Smart Technology for Your Boiler

The Residential Fuel Economizer is the solution for single family home boilers.

The Fuel Economizer is a computer-based device that gets installed on your existing boiler improving its efficiency and allowing you to save fuel, save money and reduce your carbon footprint. It works with oil, propane, and natural gas burners.

The savings are normally between 12% and 18%. We guarantee savings to be at least 10% over a 12 month period commencing on the date of installation or we will remove the device and refund your money. In addition, the product is warranted for 15 years against manufacturer's defects. This 10/15 guarantee simply means you cannot lose. The cost is $695.00 which includes installation and sales tax.

The Fuel Economizer typically pays for itself in 2 years or less. Payback is governed by three variables:

  1. The price of fuel.
  2. The amount of fuel you currently burn.
  3. The performance yield of the unit.

Although the guarantee is 10%, typical fuel savings are higher. To see how changes in these three variables will impact you, please refer to our calculator.

Installation and programming typically takes less than an hour and is done by our licensed installers. Once installed there is no maintenance.

The Fuel Economizer is 4 inches square and attaches to your boiler's existing control which is known as an aquastat. Sensors are then attached at the boiler which provide the Fuel Economizer with the information necessary to calculate the current heating needs of the house.
