Benefits of Gas Heating
Energy efficient heating for a wide range of commercial applications
Direct/Indirect Fired Gas heaters
Various units can be coupled with either industrial evaporative coolers, energy recovery systems and ventilation units to provide effective heating and cooling in a neat roof mounted system, making them ideal for projects where energy efficiency is a premium.
This direct fired duct furnace technology uses a stainless steel burner and is supplied with electronic ignition and On/Off or modulating flame control, complete with all fittings to comply with relevant codes for the installation of gas fired appliances. These heaters can be used internally or externally.
Infrared Radiant Tube heating
Infrared heating is very effective at heating people without the need to heat the ambient air.
AIRA Radiant tube heaters vary in length and are installed at height above the area requiring heat. It can also be fixed at an angle, on a wall or suspended and can be flued or unflued. There is no naked flame, the black ray tubing heats and reflects heat towards objects.
They are available as single linear tube, double linear and U-tube in a range of lengths and with aluminium or stainless steel reflectors. Ball guards can also be provided for protection for use in sports halls or gymnasiums.
Flexible installation options make radiant tube heaters ideal for workshops, showrooms, supermarkets, gymnasiums, cafes and restaurants.

AIRAH gas heaters are hydrogen-ready for a renewable and sustainable future
The renewable gas future is here
Hydrogen, when used as a fuel, produces no carbon emissions and can be blended with or even replace the natural gas that is supplied to homes and businesses around Australia. Gas distributors are aiming to fully decarbonise their distribution networks by 2040 as a stretch target, with the Australian Gas Infrastructure Group aiming to deliver at least 10% renewable gas across its distribution networks by 2030 and 100% by no later than 2050.
Seeley International has been working with leading industry authorities to ensure that our gas heating products are “hydrogen-ready”, meaning they will perform at their best using hydrogen blends to provide the same warmth and comfort that thousands of Australian businesses expect and have been experiencing every winter with AIRAH gas heaters.
