Gas-fired domestic appliances producing hot water - Part 7: Assessment of energy consumption of combination boilers equipped with a passive flue heat recovery device
|Publication Date:||1 February 2021|
|ICS Code (Water heating equipment):||91.140.65|
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 2000 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 13203-2:2020 are used to calculate the energy consumptions.
