Calculations of Cost of Heliosa short wave infrared verses Gas Heaters

The heat
projection of gas ceramic heaters makes them popular outdoor undercover heaters
for use in hospitality and other large open areas such as factories and
warehouses.

To achieve the
radiant heat ‘throw’ they need a good supply of gas and are generally in the
range of 25 – 40 Mj per hour capacity.
Often requiring deflectors to reduce loss of heat to the area above the
heater, it is not uncommon on a cold day to see waves of heated air floating
away from the people it is intended for.
This is because the radiant efficiency of the medium wave infrared is
around 60%.

This same issue
affects the standard patio heater fueled by 9kg LPG bottles. The ‘mushroom’
deflector is designed to direct the heat downwards, but instead tends to
dissipate heat to the immediate surrounds. At best, these heaters have a
radiant efficiency of 40%. And while they may claim to heat large areas, they
are only effective for a very limited radius.

We have
recently completed cost comparisons between our new Heliosa short-wave infrared
heaters, and gas heater alternatives. Short wave heaters offer instant heat at
92% radiant efficiency – resulting in less energy loss to the atmosphere.
Unlike most other commercial electric heaters on the market, they can cover
similar square meterage as current gas alternatives.

Purchase costs
for Heliosa infrared heaters are a fraction of wall or ceiling mounted natural
gas ceramic heaters. They also are less costly to install and running costs are
comparable, yet efficiency is so much better. Once installed, Heliosa heaters
are significantly cheaper to run than patio heaters with a payback period of
just over one year.
