Principle of operation
ELK 213 is an immersion heater intended for heating
systems and indirect heating of domestic hot water. The
immersion heater consists of a pressure vessel for an
operational pressure of a maximum of 3.0 bar (300 kPa).
Volume of 7 litres. The pressure vessel is made of construc-
tion steel 1 and is type approved by the National Swedish
Institute for Testing. The immersion heater is approved by
Semko according to protection class IP21.
The riser and return connections have male R50 threads.
When installing on double jacketed water heater type SPIS
(installation option 3, page 6), use the threaded flange.
Use the appropriate reduction sleeves for the other op-
tions. Flanges are available as accessories.
If necessary, the drain cock can be installed in the threaded
connection (R20 female) at the lower edge of the heater.
This connection can also be used a circulation connection.
The connection is equipped with a plug upon delivery.
Thermostat for immersion heater and isolator switch is op-
erated by knob on the front of the control panel.
The power can be selected in intervals, 13 – 11 – 9 –
7 kW, which eliminates unnecessary over dimensioning.
The immersion heater is connected to 9 kW upon delivery.
The power can be selected in intervals, 7 – 9 – 11 –

The immersion heater is connected to 9 kW upon delivery.
Note! This is an outline diagram. Actual installations must

Connection
Install the immersion heater so that external heating does
not cause overheating, for example, in front of the hearth
door (to prevent flames blowing out) or next to the flue
(to prevent damaging heat radiation). A suitable location
is normally at the side of the boiler, directly on the double
jacketed heater’s flanges or similar location.
The pipe installation must be carried out in accordance
with current norms.
The immersion heater is designed for upright installation.
For servicing, immersion heater replacement, miniature
circuit breaker or temperature limiter resetting as well as
draining, 200 mm of space is required in front of the heat-
er’s control panel and 500 mm above the heater (see fig.).
If the above stated spaces cannot be achieved, detachable
connections must be used.
Circulation pump must be used. Pipe dimensions can then
be reduced to R25 with welded sleeves. The immersion
heater can be installed in double jacketed water heaters of
the SP or SPIS type, see installation option 3, (self-
circulation is required).
For follow-up operation, it is recommended to install a
thermometer between the immersion heater and the ap-
paratus that is to be heated, so that the outgoing water
temperature from the immersion heater can be read off.
As the immersion heater is installed on the existing wood
boiler and is solely responsible for the heating demand,
the flue should be sealed. This is most appropriately done
using a plastic bag filed with mineral wool, stuffed into the
hearth, as well as a cover on the opening of the flue.
In closed boiler installations, one of the Swedish Work
Environment Authority’s approved safety valves must be in-
stalled in an open connection with the boiler’s (immersion
heater’s) highest part, however, not directly on the boiler.
The connection line must rise continuously. The safety
valve must be “exercised” regularly, at least 4 times per
year by being opened and closed again quickly. The pres-
sure is then reset by filling with water.
Pipe line between heater and open expansion vessel must
be routed upwards and must not be able to be closed.
Draining
The system is most easily drained by installing a drainage
valve at the lowest point on the pipe installation. Draining
through such a valve leaves a small amount of water in
the immersion heater, which must therefore be drained
through the rain connection (17). If the installation is nor-
mally drained through the immersion heater’s drain con-
nection, install a suitable drainage valve.
The pipe work must be flushed
before the immersion heater is con-
nected, so that any contaminants do
not damage the components parts.
Note!
Before draining the immersion
heater,
cut the power supply.
Note!

In the event of large hot water demands ELK-213, installed
on double jacketed water heaters, can be used to heat
domestic hot water. This is a favourable solution even for
hard water.
Recommended thermostat setting is 75 °C
Installation option 2

During electrical operation, AV1 must be open and AV2
must be closed. When the boiler is used, AV1 must be off
and AV2 open.
Installation option 4
VV
KV
AV1
When supplementing with the hot water heater, it is best
to equip the installation with shut-off valve AV1, which,
during the summer time, when the electric hot water heat-
er is solely responsible for the hot water supply, by-passes
the existing hot water coil. This prevents condensation and
increases the service life on the boiler.

FIGHTER 1110/1115/1120/1125/1130/1135 prioritises
charging hot water via the shuttle valve (VXV). When the
water heater/accumulator tank (VVB/ACK) is fully charged,
approx. 50 °C, the shuttle valve (VXV) switches from hot
water charging to the heating circuit. The heat pump is
then controlled by the outdoor sensor (OS) in combination
with the flow sensor (FS). The installed immersion heater
(ELK 213) is connected automatically when the energy
requirement exceeds the heat pump capacity. This option
can also be supplemented with a room sensor. This option
requires the accessories ELK 213, VST 11 and XTS 20.

SMO 10 controls heat pump, immersion heater, circulation
pumps, three way valves, etc. The heat pump works with
floating condensing against the heating system and priori-
tises hot water charging via the three way valve (VXV1).
If the heat pump does not manage the heating demand,
additional heat from the immersion heater is engaged.
When additional heat is engaged, hot water is heated us-
ing the immersion heater in the hot water heater.
In combined mode, the three way (VXV1) is open towards
the heating system.

Connection
Note! Electrical installations must only be performed by an
authorised electrician. Do not start connecting the immer-
sion heater without the permission of the electricity sup-
plier.
Standard supply on connection is 9 kW in two stages.
Connection to another output is made at the top of the
immersion heater, directly on the immersion heater’s con-
nections and on terminal block (8) in the connection area.
All electrical equipment is ready connected internally and
the power supply is only on terminal block (1). Connect
the cable for any circulation pump to terminal block (8),
fused with a 10 A miniature circuit breaker and routed
through special strain-relief.
Upon delivery the immersion heater has three unopened
cable grommets. These are for supply, external control,
pump, and load monitor.
The immersion heater is equipped with a time relay (9),
which blocks part of the immersion heater via contactors
(10) so that a maximum of 6 kW is connected the first two
hours after the immersion heater has been disconnected.
By short-circuiting pins Z1-Z2 on the time relay (see fig-
ure) the immersion heater can produce full power without
waiting two hours.
Z2 Z1
The immersion heater’s output can be changed to 7 – 9 –
11 – 13 kW. Post connection is carried out on the immer-
sion heater as well as in the relevant block (8).
Output can be controlled in three stages in all outputs and
in two stages for outputs 7 and 9 kW. Outputs 11 and 13
kW must not be controlled in two stages. Change-over oc-
curs on terminal block (8).
Marked cables for change-over on terminal block (8) are
supplied in two bags.
Supply on connection is 9 kW in only two stages.
Zero from supply is connected to N2 on terminal block (1)
With accessory XTS 20, ELK 213 can be controlled exter-
nally from FIGHTER 1110 / 1115 / 1125.
With accessory AXC 40, ELK 213 can be controlled exter-
nally from F1145.
ELK 213 can be controlled externally from FIGHTER 1120 /
