1 Scope
This document is applicable to gas-fired appliances producing domestic hot water.
It applies to sorption heat pumps connected to or including a domestic hot water storage tank. It applies to a package
marketed as single unit or fully specified that have:
-
— a heat input not exceeding 400 kW;
-
— a hot water storage tank capacity (if any) not exceeding 2 000 l.
In the case of gas-fired sorption heat pumps, with or without storage tank, domestic hot water production is integrated or coupled,
the whole being marketed as a single unit.
EN 13203‑1:2015
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. The present document sets out a method for assessing the
energy performance of the appliances. It specifies a number of daily load profiles
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. Where other
technologies are combined with a gas-fired sorption heat pump to produce domestic hot water, specific parts of EN 13203 apply.
Horizontal ground heat sources are not covered by the scope of the present document.
