My mother in law has a house in a foreign country and is looking for a in expensive way to heat a concrete block house (Total house including roof is concrete)

Concrete Block and concrete are great insulators. Once you have achieved the desired temperature, you should enjoy the temperature. During the heat, the inside will be slow to heat up, during the cold it will be slow to cool down.
Cheers and good luck!

To my way of thinking is you need to inner wall with R19 or better fibre glass and do a drop ceilling wtih R19 above. Then fibre board after a small airspace. Then central forced air.
An alternative could be small radiators placed around the room every 8 or 10 feet all the way around and hot water radiator furnace from a central control.
Once you get the heat up (a slow process) it will keep nicely.
It will help heat those walls from floor to ceilling as heat rises and the radiators are floor height to 3 or 4' off the ground.
a 360 radiator system can be quite efficent and cost effective over a forced air system without adding insulation.

Hints:
What are the energy sources and their costs?
How does the average O.A.T. vary?
Concrete has a lot of thermal mass, and so holds
temperature well, but it's not too good an insulator.
