Energy label

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

The regulations set ecodesign requirements on:

  • energy efficiency
  • nitrogen oxide emission levels
  • volume for storage water heaters
  • heat losses from hot water storage tanks

Energy savings

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.
