The ThermoMate 2.9 GPM is a propane-fired tankless water heater rated at 75,000 BTU, sized for one to two fixtures at once. It uses an oxygen-free copper heat exchanger and a flow sensor that adjusts burner output continuously to hold temperature within about ±1°F. It carries six safety protections, including boil-dry, overheat, freeze and flame-failure shutoffs. It suits small homes, cabins and single-bathroom setups; against larger gas tankless units it delivers less flow, so it cannot run a shower and a washer together in cold climates.

Owners rate it highly, with 4.8 out of 5 from 18 ratings. They report steady hot water for a single bathroom and easy wall mounting. A few note the flow limit when two fixtures run at once.
This is a 75,000 BTU propane tankless water heater for indoor residential use. It heats water on demand and delivers up to 2.9 gallons per minute, enough to serve 1 to 2 fixtures at the same time, such as a shower, sink or laundry. There is no warm-up time.
The heat exchanger is oxygen-free copper, which transfers heat well and resists corrosion. A water flow sensor and a built-in chip adjust the heating power 20,000 times per second. This keeps the water temperature within ±1℉.
The unit is 21 inches high, 13 inches wide and 7 inches deep. It fits in a small utility room or closet. Safety protections include boil-dry, overheat, water leak, anti-freeze, flame failure and high water pressure protection.
