Achieved Results and Impacts

Achieved results 

The main achieved results are:

  • Successful realization of the stainless steel cavities with the new coating.
  • The new coating avoids the use of toxic substances, such as nickel and cobalt cointained in standard enamelling.
  • HEO highly resistant to thermal stress test and mechanical tests (> 5H on pencil test) cavities.
  • HEO requires far less cleaning chemicals with respect to the state-of-the-art enamels ovens.
  • Life Cycle Analysis (LCA) and Life Cycle Costs performed successfully (preliminary and real-life).
  • Realization of a pre-production pilot line.
  • Preparation of a technical functioning report containing the blueprints of the pilot line, description of its functioning and flows, and trials results.
  • Pre-production pilot line tested, validated and working flawlessly.
  • 50 cavities and 12 complete prototypes realized.
  • 63 % energy saving of the pre-production pilot line with respect to state-of-the-art enamel plants as results of tests and trials.
  • Confirmation (on European products and according to EN 50304:60350 (2009) ) of an effective ≈30% energy saving, as result on the tests on the cavities.
  • HEO is compliant to A++ energy class.
  • Assembled prototypes fully code compliant (temperature, condensation and packaging tests were successfully done).
  • Energy to cook standard food evaluated on average 20% less in comparison to a black enamelled cavity.
  • Life test performed (5 years of product simulated): performance were guaranteed over time.
  • Full Market analysis performed, with two impact scenarios (EU and worldwide).
  • The activities carried out and the results achieved during the HEO project actively disseminated.

Impacts on EU policy and the everyday life of the European citizens

  • The savings in the global warming potential (GWP) from the HEO relative to conventional ovens range from 9%-61% over the oven lifetime (19 years), depending on the assumptions.
  • The equivalent savings in the life cycle costs range from 41%-61%.
  • At the EU28 level, the replacement of conventional domestic electric ovens by HEO would lead to save from 0.5-5.2 Mt CO2 eq./yr and from €0.5-1.96 bn/yr.
  • Assuming an uptake rate of 5% per annum, it would take 20 years to achieve these benefits.
  • The new coating allows to avoid toxic substances contained in standard enamel. This result, may contribute to improve human health and reduce welfare costs in EU28.
  • As a result, policy makers should consider measures to encourage the uptake of energy efficient ovens, including financial incentives and ‘choice editing’ through legislation.
