Gas-fired domestic appliances producing hot water - Part 4: Assessment of energy consumption of gas combined heat and power appliances (mCHP) producing hot water and electricity
This European Standard is applicable to gas-fired mCHP 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 mCHP appliances marketed as single unit or as a package fully specified by a manufacturer that have:
- a gas heat input not exceeding 70 kW;
- an electrical output not exceeding 50 kW and
- a hot water storage capacity not exceeding 500 l.
EN 13203 1 sets out in qualitative and quantitative terms the performance in delivery of domestic hot water for a 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 gas fired mCHP 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.
When the mCHP generator does not supply domestic hot water in the summer period, the present standard is not applicable. EN 13203 2 will be used for performance assessment of these generators.
Gasbeheizte Geräte für die sanitäre Warmwasserbereitung für den Hausgebrauch - Teil 4: Bewertung des Energieverbrauchs von Gasgeräten mit Kraft-Wärme-Kopplung (Mikro-KWK) zur Warmwasserbereitung und Stromerzeugung
Diese Europäische Norm ist anwendbar auf gasbefeuerte Geräte mit Mikro-Kraft-Wärme-Kopplung (µKWK-Geräte), die häusliches sanitäres Warmwasser und elektrische Energie bereitstellen. Die elektrische Energie wird in einem Prozess erzeugt, der mit der Bereitstellung von Nutzwärme verbunden ist.
Sie ist anzuwenden auf µKWK-Geräte, die als Einheit vermarktet werden oder für Systeme, die von einem Hersteller umfassend beschrieben sind und:
- eine Gaswärmebelastung von 70 kW nicht überschreiten,
- eine elektrische Leistung von 50 kW nicht überschreiten und
- ein Warmwasserspeichervolumen von 500 l nicht überschreiten.
EN 13203 1 legt mehrere qualitative und quantitative Leistungsstufen für die sanitäre Warmwasserbereitung für eine Auswahl von Benutzungsarten fest. Sie enthält ebenfalls ein System zur Bereitstellung von Angaben für den Betreiber.
Das vorliegende Dokument legt ein Verfahren zur Bewertung des Energieverhaltens der gasbefeuerten µKWK-Geräte fest. Es definiert eine Anzahl täglicher Zapfprogramme für die häusliche Warmwasser¬verwendung in der Küche, zum Duschen und Baden und für Kombinationen dieser Verwendungsarten und legt die entsprechenden Prüfverfahren fest, die den Vergleich des Energieverhaltens unterschiedlicher gasbe¬feuerter Geräte ermöglichen und auf die Bedürfnisse des Benutzers ausgerichtet sind.
Wenn der µKWK-Generator im Sommer kein sanitäres Warmwasser liefert, ist die vorliegende Norm nicht anwendbar. Zur Bewertung der Leistung dieser Generatoren wird die EN 13203-2 angewendet.

Plinske gospodinjske naprave za pripravo tople sanitarne vode - 4. del: Ocenjevanje rabe energije plinskih naprav za soproizvodnjo tople vode in elektrike (mCHP)
Ta evropski standard se uporablja za plinske naprave za soproizvodnjo tople vode in elektrike (mCHP). Električna energija se proizvaja v procesu, povezanim s proizvodnjo uporabne toplote.
Uporablja se za vse naprave mCHP, ki so na trgu na voljo kot ena enota ali kot paket in pri katerih po navedbah proizvajalca:
– toplotna moč plina ne presega 70 kW;
– električna moč ne presega 50 kW in
– prostornina za vročo vodo ne presega 500 l.
Standard EN 13203 1 v kakovostnem in količinskem smislu določa zmogljivost za pripravo tople sanitarne vode za različne namene. Zajema tudi sistem za predstavitev informacij uporabniku.
Ta dokument določa metodo za ocenjevanje energetske učinkovitosti plinskih naprav mCHP. 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.
Ko generator mCHP ne dobavlja tople sanitarne vode v poletnem obdobju, se trenutni standard ne uporablja. Za oceno zmogljivosti takšnih generatorjev se bo uporabljal standard EN 13203 2.
