Combination systems can also be adapted to new hydronic baseboard installations. Because gas cooling does not rely on electric motors to run a compressor, the equipment generally lasts longer and requires less maintenance and fewer repairs than does comparable electric equipment. In general, recovery times for gas units are considerably shorter than those for electric units, providing more hot water in less time for both residential and commercial use. And gas water heaters last longer because the continual circulation of water eliminates sediment buildup that can cause operating problems in electric models. They are also highly reliable and long-lasting.
Clothes dryers cost less to operate than do comparable electric models.
Grills fueled with natural gas have a number of advantages over charcoal grills, including far more efficient cooking with virtually no clean-up. Like gas fireplaces, they are also environmentally friendly when compared with charcoal alternatives. Special-purpose heaters for pools, saunas, patios, garages, and hot tubs can maximize the use of those spaces by warming their water or air temperatures during cooler months. Snow melters can contribute to safety and convenience for residential and commercial buildings in snowy climates. And they get rid of snow without the use of gasoline-powered snow blowers and plows, which can contribute to air pollution.
