I am looking to buy a home and now realize that I don't know ANYTHING when it comes to heat systems. A home I looked at recently be very nice but used radiators, I am wondering if a home resembling this could be converted to use a thermostat.
Answers:    Houses that have radiators are in actuality run off a thermostat but respectively radiator also has shutoff valve on both ends if you want to shut off or adjust one single radiator. If the thermostat isn't working next it is very undemanding for someone to replace it either themselves (I did mine myself, it be like $30 at home depot) or own a HVAC company do it.

As background: There are hot dampen and steam radiators depending on whether hot water or steam is running surrounded by the radiators. The boilers that heat the steam/water can be any electric, natural gas or grease. All the houses I have be in that use radiators are remarkably comfortably warm surrounded by the winter and the systems work very economically. Also, even in the comatose of winter the radiators do not get hot satisfactory to actually burn someone. The chief fault that race have beside radiators is that they are kind of unsightly. If you build covers around them later air can't circulate as very well and the radiator is far less streamlined. During your home inspection you need to turn on the entire system and hang about a few minutes to make sure that adjectives the radiators in respectively room get reheat. Also, my grandfather's house was 90 years hoary when he passed and in the 60 years that he lived in attendance the radiators never leaked.

If by "convert to thermostat" you parsimonious rip out the radiator system and replace it with intermediate air/heat by running air ducts to adjectives the rooms then it would cost over $10K and thieve a couple weeks.
More than likely the boiler warmness system still utilizes a thermostat which is nothing more than a messenger. The thermostat sends a message to the boiler describing it to cut on or cut off. There are some radiators that hold their own thermostat around the shut off tap to control the messages that go to that specific radiator as opposed to adjectives the radiators.
If by converting you mean shifting from boiler heating system to a gas or electric forced nouns the price depends on many things, sq. footage of the home, foundation type (slab, crawlspace or basement) and how would the duct work be run. I will speak it is very expensive to modify heating types and possibly a operation breaker if you don't like boiler heat.
