This European Standard is applicable to gas-fired appliances producing domestic hot water. It applies to
sorption heat pumps connected to or including a domestic hot water storage tank. It applies to a package
marketed as single unit or fully specified that have:
- a single gas burner for the heat pump and/or an additional gas burner for a peak load appliance;
- a gas heat input not exceeding 70 kW;
- a hot water storage tank capacity not exceeding 500 litres.
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.
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.
When the sorption heat pump cycle does not operate for domestic hot water production in the summer mode,
the present standard is not applicable for energy performance assessment, EN 13203-2 must be used
instead.
