A data logger with four or five sensors would be interesting, as well as an indication of when the heat cycle begins and ends to see the lag time inherent in the system. Setting a heat anticipator on these systems must be interesting. Our house was built in 1950 by an architect just out of school. Cinder block on slab floor ranch, with a poured concrete roof. This is where he learned what not to do. There is a small fortune in 1/2" copper pipe in the floor that was originally heated with a boiler in the utility room and regulated by nests of valves in two cabinets in different parts of the house, the bedrooms separate from the living areas. It wasn't long after they got really sick of continually diddling valves that the concrete ate the copper enough for the leak to inherit the earth, and forced air was retrofitted. This summer, we installed what I think is the forth forced air system. Ron N
