Overview for Rinnai RE199IP
Rinnai is raising the bar in tankless heating technology with their RE Series tankless water heaters. The RE199iP and all the RE Series models offer the perfect combination of comfort and value, with the performance you can only expect from Rinnai. With a 0.82 Uniform Energy Factor and a sleek innovative design, the RE199iP is a practical alternative water heating choice that is easily maintained.
Continuous Water for Multiple Applications
Rinnai tankless water heaters provide an endless supply of hot water that remains uninterrupted, even when you’re the last one in line for the shower.
Energy Efficient Promise
Tankless water heaters avoid the need to keep a large amount of reserve water heated at all times. This saves energy by only heating water when you need it, while an entirely electric ignition avoids the constantly wasted energy of a standing pilot light.
Wi-Fi Compatible
Every RE Series water heater is Wi-Fi compatible for remote monitoring and management.
Compact Design
The RE199iP is designed to be able to be installed on any wall or in any compact space, including non-traditional places like an attic or crawlspace that hides your unit and frees up valuable space. Rinnai tankless water heaters are perfect for any home.
