Does hard water heat easier than soft water ? Will I burn more oil to make domestic hot water ?

I have hard water lots of calcium and minerals.I want to install a Sears water softener,will I burn more oil to make the same amount of domestic hot water? I do know we will take shorter showers if I get it and use less soaps. I need a science EGGHEAD to help me out. Any 9 grade teachers out there?Does hard water heat easier than soft water ? Will I burn more oil to make domestic hot water ?
Softened water just trades sodium or calcium chlorides for other ions in your hard water(like iron). I would expect your boiling point of this softened water to remain relativelly the same or close enough that you won't see a difference on your stovetop.





However, you will probably use more water and take longer showers as with the softened water can be difficult to wash the suds off.Does hard water heat easier than soft water ? Will I burn more oil to make domestic hot water ?
Yes, it will take more energy to heat it. It is called a colligative property. Any time you dissolve a substance in water, you extend the liquid phase of water...meaning it stays a liquid at higher and lower temperatures where pure water would have begun boiling or freezing. This is why you put salt on the sidewalks in winter and salt in a pot of water to cook pasta (it cooks the food faster because the water has more energy when it does reach its boiling point)
