Ta evropski standard se uporablja za plinske gospodinjske naprave za pripravo tople sanitarne vode. Uporablja se za sorpcijske toplotne črpalke, ki so priključene na rezervoar za toplo sanitarno vodo ali ga vključujejo. To velja za vse naprave, ki so na trgu na voljo kot samostojna enota ali kot paket in vključujejo:
– en sam plinski gorilnik za toplotno črpalko in/ali dodatni plinski gorilnik za največjo obremenitev;
– toplotno moč plina, ki ne presega 70 kW;
– rezervoar za toplo vodo s prostornino, ki ne presega 500 l.
Standard EN 13203-1 v kakovostnem in količinskem smislu določa zmogljivost za pripravo tople sanitarne vode za različne izbrane namene. Zajema tudi sistem za predstavitev informacij uporabniku.
Ta dokument določa metodo za ocenjevanje energetske učinkovitosti aparatov. Določa število dnevnih ciklov izpuščanja za vsako uporabo gospodinjske tople vode, kuhinjo, prho, kad in njihove kombinacije, skupaj z ustreznimi preskusnimi postopki, za omogočanje energijske zmogljivosti različnih plinskih naprav za primerjavo in uskladitev s potrebami uporabnika.
Kadar cikel sorpcijske toplotne črpalke ne deluje za pripravo tople sanitarne vode v poletnem obdobju, se za ocenjevanje energetskih lastnosti ne uporablja ta standard; uporabiti je treba standard EN 13203-2.

If liquid heat transfer media other than water is used, the specific heat capacity and density of such heat
transfer media shall be determined and taken into consideration in the evaluation.
When the gas-fired sorption heat pump combined with a gas-fired appliance does not operate in heat pump
mode for domestic hot water production according to data in Table 1, the test shall be performed according to
EN 13203-2 instead.
For all tests defined by this standard, the same adjustment of the appliance shall be maintained.
4.4.2 Test room
The package shall be installed in a well-ventilated, draught-free room (air speed less than 0,5 m/s).
The package shall be protected from direct solar radiation and radiation from heat generators.
If the package incorporates an air source outdoor heat exchanger a further test room is needed. The size of
this test room shall be designed to avoid any resistance to air flow at the air inlet and air outlet orifices of the
test object. The air flow through this room shall not cause any short circuit between the two orifices, and
therefore the velocity of air flow at these two locations shall not exceed 1,5 m/s when the test object is
switched off. The air velocity in the room shall also not be greater than the mean velocity through the unit inlet.
Unless otherwise stated in the technical documentation, the air inlet and air outlet orifices shall not be less
than 1 m from the surfaces of the test room; this also applies to any measuring ducts.
For sorption heat pumps separated from the storage tank, the liquid flow rate has to be set on the liquid outlet
side of the heat pump to the nominal flow rate specified in the installation and/or operation manual.
The sorption heat pump and/or package shall be installed and connected for the test as specified in the
installation instructions.
Temperature and pressure measuring points shall be situated in order to obtain significant mean values.
Set points for internal control equipment of the unit such as thermostats, pressure switches or mixing valves
shall be set to the values stated in the installation and/or operation instructions.
Air and entrained gases shall be removed from all water and other heat transfer liquid systems.
Each water pipe shall be installed in accordance with the installation instructions to the maximum stated
length or 5 m whichever is shorter. Thermal insulation shall be applied to the pipes in accordance with the
installation instructions.
4.4.3 Water supply
For the tests:
— the domestic water pressure is the static inlet pressure under dynamic conditions measured as close as
possible to the appliance;
— the inlet and outlet temperatures of the domestic water shall be measured in the centre of the flow and as
close as possible to the appliance.
The inlet temperatures are measured immediately upstream of the water inlet connection. Except where
otherwise stated, the outlet temperatures shall be measured immediately downstream of the outlet connection
or, in case of an appliance with spout delivery, by means of an immersed temperature measuring device, e.g.
a u-tube fitted at the outlet of a tube of the same length as the minimum length of the spout normally supplied
together with the appliance.

