Abstract
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 package marketed as single unit or a package fully specified by a manufacturer that have:- a gas heat input not exceeding 70 kW; - an electrical output not exceeding 50 kWe; - 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. EN 13203-3 deals with the assessment of energy consumption of solar supported gas-fired domestic appliances producing hot water. This part 4 sets out a method for assessing the energy performance of gas fired micro CHP appliances.
