The Environmental Protection Agency is working on new standards for wood stoves and heaters for 2015.
Wood heaters increase air pollution which has been linked to health problems, so they're hoping the new standards will make the next generation of stoves and heaters cleaner and safer.
Workers at Modern Gas say wood stoves had become more of a novelty item until a few years ago when gas prices rose.
"They are coming back into the market, we are definitely seeing an increase in sales in the wood stoves and people to look for alternate power source and of course a wood stove has very efficient heat," said Wendy Salter of Modern Gas.
The proposed standards would be phased in over five years to allow time for manufacturers to adapt.
