Few contractors I've worked with have seen a heating setup like ours. Our house was built in the early 50s. We have hydronic heat, copper pipes embedded in the ceiling plaster on the first floor, and in the concrete in the basement floor. The system works great, however; we get cracks in the ceiling where the pipes run. Repairing the cracks is a temporary fix at best. Any advice on a long term solution, other than converting to gas forced air, would be greatly appreciated.
