Surgery - Colorectal. In brief: Yes, most docs can. Most hemorrhoids should first be treated by conservative measures, such as bulking the stools, education to avoid bad habits like straining, sitting for long periods of time, etc.
Either system will have a burner. 23 years may very well be beyond the typical life expectancy of a oil burner, but a furnace or boiler should last considerably longer than 23 years. The boiler of my house here in MA is 58 years old and still works fine. I am starting to consider replacements, however.
How long does a home furnace last? I have a Carrier furnace that was installed in 1995, and the other day the fan unit died, to the tune of $685. I'm guessing that the furnace may not last much longer, but I wondered what wisdom others may have about this kind of thing. Can I get 20 years out of it, or should I start saving for... It should last another 20 years but its probably still going to need repairs within that time.
