No
That depends on how well insulated the house is, and on what the external temperature actually is. -- Raising the thermostat some number of degrees will raise the fuel cost more with poor insulation than it will with good insulation. -- Raising the thermostat some number of degrees will raise the fuel cost more if the external temperature is -10° than it will if the external temperature is zero.
raising the thermostat on the water heater
By raising or lowering the temperature.

Yes.
Does is a liquid at room temperature, raising the temperature will certainly not turn it into a solid. Think about water. Raising the temperature of water will evaporate it and make it a gas. The only way to increase the temperature of something to make it into a solid is to also greatly increase the pressure.
If you raise a solution temperature the molarity will decrease.
Raising the temperature the density is lowered.
Decreasing the pressure -APEX
By reducing the pressure
"To save energy you can use a clothesline, unplug unused items, install compact flourescent or LED light bulbs, walk instead of driving, or turn down the temperature of your hot water heater. Buying a programmabel thermostat and dropping the heat or raising the cold temperature will also save energy."
Raising solvent temperature causes solvent-solute collisions to become more frequent and more energetic.
