Can hardwood flooring go over radiant heat?

Engineered wood rated for radiant heat can work, but solid hardwood is generally avoided because the heat cycling causes more expansion and contraction than solid wood handles well.

Does installing flooring over radiant heat cost more?

Yes, it typically costs more than a standard install because of the heat-rated adhesive or thinset required and the extra care needed to avoid damaging the heating elements.

Who installs the heating mats, the flooring contractor or an electrician?

Electric radiant mats are usually installed or wired by an electrician, with the flooring contractor handling the surface material on top. Hydronic systems typically involve a plumber. Many jobs use both trades coordinated together.

Radiant heat flooring installation

Radiant floor heating, whether electric mats or hydronic tubing, is a common add-on in Connecticut bathroom remodels, kitchen renovations, and sunroom additions where a cold tile or stone floor in the winter is a dealbreaker. Installing flooring over a radiant system is a different job than a standard install, since the flooring contractor needs to work around the heating elements without puncturing tubing or damaging electric mats, and use thinset or adhesive rated for the heat cycling.

This is usually a coordinated job between an electrician or plumber who installs the heating system and a flooring contractor who lays the finished surface. Tile and natural stone handle radiant heat well and are the most common choice. Engineered wood can go over radiant heat if it's rated for it, but solid hardwood is riskier because of expansion and contraction with the heat cycling.

What it costs

Cost depends on whether the heating system is being installed as part of the same project or the flooring is going over an existing system, the square footage of heated area, and the material chosen, since tile and stone are more forgiving over radiant heat than solid wood. Coordinating two trades (heating install and flooring install) can add scheduling time compared to a standard flooring job.
