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 European Commission provides tools for generating energy labels for products on the EU market.
Ecodesign requirements for solid fuel boilers with a rated heat output of 500 kW or less will be 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.
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.
