Gas Condensing Energy Star Water Heater
The very latest eco friendly gas water heater is the Gas Condensing Energy Star Water Heater, which will be in the stores by the middle of 2010. If you’re able to wait until then you can buy a gas water heater that will cut your heating expenses by 30% using the very latest technology. Gas condensing water heaters are very efficient and heat up the tank replacement water almost as soon as it fills.
An Energy Star water heater which uses the gas condensing method works in a similar way to normal gas water heaters, with a large insulated tank heated by a gas burner. The difference is that in place of venting the combustion gas outside, the gas is captured and used to heat up the water more.
A normal tank gas water heater works as if it were a water tank on top of a gas fireplace with the chimney going straight up the middle to an outside exit at the top. A gas condensing water heater has its flue designed with a higher surface area. The combustion gases have to travel much farther before they exit the water tank, so more heat is transferred to the tank water.
