Gas-fired domestic appliances producing hot water - Appliances not exceding 70 kW heat input and 300 l water storage capacity - Part 1: Assessment of performance of hot water deliveries

This document is applicable to gas-fired appliances producing domestic hot water. It applies to both instantaneous and storage appliances; water-heaters and combination boilers that have:
- heat input not exceeding 70 kW; and
- hot water storage capacity (if any) not exceeding 300 l.
In the case of combination boilers, with or without storage, domestic hot water production is integrated or coupled, the whole being marketed as a single unit.
This document is formed in two parts, which cover two aspects of domestic hot water production.
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.
EN 13203-2 sets out a method for assessing the energy performance of the appliances. It defines a number of daily delivery programmes 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.

Gasbeheizte Geräte für die sanitäre Warmwasserbereitung für den Hausgebrauch - Geräte, die eine Nennwärmebelastung von 70 kW und eine Speicherkapazität von 300 Liter Wasser nicht überschreiten - Teil 1: Bewertung der Leistung der Warmwasserbereitung

Diese Europäische Norm gilt für gasbeheizte Geräte für die häusliche sanitäre Warmwasserbereitung. Sie gilt sowohl für Durchlauf-Wasserheizer als auch für Vorratswasserheizer und Kombi-Kessel mit Speicher, welche
-   eine Wärmebelastung von 70 kW nicht überschreiten und
-   ein Speichervolumen von 300 l nicht überschreiten.
Bei Kombi-Kesseln mit oder ohne Vorratsbehälter ist die häusliche Warmwasserbereitung im Kessel eingebaut oder am Kessel angebaut. Das gesamte Gerät wird als eine Gesamteinheit vertrieben.
Diese Europäische Norm besteht aus zwei Teilen, die zwei Arten der häuslichen Warmwasserbereitung behandeln:
Der erste Teil EN 13203-1 legt mehrere quantitative und qualitative Niveaus für den Komfort von sanitärem Warmwasser für eine Auswahl von Benutzungsarten fest. Er enthält ebenfalls Hinweise zur entsprechenden Information des Betreibers. Dieser erste Teil vervollständigt EN 26, EN 89 und EN 625.
Der zweite Teil EN 13203-2 legt eine Methode zur Bewertung des Energieverhaltens von Geräten fest. Er definiert eine Anzahl täglicher Zapfprogramme für die häusliche Warmwasserverwendung in der Küche, zum Duschen und Baden und für Kombinationen dieser Verwendungsarten. Weiterhin legt er die entsprechenden Prüfverfahren fest, mit denen das Energieverhalten unterschiedlicher Geräte verglichen und auf die Bedürfnisse des Betreibers ausgerichtet werden kann.

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 :  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 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 %.



EN 13203-1:2006 (E) 8 4.3 Test conditions 4.3.1 General Except where otherwise stated, the appliance is tested under the following conditions. 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:  domestic water pressure is the static inlet pressure under dynamic conditions measured as close as possible to the appliance;  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.
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 (∆T2). 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 determined according to the relevant clause of EN 625 under the conditions prevailing at the time of the test.
The delivered water temperature at the appliance outlet is defined as follows (see Figures A.1.1 and A.1.2): 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 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. The same conditions of initial adjustment stated by the manufacturer are used for all the tests. These conditions are included in the test report.
4.3.6 Initial state conditions All the tests of this standard are conducted as follows (see Figures A.2.1 and A.2.2):



EN 13203-1:2006 (E) 9  when there is no control cycle to consider: at least one hour after the previous delivery;  when there is a control cycle to consider : after a time corresponding to 20 % (but not exceeding 1 h) of the "OFF" time of the burner. The time is taken from the time the burner turns off. The same initial state conditions are used for all the tests. These conditions are included in the test report. For appliances with a central heating function, tests are conducted in summer mode. 4.3.7 Electrical supply The appliance is supplied with the nominal voltage or a voltage included within the range of nominal voltages. 5 Characterisation of the domestic hot water function of appliances 5.1 General The domestic hot water function of domestic hot water appliances is characterised in two different ways:  firstly, according to the domestic hot water specific rates, the tapping capability and the corresponding uses (see 5.2);  secondly, according to the quality of the domestic hot water produced (see 5.3); obtaining a number of stars corresponding to a determined level of performance. 5.2 Characterisation according to the domestic hot water rates 5.2.1 Specific rate 5.2.1.1 Requirement The measured value of the specific rate shall be not lower than 95 % of that stated by the manufacturer. 5.2.1.2 Test The appliance is adjusted to deliver hot water at the rate stipulated by the manufacturer for this test. The pressure loss across the appliance shall not exceed 2 bar. During the measurement of the specific rate, the minimum temperature increase shall be equal to or greater than 30 K. Before the test, the appliance is adjusted in accordance with 4.3.4. A first delivery is carried out over a period of 10 min, followed by 20 min with no delivery and then by a second delivery over a period of 10 min (see Figures A.3.1 and A.3.2). The test follows the sequence:  water delivery of 10 min duration;  20 min period of no water delivery;  further water delivery of 10 min duration. Measurements of temperature and flow rate are made and recorded, at intervals not exceeding 2 s. A plot of temperature against time is made, to obtain the mean water temperature rise during each delivery.
