If you bought a water heater this year — or think yours should be replaced soon — this post could be worth $300 to you.

KSTP reported last night that taxpayers have until the end of 2011 to buy energy efficient products to qualify for incentives, such as a $300 water heater tax credit. See the website for full details on what qualifies and the maximum amounts you can receive.

Also if you for replace your water heater with an energy efficient model, local utility companies such as Xcel and Centerpoint both offer water heater rebates (about $40-$200) , which you can find on the Database of State Incentives for Renewables & Efficiency.
