European foreword
This document (EN 16510-2-5:2025) has been prepared by Technical Committee CEN/TC 295
“Residential solid fuel burning appliances”, the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by October 2025, and conflicting national standards shall
be withdrawn at the latest by October 2025.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 15250:2007.
EN 16510-2-5 includes the following significant technical changes with respect to EN 15250:2007:
— the scope is updated with space heating appliances in residential buildings that can be fitted with a
boiler or heat exchanger (integral part of the appliance containing water to be heated up) for the
supply of hot water for central heating systems integral boiler or heat exchanger water heat output
— Measurement methods for NO , hydrocarbon and particulate matter emissions for solid fuel burning
x
appliances;
— specifications for classification of solid fuel burning appliances and system boundaries for room
sealed appliances;
— requirements for the safety of solid fuel burning appliances with water-bearing components added;
— Annex ZA updated according to requirements of M/577;
— Assessment and verification of constancy of performance – AVCP 3+ added;
— energy efficiency and energy class labelling and seasonal space heating efficiency added;
— requirements for environmental sustainability added.
This document has been prepared under a standardization request given to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
For relationship with (EU) Regulation 305/2011, see informative Annex ZA, which is an integral part of
this document.
The structure of EN 16510, Residential solid fuel burning appliances, is as follows:
— Part 1: General requirements and test methods;
— Part 2-1: Roomheaters;
— Part 2-2: Inset appliances including open fires;
— Part 2-3: Cookers;
— Part 2-4: Independent boilers – Nominal heat output up to 50 kW;
— Part 2-5: Slow heat release appliances;
— Part 2-6: Mechanically by wood pellets fed roomheaters, inset appliances and cookers.
Other sections of Part 2 will be added to cover residential solid fuel burning appliances not included in
parts 2-1 to 2-6.
Subclauses and Figures which are additional to those in EN 16510-1:2022 are numbered starting with

Introduction
The energy efficiency classification is aligned with Commission Regulation (EU) 2015/1186, Annex II.
Upon the revision of Regulation (EU) 2015/1186, the standard should be updated to reflect the new
classification.
The threshold levels for OGC, CO, NOx and PM emissions and the threshold levels for the seasonal space
heating energy efficiency are aligned with Commission Regulation (EU) 2015/1185, Annex II. Upon the
revision of Regulation 2015/1185, the standard should be updated to reflect the new classification.
1 Scope
This document is applicable to slow heat release appliances for solid fuel (freestanding manually fuelled
intermittent burning slow heat release appliances (SHRA) having heat storage capacity such that they
can provide heat and release it for an extended period after the fire has gone out).
The intended use of the appliances is space heating in residential buildings. They can be fitted with a
boiler or heat exchanger (integral part of the appliance containing water to be heated up) for the supply
of hot water for central heating systems.
These slow heat release appliances may be supplied either as an assembled appliance or as a pre-
designed unit consisting of prefabricated components designed to be built on site in accordance with the-
specified assembly instructions.
These appliances can burn one or more types of the following solid fuels as specified:
— wood logs;
— compresse
