RMTG-64DVLP - Direct Vent Automatic Indoor LP Gas Tankless Water Heater - 11,000 - 150,000 BTUs. Provides a hot water recovery rate of 155 gallons per hour. We purchased a couple years ago thinking our water heater had died and then found out ours just needed a new igniter so it’s been sitting in our basement on a table. Ready to sell because our original heater seems to be holding up fine.
