Electric plenum heater
Use existing ductwork
 |
A plenum heater is a forced-air heating device that is installed in the plenum, which is the spot in the ductwork system where ducting and furnace join. Air is heated as it flows across electric elements and then distributed through the existing ductwork. A plenum heater is a low cost way to upgrade your heating system, to turn your fossil fuel furnace into a dual fuel system, and to benefit from off peak rates. Proper plenum space must be available in the heating equipment space. |
Plenum heaters can be installed while remodeling or during new construction.

- Meeting a home's total heating needs.
- Converting fossil-fuel systems to all-electric heating.

- Provides customer with choice of electric or fossil fuel operation.
- High safety factor.

How a plenum heater works with our electric service rates
You can operate a plenum heater on Otter Tail Power Company's general service rate or install it as part of a qualified off-peak heating system such as dual fuel or RDC to take advantage of rates that are about 3.3 cents per kilowatt-hour.
Note: If installed on an off-peak rate you may incur additional costs for a meter socket, and/or wiring.
Rates mentioned in web material subject to change On October 1, 2007, Otter Tail Power Company submitted a proposal to the Minnesota Public Utilities Commission (MPUC) to increase base rates for electric service in Minnesota for the first time since 1986. On November 27, 2007, the MPUC approved our request to increase rates by approximately 5.4 percent—over what customers paid in 2006, including the cost-of-energy adjustment—on an interim, or temporary, basis beginning November 30, 2007. The proposed interim rate increase will remain in effect until the MPUC decides the case in August 2008. Information reported on this web site does not reflect interim or final rate increases. We will update all rate information after the MPUC makes its final decision. |
