Getting The Radiant Heat Back

Given that it’s -4F outside right now, it seemed like a post about the heating system we use in the house – and some repairs I had to do to it – was appropriate. This is the (somewhat long) story of repairing one of the signature features in our house: the in-floor radiant heat on the lower level.

As a split-level house, we have one floor (family room level) that is concrete slab-on-grade. There is one problem with slab-on-grade construction in the Northeast: the concrete gets painfully cold in the winter. When designing the house, my grandfather was aware of this fact and had installed Рin 1959 Рradiant heat tubing embedded in the concrete. With the radiant heat, warm water is pumped through the piping and keeps the floor (and the room) warm.

Because of the radiant heat, the house was also outfitted with hot water baseboard heat on all levels, separated into three zones (one for each level – no heat in the basement.)

There was, however, a problem with the radiant heat in winter 2009. My grandmother had called and indicated that the family room with the radiant heat was very cold and that she had called a local plumber to take a look. This plumbing outfit took a look at the radiant configuration – copper tubing embedded in concrete dating to 1959 – and told her that it was broken beyond repair. They really didn’t do any testing or anything, they just assumed it was bad and told her the best option was to install some (very ugly) hot water baseboard radiators in that level of the house.
