Normal? We are still in contact with the kids (now retired) of the first owners. The house was built in 1970 and they can't remember anything like that. In fact, the house had a fairly weak radiant heat system which a later owner simply cut off with an angle grinder (%#&*!!).
Met a neighbor yesterday, they already upped the ante to five cords for next season. Guess we also should have ... or move to another state. In view of the pension funds blowing up around here that may be necessary anyhow.
