Gas to electric conversion rebates: Some residential members may be interested in converting gas water heaters and furnaces to electric due to rising costs of natural gas and propane. GreyStone has two rebates available for members who convert from gas to electric.

  • If the requirements are met, the member becomes eligible for either a $400 or $200 rebate after converting a water heater from gas to electric.
  • By meeting the requirements, members become eligible for either a $600 (Energy Star Rated) or $300 (Non Energy Star Rated) rebate when changing from gas heat to an electric heat pump or dual fuel.

Propane Water Heater Replaced with Electric

  • Rebate of $500 for water heater with 12 year or better limited warranty
  • Rebate of $300 for water heater with less than 12 -year limited warranty
  • Rebate of $500 for Marathon or Heat Pump water heater

Energy Saving Tips

Summer cooling and winter heating, followed by water heating, are the major users of energy in your home. These few items will usually have the biggest impact on your energy bill.

Every degree below 78 in the summer increases your bill 3 to 5 percent. Don’t set the thermostat any higher than 2 – 3 degrees when leaving as it take more energy to bring your temperature down on hot days than to keep it consistent. Also, when you leave for vacation, keep the temp around 82 degrees for maximum savings.

Our savings guide will show you how to make the most of the energy you consume each day. It is broken down into the following sections:



  • Insulation and air tightness
  • Heating and cooling system

  • Electric water heater operating cost
  • Pool/Hot Tub operating costs
  • Electrical costs of household items and how to save energy when using them
  • Lighting and appliance energy-saving tips
