M/577 - Space heating appliances REV

This document is applicable to freestanding or inset roomheaters fired by solid fuel, without functional modification that operate with fire doors either as closed only or as closed or open.
The appliances covered by this document provide heat into the space where they are installed. Additionally, where fitted with a boiler, they also provide domestic hot water and/or central heating.
These appliances can burn one or more types of the following solid fuels in accordance with the appliance manufacturer’s instructions:
-   wood logs;
-   compressed untreated wood;
-   wood pellets;
-   lignite briquettes;
-   solid mineral fuels;
-   peat briquettes.
This document is not applicable to appliances with fan assisted combustion air or appliances that are mechanically fed.
This document is used in conjunction with EN 16510 1 of which it is an integral part.

This document is applicable to hand fed solid fuel fired inset appliances, with or without functional modification, that operate without firedoors or operate with fire doors either as closed only or as closed or open, and also includes open fires fired by solid fuel. The surround of these appliances are integrated with the building with the exception of free-standing appliances and those inset appliances which are installed into a fireplace recess or enclosure. These appliances provide heat into the space where they are installed. Additionally, where fitted with a boiler, they also provide domestic hot water and/or central heating.
These appliances can burn one or more types of the following solid fuels in accordance with the appliance manufacturer’s instructions:
-   wood logs;
-   compressed untreated wood;
-   wood pellets;
-   lignite briquettes;
-   solid mineral fuels;
-   peat briquettes.
This document also covers ‘Kachelofen’ and ‘Putzofen’ inset appliances, having nominal heat outputs up to 15 kW.
This document is not applicable to appliances with fan assisted combustion air or appliances that are mechanically fed.
Open fireplace components such as a bottomgrate with associated firefront which the manufacturer supplies for installation into an existing heat resistant, insulated firebox are not covered by this document.
This document is used in conjunction with prEN 16510 1:2021 of which it is an integral part.

This document is applicable to hand fired residential cookers whose primary function is to cook and whose secondary function is to provide heat into the space in which they are installed. Additionally, where fitted with a boiler, they also provide domestic hot water and/or central heating.
These appliances can burn one or more types of the following solid fuels in accordance with the appliance manufacturer’s instructions:
-   wood logs;
-   compressed untreated wood;
-   wood pellets;
-   lignite briquettes;
-   solid mineral fuels;
-   peat briquettes.
This document is not applicable to appliances with fan assisted combustion air or appliances that are mechanically fed.
This document is used in conjunction with prEN 16510 1 of which it is an integral part.

This document is applicable to hand and automatically fired residential independent boilers (hereafter called appliances) having a nominal heat outputs up to 50 kW.
The primary function of the appliance is to provide hot water for central heating and/or domestic use. In addition to their primary function of providing hot water these appliances also provide space heating to the place of installation. They are designed for use only with open vented systems at a working pressure not exceeding 2 bar.
The appliances can burn one or more types of the following solid fuels in accordance with the appliance manufacturer’s instructions:
-   wood logs;
-   compressed untreated wood;
-   wood pellets;
-   lignite briquettes;
-   solid mineral fuels;
-   peat briquettes.
The appliances are operated closed and / or open.
The appliances are typed according to their tightness depending on their designation in accordance with a possible operation together with a room ventilation system.
This document is not applicable to appliances for hot water only production and having heat outputs of less than 5 kW.
This document is also not applicable for automatic stoking devices.
This document is used in conjunction with EN 16510 1 of which it is an integral part.

This document is applicable to space heaters, inset appliances and cookers fired by wood pellets, mechanically fed up to 50 kW nominal heat output. These appliances typically use auxiliary energy which is measured in this document as well.
For inset pellet appliances and especially their testing, additional information from prEN 16510 2 2:2021 is relevant.
For pellet cookers and especially their testing, additional information from prEN 16510 2 3:2021 is relevant.
Non-mechanically fed appliances burning solid mineral fuels, peat briquettes and natural or manufactured wood logs are not included in this document, but are covered by prEN 16510 2 1:2021 to prEN 16510 2 5:2021.
NOTE 1   These appliances could have an integral fuel hopper or be combined with an external fuel hopper.
This document is used in conjunction with prEN 16510 1:2021.
The appliances covered by this document provide heat into the space where they are installed. They can be operated with either natural draught or fan-assisted combustion air. Where fitted with a boiler, they can also provide domestic hot water and/or central heating. These appliances burn wood pellets only, in accordance with the appliance manufacturer's instructions. They only operate with the firedoors closed.
NOTE 2   A fan-assisted appliance does still operate under negative pressure in the flue gas system.
This document specifies requirements relating to the design, manufacture, construction, safety and performance (efficiency and emissions), instructions and marking together with associated test methods and test fuels.
This document is not applicable to appliances:
-   with boiler intended for water systems having water temperatures above 110°C and 3 bar;
-   with boiler intended for water systems having direct contact with sanitary hot water;
-   intended to be used with a pure horizontal exhaust (through the building wall);
-   with flue gas condensation in the appliance;
-   switching on / off for part load operation.
