Ecodesign
Many times you could hear about dozens of advantages of class 5 boilers – they are, among others, energy-saving, cost-effective and highly efficient. However, the European Union decided to go a step further and prove that boilers can be even better. This provision was included in the Ecodesign Directive, also known as the Ecodesign or ErP Directive. Solid fuel heating boilers are included in the EU Commission Regulation 2015/1189 of April 28, 2015.
Ecodesign is to come into force only at the beginning of 2020, but it is worth getting acquainted with the basic changes it is to introduce today. What for? Ecodesign is the EU’s answer to the problem of very short operation of the device at nominal power – this means that the boiler is energy efficient only for a small part of the season. After its expiry, it operates in standby or standby mode, which is unfavorable both in terms of costs for the user and in the environmental aspect regarding exhaust emissions.
The Ecodesign Directive introduces new requirements that all boilers will have to meet in 2020. The remaining models will be permanently withdrawn from sale. Above all, the issue of seasonal space heating emissions is important.
Main assumptions:
Seasonal energy efficiency cannot be lower than 75% for boilers with a nominal power of 20 kW or less, and 77% for boilers with a nominal power exceeding 20 kW. The directive also specifies requirements for the emission of carbon monoxide, nitrogen, organic gaseous compounds and particulate matter. Boilers that meet all these requirements will receive a special label emphasizing that it is this device that will be the most beneficial for the owner and the natural environment.

5th class
Several years ago, three basic emission classes of boilers were distinguished – from 1 to 3 (best/highest), which was defined in the EN 303-5 standard from 2002. However, within 10 years, new regulations were prepared, which were included in the updated standard in 2012. They presented three new classes with more stringent emission conditions: from 3 to 5, where 5 is the most restrictive and therefore the best class.
It is worth noting that many older models of boilers still do not have any class on the rating plate, because it was not required before. Only people trying to obtain a subsidy for the purchase of a boiler tried to obtain it. However, the new standard already enforces the marking of a class on each boiler, according to their degree of harmfulness to the environment.
What conditions must be met?
In order to receive a rating plate with class 5, the boiler must meet very restrictive conditions, which are specified in the EN 303-5:2002 standard. These include, among others:
Boilers marked with the Class 5 plate must meet very restrictive requirements.
These are very large changes, forcing manufacturers to use much more advanced technologies, as well as more restrictive instructions regarding the fuels that can be burned. These include, above all, dry fuel, which can also be dried independently through ventilation in the device.
The new regulations have been in force since October 1, 2017. This means that each boiler manufactured after this date must comply with the 5th class emission requirements. This involves an increase not only in the prices for the device, but also for the allowed fuel.
