SCOPE OF THE PROGRAMME

The scope of the Keymark certification programme for Heat Pumps applies to heat pumps (HP) included in COMMISSION REGULATION (EU) No 813/2013 or 814/2013 of 2 August 2013, or COMMISSION REGULATION (EU) No 206/2012 of 6 March 2012.

This includes:

  • Heat pump space heaters providing heat to water-based central heating systems for space heating purposes, with heating capacities up to 400 kW
  • Heat pump combination heaters providing heat to water-based central heating systems for space heating purposes and heat to deliver domestic hot water, with heating capacities up to 400 kW
  • Heat pump water heaters, which are dedicated to providing domestic hot water, with heating capacities up to 400 kW
  • Air/air heat pumps up to 12 kW cooling capacity (or heating capacity for air/air heating only products), except single duct and double duct units
  • Hybrid heat pumps and hybrid combination heat pumps
  • CO2 heat pumps specifically designed for heating domestic water and which are placed on the market without a water tank
  • Air/air heat pumps included in the scope of REGULATION (EU) No 206/2012 of 6 March 2012 that also provide domestic hot water and that use outdoor air as a heat source.

PRODUCT TYPE

A heat pump can be used to heat, cool or produce hot water for buildings. A heat pump takes energy from the environment (air, water or ground), converts it into heat, and releases it at a higher temperature into a cold environment via air or water. Heat pumps can heat a building via an emitter such as radiators, underfloor heating or fan convectors. Certain heat pump models also produce domestic hot water (DHW) or heated water for use in swimming pools. Heat pumps can come in reversible versions, which are used to cool the indoor environment, like an air conditioner.

There are three different types heat pumps depending on the energy source:

  • Aerothermal (Air/Water; Air/Air) - The calories are taken from the Air (outdoor or extracted)
  • Geothermal (Ground/Ground; Ground/Water; Glycol water/Water; Glycol water/Glycol water) - the calories are taken from the Ground
  • Aquathermal (Ground water/Water; Circuit water/Recycled air) - the calories are taken from Water (groundwater). 

Hybrid heat pump systems combine heat pump technology alongside another heat source, usually a gas, oil or LPG boiler. The heat pump and boiler can be combined in a single unit, or the two heat sources can be independently installed. Hybrid heat pumps typically provide heating and hot water for residential properties.

A heat pump can come as:

  • A single unit (“single-unit”) installed outdoors
  • In two units (“single-split” or “split”) 
  • Multiple units (“multi-split”), in which the condenser is placed inside the medium to be heated.

Several types of heat pump systems can be certified within the Keymark Heat Pump certification programme. 

CERTIFIED CHARACTERISTICS

Depending on model type, the following quality criteria can be tested:

  • Space heating performance
  • Space cooling performance
  • Energy efficiency
  • Sound power level 
  • DHW performance
  • Operating performance.
