Our Exclusive Pre-Wired Controllers Save you Time and Money

Rheem’s innovative tankless water heater remote controllers make it simple to know and adjust your unit’s water temperature. However, these remote controllers have to be wired properly with the unit to work. We are the only Rheem retailer whose units come with pre-wired remote controls. All other new Rheem tankless water heaters for sale online and off require an expensive electrician to wire them. This wastes time and is expensive. Buying your new Rheem on-demand instant on and endless hot tankless water heater from us with a pre-wired controller, will save you time and money on your unit’s installation.
