Cost to Hydronic Radiant Floor Heating in Houston, TX (2026)
If you’re budgeting a hydronic radiant floor heating in Houston, most projects run $9,479-$20,854, 5% below the $14,500 national average. What moves that number most is usually one thing: New Construction vs. Retrofit. On its own it can swing the cost by $3,000 - $10,000, so that’s the decision to slow down on before you sweat the smaller stuff.
Easiest place to save: Install during new construction or a major renovation when floors are already open - saves $3,000-$8,000 in retrofit costs
In the South (where Houston sits): Low demand reduces pricing; fewer specialists available.
