How to find and use certified heat pump data

We may live in the information age, but that doesn’t always mean the information we receive is easy to use, extract or compare. This can be a case in point when dealing with technical data for HVAC products such as heat pumps. Often the data available in manufacturer supplied datafiles can vary in comprehensiveness from manufacturer to manufacturer, leading to gaps in information. Or vital data can be presented in a PDF file, making it hard to extract. Crucially, information is often available in isolation, adding to the work to directly compare product attributes. No one wants to work with data that’s frustratingly time consuming to view, manipulate or export.

That’s where Eurovent Certification’s Certified Product Directory can be a vital tool for decision makers. Providing an excellent source of complete, comparable, trustworthy and easy-to-handle data, that’s downloadable in handy format. In this article we are going to explore the Certified Product Directory with a focus on heat pump data. We will examine how to access the tool, what information it holds, and guide you through how to view and download data and certificates.

What is the Certified Product Directory?

The Certified Product Directory is one of the largest HVAC and refrigeration databases in the world. Including only products certified by Eurovent Certification, the online database offers accurate performance data for over 40 different certification programmes. Data is provided across five core certification schemes including Eurovent Certified Performance, NF, QB, KEYMARK and MCS.

Heat pump data is split across five different programmes:

• Eurovent Certified Performance for Heat Pumps (Eurovent-HP)
  For electrically driven, gas absorption and gas internal / external combustion engine driven heat pumps.
• Eurovent Certified Performance for Chillers and Heat Pumps (LCP-HP)
  For hydronic heat pumps used for heating, air conditioning and refrigeration applications, which are equipped with any type of electrically driven compressor.
• Heat Pumps NF (NF414)
  For electrically driven, gas absorption and gas internal / external combustion engine driven heat pumps.
• Heat Pump KEYMARK (HPKM)
  For electrically-driven heat pumps, hybrid heat pumps, combination heat pumps and hot water heaters.
• MCS for Heat Pumps (MCS007)
  Aimed at heat pumps sold in the UK market, the programme covers electrically driven and gas absorption heat pumps up to a 45 kW output.

The directory is regularly updated and available online 24/7, 365 days a year.

What is certified data?

Certified data is data you can trust. Manufacturers voluntarily commit to have their products independently tested and data thoroughly evaluated by a third-party certifier. With crucial performance data impartially validated, products are guaranteed to perform as advertised.

While requirements vary from scheme to scheme, heat pump certification includes independent laboratory tests, factory audits, software checks and data evaluation under strict protocols. Eurovent Certification also runs a surveillance process to ensure products continue to comply with certification standards.

What heat pump information does the directory hold?

Note: Certified data can vary from product to product and programme to programme e.g. a reversable heat pump with domestic hot water (DHW) capabilities will include performance data for heating, cooling and DHW. A heating only HP will provide performance data for heating only. Therefore, not all programmes or product types will include the certified data below. Additionally, data can be verified across different conditions depending on product type.

Heat pump certified data can include characteristics such as:

Acoustic characteristics

These characteristics verify the noise output of the unit, which is especially crucial for residential applications or sensitive sites.

A-weighted sound power levels are chosen because they reflect the human ear’s sensitivity to different frequencies. By controlling and certifying these parameters, manufacturers and system designers can limit unwanted noise, prevent acoustic complaints, and ensure compliance with building codes and local ordinances.

In heat pumps, balancing thermal efficiency and low acoustic emissions is essential for user satisfaction and social acceptance of sustainable HVAC technologies. High noise levels can negate the benefits of efficient heating and cooling, particularly in dense built environments.

Seasonal heating characteristics

These characteristics are vital to selecting correctly sized, energy efficient systems for heating and have direct impact on the cost. They ensure the heat pump can meet demand in both worst-case and intermediate scenarios and quantify backup energy needs and idle losses.

Seasonal heating efficiencies reflect a more accurate real-world OPEX.

Collectively, these metrics provide a holistic view of heat pump systems in terms of capacity, seasonal efficiency, real-world energy consumption, and regulatory classification. Engineers rely on this data for system selection, energy modelling and optimisation. High accuracy and standardisation ensure building owners and occupants benefit from reliable, cost-effective, and environmentally sustainable heating.

Without these standardised values:

• Undersized systems may not provide sufficient comfort.
• Oversized systems operate inefficiently, increasing costs.
• Unquantified standby losses distort actual savings.
• Lack of classification impedes market transparency and policy implementation.

Heating characteristics

These characteristics are required to select correctly sized, energy efficient systems for heating, that are suitable for the local climate and deliver the desired comfort.

They are also essential for accurate cost forecasting. They enable designers and engineers to align heating output with building demand, define backup strategies, comply with regulatory requirements, and optimise integration with hybrid or renewable systems. Without precise values for these parameters, evaluating real-world performance, predicting seasonal efficiency, or identifying improvement opportunities would be impossible, ultimately undermining both economic and environmental objectives in building heating systems.

Seasonal cooling characteristics

These characteristics are vital to selecting correctly sized, energy efficient systems for cooling and ensure regulatory compliance.

These values give a better reflection of summer energy costs or thermodynamic efficiency without the influence of standby or off-mode energy use. They determine the system’s ability to meet peak cooling demand without oversizing, which can lead to excessive cycling, energy waste, and poor humidity control.

Cooling characteristics

These characteristics ensure adequate summer comfort and energy efficiency for reversible systems. They serve as baseline value for comparisons across units and are required for calculating critical efficiency ratios. They are often part of mandatory efficiency thresholds in HVAC product standards.

Domestic hot water characteristics

These characteristics are vital to ensuring DHW capacity, consumption and safety needs (e.g. combatting Legionella) are met in the most energy efficient manner and confirm compliance with standards like EN 16147, facilitating market access and reliability in claims.

They reflect how effectively electrical energy is converted into usable hot water heat, ensure testing replicates realistic scenarios and system sizing meets demand spikes without excessive waste. They also enable a technically rigorous evaluation of domestic hot water heat pump systems, supporting informed decision-making.

Gas driven HP characteristics

These characteristics are required to select correctly sized, energy efficient gas driven systems for heating.

They reflect how effectively the heat pump converts fuel gas into useful heat output during realistic seasonal conditions, account for the total energy footprint of the heat pump system and align with regulatory frameworks focused on primary energy consumption and sustainability goals. They are useful for comparing gas heat pumps with other heating technologies on a consistent energy basis.

Part load operation characteristics

Heat pumps rarely operate at full load continuously; much of their annual runtime occurs at partial or low loads. Lrcontmin provides information on lowest part load at which operation is still possible without cycling on/off. It indicates how efficient the heat pump is and how well it can modulate its output under at very low continuous load conditions. This data is required for all constructions falling in the scope of RE2020.

General characteristics

General characteristics verify information on the system set up, including aspects such as number of indoor / outdoor units, refrigerant, power supply and compressor. To view the characteristics for each programme and product type, please refer to the Certified Product Directory or visit the programme page.
