[...] Gas cooktops Induction cooktops Gas ovens Electric ovens 4 We estimated the number of appliances installed per year • Estimation based on source data and stock numbers from Residential Baseline Study • ~940,000 gas appliances per year • ~800,000 resistive electric appliances per year Source: IEEFA analysis of sources from EnergyConsult 2021. [...] Expanding GEMS to cover a broader range of appliances • Some products in our analysis are already subject to GEMS determinations: • Air conditioners (including reverse- cycle) • Electric water heaters (excluding heat pumps) • Gas water heaters • However others are missing: • Gas space heaters • Electric resistive heaters • Heat pump hot water systems • Cooktops 13 2. [...] • Some gas appliances are currently excluded from GEMS • Electric un-vented • Gas storage water • Others are included in separate displacement water heaters determinations from electric heaters • Gas instantaneous • Electric vented water heaters appliances displacement water heaters • Structuring determinations • Electric heat exchange water heaters around a single end-use could enable a direct co.
