In these tankless water heater for pets reviews we score four heaters for home pet wash stations: two electric point-of-use units for indoor tubs and two outdoor propane units for backyard or barn rinsing. We looked at how steady the temperature stays, how much flow a sprayer gets, how easy they are to install and how safe they are around animals.
All four were scored on the same criteria using manufacturer specifications and owner feedback. For our shortlist see the best tankless water heater for pets guide; our Editorial Policy explains how we work. Outdoor propane units must only be used outdoors.
