9 Introduction The safety operation of the boiler or water heater is not covered by this standard. Safety should be proved by means of the essential safety requirements of the Gas Appliances Directive 2009/142/EC. This may be achieved by compliance with the appropriate existing harmonized standards. NOTE 1 Useful standards are EN 26, EN 89 and series EN NOTE 2 The Gas Appliances Directive 2009/142/EC has been replaced by the Gas Appliances Regulation 426/2016/EU. 5

10 1 Scope This European Standard is applicable to gas-fired appliances producing domestic hot water. It applies to both instantaneous and storage gas-fired combined with electrical heat pump. It applies to a package marketed as single unit or fully specified by the manufacturer that have: a heat input not exceeding 400 kw; and a hot water storage tank capacity (if any) not exceeding 2000 l. EN 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 gas fired appliances combined with heat pump with electrically driven compressor according to EN It defines a number of daily load profiles 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 apply. The present document does not apply for gas boilers with recovery systems using combustion products as heat source for the electrical heat pump. When the electrical heat pump does not work for domestic hot water production in the summer period, the present standard is not applicable for energy performances assessing, EN should be used. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
