  • Calcana Authorized Dealer

    Calcana Standard Output Stainless Steel Gas Patio Heater is a long, sleek, and sophisticated indoor or outdoor heater. Powered by propane or natural gas, this infrared heater can work at high altitude and is not affected by the wind. Available in sizes: 10', 15', and 20' long.

    This commercial-grade stainless steel heater has a modulating control panel so you can set the heat just right for maximum comfort. The heating area varies according to the heater's length. The 11.5, 16.5, and 21.5 ft models can heat an area up to 104, 180, and 312 sq ft respectively. Optimal conditions such as the ideal mounting height and mild climate are needed to heat the maximum space. Best installed overhead or wall-mounted at an angle - anywhere outdoors or indoors with special venting.

    Heat output is the hottest at the burner head and diminishes down to the exhaust. Ideally installed in pairs with the heaters parallel to each other, separated by 8' to 14′, and with their opposite ends facing each other (burner-exhaust) for even heating.

    If you are looking for an extremely powerful heater for your home, commercial, or industrial space and the length is not a problem, a Calcana Standard Output heater is an excellent choice.

    High Output outdoor heaters are also available in sizes: 5' and 10' long. High Output heaters pack the same power as Standard Output heaters at half the length, are better for spot heating, and are available in marine grade stainless steel.

    This heater is great for residential and light commercial applications. Multiple units can be grouped together to achieve any length required.

    As a general rule, it is suggested to locate the burner end toward the highest heat-loss area (doors) of the space being heated because heat output is the hottest at the burner head and diminishes down to the exhaust. Mounting height of 8' in cold climate areas is recommended. In areas with milder climate, 9' mounting height is acceptable.

        Best Patio Heater ever

        We have been looking for a strong powerful heater for our patio that is not affected by weather and this heater fits the bill. We now had this heater for a number of years and the stainless steel body doesn't show any sign of corrosion. We can only recommend this great heater.

        Radiant heat heats everything nice without blowing everything off dinner tables...

        It has increased our capacity for sitting...and it is something that we're gonna be able to use all year around. It has definitely caused a lot of increased business and definitely improved our ability to serve our customers. Radiant heat heats everything nice without blowing everything off dinner tables... We have a dial so we can dial it in on all the units based upon our sections. So if we are only using the back area we can only dial that back area... It is a huge benefit for us to be able to kind of control each individual climate. I would absolutely recommend looking into getting these heaters on your establishment.
