8 Modification to clause 9, "Room heating capability"
Modify title as follows:
Room heating capability and heat output
Replace:
9.1 Heating capability
The capability of the storage heater to heat the room is determined.
NOTE 1 The room heating capability of a storage heater is dependent on the energy which can be
discharged at a particular level of heat output.
NOTE 2 A method of determining the size of a storage heater suitable for a particular room is given in
Annex C.
The storage heater is placed in the calorimeter described in Annex A with its front facing the
air outlet and is operated for 24 h. The charging control is short-circuited and the appliance is
charged in the minimum discharge condition until the energy consumed equals the continuous
charge acceptance measured in 8.1.
The charging supply is switched off and the appliance is operated in the maximum discharge
condition until a total period of 24 h has elapsed.
The heat output in kilowatts is measured throughout the cycle of operation and the results
expressed as shown in Figure 1. The energy discharged by the storage heater during any
period is calculated by integrating the heat output with this period.
The heat content ηmax of the storage heater at the end of the charging period is calculated as
the difference between the continuous charge acceptance and the energy discharged during
this period.
The heat content at any point in time during the period of operation in the maximum discharge
condition is calculated as the difference between ηmax and the energy discharged during this
period. The heat content is expressed as a function of time as shown in Figure 2.
The room heating capability at any point in time is dependent on the energy discharged during
the period of operation in the maximum discharge condition and is expressed as a function of
the heat output as shown in Figure 3.

9.2 Maximum heat output
Method A: The test of the heater according to sub-clause 9.1 is done. After the charging supply
is switched off the appliance is operated in the maximum discharge condition.
The integrated measured heat output within the first hour divided by the 1-h time interval is
stated as the maximum heat output of the heater in kW rounded to the next 0,1 kW.
Method B: An approximate method can be used to determine the maximum heat output without
calorimetric test chamber of Annex A.
In this case the heater is operated in a normal environment according to the conditions of 6.2.
First the heater is charged as in the test process of Clause 9. After first charging when the
charging supply is switched off the appliance is operated in the maximum discharge condition
for 2 h or for the charging control reset time, whichever is longer. After this time another
charging process is started till the integrated charging control switches off. During the charging
process the heater is set to the state of minimum heat emission and the duration of heating
and the energy supplied to the heater is recorded. This recharging process is repeated 3 times
in total. For each cycle the supplied energy is divided by the total length of the cycle (charging
time + discharging time). The minimum of the results from the 3 cycles can be declared as the
maximum heating capacity. The value has to be given in kW rounded to 0,1 kW.
NOTE As Method B is an approximation the results will be in the region of 20 % lower than results
obtained using Method A.
9.3 Nominal Heat Output
The continuous charge acceptance as defined in sub-clause 8.1 is divided by the discharge
period of 16 h.
NOTE The nominal heat output is only an indicative value and it is advised not to use it for heating
demand calculation. The heating capacity is also influenced by the charging periods available.
9 Modification to clause 10, "Heat retention"
Modify title as follows:
Heat retention and maximum storage capacity
Replace by:
10.1 Heat retention
The ability of the storage heater to retain heat is determined.
The test of Clause 9 is repeated except that the storage heater is kept in the minimum discharge
condition throughout the test and the test period may be different from 24 h.
The heat output is measured throughout the cycle of operation. The energy discharged by the
storage heater during a discharge period of 16 h is calculated by integrating the heat output
during this period, commencing when the charging supply is switched off.

10.2 Maximum storage capacity Q
max
Method A: The test of the heater according to Clause 9 is done. At the end of the charging time
the difference of the continuous charge acceptance and the integrated amount of heat output
till the charging supply is switched is calculated. This difference value rounded to the nearest
0,1 kWh is stated as the maximum storage capacity.
Method B: An approximate method can be used to determine the maximum storage capacity
without calorimetric test chamber of Annex A.
In this case the heater is operated using the test procedure of Clause 9 or according to the
instructions of the manufacturer on how to achieve maximum charging level, then the heating
elements are switched off. The stored amount of heat is calculated by measuring the mass and
the average temperature value of the storage material (recorded 10 min after the end of the
charging process).
Q =0,9⋅(Storage _ mass⋅⋅T _ av Cp _ av)
max
NOTE 1 It is essential that only dedicated storage material is considered for Storage_mass. Parts from
housing and other functional components will not be included.
NOTE 2 To determine the average temperature, it is important that a sufficient number of
thermocouples is placed at or inside the storage material.
NOTE 3 The specific heat capacity of the material Cp_av is the average of the temperature dependence
heating capacity. The average is taken from Cp values at same temperature intervals, with a maximum
of 200 K for the temperature intervals. E.g.: Cp_av = Average {C _ , C _ , C _ , C _ }.
p 20C p 200C p 400C p 600C
NOTE 4 As Method B is an approximation, the results will be in the region of 20 % lower than results
obtained using Method A.
10 Modification of clause 13, "Stability of room temperature"
Modify first three paragraphs as follows:
The amplitude and drift are determined for storage heaters incorporating a room temperature
control.
The heater is placed in the chamber of a climatic test room as specified in Annex B. The heat
loss of the chamber is adjusted to a value of 1,2 times the maximum value of the heat output
determined during the test of Clause 10, the temperature of the chamber being 20 °C.
NOTE 1 These conditions can be achieved by placing a direct-acting heater in the chamber during
preparation and then removing it when the test begins.
NOTE 2 The factor 1,2 is used to make sure that the room temperature control operates.
The appliance is fully charged according to 8.1 and then placed in the chamber, the room
temperature control being adjusted to give an average temperature in the chamber of
20 °C ± 2 °C.
11 Addition of clause 15, "Requirements to comply with functions
according to the ecodesign regulation"
Add the following new clause 15.
15.1 General
Functions implemented in electronic controls which are used identically in a family of heaters
have to be tested only for one member of the family.
