APUS AP-AWH-Q13LPG 95,000 BTU Propane Tankless Water Heater

What it delivers

The APUS AP-AWH-Q13LPG 95,000 BTU Propane Tankless Water Heater is a propane tankless with a 95,000 BTU/h burner and a stated maximum flow of 4.4 GPM. Its listing gives a UEF of 0.81.

Expect about 2.1 GPM with cold winter water (a 70°F rise) and 3.3 GPM when the inlet is milder (45°F rise); that is 1 shower at 2 GPM in January. Run your house through the planner.

The line must deliver about 1.0 gallons of propane an hour when it fires flat out. The requirement calculator adds it up; a licensed fitter confirms the pipe.

Its exhaust runs hot, so the vent must be the material its manual lists, usually stainless; budget for the vent kit.

Listed details: material: 4.42 GPM 95,000BTU; model: AP-AWH-Q13LPG; warranty: 2 Year Manufacturer Warranty.

The listing gives dimensions of 5.9 in (W) x 20.55 in (H) and a weight of 19.2 lb.

Warranty, per the listing: 2 Year Manufacturer Warranty.

Questions buyers ask

How many showers can the APUS AP-AWH-Q13LPG 95,000 BTU Propane Tankless Water Heater run at once?

From its 95,000 BTU/h input we estimate about 3.3 GPM at a 45°F rise and 2.1 GPM at a 70°F rise, so 1 two-GPM shower with mild inlet water and 1 in a cold winter. The maker's flow chart for this model is the final word.

What size gas line does the APUS AP-AWH-Q13LPG 95,000 BTU Propane Tankless Water Heater need?

At full fire it uses about 92 cubic feet of natural gas an hour or 1.0 gallons of propane. The pipe size depends on the length of the run and every other gas appliance on it; the maker's manual and a licensed gas fitter decide it.
