How could heating a bar magnet reduce its magnetism?
Is there a limit to magnetisation?
yes I have to either disagree and say no or you have answered regarding a given magnet or magnetised object. The earth is proof the answer is no, as it is encapsulated in a magnetic field, size of field is not limited - magnetisation or application of magnetic properties has no limits - magnetic fields of a magnetised object are limited, but not magnetisation or the capacity to magnetise.

How to Save Money on Central Heating Costs?
Due to the rising costs of oil, most people are struggling to deal with their rising heating and cooling prices. While central heating prices are much higher than they have been in the past, there are plenty of ways to reduce your central heating costs. One of the best ways to reduce your central heating costs would be to get a new furnace. Old furnaces tend to have much lower efficiency than a new one does. Because of this, if you switch to a new furnace, your furnace will need to work much less to keep your home warm. This will then reduce your central heating costs.
Is there a limit to magnetisation and why?
Yes, there is. To overly-simplify matters, magnetisation relies on the amount of coherently orientated unpaired electrons that exist in the material. This amount is obviously not infinite (because the material only has so many electrons, unpaired or otherwise) and so will hit a cap for the material in question. There are many types of magnetisation and all sorts of intricacies exist but this is a good way to look at it.

What are methods of magnetisation and of demagnetisation?
De-Magnetisation: Place in a field of alternating current; usually produced by a solenoid, and remove slowly out of the field. Magnetisation: Swipe with one end of a magnet until the iron/steel bar is magnetised. You can use many magnets if you want to speed up the process. The strongest magnets are created by wrapping coils around the bars, and inducing alternating current in these wires using a power source.
