ok so this may seem like a ridiculous question... but basically im looking for a way of getting my water to the right temp before doing water changes, i dont want to use warm water out of the tap as it comes out cloudy sometimes, so would using a kettle and boiling water then mixing this with coldwater before adding to the tank be ok? or will the fact that the water has been boiled affect anything?
The cloudiness will go away within a few hours. I wouldn't worry about that. Some people use athermometer to get the water extemely precise. All I do is with my last bucket I empty from the tank, I pour tank water in a glass to the top and as I fill the bucket with fresh tap water I put one finger from one hand in the glass and a finger from the other hand in the bucket and match the temperature as close as possible, adjusting the faucet as I need to. I'm usually within a degree or so and with only changing 30%ish of the water, being within 1 or 2 degrees of the tank water will not harm the fish. When mixing with the rest of the tank water, it will be less than a degree difference for the fish.
In calcareous water that is NORMAL and it'll dissolve within your bucket when adding water conditioner within minutes. Just adjust the temp of the water by hand test make it more less same then the tank is, let sit for few mins and then add it to your tank.
What you're describing there, you have a very good water with plenty minerals; boiling your water before using it you'd boil all the good stuff out so to speak and that's not beneficial for your tank.
