Commission Decision of 28 May 2014 establishing the criteria for the award of the EU Ecolabel for water-based heaters (notified under document C(2014) 3452) (Text with EEA relevance) (2014/314/EU)

Criterion 5 — Carbon monoxide (CO) emission limits U.K.

The carbon monoxide (CO) content of the exhaust gas shall not exceed the limit values indicated in Table 12 (not applicable to electrical heaters). CO emissions shall be measured at the following operating conditions:

• Gas and liquid heaters, at standard rating conditions and rated heat output

• Solid fuel heaters, as seasonal space heating emissions according Table 4.

The unit of measurement shall be given in mg/kWh GCV energy input or in mg/Nm³, as appropriate.

Table 12

CO emission limits by heat generator technology

Heat generator technology	CO emission limit
Gas heaters	Equipped with internal combustion engine: 150 mg/Nm3 at 5 % O2 Equipped with external combustion: 25 mg/kWh GCV energy input
Liquid fuel heaters	Equipped with internal combustion engine: 200 mg/Nm3 at 5 % O2 Equipped with external combustion: 50 mg/kWh GCV energy input
Solid fuel heaters	Automatically stoked: 175 mg/Nm3 at 10 % O2 Manually stoked: 250 mg/Nm3 at 10 % O2

Assessment and verification: U.K.

A certificate signed by the manufacturer declaring compliance with this criterion shall be submitted to the awarding competent body, together with the relevant documentation.

The CO emissions in the exhaust gas shall be determined as standard emission factors according to the relevant standards included in Table 2 and Table 3 (where applicable).
