This European Standard is applicable to gas-fired micro CHP 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 system marketed as single unit or a system fully specified by a manufacturer that have:
- a gas heat input not exceeding 70 kW;
- an electrical output not exceeding 50 kWe; and
- a hot water storage capacity not exceeding 500 litres.
This European Standard EN 13203 is formed in four parts which cover aspects of domestic hot water production.
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. This first part complements EN 26, EN 89 and EN 625.
Standard EN 13203-2 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.
Standard EN 13203-3 deals with solar systems.
Note : a draft standard prEN 13203-5 for "Gas-fired domestic appliance producing hot water - Part 5 : Assessment of energy consumption of gas fired appliances combined with electrical heat pump not exceeding 70 kW heat input and 300 l water storage capacity" is also under preparation by CEN/TC109/WG4.
All standards and drafts series EN 13203 are worked out under Mandate M324 against Energy Labelling Directive 92/75/EC under revision.
