Traditional Underfloor Heating Systems

Traditional underfloor heating systems involve embedding heating pipes or cables within the floor structure, often in a concrete screed layer.

Hercuglas Renewables is listed on the SEAI Domestic Register. NEWS - AVAILABLE GRANTS SEAI !!! New funding ranges from €2,400 to €162,600 to support an even wider range of businesses to switch to solar. This will typically support 20-30% of the investment cost, reducing payback to as little as 2 years. New Solar PV Scheme enhancements will boost business investment in renewable energy generation.

a. PEX Tubing Systems:

  • These systems use cross-linked polyethylene (PEX) tubing to circulate hot water through the floor.
  • PEX tubing is installed in a serpentine pattern across the subfloor, secured with clips or staples.
  • Hot water from a central boiler or heat source is circulated through the tubing, warming the floor and radiating heat upward.

b. Slab Radiant Systems:

  • In this system, a network of pipes is embedded within a concrete slab.
  • The heated water or fluid circulates through these pipes, warming the entire slab and consequently the room above.
  • Slab radiant systems provide a high thermal mass, leading to slower heat-up and cool-down times but prolonged heat retention.

c. Radiators and Underfloor Combination:

  • This hybrid approach combines traditional radiators with underfloor heating.
  • Radiators are used in conjunction with underfloor heating to provide additional heating when needed.
  • Underfloor heating can act as the primary heat source, while radiators provide extra warmth during very cold periods.

a. Heating Mats:

  • Electric heating mats consist of a mesh or fabric with embedded heating cables.
  • The mats are unrolled and laid out on the subfloor, typically below a layer of tile adhesive or self-leveling compound.
  • These mats are particularly suitable for tile and stone floors.

b. Heating Cables:

  • Electric heating cables are installed individually, allowing for more flexibility in design.
  • The cables can be spaced according to heat load requirements and flooring type.
  • They are suitable for a wide range of floor coverings.

c. Foil Heating Systems:

  • These systems consist of thin, flexible heating elements sandwiched between layers of insulation and foil.
  • Foil systems are designed for laminate, engineered wood, or carpet floors.

d. Carbon Film Systems:

  • Carbon film is a thin, self-adhesive heating element that can be applied directly to the subfloor.
  • It's suitable for a variety of floor coverings and is known for its quick heat-up times.

Underfloor Heating - Function

The underfloor heating is a reliable and efficient heating format that combines thermal comfort conditions and economic operation.

In this system, hot water at temperature 35-45 circulates within the piping circuit that is embedded in the floor of the space.

The transmission of heat takes place by radiation from the floor to the heated space, from the lower to the higher layers. Over the entire surface of the area without strong currents. Achieved in this way, the desired temperature stratification, ie at the height of the head temperature rises to 18-20 ° c or lower.

The heating through pipes that run across the surface of the site ensures the basic requirements of modern life that is comfortable and healthy living in conditions of thermal warmth. Aesthetics without limitations in contemporary modern house and environment friendliness, one can easily enjoy saving energy and costs, thanks to underfloor heating.


The heating through pipes that run across the surface of the site ensures the basic requirements of modern life. The major advantages that one can enjoy by installing underfloor heating is:​

  • Thermal comfort and healthy living environment due to uniform heating and lack of dryness in space.
  • Energy savings due to reduced heat loss and operating at lower temperatures (35oC - 45oC). At the same time due to reduced operating costs and maintenance costs of short-term depreciation installation cost is achieved
  • Full exploitation of interior spaces and freedom in shaping them consistently elegant architectural layouts on them.
  • Safer heating without hot surfaces of radiators.
  • Ability combinatorial function with periodic heating areas through fancoil or radiators.
  • Environmentally friendly with the ability to use mild and renewable energies such as solar, geothermal and air pump - water.
  • Ability cooling by adding just the appropriate cold water production mechanism (chiller, heat pump).


1. Design and Planning:

  • Assess the heating needs of the building, taking into account factors like square footage, insulation, and local climate.
  • Decide on the type of heating system you want to install, including underfloor infrared radiant heating.
  • Design the layout of the underfloor heating system, including the placement of pipes and radiant panels.
  • Determine the location for cylinders and tanks, considering factors like accessibility and available space.

2. Gather Materials and Equipment:

  • Procure all the necessary components, including underfloor heating panels, pipes, controls (thermostats, timers, etc.), cylinders, and tanks.
  • Ensure that you have the appropriate tools for installation, such as pipe cutters, wrenches, and electrical tools.

3. Installation

  • Prepare the subfloor for the underfloor heating system. This may involve cleaning the surface and ensuring it's level and free from debris.
  • Install the underfloor heating panels or mats according to the manufacturer's instructions. These will house the heating pipes.
  • Lay out and secure the heating pipes within the underfloor panels. Connect the pipes to the appropriate manifolds.
  • Install the cylinders and tanks in their designated locations, connecting them to the heating system as needed.

4. Connect Controls and Plumbing:

  • Install the heating system controls, including thermostats, timers, and any smart home integration if applicable.
  • Connect the heating system to the electrical supply, ensuring proper wiring and safety measures.
  • Connect the heating system to the plumbing system, ensuring proper water flow and connections to the cylinders and tanks.

5. Testing and Commissioning:

  • Fill the heating system with water and perform a pressure test to check for leaks in the pipes and connections.
  • Test the heating system to ensure that it's functioning as intended. Check the underfloor heating, cylinders, tanks, and controls.
  • Fine-tune the system settings to achieve the desired temperature and efficiency.
  • Educate the building occupants about how to use the heating system effectively.
