The Rheem 9.5 GPM Performance Platinum Super High Efficiency Indoor Liquid Propane Smart Tankless Water Heater delivers more hot water than most tank water heaters. The 199,900 BTU Super High Efficiency Liquid Propane Tankless Water Heater can provide enough on demand hot water to supply up to 3 bathrooms at the same time (at a 35? water temperature increase). It's also more efficient than most traditional tanks; it's up to 52% more efficient than a standard 50 Gal. gas tank water heater. This model has a 0.93 Uniform Energy Factor (UEF), which means it may qualify for local utility rebates and incentives. Plus, this is a smart tankless model; built-in Wi-Fi Technology provides valuable alerts and control from anywhere with a smart phone. The Platinum's venting allows for it to be installed in many locations and it uses PVC for venting enabling an easier installation and reduced installation time; easier installs are just one of the reasons Rheem Tankless Hot Water Heaters are preferred by contractors.
