The Rheem RTG-70DVLN-3 is an indoor, natural gas, non-condensing tankless water heater from Rheem's RTG series. It is built for one-person installation and service, with a smaller, lighter body than earlier RTG units. Hot-Start Programming reduces the cold-water burst between back-to-back draws, and the 43 ft vent run gives installers more placement freedom than many rivals. It meets SCAQMD Rule 1146.2 low-NOx rules, so it suits strict air-quality areas. It is a good fit for households replacing a tank heater that want endless hot water without a condensing unit's drain line.
