Replacement Gas Unit Heater

Installing new efficient gas unit heaters can improve comfort in your building and save money during the winter months.

Consideration should be given to replacing your existing unit heaters in any of the following situations:

Significant Energy Improvements Have Been Made

Significant energy improvements such as new windows and additional insulation can reduce heating capacity requirements. Depending on the age of the existing unit it's possible that it is oversized. Units that are oversized operate inefficiently. New efficient units sized for lower heating requirements could save you money.

The Building Will Be Expanded

A building expansion will likely require additional heating capacity. Depending on the layout of the building, you can either add additional heating units to the new space, or remove the existing units and install larger heating units throughout the space. Any new units added should be high efficiency units.

Savings are based on a 136,000 BTU output high efficiency gas unit which costs $3,366.00* per year to operate.

Your Existing Gas Units Are Old

Replace older gas unit heaters with new units. The new units will operate more efficiently and provide better comfort at a lower cost. Efficient unit heaters are available with electronic spark ignition and power venting. An electronic spark ignition replaces the standard pilot light and ignites the gas burner only when necessary. Standard unit heaters are gravity vented, having a vertical flue to vent the products of combustion. These units are inefficient since room air is drawn out the vent. A power vented unit heater uses a motor to pull combustion air through the unit and as a result, maintains an optimum fuel air ratio for more efficient combustion. A vertical flue is no longer required, thus reducing wind effect and gravity stack losses. High efficiency unit heaters can be as much as 25% more efficient.
