Dual Fuel Plenum Heaters & Off-Peak Heating MN
Cut Your Heating Bill in Half
Stop paying full price for heat. By adding a dual fuel plenum heater to your existing gas or propane furnace, you qualify for the utility's Off-Peak rate—cutting your heating bill by up to 50%.
Propane prices spike when you need heat the most. Off-Peak electricity rates are fixed, stable, and significantly cheaper. By using electricity for 80% of your heating, you insulate your budget from market volatility.
How Dual Fuel Works
It's the best of both worlds. You get the low cost of electricity with the backup security of gas.
Plenum Heater
We slide a coil of electric heating elements directly into the "plenum" (air chamber) above your existing gas furnace. No need to replace your current furnace; it just becomes the backup.
Smart Switching
An outdoor sensor tells the system when to switch. Above a set temp (e.g., 5°F), you run on cheap electric. Below that, or during load control events, it automatically fires your gas backup.
Rebates & ROI
Most local co-ops offer huge rebates (often $400-$600) for installing off-peak heat. The system often pays for itself in just 2-3 winters from fuel savings alone.
Heating Cost Comparison
Standard Propane
- Rate: Volatile. Spikes when you need it most.
- Comfort: Blast of hot air, then cold drafts.
- Backup: None. Run out of gas, you freeze.
Dual Fuel Electric
- Rate: Fixed Low Rate (Off-Peak). 50% cheaper.
- Comfort: Even Heat. Modulating elements.
- Backup: Redundant. Gas takes over if electric stops.
Seamless Integration
We handle the entire switchover process. From the plenum heater to the utility receiver, we make the system work as one.
- Retrofit Ready: Our plenum heaters slide directly into your existing gas furnace ductwork.
- Auto-Switch: The moment the utility cuts power, your gas backup fires instantly.
- Utility Rebates: We handle the rebate paperwork to ensure you get your check.
