Eurovent Certita Certification
The main Certification Contributors
In a European context where current or future regulations, such as those on eco-design, are effectively based on the declaration of product performance by the manufacturers themselves, voluntary certification provides reliable product data, and helps organise the market.
The publication of certified performance by an independent and accredited body ensures that the design offices, installers, and users in general have a consistent, reliable, and continuously up -o-date database at their disposable, and manufacturers to enhance the best features of their products.
In a highly competitive market, product certification plays a key role in ensuring fair trade and establishing trust between operators.
In addition, transparency and availability of certified performance constitutes a very effective tool in promoting new product development and ever more effective technical solutions. Either directly when the certification standards introduce performance thresholds, or only indirectly through free competition. Over the years, it was possible to observe a steady increase in COP values for certified heat pumps.
Finally, it should be noted that certifications, such as those granted by Eurovent Certita Certifications, are developed closely with the professional sectors involved, which ensures consistency with market expectations and developments. Examples include the introduction, in consultation with AFPAC, in the size certified characteristics and the acoustic specifications relating to heat pump noise. Researching consistency with market expectations also signifies anticipating future developments in support of manufacturer and industrial developments. In particular, this is what is implemented in the NF PAC and Eurovent Certified Performance certifications, as the application of Eco-design regulations will dramatically shake up the current situation.
Since 2013, the trademarks “Eurovent Certified Performance” (Figure 1), “NF PAC - Heat Pumps” (Figure 2) and “NF Multi-Energies” (Figure 3) have been issued by a single certification body: “Eurovent Certita Certification” [1, 2]. These trademarks, which have an impact on French and European level and are also globally renowned, cover all types of heat pumps in their various functions, a scope which is described later in this document. In a complex context, where the thermal regulation of buildings RT2012  specific to France, in addition to regulations on marketing products with European texts that are gradually being written, certification will showcase in a more understandable manner energy efficient products to prescribers and final users, products which have an acceptable acoustic performance. The development of this trademark certification is presented below.

Current status of heat pump certification
October 2014, marked the 20th anniversary of Eurovent Certification activities. On the other hand NF exceeded its thousandth heat pump certification, and a new reference document appendix for the Multi-energy standard dedicated to hybrid systems is available, which combines heat pumps and boilers. On this occasion we can review the road we have gone down and the status on the current type and number of certified reference documents. (Table 1).

Faced with market statistics available from Eurovent Market Intelligence and Clim’Info, this data support the assertion that the coverage of certified Heat Pumps on the European market is very high.
From “Standard” performance to “Seasonal” performance
Energy performance characterisation for eat pumps is gradually migrating from EER and COP nominal performance EN 14511 ) to seasonal performance (EN 14825 ), whose recent developments, and those to come, will cover more and more types of products.
Whilst the industry has implemented ESEER (European Seosonal Efficiency Ratio), certified since 2007, recently published regulations or those in the process of being published talk about seasonal coefficient of performance (SCOP) in heating mode, and its equivalents SEER and SEPR in cooling mode (see Table 2).
In order to compare the heating solutions between different technologies, the seasonal effectiveness is defined in primary energy etas (ηs). In order to respond to these developments, Eurovent Certita Certification suggests that manufactures certify this new performance. Since the 2013 revision of the reference document “AC1” (Air Conditioners ≤ 12 kW - Luxury Air Conditioning Units), manufacturers are required to declare the SEER, covered by eco-design 206/2012  and labelling 626/2011  regulations. Products which do not fall within the thresholds of the regulation are excluded. Since revision 8 of the reference document NF PAC published in the autumn of 2014, manufacturers can certify SCOP and seasonal energy efficiency for the heating premises ηs, covered by regulations 813/2013  811/2013 , as an option. Since the 2015 revision of the reference document LCP-HP (Liquid chilling packages and heat pumps), published December 2014, manufacturers are required to declare the SCOP and ηs, data that will be published in the autumn of 2015.
In the 2016 or 2017 revision of the reference documents AC2, AC3 (Air-Condition Units<=100 kW) and RT (Rooftop Units), manufacturers shall declare the SCOP, SEER and/or the etas, knowing that the regulation was passed in April 2014 but the unreleased documents have not been published in the official EU journal yet, and the mandate to meet the harmonised standards on the needs and regulatory testing methods is in its early stages.
Sanitary Hot Water
Present in the source document NF PAC since August 2012, the certification of dual service heat pumps producing hot sanitary water evolved in its 7th revision, which was published at the end of June 2014 to ensure the further certification of heat pumps and storage tanks with a reference simulation tool.
Regarding future developments, a work group has been meeting since September 2014 to introduce by the summer of 2015, the possibility of certifying collective sanitary hot water, with or without the 2000L capacity limit.
A new and truly European certification for heat pumps
The “European Heat Pump” certification program is a bridge between the NF programme and the ECP trademark. The first certificates shall be distributed at the beginning of 2015 and the data shall be available online at the end of winter.
Concerning the NF Multi-Systems trademark, it does not concern the enhancement of each component, but the enhancement of the system’s performance as a whole.
The first appendix of the multi-energy reference document is dedicated to hybrid heat pumps (hybrid heaters). In this case specifically, it concerns the enhancement of the performance regulation system that can be optimised in such a way so as to use fossil fuels or electricity in the most favourable conditions during the key operating points of the product. It can also be for consumers using electricity during off-peak rather than peak periods.
The first certificate was published in November 2015. The trademark committee also addressed it in 2014 to introduce seasonal performance in certified data in 2015 or 2016, while the taking into account these systems in the EN 14825 standard has not been resolved in the next version of the standard, but is in the process of being defined in the following version.
To promote the most environmentally friendly products, the Eco-Label Directive  completes the eco-design and labelling guidelines. For heat pumps, the criterion for the attribution of the co-label, initially published 9 November 2007  and valid until 31 October 2014, were updated by the decision of the committee’ dated 28 May 2014 . Note that the eco-label had been attributed to a handful of product lines in France, Belgium and Germany.
An extension of the scope of the text on hybrid devices is amongst the latest advances, including the emergence of a Total Equivalent Warming Impact (TEWI), based on the Global Warming Potential (GWP) of the refrigerant used with conventional end-of-life leakage rate fixed at 35% and the seasonal energy effectiveness for the heating of premises ηs.
In a changing regulatory and normative context, the offer of certification by Eurovent Certita Certification may be adapted to the heat pump market, therefore ensuring a guarantee to the final client a better understanding of performance thanks to the collaborative work including all stakeholders, while covering as extensively as possible existing solutions and technologies.
