How Much Does Radiant Floor Heating Cost?


Radiant floor heating costs homeowners about $4,000 on average, with prices typically ranging from $1,700 to $6,000. Energy-conscious homeowners are always looking for ways to make their homes more efficient, and radiant floor heating systems are an excellent way to lower utility costs.


When You Should Install Radiant Floor Heating

Electric and hydronic are the two most common types of radiant floor heating systems. Radiant floor heating is suitable for new construction and renovations and is a popular choice for homes in cold climate regions because it’s highly efficient.

Energy Efficiency and Comfort 

Even if you don’t live in a cold climate region, having a nice, warm floor on a chilly morning makes radiant floor heating an attractive option, especially for bathrooms and kitchens. 

Radiant floor heating is more efficient than forced air heating because you don’t lose heat through the ductwork. All the heat distributed by radiant floor heating provides heat directly where needed.

Hydronic radiant floor heating systems powered by natural gas are the most efficient. Water is heated in a boiler and pumped through pipes under the floor. There is even greater energy efficiency when you combine hydronic systems with solar-powered water heaters or geothermal heat pumps.

Suitable Flooring Types

You can use many types of flooring with radiant floor heating. However, some materials transfer heat better than others. 

Your radiant floor heating system will be more efficient if you choose a material with good thermal conductivity. You also want to ensure it’s not too thick and won’t expand or contract. Ceramic, porcelain, natural stone, and concrete floors are considered the best choices for radiant floor heating, but you can also use laminate and vinyl.

The Benefits of Radiant Floor Heating

Radiant floor heating is one of the best ways to heat your home. It offers several benefits over other heating choices.

Comfort and Even Heating

Radiant floor heating is more comfortable because the warm air rises evenly from your floor and is distributed throughout the room at floor level. According to the law of thermodynamics, heat follows cold. Once the heat is conducted from the wires or pipes in your floor to the air in your home, it spreads out in all directions. 

Many homeowners enjoy how clean radiant heat is. Because it doesn’t require blowing air around, you’re less likely to have problems with dust and allergens. 

Energy Efficiency

Many homeowners save about 10 to 30% on their heating bills using radiant floor heating

Many homeowners save about 10 to 30% on their heating bills using radiant floor heating. It’s important to note that radiant floor heating is more efficient in well-insulated homes with low ceilings. 

The heat source is another factor that influences the energy efficiency of radiant floor heating systems. You can significantly lower the radiant heat cost per month using alternative energy sources like solar and geothermal.

Space Saving and Aesthetic Benefits

One of the most significant benefits of radiant floor heating is its unobtrusive. Electric systems are almost imperceptible. The boiler is in a utility room or basement with hydronic systems, so it takes up very little space. Both types operate quietly and cleanly without heat ducts.

Factors in Calculating Costs of Radiant Floor Heating

Here are a few more factors to consider when calculating the costs of radiant floor heating.

Types of Radiant Floor Heating Systems

The two main types of radiant floor heating are electric and hydronic, but you should also consider alternative energy sources like solar, geothermal, and propane.
