Eternal water heater


Eternal’s GUI20 hybrid water heater provides homeowners with endless hot water for up to two applications simultaneously such as a shower and a dishwasher. The GU120 succeeds the previously available GU100 model and adds 20% more Btu. It contains Eternal’s patented heat exchanger technology and is up to 96% thermally efficient. The GU120 is ideal for residential retrofit and new construction projects due to its ease of installation, lightweight compact design, 1/2” gas line connection and convenient top-mounted water taps.
