The HeatingSave products Systems are authorised by the UK Government on its Energy Technology List- an official endorsement and recognition that they meet the Government’s specific energy-saving or energy-efficient criteria. The Department for Business, Energy and Industrial Strategy (BEIS) annually reviews the technologies and products that qualify for inclusion.
