It offers two power settings (1000W and 1500W), allowing some control over heating intensity. This model stands out for its built-in digital thermostat and temperature sensor probe, making it easy to set and maintain your desired temperature from 30°F up to 120°F. The heater is water-resistant (IPX5 rating), so it can be used safely in damp environments like greenhouses or garages.

It runs on 240 volts and requires a heavy-duty 55-amp circuit, so professional installation with hardwiring is necessary, which might not be convenient for all users. The heater features a sturdy steel frame and safety guards on both the intake and output ends, adding extra protection against accidental contact with hot parts. It includes an adjustable thermostat that lets you set temperatures between 37°F and 104°F, helping maintain a comfortable environment without wasting energy.
