A Water Heater Blanket Could Save You Money
With the frigid temperatures right now, it might be a good time to investigate whether or not you could use a hot water heater blanket. If your water heater is in the garage, there's a good chance it's having to work harder these days to keep the water hot. The way to find out if you could use an insulation blanket is to hold your hand on the outside of the heater. If it feels warm, you can use a blanket. Some newer models don't need them and will have a warning on the heater advising against using the blanket.
The blankets are fairly inexpensive and easy to install on the electric water heaters. You can find them at a cost of around $20.00 at Lowes, Home Deport, or just price shop on the internet. Amazon even sells them, but you'd have to pay for shipping so there isn't any real savings.
In case your water heater is gas, here's a link that you should visit since the installation is more complicated since you have to make sure you don't obstruct the airflow to the burner. http://www.energysavers.gov/your_home/water_heating/index.cfm/mytopic=13070
