Heating Brochure 2021

PRODUCT LABEL
There are two different classifications for central heating
and domestic hot water; for products which can provide
both services, labels must show both the classifications.
There are dierent labels, depending on the type of
product and service guaranteed. The eciency classes A,
A+ and A++ indicate the products with higher performance.
In addition to the energy class, the labels display
information to help consumers choose the most
ecient products with less environmental impact.
SYSTEM LABEL
All units that are combined with others as
part of a system must have a secondary
label in addition to the product label and
technical documentation to show the
system performance.
The installer will be responsible in
defining the overall system performance
(through an automatic algorithm) and
must fill out the label accordingly.

Minimum performance requirements for
space heating and domestic hot water
production
Since 26 September 2015, the new European Union regulations define minimum eciency and energy labelling
requirements for boilers, heat pumps, water heaters and hot water tanks.
From 26 September 2018, new limits for NOx emissions were introduced in addition to the eciency limits already
in force. The NOx limits have been applied to products placed on the market starting from 26 September 2018.
Products purchased before that date and already in retail outlets or distribution warehouses can continue to be
sold and installed, even though they do not comply with the new requirements.
In 2019, the UK became the first major economy in the world to pass legislation to end its contribution to global
warming by 2050. A target was set requiring the UK to bring all greenhouse gas emissions to net zero by this date.
