The Rheem RTG-53PVP liquid propane tankless hot water heater supplies 1-2 major hot water applications at a time. Unit can be vented either through the wall or roof and can be connected in series to increase hot water flow. The RTG-53PV tankless hot water heater can supply 5.3 gallons per minute of hot water at a 45 degree temperature rise. It requires a 3" stainless steel exhaust vent and utilizes the air within the room where the water heater is installed for the combustion air (note: consult the user's manual to determine if steps need to be taken to ensure the combustion air requirements are met). This tankless water heater carries a 10 year limited warranty on the heat exchanger and a 3 year limited warranty on parts. The ignition is electronic and the unit comes with a 120V power cord.

This model can be linked with another RTG-53PV in series with the EZ-Link cable (RTG-20040) for high demand applications as the two units would operate as one with double the water flow. When 3 to 20 units are connected in series a manifold controller, cables and/or control boards are required.

The RTG53PVP tankless hot water heater model differs from the RTG53DVP in that it has an internal combusion air setting and does not require a 2nd hose to pull air from the outside.

This model only accepts 3/5" concentric stainless steel venting.
