The days of icy cold showers are over! With the Rheem Tankless Water Heater RTG74PVN, showers start hot and stay hot for as long as the shower is running, plus the system is much smaller than normal tank water heaters and uses much less energy.

The Rheem RTG74PVN is an Indoor unit powered by Natural Gas that turns on when you open a hot water faucet and turns off when you close the faucet, so the energy consumed is only for the hot water being used. Since there is no storage of hot water and thus no constant heating and re-heating of stored hot water, you're not wasting energy heating water when you don't need it.

Key features include: 7.4 gpm at a 45ºF temperature rise; electronic ignition to increase efficiency; remote control thermostat; digital temperature display; built-in electric blower to force exhaust gas outside; environmentally friendly low NOx burner; and a 3-year limited warranty on parts (10 years on heat exchanger.)

The Rheem Tankless Water Heater RTG74PVN is a revolution in home water heating that provides instant gratification with the satisfaction of being environmentally friendly and cost efficient at the same time!
