PREN 13203-4-2018 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 document 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 400 kW@ ?? an electrical output not exceeding 50 kW@ and ?? a hot water storage capacity (if any) not exceeding 2 000 l. EN 13203-1:2015 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. FprEN 13203-2:2018 is used for performance assessment of these generators.
