It takes my gas furnace about two hours to get the house up to the setpoint of 72F when it's been off for a long period of time. How much will it cost to run a 2kW electric heater along with the gas furnace.

What about the money I save on gas by giving part of the load to the electrical heater? I think I might actually save money.

Electric heat will always cost you more than gas heat.
1 Kilowatt-Hour of electricity costs me $0.0852 (from my electric bill)
1 Kilowatt-hour = 3412 BTU
1 Therm = 100,000 BTU, and costs me $1.086 (from my gas bill)
(3412/100,000)*$1.086 = $0.03705
so 3412 BTU costs $0.03705
So it would cost me $0.0852/$0.03705 = 2.3 times as much to heat my house using electricity.

At today's rates, natural gas is significantly cheaper than electricity for providing heat. For your situation, it will depend on what you have the house set. I would estimate that if the space heater is running constantly, then you're loosing the cost benefits from natural gas. Where a space heater is really useful, is for "spot", (close to what you're doing). I have a small heater on a timer that comes on to heat the bathroom. I do this instead of heating the whole house in the morning. So that the heater runs for about 15-20', which previously the furnace ran heating the whole house.

Depends hugely on the electricity tarrif you have - and if you have some form of economy 7 / dicsount for night heating.
If you pay 12p / 24c for kWH, then it will cost you 24p / 48c for each hour that it is running.
To keep it on for the full two hours would cost you 48p / 96c
( cost per KWH * 2(kw) * 2(hours) )

If it runs for 2 hours it'll use 4 kwH. How much does your utility company get for 4 kwH?

if 1kwh= $.10
then $.20 an hour for the electric heater.
make cold rooms and hot rooms
if you aren't using a room seal it off.
sometimes separate rooms with a curtain.
seal windows well, they have plastic kits that go over the whole window.
