General Electric water heaters that are using tankless technology are the latest addition to the GE heating group, used for continuous hot water flow, for residential on demand heating.

All GE tankless water heaters are using natural gas or LP gas, vented out and based on the installation feasibility you can buy direct vent units, with an inside or outside installation and with a multiple unit installation for higher demand homes.

general electric water heaters have a new addition, a tankless technologyKeep in mind that some of the gas-fired General Electric water heaters are factory set for natural gas, while other on LP gas. If the unit is factory set to use the natural gas, it is very easy to convert it to propane gas and vice versa. Gas conversion should be done by the qualified technician.

All tankless heaters from GE that come with the energy factor of 0.87 or higher are Energy Star compliant. They are also "green", actually using the "green" technology to reduce the emission of NOx, greenhouse gases.

Reviewing the basic features

General Electric water heaters that are using tankless technology are designed and built by Rheem manufacturer, so if you compare both tankless brands you will notice that there are no significant differences between them.

GE tankless water heaters are manufactured by this well-known company, which means than only quality gas heaters are in the offer, together with the component parts and available features.

All tankless General Electric water heaters are designed for residential water heating, from small homes to the multiple bath homes with larger demands. With its compact design, GE tankless water heaters are designed for installation on the wall, so they free up floor space and provide versatility and flexibility when choosing the right location.

GE tankless appliances are providing hot water to use it for showers, for dishes, washing the clothes, even the tub... as they provide the endless supply. There is no tank, no water storage, the unit works only on demand. Such a demand-run technology allows you to always have fresh water coming out of the unit while heating costs are reduced by at least 25%.

General Electric tankless water heaters, designed for the outside installation, have the freeze protection which is consisted of the ceramic heaters located inside the unit, so it can protect the unit from freezing outside weather and as low as the temperature of -30 F.

The central component, which is the brain of the GE tankless water heater, is the electronic board. Electronic digital control is used to set and control the hot water temperature and provide diagnostic codes for easier troubleshooting and maintenance.

The temperature of the outgoing hot water is, thanks to the advanced technology, constantly monitored. This technology allows the heater to adjust the water flow to maintain desired temperature. These GE tankless units are providing a temperature range from 98 F to 140 F. If you want even better control of the water temperature and monitor heater's operation, recommendation is to install a remote control (indoor units only).

GE tankless heaters are not using the pilot light, but direct electronic ignition, which helps in boosting the energy efficiency. Maximum gas input is found on 9.4 gpm models, and is 199,000 BTU per hour if the unit is using natural gas, and 190,000 BTU if using propane or LP gas. For 7.5 gpm models, gas input is 180,000 BTU/hr. All the units, no matter are they using natural gas or propane, are having the energy factor 0.82 which qualifies them as the Energy Star appliances, eligible for government tax breaks.


General Electric water heaters with the tankless technology are available in two sizes only, 7.5 gpm and 9.4 gpm, both groups with an option for an indoor and outdoor installation. These are maximum flows calculated for the temperature rise of 35 F.

There are four tankless models with the 9.4 gpm water flow: indoor model GN94DNSRSA and the outdoor model GN94ENSRSA factory set for natural gas; indoor model GP94DNSRSA and outdoor unit GP94ENSRSA factory set on LP gas. All indoor models are using 5x3" concentric direct vent for venting products of combustion out, while outside mounted units do not require any vent option.

Tankless models with 7.5 gallons per minute hot water flow can be found as an indoor model GN75DNSRSA and outdoor model GP75ENSRSA, both units are factory set for natural gas.
