Saving Energy in Europe: 15 Good Practice Case Studies - Schemes for Energy Efficient Products: Incentives for Efficient Gas Boilers in Denmark

Share this Post:
The EEB has compiled a great showcase of different good practice case studies that will hopefully inspire similar projects all over Europe. In order to achieve our energy saving goals and reap the benefits that they offer, we can no longer afford to see these good practice schemes as isolated cases - as the ‘select exemplary few’. These case studies should be replicated, expanded, developed and deepened so that these approaches become the norm, every day practice - not the alternative. This Good Practise Case Study demonstrates how energy saving incentives/schemes introduced at different levels (state, borough, city etc.) can result in reduced energy use.


Aims and Objectives:   To help new, more efficient boilers penetrate the market and break through the first cost barrier and to increase their share of the boilers market from 15% to 33%.

Implementation Timeframe:

1999 – 2001

How it Works: 

A subsidy scheme was introduced in 1999 to improve the market share of gas fired condensing boilers. The Danish Energy Agency gave a bonus of 2.500 DKK (€335.21) or a rebate of the same amount for purchases of a new condensing gas boiler.


In 1999, before the scheme began, the percentage of condensing gas boilers on the market was between 10 and 15%. By 2000 the Danish Energy Agency reported that the percentage had grown to 35%. Although the scheme was closed in 2001 due to budgetary limits, the market share of gas fired condensing boilers had reached over 50%. The percentage kept growing until the sold gas boilers in Denmark today account for 100% of the market. This share persisted because the retail sector accepted condensing boilers and became familiar with them. They have also continued to recommend this boiler technology to home owners.

Key Benefits:

Market share of condensing gas boilers: 

  • 1999:  between 10% and 15%
  • 2000:  35%
  • 2001:  50%

Lessons learnt

This scheme for condensing boilers shows that once an economically viable energy efficient product is established on the market, the removal of the scheme does not necessarily mean a reversal in the purchasing numbers of the product. Dynamic schemes for efficient appliances together with ambitious ecodesign requirements are essential to hasten an increase in the uptake of efficient products. The Ecodesign Directive is not delivering as much as the Energy Efficiency Plan (2011)25 seems to assume. There have been numerous delays on the finalisation of product requirements and 2010 was a disappointing year for ecodesign policy implementation in the EU. We must grasp the full potential of energy efficiency and related savings from the ecodesign of energy using products. Ecodesign requirements need to show ambition and challenge industry to move from business as usual.
