Solid Fuel Boilers

Energy labelling and ecodesign requirements apply to this product.

Solid fuel boilers are similar to central heating boilers. Their purpose is to heat multiple rooms by means of the transport of hot water through a plumbing system.

The difference is the input source, which are solid fuels instead of gas, liquid fuels or electric.

Scope

The following table shows some examples of products in scope and out of scope

In Scope Out of Scope
  • solid fuel boilers with a rated heat output of 500 kilowatt (‘kW’) or less, including those integrated in packages of a solid fuel boiler, supplementary heaters, temperature controls and solar devices are in the scope of the ecodesing requirements. The scope of energy labelling requirements is more restrictive in terms of rated heat output, applying to solid fuel boilers with a rated heat output of 70 kW or less and to packages of a solid fuel boiler with a rated heat output of 70 kW or less, supplementary heaters, temperature controls and solar devices
  • boilers generating heat exclusively for providing hot drinking or sanitary water;
  • boilers for heating and distributing gaseous heat transfer media such as vapour or air;

Check the complete list in the Regulation

Ecodesign Requirements

Ecodesign requirements for solid fuel boilers with a rated heat output of 500 kW or less are mandatory from 2020 onwards for all manufacturers and suppliers wishing to sell their products in the EU.

These requirements are also applicable to boilers that are part of packages consisting of a solid fuel boiler, supplementary heaters, temperature controls and solar devices. The requirements cover energy efficiency and air pollutant emissions.

Energy Label

New solid fuel boilers with a rated heat output of 70 kW or less are labelled on an energy efficiency scale ranging from A+++ (most efficient) to G (least efficient).

Energy labelling rules also apply to packages that include a combination of a solid fuel boiler, supplementary heaters, temperature controls and solar devices.

The Commission will review the existing rules on energy labelling for solid fuel boilers and launched on 28 September 2023 (with a deadline until 21 December 2023) a public consultation and a call for evidence to seek input from the public and from stakeholders.

Packages

Solid fuel boilers include packages. A package of a solid fuel boiler, supplementary heaters, temperature controls and solar devices means a package designed either by manufacturers or by installers containing a solid fuel boiler possibly also containing supplementary heaters, indoor temperature controls and solar thermal panels. Packages in EPREL are offered by manufacturers. Installers can also design packages on the basis of components available in EPREL.

Eco Tips and Tricks

  • Ensure consistent and uniform fuel feeding to optimize performance 
  • Optimize air intake to achieve better combustion efficiency 

Highlights

Solid fuel boilers are space heaters that generate heat through the combustion of solid fuels and use a water-based central heating system to distribute the generated heat to multiple rooms.

Efficient solid fuel boilers can save European consumers over €140 million annually by 2030. For example, replacing a conventional solid fuel boiler with a highly efficient solid fuel boiler can save up to €1 050 over the lifetime of the product.

In addition, ecodesign requirements for solid fuel boilers are expected to improve air quality in Europe and reduce related health problems.

Facts & Figures

This graphic shows the estimated sales, stock, energy consumption (primary, electric or fuel), greenhouse gas emissions, consumer expenses and business revenues for years 2010 and 2030. The estimated values inside the graph bars are those from the EIA ECO-scenario, they include the effects of ecodesign and energy labelling measures.  

The difference with the business as usual (BAU) scenario without these estimated measures is shown next to the graph bar. These figures indicate the estimated savings obtained due to the measures.

Expected Savings

The Ecodesign requirements and labelling promote improved product design by manufacturers. This will lead to products with higher energy efficiency.

Total primary energy savings of SFBs due to ecodesign and energy labelling requirements are 22 PJ/a in 2030.

EMISSIONS SAVINGS

In addition to minimum energy efficiency requirements, the regulations also set emission limits. Besides GHG emissions, SFBs emit organic gaseous compounds (OGC), particulate matter (PM) and carbon monoxide (CO). These emissions result from the incomplete combustion of fuel, due to a lack of oxygen or too low combustion temperature. Improved combustion technology can increase energy efficiency and reduce pollutant emissions.

The Ecodesign measures are projected to decrease OGC-emissions from 52 kt/a in 2015 to 45 kt/a in 2030 (-13% vs. no measures), PM-emissions from 40 kt/a to 35 kt/a (-12% vs. no measures), and CO-emissions from 614 kt/a to 540 kt/a (-12% vs. no measures).
