Assuming you have an inspection contingency in your contract, did your attorney revise the inspection terms during attorney review? Most attorneys will allow a dollar amount for inspection issues that either buyer or seller can walk away if results of the home inspection are above and beyond a certain dollar amount.
However in the case of older appliances, furnace, etc....was there a Sellers Disclosure? If so, did it state the age of the water heater, furnace, etc. and in what working condition they were in? Not being a licensed inspector, could you tell from just looking at the heating system, boiler, etc. that they were old/outdated? If so, then pretty much you were aware of how old they were thus making your offer should have reflected that and it is kind of moot point to bring it up now but you still can should you choose to and if your inspection contingency/terms apply.
Now if there was no seller's disclosure but your inspection report revealed that they are older but in working order - then you can try to negotiate if a seller will pay for a home warranty (be sure to read the terms of the warranty so you completely understand what is covered and what is not). If the seller will not pay for a home warranty, you are by all means allowed to take your own policy out but again be sure of its terms. In the alternative, you may seek a credit for a reasonable dollar amount.
You should definitely be speaking about the inspection results with your attorney and your agent because they obviously know the inspection contingency/terms relating to your contract. Again, depending on your terms and to answer your question -- typically a home warranty and/or credit takes care of those types of issues arising out of a home inspection.
Good luck and call your agent and attorney.
