ICS Code (Fuel cells): 27.070
ICS Code (Gas heaters): 97.100.20
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, C42, C43 C52, C53, C62, C63, C82, C83 and C9 based on the classifications of CEN/TR 1749:

- that use one or more supplied gases of the three gas families at the pressures stated in EN 437,

- where the temperature of the heat transfer fluid of the heating system (heating water circuit) 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) does not exceed 10 bar,

- which are either intended to be installed indoors or outdoors 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 water 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 will be assessed.

NOTE 3 prEN 13203-4 will specify the assessment of energy consumption for domestic hot water production of gas combined heat and power appliances (mCHP).

This European Standard does not contain the requirements necessary for appliance capable of producing electrical energy without using the thermal energy.

This European Standard does not cover all the requirements for mCHP appliances that are intended to be connected to gas grids where the quality of the distributed gas is likely to vary to a large extent over the lifetime of the appliance (see Annex DD).
