  3. Always maintain two feet of clearance around the water heater unless the manufacturer specifies otherwise.
  4. If you have an older water heater, you may want to consider adding a layer of insulation around it to help it hold heat and use less energy.
  5. Don’t forget to adjust the water heater to the lowest setting if you plan to be out of town. Some heaters have a built in “vacation” settings that you can easily switch on and off.
  6. If you feel that you aren’t getting your full tank of hot water that could be because you tank is filled with sediment.

Reverse Osmosis Systems

Offer pure drinking water for pennies a gallon. Reverse Osmosis filtration is the easiest and most inexpensive way to significantly reduce unwanted mineral and chemical content from your family’s drinking water. This process changes the properties of your water so significantly that it makes your water super pure and taste great. Removes lead, chlorine, and reduces other contaminates up to 99%. Most bottled water is purified through reverse osmosis, but producing bottled water wastes more water than a reverse osmosis system. Think about all the water required to make one bottle of water. When bottled water is purified, wastewater is sent to the drain, and producing the bottle uses water and petroleum. Petroleum is used again to deliver the bottled water to the store. A reverse osmosis system provides water just as pure as bottled water without as great of a cost to the environment.
