1 Scope
This document is applicable to gas-fired appliances producing domestic hot water.
It applies to both instantaneous and storage gas-fired combined with electric heat
pump.
It applies to a package marketed as single unit or fully specified by the manufacturer
that have:
-
— a heat input not exceeding 400 kW;
-
— a hot water storage tank 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 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 gas fired appliances combined with heat pump with electrically
driven compressor according to EN 16147. 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 boiler or a water heater to produce domestic hot water, specific parts of
EN 13203 apply.
The present document does not apply for gas boilers with recovery systems using combustion
products as heat source for the electrical heat pump.
When the electrical heat pump does not work for domestic hot water production in the
summer period, the present standard is not applicable for energy performances assessing,
instead EN 13203‑2:2022 is applicable.
