How to deal with hard water problems?

There are many solutions to deal with this problem.

1.Most simple solution is to ignore the problem. Of course if you have to much money they are also a better ways to spend them than paying hire bills for hot water or for a new dishwasher.
2. If you decide not to ignore it you can do something with the effects of hard water problems. For example pour a little bit of vinegar into the kettle and boil the water to clean it from the limescale deposit. Also buy a sort of detergent to washing machines.
3.When you get tired of buying those useful but not working so efficiently 'gadgets' you can decide on having a special appliance which is more effecttive solution. It might be a water softener, that works by replacing the calcium and magnesium in the water with sodium.
4.Althought the above solution isn't totally worth of recommendation. Cause sodium in a high level isn't healthy, the appliance have to be refilled with salt, and it is relatively expensive. An alternative for that kind of device might be probably magnetic conditioner that treats water with a strong magnetic field. As a result, the chemical complexes, that could break down, remains in suspension and don't form crusts on the surface.
5.But again – this method has its weaker sides. To have benefits from it you have to install not only one device but few of them. And it is working only partially in good conditions like ideal flow of water. An alternative to all of those methods might be such device as Scalewatcher. It works similarly to other saltless water softeners but sends much stronger signal, remains water treated for a few days, reducing the amount of scale. Big improvement of this descaler  is that only one unit works for a whole house.

Of course it's your choice which solution to choose for hard water problems – something to deal with the problem once and for all or just useless half-measures, that will only cost you additional money.
