Selection Criteria Local Space Heaters

Methodology

Topten.eu presents the most energy-efficient local space heaters of Europe. Topten shows models which use wood pellets, logwood or both.
Note that wood boilers (solid fuel boilers for central heating) are not part of this list.

Regulations

Energy Labelling Regulation EU 2015/1186

For local space heaters, energy labels are mandatory since January 1st, 2018, indicating the energy efficiency class on a scale from A++ (most efficient) to G (least efficient) . The label provides information such as the brand, the model, the energy efficiency class, the direct and - if applicable - the indirect heat output in kW, which measures the heat transferred to a liquid (for hot water or for a central heating system). The energy label is mandatory for appliances with rated output up to 50 kW.

Energy efficiency classes for local space heaters have the following thresholds:

Energy efficiency class

Energy efficiency index (EEI)

A++

EEI ≥ 130

A+

107 ≤ EEI < 130

A

88 ≤ EEI < 107

B

82 ≤ EEI < 88

C

77 ≤ EEI < 82

D

72 ≤ EEI < 77

E

62 ≤ EEI < 72

F

42 ≤ EEI < 62

G

EEI < 42


Ecodesign requirements EU 2015/1185

The Ecodesign regulation is valid for appliances with a rated output up to 50 kW. The minimum requirements will become legally binding on January 1st, 2022. Minimum requirements are specified for the following criteria (cf. Table 4):

  • energy efficiency (criteria is the seasonal space heating energy efficiency)
  • emission of particulate matter
  • organic gaseous compounds
  • carbon monoxide
  • nitrogen oxides

In addition, a product fiche with additional information will become mandatory on January 1st, 2022.

Glossary

  • Brand: specifies the brand of the presented stove
  • Model: specifies the name/number of the presented stove
  • Similar models: specifies names/numbers of similar stoves (different colors, material, but essentially the same model)
  • Energy Label: specifies the current European Energy label as specified in EN 2015/1186. The label ranges from A++ to G.
  • Fuel type: Specifies the fuel that can be used in the stove. This can be either Pellet, Logwood or Pellet+Logwood.
  • Heat distribution: Specifies the type of heat distribution this stove provides. The attribute values can be one or several of the following: None, ventilation, automatic storage mass, water pocket, central distribution system
  • Weight (kg): Specifies the weight in kg. For example, 181.
  • Height (cm): Specifies the height in cm. For example, 104.
  • Width (cm): Specifies the width in cm. For example, 68.
  • Depth (cm): Specifies the depth in cm. For example, 38.
  • Max. heat output (kW): specifies the maximum heat output in kW.
  • Connected load boiler [kW]: specifies the electricity load for which the boiler is connected. For example, 2.
  • Energy Efficiency Index (%) : specifies the efficiency in % at the rated load, e.g. 107. The higher the EEI, the more efficient is the stove.
  • Refuelling system: specifies how the stove is refuelled. The attribute value can be one or several of the following: Manual, Screw conveyer, Pneumatic conveyer.
  • Auxiliary energy demand at nominal load (%): Specifies the additional energy demand in % for additional processes (such as refuelling, ventilation, controlling airflow, etc.).
  • Dust nominal load [[mg/Nm3]: specifies the particulate matter in the exhaust air at nominal load of the stove.
  • CO nominal load [mg/Nm3]: specifies Carbon monoxide in the exhaust air at nominal load of the stove.
  • C org nominal load [mg/Nm3] : specifies the organic Carbon in the exhaust air at nominal load of the stove.
  • NOx [mg/Nm3]: specifies Nitrogen dioxide in the exhaust air at nominal load of the stove.
