Space and water heaters in households are subject to EU energy labelling and ecodesign requirements. Energy efficient household space and water heaters can save European consumers over €60 billion by 2020. For example, if your home is equipped with a conventional gas boiler using 20 MWh of energy per year, a new condensing gas boiler can save you €275 per year. A new boiler will pay back its original cost in just seven years while also reducing your energy consumption by more than 20%.


Energy efficient space and water heaters could save 600 TWh of electricity per year, avoiding the emission of 135 million tonnes of CO2.


Energy Labels 

A new space or water heater comes with an energy label showing its energy efficiency class. For individual products, ratings go from G (least efficient) to A++ (most efficient). It is also possible to buy a combination of technologies, such as a boiler with a solar hot water storage tank, in order to reach an A+++ energy efficiency rating.


Ecodesign requirements are mandatory for all heater manufacturers and suppliers wishing to sell their products in the EU. The regulations set requirements on energy efficiency, nitrogen oxide emission levels, volume for storage water heaters, and heat losses from hot water storage tanks.
