What it delivers
The GASLAND CE686NG 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.
Expect about 4.4 GPM with cold winter water (a 70°F rise) and 6.8 GPM when the inlet is milder (45°F rise); that is 2 showers at 2 GPM in January. Check it against your own fixtures.
At full fire it burns about 192 cubic feet of natural gas an hour. The gas line has to carry that on top of the furnace, range and dryer; a gas fitter sizes the pipe from its length and the total load.
Its exhaust runs hot, so the vent must be the material its manual lists, usually stainless; budget for the vent kit.
Listed details: material: Iron, copper; model: CE686NG.
The listing gives dimensions of 14.25 in (W) x 24.69 in (H) and a weight of 37.5 lb.
