This is a question everyone should ask, and every heating technician should be able to answer.
If the whole house is heated with only one type of fuel, then doing an accurate heat loss analysis of the structure, and then applying that heat loss value to the severity of the heating season (measured in degree days) will be a good predictor of how much energy will be used to heat the home.
If you heat with electricity, you will get 3,413 BTU's for every KWH of electricity you use for heating. If you heat with #2 fuel oil, you receive approximately 140,000 BTU’s in every gallon of fuel oil you purchase. For propane, it has approximately 92,500 BTU’s of energy for every gallon, and natural gas has approximately 100,000 BTU’ for each CCF of gas consumed. In all cases, multiplying the above values by the seasonal efficiency rating of the heating system will yield the usable energy from every unit of fuel consumed. Now, divide that number into the energy your structure will loose over the heating season, and you will have the number of fuel units needed to heat the structure. Multiply the required number of fuel units by the cost per fuel unit and that should give you the approximate cost of fuel for a heating season (whew ... math 101).
As for the type of heating system, in floor radiant tends to be a little more efficient than other systems as the room air can typically be kept a little bit cooler, and yet the same comfort level will be felt, and that's because of the characteristics of in floor radiant heat.

One you know the current / power figures for your heating installation, do the calculation as follows.
If only current is stated, multiply the amps x 240 to get power in watts.
Now, assuming a rating of: 1000 watts or 1kW
1kW for 1 hour = 1kWh (1 unit)
Look at your last bill for the cost per unit (during the period you have it switched on) and multiply by your power rating above to get your hourly cost.
e.g. 1unit x 13.94 = 13.94pence per hour
I hope this helps

Did someone just say something about carts before horses. I'll bet you are one of these who has to touch paint when they see a sign saying its wet!
If you find the system is too expensive, will you leave it switched off? Your a bit late in the daty with your query

Hope you've not fitted on top of a concrete floor? If you have you will simply heat the concrete and not the room-very expensive don't use.
you should lay insulating board or plywood under it,otherwise your wasting you time....think on

You need to state the size of the mat and the load/sq/m before it can be calculated! Wer'e not mind readers on YA
