We used Joe's Heating to install in-floor heating in a 4,200 square foot house. The reason I mention the square footage is that this was not a small job and Joe finished on time (one of the few contractors that was quick on the job) and on budget. We put in an Hydronic radiant floor system which pumps water from the boiler. We had the entire basement done as well as five bathrooms and the foyer entrance and these are all controlled through wall thermostats. What we liked about Joe the most is that we felt one of the zones wasn't working quite right and he came in four or five times with additional help to determine what the problem was at no additional cost. The system is now working perfectly and we strongly recommend Joe if you are looking to add in-floor heating to your new home (or existing home).
