All You Need to Know About Floor Furnace

Floor furnaces are exactly what the name describes – furnaces in the floor. Floor furnaces radiate heat and provide comfortable interior temperatures through convection.

Although HVAC sets are installed in all or most modern houses, floor furnaces are a great option for homes that do not have a duct system and for homeowners who want to save money.

Types of Furnaces

Floor furnaces operate on propane, natural gas or electricity. Alternative options are available, such as geothermal furnaces, oil furnaces, and solar powered furnaces. These help homeowners reduce their monthly energy bills as the furnaces do not use electricity.


For those who already have furnaces in place, are looking to upgrade their home heating or don’t have a duct system, floor furnaces are cost-effective, simple solutions. Many types don’t require electricity and floor furnaces are way cheaper than regular furnaces.

They provide adequate heating to the room when they are centrally located and are installed in a place where there are fewer footfalls so heat can be radiated constantly.

Installation Costs and Saving

Installation costs depend on the size of the house, the size of the furnace being installed and the energy efficiency it provides.

The average installation cost could range from $3,000 to $4,000. Apart from this, the HVAC professionals you call for the task may require extra material like lumber or dry wall tools.

This can raise the expenses a bit. But installations can take up to eight hours and need to be done perfectly.

So, it is advised that you always approach a professional company to do it. Choose a floor furnace that has an Annual Fuel Utilization Efficiency (AFUE) rating of at least 70% so that you can ensure energy efficiency and save money on operational costs in the future.

Safety Features

Any floor furnace being installed at home must be completely safe. If you are opting for a new floor furnace to be put it or are upgrading your current one, choose one with removable floor furnace grills.

This might seem like a minor feature but it is handy when you need to clean the grill and can increase efficiency of the furnace.

In addition, select a floor furnace that has a large diameter gas flue which will carry harmful gases like carbon monoxide outside your house and prevent any leakage.

Old floor furnaces had only ‘On’ and ‘Off’ as the default setting.

Having an adjustable heat setting for your floor surface is important so that you are not consuming energy unnecessarily. It is also safer to turn the furnace heating down when there are children in the room. Having this feature may cost a bit more but it is worth it.


Homeowners must regularly follow certain maintenance tips to ensure that the floor furnace functions well and is energy efficient.

Change the air filter every thirty days in the winter. Remove air vent covers and clean them with a damp cloth from time to time. You can also use a vacuum hose to clean the dust in the vents.
