The Rheem RTG74DVP (Liquid Propane) direct vent liquid propane tankless hot water heater supplies 2-3 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 RTG74DVP tankless hot water heater can supply 7.4 gallons per minute of hot water at a 45 degree temperature rise. It requires a 4" stainless steel exhaust vent and with the direct vent is able to pull in air through an intake vent(can be PVC, aluminum flex, etc) to eliminate the combustion air requirements. This tankless water heater carries a 12 year limited warranty on the heat exchanger and a 5 year limited warranty on parts. The ignition is electronic and the unit comes with a 120V power cord.

Note: This model can be linked with another RTG74DVP 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. For installations above 3,280 ft a high altitude chip is required.
