Gas fired domestic appliances producing hot water - Part 4: assessment of energy consumption of gas fired appliances combined heat and power (micro CHP) producing hot water and electricity not exceeding 70 kW heat input, not exceeding 50 kWe electrical output and 500 l water storage capacity

This European Standard is applicable to gas-fired micro CHP appliances producing domestic hot water and electricity. The electricity is generated in a process linked to the production of useful heat.
It applies to a system marketed as single unit or a system fully specified by a manufacturer that have:
- a gas heat input not exceeding 70 kW;
- an electrical output not exceeding 50 kWe; and
- a hot water storage capacity not exceeding  500 litres.
This European Standard EN 13203 is formed in four parts which cover aspects of domestic hot water production.
Standard 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. This first part complements EN 26, EN 89 and EN 625.
Standard EN 13203-2 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.
Standard EN 13203-3 deals with solar systems.
Note : a draft standard prEN 13203-5 for "Gas-fired domestic appliance producing hot water - Part 5 : Assessment of energy consumption of gas fired appliances combined with electrical heat pump not exceeding 70 kW heat input and 300 l water storage capacity" is also under preparation by CEN/TC109/WG4.
All standards and drafts series EN 13203 are worked out under Mandate M324 against Energy Labelling Directive 92/75/EC under revision.

4 General test conditions
4.1 Reference conditions
Unless otherwise stated, the general test conditions are as follows :
 cold water temperature: (10 ± 2) °C;
 cold water pressure: (2 ± 0,1) bar;
 ambient air temperature: (20 ± 3) °C;
 electrical supply voltage:
 (230 ± 2) V single phase;
 (400 ± 4) V three phase.
 electrical output voltage :
 (230 ± 2) V single phase;
 (400 ± 4) V three 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.
These uncertainties correspond to two standard deviations.
The laboratory evaluates these standard deviations 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 :

---------------------- Page: 7 ----------------------
oSIST prEN 13203-4:2011
prEN 13203-4:2010 (E)
 ambient: ± 1 °C;
 water: ± 0,5 °C;
 gas: ± 0,5 °C;
 mass: ± 0, 5 %;
 gas pressure: ± 2 %;
 gas calorific value: ± 1 %;
 gas density: ± 0,5 %;
 electrical auxiliary energy: ± 2 %.
 electrical generated 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 %.
4.3 Test conditions
4.3.1 General
The tests are carried out in the summer mode when the appliance is producing domestic hot water only. .
4.3.2 Test room
The appliance is installed in a well-ventilated, draught-free room (air speed less than 0,5 m/s).
The appliance is protected from direct solar radiation.
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 are 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 are 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 by the manufacturer.
The hot water temperature is 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 are regarded as established when the rate of change of the domestic hot water
temperature at the appliance outlet has become less than the temperature fluctuation at constant water rate (∆T

2
).
according to 3.8 of EN 13203-1
4.3.5 Initial adjustment of the appliance
The appliance is installed in accordance with the manufacturer's instructions.
The heat input shall be adjusted to within ± 2 % of the nominal domestic hot water heat input under the conditions
prevailing at the time of the test.
The delivered water temperature at the appliance outlet is defined as follows :
a) appliances with an adjustable temperature : the tests are carried out at a temperature not greater than 65 °C,
with a minimum temperature increase equal to or greater than 45 K above cold water inlet temperature.
b) appliances with a fixed temperature : the tests are carried out at the temperature specified by the
manufacturer, with a minimum temperature increase equal to or greater than 45 K above cold water inlet
temperature.
The same conditions of initial adjustment stated by the manufacturer and used for all the tests specified in EN
13203-1 are also used for the tests of this standard. These conditions are included in the test report.
4.3.6 Electrical supply
The appliance is supplied with the nominal voltage or a voltage included within the range of nominal voltages.
4.3.7 Electrical energy output
Arrangement shall be made to enable electrical energy output to be measured.
NOTE The electrical output to be measured may be dissipated by a resistor or injected in the grid.
5 Determination of the energy consumption and electrical energy generation of
appliances
5.1 General
This clause defines the test methods to be employed in determining the energy consumption and electrical energy
generation of appliances.
5.2 Tapping cycles
5.2.1 General
All patterns define a 24h 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 characterised in two ways, either :
a) “Basin” type draw-off (bath, dishwash) versus “continuous flow” draw-offs (shower, etc).
The aim of the former 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 latter start to be useful only from a certain temperature (minimum useful temperature increase is 15 K
lower than the desired temperature), or
b) “Dish washing” type draw-off which are carried out with a water temperature of 45 K rather than the 30 K
in a).
The tapping flow rates used to perform the different types of tapping of each of the five tapping cycles defined by
Tables 2 to 6 should be taken as given by Table 1.
When these tapping rates result in a tapping period of less than 15 seconds the flow rate should be decreased
such that the tapp
