Residential solid fuel burning appliances - Part 2-7: Combination appliances fired by wood logs and pellets
This document is applicable to space heaters, inset appliances and cookers intended for mechanical fuelling with wood pellets and for manual fuelling with wood logs. They can be freestanding or inset appliances.
The intended use of the appliances is space heating in residential buildings and can be cooking. They can be fitted with a boiler (integral part of the appliance containing water to be heated up) for the supply of hot water for central heating systems.
These appliances typically use auxiliary energy which is measured in this standard as well. They are operated with natural draught and can be fan-assisted.
NOTE 1 A fan-assisted appliance does still operate under negative pressure in the flue gas system.
For inset appliances and especially their testing additional information can be necessary from EN 16510-2-2:2022.
These appliances burn wood pellets and wood logs only, in accordance with the appliance instructions. They only operate with the firedoors closed.
NOTE 2 These appliances can have an integral fuel hopper or be combined with an external fuel hopper.
These appliances can be fitted with a single or double combustion chamber having a single flue gas outlet.
This document specifies procedures for assessment and verification of constancy of performance (AVCP) of characteristics of combination appliances fired by wood logs and pellets.
This document is not applicable to appliances:
- with boiler intended for water systems having water temperatures above 110°C and 3 bar and for 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,
- with simultaneous wood and pellet operation with a single flue gas outlet,
- with non-automatic pellet loading,
- with single combustion chamber and double flue gas outlet,
- continuous burning appliances.
For clarity, all test methods are addressed in Annex A.

Grelne naprave na trdna goriva za stanovanjske stavbe - 2-7. del: Kombinirane naprave na lesna polena in pelete
Ta dokument se uporablja za grelnike prostorov, vgradne naprave in štedilnike, namenjene za mehansko kurjenje z lesnimi peleti in ročno kurjenje z lesnimi poleni. Takšne naprave so lahko prosto stoječe ali vgradne. Naprave so namenjene ogrevanju prostorov v stanovanjskih stavbah in tudi kuhanju. Opremljene so lahko s kotlom (sestavni del naprave, ki vsebuje vodo, ki jo je treba segreti) za oskrbo sistemov centralnega ogrevanja s toplo vodo. Te naprave običajno uporabljajo pomožno energijo, ki se tudi meri v tem standardu. Delujejo lahko z naravnim vlekom in s pomočjo ventilatorja. OPOMBA 1: Naprava z ventilatorjem še vedno deluje s podtlakom v izpušnem sistemu. Za vgradne naprave in zlasti njihovo preskušanje so lahko potrebne dodatne informacije iz standarda EN 16510-2-2:2022. V skladu z navodili za uporabo je v teh napravah mogoče kuriti samo lesne pelete in lesna polena. Delujejo le, ko so protipožarna vrata zaprta. OPOMBA 2: Te naprave imajo lahko vgrajen rezervoar za gorivo ali pa so kombinirane z zunanjim rezervoarjem za gorivo. Opremljene so lahko z enojno ali dvojno zgorevalno komoro z enojnim odvodom dimnih plinov. Ta dokument določa postopke za ocenjevanje in preverjanje nespremenljivosti lastnosti (AVCP) kombiniranih naprav na lesna polena in pelete. Ta dokument se ne uporablja za naprave: – s kotlom, namenjenim za vodne sisteme s temperaturo vode nad 110 °C in 3 bari ter za sanitarno toplo vodo; – namenjene za uporabo samo z vodoravnim izpuhom (skozi steno stavbe); – s kondenzacijo dimnih plinov v napravi; – z vklopom/izklopom pri delni obremenitvi; – s sočasnim delovanjem na drva in pelete z enojnim odvodom dimnih plinov; – z neavtomatskim nalaganjem peletov; – z enojno zgorevalno komoro in dvojnim odvodom dimnih plinov; – z neprekinjenim gorenjem. Zaradi jasnosti so vse preskusne metode obravnavane v dodatku A.
