Unhappy i need some directions

hi guys, this is my first post, i am currently doing a task involving heating, the task requires analysis of heating method, disadvantages and advantages as well as benefits, all the while relating it to physics. i am quite puzzled as to how i will approach the topics of natural gas heating and Air conditioning heaters, i feel like talking about pollution and just dong a chemistry presentation, however, my task requires me to do loads of physics, so does anymore have any suggestions?

Well I will take you at your word that you know enough Chemistry to prepare a presentation on heating systems, advantages and disadvantages, in that subject.

Have you no thoughts on the Physics of the situation?

First you need to determine - "advantages and disadvantages" - To whom?

The person or building being heated or the environment at large?

Now all forms of heating require fuel.

I see you are in Australia where folks can be pretty isolated.
So have you considered the cost and practicalities of getting that fuel to its point of use?

What about the safety aspects of servicing the heating equipment.
How paractical (+ cheap) is it for a service engineer to travel 800 miles into the outback once a year to service one single gas heater?

I would think Australia provides the idea stage to examine and compare the the settings of providing and maintaining heating systems in large communities and isolated ones.

One aspect that could allow you to include additional "physics" might be the end-to-end efficiencies of various methods.

Electrical heating requires generating, transmitting, converting to heat...
each with their inherent inefficiencies.
Gas requires extraction, pumping, converting to heat,
and generates pollutants

Electricity is often generated in gas powered generators, so is not the completely "clean" power source it is sometime portrayed as.

Combined heat and power systems were the great new thing some years ago, but seem to have gone quiet recently.

I'm glad the ideas were of some use.

If you were able to widen your horizons a bit you could include more modern approaches in your considerations.

Gas boilers can now be obtained that use the waste heat to generate electricity.

Electricity itself can be used more efficiently than direct heating, by way of a heat pump.

This technology could be particularly attractive in Australia since the process can be reversed and also provide cooling.

What both of you said was very helpful, I have since then made more adjustments to my planning, thank you for your constructive suggestions and ideas.
