This document is applicable to gas-fired appliances producing domestic hot water. It applies to condensing combination boilers with passive flue heat recovery device (PFHRD) that have: - a heat input not exceeding 400 kW; - a hot water storage tank capacity (if any) not exceeding 2 000 l; - a declared load profile between M to 4XL. In the case of combination boilers, with or without storage tank, domestic hot water production is integrated or coupled, the whole being marketed as a single unit. For this document, some tests and calculation results of EN 13203-2:2022 are used to calculate the energy consumptions
