When looking for a vented heater for an ice fishing house, consider the heater design, the type of fuel it uses, the size of the ice fishing house, and the amount of time the heater needs to function. Ice fishing huts are heated by either radiant or convection heaters. Radiant heaters give off heat to the area around the heater, while convection heaters use a heating element or the air circulating around the hut to heat the entire room.
Portable infared heaters use propane. They are small and can safely and efficiently heat ice fishing huts up to 200 square feet. Larger propane heaters can warm rooms up to 400 square feet. Propane heaters run off of propane canisters and, depending on the canister size, can last up to 200 hours. Many models also have the option of running off of a D-cell battery for a limited time; others can run off of a 110-volt outlet.
A wall-mounted, gas-powered heater can heat up to 300 square feet. Some models include oxygen sensors that signal a warning when the oxygen level inside the ice fishing hut is too low.
Indoor heaters must be safe for use in a small space. Some require an outside vent.
