Gas Fired Process Heaters
In many parts of the country, using natural gas instead of electricity can significantly reduce energy costs. Besides reducing costs, there are often programs that provide energy credits to companies who reduce energy usage - so there can be a double benefit in switching to gas.
The key to maximizing benefits is choosing a gas-fired process heater that has the highest energy-efficiency possible. Most gas-fired heaters have an efficiency rating of only 75-85% but there are models with 90+% efficiency ratings.
