A range means the models under one basic model differ. A dash means the model has no such figure.

Per unit of energy, its heat into water, or UEF, reaches 4.00. That UEF is over 1 because heat pumps move heat from air into water. The US3-RSJ-15/300RDVN3-L3 is the one basic model of this brand with that UEF. Not one of its basic models lacks an ENERGY STAR certified model.

This brand lists 2 kinds: gas tankless and heat pump. The gas tankless group holds 6 of its 9 basic models. Its first-hour peak, 91 gallons, comes from the US3-RSJ-15/300RDVN3-L3. Those 91 gallons include water the tank heats while the hour runs. Of this brand's tankless models, 4 share the highest flow. That flow is 5.7 gallons per minute for water warmed by 67°F.

On this site, 47 of the 117 brands list more model numbers than Kepler's 10. Each of 8 other brands shares at least one basic model number with this brand. Of those, Midea lists the most: 6 of this brand's 9.
