What it delivers

The ThermoMate CZ264LP 75,000 BTU Propane Tankless Water Heater is a propane tankless. Its listing gives a UEF of 0.81.

The listing doesn't state the BTU input, so its flow at your temperature rise can't be estimated from its own figures. The planner shows what your house needs.

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; material: 3.06 GPM; model: CZ264LP.

The listing gives dimensions of 13 in (W) x 21 in (H).
