How Much Does It Cost to Put Radiant Floor Heating in a Foundation?

Hydronic System

• If you want to put a radiant heating system into your foundation while you are building a house or addition, you will need to use a hydronic system. This version cycles warm water through pipes in the foundation so the heat can be released up into the rooms. Because of the installation requirements and the water heater, this system is the most expensive version, but it is also one of the most economical over time.

Per Square Foot

• According to the Cost Helper website, the average per square foot for a hydronic radiant floor system is between $6 and $14. This is for a professional installation, which is typically the only option available. Because the pipes need to be installed as the foundation is created, you will need to hire a contractor with radiant heat experience to complete the project.

Total Costs

• Cost Helper reports that total costs for the hydronic project for a typical 1,500 square foot home come out between $9,000 and $22,000. The large range occurs because of the complexity of the project. However, the lower end is more common if you are planning to install radiant heating with new construction. The costs increase when you factor in full foundation remodeling for an existing house.

Variance

• Some variance is common in radiant heating system costs. One primary reason is the complexity of different systems. If you want a number of different temperature zones and a large system, costs will be much higher. Also, some estimates include the cost of the water heater, while others leave the heater as a separate expense.
