Types Of Underfloor Heating Systems

When it comes to underfloor heating systems, there are two main types that you can choose to utilise in your home, electric and hydronic. In this post we will discuss the differences and the benefits of each system.

Electric Underfloor Heating

Electric underfloor heating systems are used only for heating and make use of flexible heating elements such as cables, mats or bronze mesh to transfer the heat. B3ecause they are low profile, they can be installed in a thermal mass or right under the floor finish. They are often used as carpet heaters, portable heaters for under rugs, and other floor warming systems such as shower floors and seats.

Electric systems tend to be simpler to install and commission than hydronic systems, but large scale systems require skilled tradespeople and designers.

Hydronic Underfloor Heating

Hydronic underfloor heating systems use water or a mix of water and anti-freeze as the heat transfer fluid that is passed through a “closed loop”, recirculating between the floor and the boiler.

Hydronic systems require skilled designers and tradespeople familiar with the system components including boilers, circulators, control, fluid temperatures and pressures. Using modern factory assembled sub-stations can simply the design and installation efforts greatly. These are used primarily in direct heating and cooling.

Hydronic systems use a single source or can use a combination of energy sources to produce the heat and manage energy costs. The most common options include:

  • Boilers:
    • Natural gas
    • Methane
    • Propane
    • Coal
    • Oil
    • Electricity
    • Solar thermal
    • Wood or other biomass
    • Bio-fuels
  • Heat pumps and chillers:
    • Electricity
    • Natural gas
    • Geothermal heat pumps
