What it delivers
The Heatrova TGHT001 102,000 BTU Propane Tankless Water Heater is a propane tankless with a 102,000 BTU/h burner and a stated maximum flow of 4.3 GPM.
At a 45°F rise (mild inlet water to a 120°F set point) it holds about 3.5 GPM, 1 shower at 2 GPM; in winter, at a 70°F rise, about 2.2 GPM, 1 shower at 2 GPM. Check it against your own fixtures.
At full fire it burns about 1.1 gallons of propane 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.
From the listing: connections: 3/4" npt; connectivity: leak detection; model: TGHT001.
The listing gives dimensions of 13.7 in (W) x 13.7 in (H).
