These products are not subject to the “Ordinance on Safety of Boilers and Pressure Vessels” of the Industrial Safety and Health Act, Japan.
The GTLH model realizes thermal efficiency of 105% through the recovery of latent heat
(the thermal efficiency of the GTL models is 95%)
The latent heat recovery device is design to let an exhaust gas flow inside the device appropriately so that the gas can
efficiently be removed into the drain water, realizing a high thermal efficiency.
Exceptionally high efficiency through the proportional control combustion system
The burner does not need to be stopped until the load reaches 20% of the rated load, which suppresses reduction of the
efficiency due to repetition of start and stop.
Space saving design, and piecemeal delivery is possible
The main unit and latent heat recovery device of the vacuum type gas-fired water heater can separately be delivered, which
enables easy installation even in a place with a narrow carry-in path.
