HS25NG/LP, MH25NG/LP specifications

The Mr. Heater HS25NG/LP and MH25NG/LP are reliable and efficient heating solutions designed for both residential and commercial spaces. These powerful units deliver warmth and comfort, making them ideal for garages, workshops, and outdoor settings.

One of the standout features of the HS25NG and MH25NG is their versatility in fuel options. The HS25NG is designed to use natural gas, while the MH25NG operates on propane, providing flexibility based on user needs and availability. This adaptability allows users to select the most convenient and cost-effective energy source for their heating requirements.

Both models are equipped with a robust heat output, with the capability to deliver 25,000 BTUs per hour. This level of performance ensures quick heating even in larger spaces, establishing a comfortable environment in minimal time. The units also feature a wide heating area that can efficiently cover spaces up to 600 square feet, making them suited for various applications.

User safety and efficiency are paramount in the design of these heaters. The HS25NG and MH25NG come with an automatic shutoff system that activates if the unit tips over or detects any obstruction to airflow. Additionally, they are equipped with a built-in piezo ignition system, enabling easy and reliable lighting without the need for matches or an external ignition source.

The heaters also incorporate advanced technology to optimize performance. Their infrared heating design allows for direct and efficient warmth, minimizing energy loss and ensuring that heat is directed where it's needed most. This not only enhances efficiency but can also lead to reduced energy costs over time.

Both models are designed with portability in mind, featuring a lightweight construction and convenient carry handle, making it simple to move the unit from one location to another as needed. The durable construction ensures that they can withstand the rigors of frequent use, whether it be in a workshop or an outdoor gathering.
