by heating we increase the inter moleculer space of the solvent so the solute particles get in the increased space and by stirring also the same purpoose is served . in short it is done so as to dissolve the solute in the solvent
Heating will help solutes dissolve in many solvents. For example salt will dissolve in hot water better than cold water.
Many chemical reactions either require energy input to initiate a reaction, or they react better at higher energy levels.
Endothermic reactions require energy to proceed.
Even exothermic reactions may require activation energy to initiate the reactions.
Or... many reactions won't run efficiently or completely at cold temperatures.

Why do some hot water heaters need thermal expansion tanks and others do not?
I believe that the larger the hot water tank, the greater is the need for an expansion tank. Water expands as it is heated. This is why all hydronic heating systems require an expansion tank. A water heater would need expansion tank when a backflow preventer or check valve is installed in domestic cold water line directly after water meter. Some areas require backflow prevention, but not all. Have to check with local plumbing authority about that.

How does a hot water heating system works?
Hot water heating systems use a boiler to heat water and a circulator pump moves the heated water through some kind of radiation. A thermostat controls the on off function and keeps the area at a set temperature. If you need more I have ebooks on the subject. You can find them by searching "Robert VanNorden" on Amazon.com. or search"hot water heating systems" on Google and my book "Understanding Hot Water Heating Systems" will come up on page 1.
