all multi-panel ECO radiators (T21, T22 and T33) has to be connected on the left,
irrespective of whether the valve is fitted on the left or on the right.
EASIER TESTING
Using our installation template enables the heating installation and the pipes to be fully
tested without the radiators having to be in place.
QUICK CONNECTION
The ¾” conical male Euroconus centre connection allows the pipes to be connected directly
to the ECO radiator without an intermediate coupler. This reduces the risk of leakage and
makes installation faster.
CONNECTION FACILITIES FOR RENOVATION AS WELL AS NEW CONSTRUCTION
This ECO radiator has an additional ½” female connection underneath at the right specifically
for the renovation market. This is in addition to the ¾” conical male Euroconus centre
connection that is often used in new construction projects.

OVERVIEW
Low temperature valve radiator with serial flow, centre bottom
connections and left or right pre-set valve positions
 Low-temperature panel radiator made from cold-rolled quality steel, with serial panel water flow (water flows first through the front
panel). This results in high energy efficiency, maximum radiation (even in low-temperature installations), fast heating-up process
and less energy loss on the wall side. Optimised in accordance with the requirements of EN442, EN12831 and DIN 4701-10.
 Quality assurance in accordance with ISO 9001. Heat output tested in accordance with EN442. Product quality certified by RAL.
FINISHING:
Upper grille and side panels
PRE-INSTALLED:
Pre-set Heimeier 4368 or 4369 valve insert , ECO air vent and blind plugs
VALVE INSERT:
The integrated adjustable valve (without thermostatic head) is factory-fit on the right side
of the radiator, CEN certified, tested in accordance with EN215 and compatible with
thermostatic heads M30 x 1,5 mm. For types 21 – 22 – 33 can the valve insert also be fitted
on the left side of the radiator, a left version for a type 11 radiator is available on request.
The thermostatic valve insert is factory-set in relation to the size of the radiator. This presetting ensures optimum throughput in the radiator. Factory setting for two-pipe systems,
also suitable for one-pipe systems (as long as the valve insert is adjusted to position 8).
