I would think the cost of heating, boiling water would exceed the cost of just buying distilled water, unless it just not available where you live.
It would all depend on how much each person pays for electricity or gas. Distilled/de-ionized water runs $1.00 to $2.00 per gal here in the US. Ads for electric home distilling machines claim to produce a gallon for $0.25. So boiling a gallon of water for 5 min should certainly cost far less than this. From a similar thread not so long ago some people in Europe pay exorbitant prices for distilled water if it is availale at all. .

A rock pile ceases to be a rock pile the moment a single man contemplates it, bearing within him the image of a cathedral.
