How to install and
use your storage heater
Storage Heaters NST.M and NST.A
Introduction
This manual
First of all, we would like to thank you for having bought an EV product; one that we
hope will give you years of reliable heating.
Before installing the heater, please read the following instructions carefully. EV is not
responsible for any damage or problems resulting from incorrect installation. Once
your heater is up and running, please store this booklet in a safe place for future reference.
Recycling
When you no longer need this heater, please follow the European Directive 2002/96/
CE as regards its disposal. This storage heater can not be put out as normal rubbish.
It must either be taken to a special tip or to a distributor offering to do this for you.
Recycling electrical appliances separately allows component parts to be re-used and
limits the damage to the environment that would otherwise occur. Recycling saves
power and resources. To encourage this, the heater bears a symbol showing it can not
be put in a normal bin. For further information, get in touch with your local council or
the shop where you purchased this product.

How to Use your Heater
1. Turning your heater on
Getting started
We recommend that when you use your heater, for the ﬁrst couple of times, that you
keep the area well ventilated. The heater is likely to give off a slight odour from its time
in storage and carriage. This is perfectly normal and will disappear almost immediately.
Never cover the heater’s grille, nor use it as a storage shelf. In particular, keep inﬂammable materials such as newspapers, magazines, wood and material away from the heater. Similarly, do not obstruct the bottom of the heater in anyway as this will prevent air
from circulating within it.
As the heater ﬁnishes charging and starts to release its heat, it becomes hot to the
touch, particularly the grille. These temperatures are within electrical heating norms
and will not cause injury if touched momentarily.
2. Controlling your heater
2.1 Input
The storage heater charges up automatically. The thermostat will turn it off when it
reaches the temperature you choose. You will ﬁnd the control dials on the right-hand
panel. Simply turn the dial to one of the four positions below to change the charging
process:
• Your heater is turned off and will not charge up.
1 The heater charges over night on this minimum setting.
2 Half-capacity. The heater charges at 50% of its full capacity.
3 Full-capacity. The heater is totally charged. This is the ideal setting for the coldest
times of year.
We would advise you to take into account where you live, as well as the time of year,
when choosing the correct setting.

How to Use your Heater
2.2 Output
A dual-heat source
This model of storage heater provides heat in
two ways: a) through its panels, like a radiator
and b) like a convector heater – ﬁlling the
room with its warm air ﬂow via its grille.
A standard safety feature, found in all such
heaters, prevents the convector element from
working when the heat released would be
sufﬁcient to cause injury. As a result, just after
the heater is fully charged, usually in the early
hours of the morning, the output controls
will not allow the grille to be used. Were this
feature not to exist, the airﬂow would, at this
point, be hot enough to either scald or burn.
[1]
The output and input dials are to be found on
the right-hand side panel of the storage heater. Both have clear markings and large
numbers that indicate the settings chosen.
As with charging, there are four positions to choose from when deciding what output
you want.
• The storage heater is working by radiating heat and the grille is not in use at all. As
a result the storage heater maintains its heat for longer. This is the best option for
those people wanting to turn on the convector and use up the heat left at the end of
the day.
1 The storage heater gives out the minimum output through the grille.
2 The storage heater gives out average heat via the grille.
3 Maximum convection output. This setting only kicks in when the heat of the
airﬂow does not present any risk. Even so, the output takes places quickly and there
will only be heat for the ﬁrst part of the day.
As with charging, you will need to ﬁnd the level of output that meets your needs and
takes into account where you live.

How to Use your Heater
2.3 Automatic Controls
(Only available in the NST.A model)
The automatic version of the NST.M is called
the NST.A. It is identical to the NST.M in
terms of design and performance but has the
additional beneﬁt of a thermostat. The dial
that controls this, is also on the right hand
side of the heater, below the output and input
dials [2]. The thermostat itself is in the base
of the storage heater, where it registers the air
temperature as it enters the heater. When this
matches, or is higher than, the preset one, the
recharging cycle is turned off.
The automatic dial gives you three settings:
Manual – the storage heater charges as
normal.
Automatic – charging depends on the
room temperature. When this is more
than 20°C, the storage heater will not
recharge.
[2]
Frost-protection – the storage heater switches itself on when the temperature
drops below 6°C.

How to Install
2. Prior to Setting Up
To make handling easier, the heater and the bricks come separately.
You will ﬁnd the stand next to the elements, inside the heater.
A qualiﬁed electrician should install the heater.
It is illegal to install this storage heater in workshops where there are gas fumes or any
inﬂammable products.
It is advisable to position the heater a certain distance from other objects, in
particular doors and wooden furniture. Minimum distances to other objects are:
The electrical connection in the fuse board must be through a single phase circuit
breaker. This will ensure the necessary minimum distance of 3 mm between contacts.
The working voltage is 220/240V and must be earthed.
The electrical installation should meet all electrical regulations.
The wall you put the heater on must be sufﬁciently strong to take its weight, as should
the ﬂoor. If you have any doubts, talk to a surveyor.
Make sure the room and where you are siting your storage heater is clear of all dirt and
dust.

How to Install
3. Step-by-step guide to assembly
3.1 Fixing the Heater to the Wall
Take the storage heater out of its packaging with care. Instructions for doing these can
be found the packaging itself.
You will ﬁnd the feet inside the heater.
Undo the bottom screws [4]. Remove the front panel [5]. You will now be able to see
the storage heater’s core and the ﬁxings for the grille. Now remove the front panel of
the storage core by undoing the screws to ﬁnd your storage heater’s feet.
The feet simply click into place. They do not require screws. Place the heater upside
down, and clip the feet into place. Check they are secure and turn the heater upright
and place into position.
To ﬁx the storage heater to the wall, remove the front grille. This comes as a single
piece, designed to make installation easy. It also means that in the future, replacing
the grille, should it be necessary, is straightforward. You unscrew the grille [7], sliding
it out as shown [8].
[4]
[5]
[6]

11
How to Install
Place the storage heater against the wall where you want to put it and using a pencil
mark where the brackets will go [9]. Move the storage heater to one side. Drill the
necessary holes and ﬁx the heater in place.
[8]
[9]
3.2 Charging the storage blocks
At point 7 “Element distribution”, you can consult the number and brick
distribution per model.
Be careful when placing the storage heater to leave sufﬁcient space on the right
hand side for easy access to the dials [10]. Pull the elements towards you and place
the blocks behind them. Return the elements to the upright position, and place the
remaining blocks in front of the elements. These blocks match those behind [11].
Check you have the blocks in the correct position. Each block has an arrow showing
how it should be placed.
[10]
[11]
3.3 Connecting the heater to the electricity supply
Look at the bottom right-hand side [12]. Unscrew the bottom screw of the electrical
connection strip [13] . This can now swing forward, making connecting the cables very
straightforward.
Pass the electricity cable from back to front, as shown, [15] and connect up in accordance
with the wiring diagram provided (see point 4).
Screw the connection strip back in place.

3.4. Final Checks
Before putting the front panel of the otorage heater back on:
· Carry out an insulation test with a voltage of at least 500 V. The insulation resistance
must be 0.2 MOhm
· Test that the elements work and that they also stop when the input thermostat is
turned .
· Connect the heater and check consumption, tension and intensity, using the
following diagram as a guide.
· Finally, check that all the panels ﬁt properly and that the clips [16] are securely in
place.
