4 General test conditions
4.1 Reference conditions
Unless otherwise stated, the general test conditions shall be as follows:
— cold water temperature: 10 °C;
— maximum average variation over the test period: ± 2 K;
— cold water pressure: (2 ± 0,1) bar;
— ambient air temperature: 20 °C;
— maximum average variation over the test period ± 1 K;
— maximum variation during the tests ± 2 K;
— electrical supply voltage: (230 ± 2) V (single phase).
4.2 Measurement uncertainties
Except where otherwise stated in the clauses describing the tests, the uncertainties of measurements carried
out shall be not greater than the maximum uncertainties indicated below.
The standard deviations shall be evaluated taking account of the various sources of uncertainty: contribution
from the instrument, repeatability, calibration, ambient conditions, etc.
— water rate: ± 1 %;
— gas rate: ± 1 %;
— time: ± 0,2 s;
— temperatures:
— ambient: ± 1 K;
— water: ± 0,5 K;
— gas: ± 0,5 K;
— mass: ± 0,5 %;
— gas pressure: ± 1 %;
— gas calorific value: ± 1 %;
— gas density: ± 0,5 %;
— electrical energy: ± 2 %.
The stated measurement uncertainties relate to individual measurements. For measurements that combine a
number of individual measurements, smaller uncertainties on the individual measurements may be necessary
to ensure a total uncertainty within ± 2 % under the steady state conditions.
These uncertainties correspond to two standard deviations (2σ).

EN 13203-2:2015 (E)
4.3 Test conditions
4.3.1 General
Except where otherwise stated, the appliance is tested under the following conditions.
For combination gas boiler, the tests shall be carried out only in summer mode as defined in 3.3, and the
appliance shall be set in summer mode.
For all tests defined by this standard, the same adjustment of the appliance shall be maintained.
4.3.2 Test room
The appliance shall be installed in a well-ventilated, draught-free room (air speed less than 0,5 m/s).
The appliance shall be protected from direct solar radiation and radiation from heat generators.
4.3.3 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 shall be 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 the 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.
The hot water temperature shall be measured with a rapid response temperature sensor.
"Rapid response temperature sensor" 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.
4.3.4 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.
4.3.5 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 Figure A.1 and Figure
d
A.2):

EN 13203-2:2015 (E)
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.
4.3.6 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) to be achieved during tapping, shall be for floor cleaning and bath 30 K and
for the dish washes 45 K.
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 are defined by
Tables 1 to 7.
When these 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 Tables 1 to 7 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 3.13) according to the following formula:

1 Scope
This European Standard is applicable to gas-fired appliances producing domestic hot water. It applies to both
instantaneous and storage tank appliances; waters-heaters and combination boilers that have:
— a heat input not exceeding 70 kW; and
— a hot water storage tank capacity (if any) not exceeding 500 l.
In the case of combination boilers, with or without storage tank, domestic hot water production is integrated or
coupled, the whole being marketed as a single unit.
EN 13203-1 sets out in qualitative and quantitative terms the performance in delivery of domestic hot water for
a selected variety of uses. It also gives a system for presenting the information to the user. The present
document sets out a method for assessing the energy performance of the appliances. It defines a number of
daily tapping cycles for each domestic hot water use, kitchen, shower, bath and a combination of these,
together with corresponding test procedures, enabling the energy performances of different gas-fired
appliances to be compared and matched to the needs of the user. Where other technologies are combined
with a gas-fired boiler or a water heater to produce domestic hot water, specific parts of EN 13203 apply.

4 General test conditions
4.1 Reference conditions
Unless otherwise stated, the general test conditions shall be as follows:
— cold water temperature: 10 °C;
— maximum average variation over the test period: ± 2 K;
— cold water pressure: (2 ± 0,1) bar;
7

---------------------- Page: 9 ----------------------
kSIST FprEN 13203-2:2014
FprEN 13203-2:2014 (E)
— ambient air temperature: 20 °C;
— maximum average variation over the test period ± 1 K;
— maximum variation during the tests ± 2 K;
— electrical supply voltage: (230 ± 2) V (single phase).
4.2 Measurement uncertainties
Except where otherwise stated in the clauses describing the tests, the uncertainties of measurements carried
out shall be not greater than the maximum uncertainties indicated below.
The standard deviations shall be evaluated taking account of the various sources of uncertainty: contribution
from the instrument, repeatability, calibration, ambient conditions, etc.
— water rate: ± 1 %;
— gas rate: ± 1 %;
— time: ± 0,2 s;
— temperatures :
— ambient: ± 1 K;
— water: ± 0,5 K;
— gas: ± 0,5 K;
— mass: ± 0,5 %;
— gas pressure: ± 1 %;
— gas calorific value: ± 1 %;
— gas density: ± 0,5 %;
— electrical energy: ± 2 %.
The stated measurement uncertainties relate to individual measurements. For measurements that combine a
number of individual measurements, smaller uncertainties on the individual measurements may be necessary
to ensure a total uncertainty within ± 2 % under the steady state conditions.
These uncertainties correspond to two standard deviations (2σ).
4.3 Test conditions
4.3.1 General
Except where otherwise stated, the appliance is tested under the following conditions.
For combination gas boiler, the tests shall be carried out only in summer mode as defined in 3.3, and the
appliance shall be set in summer mode.
For all tests defined by this standard, the same adjustment of the appliance shall be maintained.

4.3.2 Test room
The appliance shall be installed in a well-ventilated, draught-free room (air speed less than 0,5 m/s).
The appliance shall be protected from direct solar radiation and radiation from heat generators.
4.3.3 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 shall be 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 the 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.
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.
4.3.4 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.
4.3.5 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 Figure A.1 and Figure
d
A.2):
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.

4.3.6 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) to be achieved during tapping, shall be for floor cleaning and bath 30 K and
for the dish washes 45 K.
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 are defined by
Tables 1 to 7.
When these 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 Tables 1 to 7 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 3.13) according to the following formula:
∆T
