What Does Radiant In-Floor Heating Cost?

One of the factors affecting the cost of an in-floor radiant heating installation is the method that will be used to heat the hot water.

On small-to-medium sized residential projects we are often able to use your existing hot water heater. We install a unit called a "radiant X-Block" (X-Block). This pumps hot water from your water heater, through a heat exchanger, to heat your floor. The water in the floor does not come in contact with the rest of your hot water. The cost of the X-Block and installation is approximately $3000.00.

With a larger project, a full boiler system must be installed that can heat your radiant, domestic hot water, pool, driveway, etc. A boiler room build will typically cost approximately $13,000.00.

When a gypsum pour is required, there are some minimum costs involved that ultimately make the per square foot costs somewhat higher on smaller projects.

Radiant heating system installations that take place during the construction of a new home tend be more cost-efficient compared to retrofits into existing homes or installations during renovations.

Below are a few samples of typical projects you can use to get a ball park idea as to costs.
