  • What is the difference between tank-less and traditional water heaters?

    As much as 30% of homeowners’ energy bills are used to heat water. A gas tank-less water heater warms water as it is needed rather than storing hot water. A tank-less system can be 20% more efficient than traditional water heaters. If you have an old water heater, you may find that replacing it with a more efficient model will also save you money on your utility bills. Blue Mountain staff can help you determine what type of water heater would be the best fit for your family. Learn more ›

  • What else can I do to save water?

    Blue Mountain can help detect leaky faucets in your house and fix them so you can conserve hundreds of gallons of water. According to the EPA, “a leaky faucet that drips at the rate of one drip per second can waste more than 3,000 gallons per year. That’s the amount of water needed to take more than 180 showers! Leaky faucets can be fixed by checking faucet washers and gaskets for wear and replacing them if necessary. If you are replacing a faucet, look for the WaterSense label. A showerhead leaking at 10 drips per minute wastes more than 500 gallons per year. That’s the amount of water it takes to wash 60 loads of dishes in your dishwasher.” Source:
