EN 13203-2:2006

Gas-fired domestic appliances producing hot water - Appliances not exceeding 70 kW heat input and 300 l water storage capacity - Part 2: Assessment of energy consumption

Publication date:   Nov 14, 2006

Scope

This European Standard is applicable to gas-fired appliances producing domestic hot water. It applies to both instantaneous and storage appliances; waters-heaters and combination boilers that have:
¾ heat input not exceeding 70 kW, and
¾ hot water storage capacity (if any) not exceeding 300 l.
In the case of combination boilers, with or without storage, domestic hot water production is integrated or coupled, the whole being marketed as a single unit.
This European Standard EN 13203 is formed in two parts, which cover two aspects of domestic hot water production.
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.
The present European 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.
