Gas heaters and fireplaces have been added to the Energy Star galaxy of appliances.

Energy Star appliances (which have the blue Energy Star mark) are the most energy-efficient available. Greater energy efficiency means lower running costs.

Energy Star gas heaters and fireplaces also have to meet stringent performance and safety testing and must be flued - so they don't release damp air or noxious gases into your home.

Gas heaters are great for fast, convenient and easily controlled heat. They're economical if you're already paying daily fixed charges for other gas appliances in your home.