prEN 13203-6:2015 (E)
The hot water temperature shall be measured with a rapid response thermometer:
"Rapid response thermometer" means a measuring instrument with a response time such that 90 % of the
final temperature rise, from 15 °C to 100 °C, is obtained within about 1 s, when the sensor is plunged into still
water.
4.4.4 Steady state
Steady state operating conditions shall be regarded as established when the appliance operates for sufficient
time to reach thermal stabilization. The steady state is reached when the water temperature at the outlet does
not vary by more than ± 0,5 K.
NOTE This condition can be reached with a gas which is different from the specified test gas, provided that the
appliance is supplied with the specified test gas for at least 5 min before the requirements are verified.
4.4.5 Initial adjustment of the appliance
The appliance shall be installed in accordance with the installation instructions.
The heat input shall be adjusted to within ± 2 % of the nominal domestic hot water heat input.
The delivered water temperature (T ) at the appliance outlet shall be as follows (see Figures A.1 and A.2):
d
a) Appliances with an adjustable temperature: the tests shall be carried out at a temperature not greater
than 65 °C, with a minimum temperature increase equal to or greater than 45 K above water inlet
temperature;
b) Appliances with a fixed temperature: the tests shall be carried out at the temperature specified in the
appliance documentation, with a minimum temperature increase equal to or greater than 45 K.
The same conditions of initial adjustment stated in the appliance documentation shall be used for all the tests.
These conditions shall be included in the test report.
4.4.6 Electrical supply
The appliance shall be supplied with the nominal voltage or a voltage included within the range of nominal
voltages stated in the installation instructions.
5 Determination of the energy consumption of the appliance
5.1 General
This clause defines the test methods to be employed in determining the energy consumption of appliances.
5.2 Tapping cycles
All patterns define a 24 h measurement cycle and within that cycle the starting times and the total energy
content (in kWh equivalent of hot water tapped) of each draw-off are defined.
Furthermore, the draw-off can be characterized in two ways, either “basin” type draw-off versus “continuous
flow” draw-off.
The aim of the “basin” type is to arrive at an average temperature of the tub, so all supplied energy can be
considered useful from the very beginning of the draw-off (minimum useful temperature increase is 0 K). The
average temperature rising (ΔT desired) to be achieved during tapping, shall be for floor cleaning and bath
30 K and for the dish washes 45 K.

prEN 13203-6:2015 (E)
The aim of the “continuous flow” type is to use only the water with a minimum temperature. For the shower,
household cleaning and large draw-offs a temperature rise of 30 K shall be reached before counting the useful
energy. For the small draw-offs a temperature rise of 15 K shall be reached.
NOTE 1 The temperature rises (in K) stated above are equivalent to the temperatures (in °C) given by the load profiles
tables in Regulations n° 811/2013, n° 812/2013, n° 813/2013 and n° 814/2013 based on 10 °C inlet water temperature.
The tapping flow rates used to perform the different types of tapping of each of the seven tapping cycles defined by
Table 2 to Table 8.
When the tapping rates result in a tapping period of less than 15 s the flow rate should be decreased such that
the tapping period is (16 ± 1) s.
In the tapping cycles, the requirements for flow and temperatures are based on the delivery on the taps in a
mix of hot and cold water. Under the conditions of the initial adjustment, the appliance itself produces hot
water with a minimum temperature rise of 45 K.
To fulfil the requirements stated in Table 2 to Table 8 mixing hot water from the appliance with cold water of
10 °C at the tap is allowed either by using a mixing device (see Figure B.5) or by recalculating the minimum
appliance flow rate (see 3.19) according to the following formula:
DT
useful
D = D ⋅
(1)
min useful(ΔT )
DT
d
where
D is the minimum test rig setting for the appliance flow rate of each individual tapping at
min
temperature rise corresponding to ΔT , in l/min;
d
D is the useful water flow rate according to Tables 2 to 8, in l/min;
useful (ΔT)
ΔT is the delivered water temperature rise with a minimum of 45 K, in K;
d
ΔT is the higher value between the temperature rise to be achieved and the minimum
useful
temperature rise for counting the useful energy according to Table 2 to Table 8, in K.
The tests shall be performed by using the useful flow rates defined by Table 2 to Table 8. If the appliance
cannot deliver these flow rates, for instance due to the flow restrictor, it shall be checked that the requirements
are fulfilled by checking that D is delivered.
min
If by design the appliance is fitted with a flow restrictor, the tests shall be carried out with this flow restrictor.
