sounds like you did the same company move I did. although I did go up a few weekends befor my HHT as I am only a days drive away.. still looked at over 27 houses in 2.5 days then had to get a offer in so I could get everything else done in my 7 day trip.

on a side not although my home inspector didn't inspect the furnace and hot water heater, he did look at them, discern the age and modle ect.. and did recomend I get some one into look at them as they are at the normal life span age.. so although they can't inspect everything a good one will give you a good idea on the stuff he didn't fully inspect.. like it has been said there is only so much they can do in a 2-3 hour inspection, then after that the also spend anywhere from 1 to 3 hours with the buyer to explain everything. mine started at 8am and we got out of there at almost 2pm. as I had never had gas heating or hot water he did specnd a lot of time going over the workings and problems to watch for. ( I didn't have the hear to tell him I work on boilers the size of a two story house for a living as he was generly trying to be helpfull and make sure I was informed.) another thing to watch out for is a home inspector who will offer to fix things he finds, this is non partial and against the home inspectors board of BC rules.
