In-Floor Heating and Brazilian Cherry Hardwood

My ex-wife’s sister, Franca, wanted a finished basement rec room back in '08. I told her forced air was a mistake down there. You need boiler-fed PEX tubing under six inches of wire-mesh reinforced concrete.

I tied the rebar and did the pour myself.

"Thermal mass," I told her. "It takes seventy-two hours just to warm the slab." I didn't tell her it takes a full week to cool down once the boiler fails.

Fast forward to last December. Franca called. Said the circulation pump was vibrating like a cheap soil compactor.

I walked through her front door to check on it, keeping my Baffin boots on. I dragged half the Thunder Bay municipal road salt order with me, leaving a heavy trail of white calcium rings across her imported hardwood.

My ex-wife happened to be sitting at the kitchen island. She looked at the salt rings, then looked at me. She stopped calling me right around the time I bought my first Fender acoustic, and her stare proved that absolutely nothing had thawed between us.

I went downstairs to avoid the silence. The manifold pressure gauge read sixty PSI, but the pump was dead. The water was trapped in the plastic piping. Cold and stopped.

You can blast a propane tiger torch at a thick slab all day, but you cannot force a cure with an open flame. Some foundations are designed to store way more heat than they ever let go.

Engineers call it a thermal flywheel. I just call it a hazard of the trade.
