Resumen:
This European Standard is applicable to gas-fired mCHP appliances producing domestic hot water andelectricity. 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 thathave:- a gas heat input not exceeding 70 kW;- an electrical output not exceeding 50 kW and- a hot water storage capacity not exceeding 500 litres.Standard EN 13203-1 sets out in qualitative and quantitative terms the performance in delivery of domestichot 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 mCHPappliances. It defines a number of daily tapping cycles for each domestic hot water use, kitchen, shower, bathand a combination of these, together with corresponding test procedures, enabling the energy performancesof 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 isnot applicable. EN 13203-2 must be used for performance assessment of these generators.
