EN 16510 Residential Solid Fuel Heating Appliances

The European standard “EN 16510 Residential solid fuel heating appliances” consists of the following sub-sections published under the same title:

• The standard “EN 16510-1 Part 1: General requirements and test methods” applies to residential solid fuel heating appliances where the nominal area heat output exceeds 6% of the nominal area heat output and nominal water heat output (total heat output).

This standard describes the requirements and provides instructions for the design, manufacture, construction, safety, and performance (efficiency and emissions) of solid fuel-fired appliances. It also includes provisions for assessing the conformity of these appliances, namely initial type testing and factory production control and marking.

This standard specifies emission test methods for carbon monoxide, nitrogen oxides, organic gaseous carbon, and particulate matter. This standard also applies to appliances intended to carry flue gas loads.

Appliances that draw combustion air from the outside of the building through a non-airtight duct system are not considered to have achieved room airtightness.

This standard does not apply to appliances with boiler parts that come into contact with fire or flue gases, unless the boiler parts are made of steel or cast iron. It also does not apply to appliances with boilers designed for water systems with the following characteristics:

• Water temperature above 110 degrees or working pressure above 300 kPa (3 bar)
• Directly in contact with hot water.

This standard does not apply to devices that are intended to operate with ventilation systems where the device is intended to operate at a pressure below -15 Pa relative to the outside atmosphere in the installation room.

• The standard “EN 16510-2-1 Part 2-1: Room heaters” applies to residential solid fuel room heaters, which are freestanding or built-in appliances designed specifically for local area heating in residential buildings. These typically operate with closed fire doors and burn solid fuels such as logs, briquettes, or other approved solid biofuels.

It is part of the modular EN 16510 series of standards, which replaces many older standards, particularly the EN 13240 standard for room heaters, with the aim of harmonizing safety, performance, emission and efficiency requirements for solid fuel appliances across the EU.

This standard does not cover open fires without doors, stoves, boilers, pellet-fired appliances (which fall under other sections such as EN 16510-2-6), or appliances with significant functional modifications.

The intended use is space heating in residential buildings. Some models may include an integrated boiler for hot water.

This standard works in conjunction with EN 16510-1, which provides common test procedures for emissions, efficiency, and safety. Part 2-1 contains specific requirements and verification procedures for room heaters.

• The standard “EN 16510-2-2 Part 2-2: Built-in appliances including open fireplaces” applies to built-in appliances powered by solid fuel (including hand-fed, functionally modified or unmodified, solid fuel built-in appliances operating without a fire door or with only a closed or both closed and open operation, as well as solid fuel open fireplaces).

The intended use of these devices is for space heating in residential buildings. For central heating systems, they may be equipped with a boiler (an integral part of the device containing the water to be heated) for hot water supply. The surroundings of these devices are integrated with the building, with the exception of freestanding devices and built-in devices mounted in fireplace recesses or housings.

These devices can burn one or more of the following solid fuel types:

• Logs
• Compressed raw wood
• Wood pellets
• Lignite briquettes
• Solid mineral fuels
• Peat briquettes

This standard also applies to built-in appliances with a nominal heat output of up to 15 kW.

This standard does not apply to appliances with fan-assisted combustion air or mechanically fed appliances. Furthermore, open fireplace components such as bottom grates and associated fireboxes intended to be mounted in an existing heat-resistant, insulated firebox are not covered by this document.

This standard specifies procedures for evaluating and verifying the performance continuity of solid fuel built-in appliances, including open fireplaces.

• The standard “EN 16510-2-3 Part 2-3: Cooking appliances” applies to solid fuel cooktops (manually lit residential cooktops). These appliances are intended for cooking and space heating in residential settings. They may be equipped with a boiler (an integral part of the appliance containing the water to be heated) for the purpose of supplying hot water to central heating systems.
