What it delivers
The GASLAND E 199 199,000 BTU Natural Gas Tankless Water Heater is a non-condensing gas tankless with a 199,000 BTU/h burner and a stated maximum flow of 7.6 GPM. Its listing gives a UEF of 0.8.
Worked out from its input, it delivers roughly 6.8 GPM when the water only has to rise 45°F, and 4.4 GPM at a 70°F winter rise: 3 showers at 2 GPM in summer, 2 showers at 2 GPM in winter. Size it to your fixtures and climate.
Gas load at full fire: about 192 cubic feet of natural gas an hour. An older half-inch line that already feeds a furnace often can't spare that, so have a gas fitter check the pipe size and run.
Non-condensing indoor units run hot exhaust and vent in the maker's listed vent system (often stainless Category III), which costs more than plastic.
Other listed details: model: E 199.
The listing gives dimensions of 16.7 in (W) x 11.6 in (H).
