What it delivers
The forimo CT1412-HWRSQ Propane Tankless Water Heater is a propane tankless with a 81,888 BTU/h burner.
At a 45°F rise (mild inlet water to a 120°F set point) it holds about 2.8 GPM, 1 shower at 2 GPM; in winter, at a 70°F rise, about 1.8 GPM, less than one 2 GPM shower. Size it to your fixtures and climate.
Gas load at full fire: about 0.9 gallons of propane 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.
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: 1/2" npt; material: Copper, Stainless Steel; model: CT1412-HWRSQ.
The listing gives dimensions of 13.8 in (W) x 21.7 in (H) and a weight of 21.9 lb.
