| Title | Gas appliances - Combined heat and power appliance of nominal heat input inferior or equal to 70 kW |
| Project Number | 21817 |
| Abstract/Scope | This European Standard specifies the requirements and test methods for the construction, safety, fitness for purpose, rational use of energy and the marking of a micro combined heat and power appliance; (hereafter referred to as “mCHP appliance”). This European Standard applies to mCHP appliances of types B22, B23, B32, B33, B52, B53, C1, C3, C4, C5, C6, and C8 as classified in CEN/TR 1749 – that use one or more combustible gases of the three gas families at the pressures stated in EN 437, – where the temperature of the heat transfer fluid does not exceed 105 ºC during normal operation, – where the maximum operating pressure in the – heating water circuit does not exceed 6 bar, – domestic hot water circuit (if installed) is max. 10 bar, – which can give rise to condensation under certain circumstances, – which are declared by the manufacturer to be “condensing appliance”, – which are intended to be installed in a partially protected place, – which are intended to produce hot water either by the instantaneous or storage principle, – which have a maximum heat input (based on net calorific value) not exceeding 70 kW, – which are designed for sealed or open water systems. NOTE 1 For applications where the maximum allowable temperature exceeds 110 ºC or where volume multiplied by maximum allowable pressure exceeds 50 bar.litres, further requirements may be necessary to comply with the essential requirements of Directive 97/23/EC (Pressure Equipment Directive (PED)). NOTE 2 For mCHP appliances with constructions that might not be fully covered by this European Standard or by another specific standard, the risk associated with the alternative construction shall be assessed. This European Standard applies to type testing only. This European Standard does not contain the requirements necessary for appliance capable of producing electrical energy without using the thermal energy. |

| Normative reference (6) |
(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved
(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat
(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level
(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement
(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
