A Dual Fuel system can heat
your whole building using electricity and another
fuel. You enjoy the benefits of a lower rate by
agreeing to switch to back-up (or dual) fuel during
peak times. In fact, you can save up to 50 percent
off regular electric heating costs. We even provide
the metering equipment for free.
How it works
Your electric heat is
interrupted during peak demand times. An alternate
non-electric or electric thermal storage (ETS)
heating system then heats your home during these
peak times, generally on the coldest days of the
year.
Interruptions can occur at any time for any length
of time, up to 12 consecutive hours. The total
amount of cumulative hours cannot exceed 400 hours
per heating season.
Your satisfaction with this program depends on the
ability of your back-up system to keep you
comfortable during extended interruptions.
What are the requirements?
The secondary (or back-up)
heating system must be automatic and adequately heat
your building for as many as 400 hours. To qualify
for the rate, all the electric heat in your home,
except bathroom heaters, must be controlled.
Portable heaters and wood-burning systems do not
qualify as a secondary system. Electric thermal
storage does qualify for back-up on all Dual Fuel
systems.
Dual Fuel Options
For New Construction
Install electric baseboard heating with an automatic
back-up system such as gas, oil furnace or ETS.
For Existing Buildings
If you have forced-air electric heating, install an
automatic back-up system such as an ETS, oil
furnace, etc.
If you have forced-air, oil or propane heat, install
an electric plenum heater that is inserted into the
hot air plenum of the existing heating system.
Electric baseboard or heat pumps can also be added,
leaving a fuel system for back-up.
If you have electric baseboard, ceiling cables or
panels, you can add:
- ETS room units for
automatic back-up
- Ductwork and a
forced-air back-up furnace
- A wall-mounted gas
furnace that vents through a side wall
If you have a boiler, install an electric boiler
conversion unit.
