Underfloor Heating

How It Works

Underfloor heating works through warm water pumped through pipes laid in the floor of the room. Much lower water temperatures are required as the large surface area of the floor is enough to warm the room efficiently as the heat rises. An underfloor heating system will generally run at around 35 degrees as opposed to 70 degrees used in radiator systems, which means that there are energy and running cost savings, especially when used with renewable heat sources such as heat pumps.

Why Use Underfloor Heating?

There are a huge number of benefits to using an underfloor heating system, here are just a few of them:

  • Comfort – A correctly designed and installed system runs efficiently and supports the bodys natural requirements for warm feet and cool head. The heat is uniformly rising from the floor, rather than having warm pockets around radiators
  • Aesthetics – Underfloor heating creates complete freedom of interior design with no radiators to worry about, you can use every square inch of space can be used for room layouts
  • Silence – Underfloor Heating is virtually silent when running
  • Low Maintenance – No need for manual operations, such as bleeding or painting radiators
  • Cost effective – Lower water temperature means lower energy, means lower heating bills
  • Individual room control – Rooms are heated on an individual basis – for example the bedroom can be at a different temperature from the living room
  • Healthy living – Slower moving air particulates makes underfloor heating the system of choice for asthmatics. Floors dry quicker after cleaning, reducing slip hazard. Underfloor heating also eliminates the risk of contact burns and collision damage from radiators
  • Environment – lower fuel usage means lower CO2 emissions, better for the environment


1 World Solar can install underfloor heating using a wide range of floor constructions including:

Solid Floors

The Underfloor Heating pipes are laid onto insulation board placed over a solid concrete base. Screed is then poured over the top of the pipes. This construction is typically used on ground floors or beam and block floors.

Suspended Floors

Manifold System

A bubble aluminium foil laps up and over the joists to create a sealed air void. The aluminium foil reflects the radiant heat up to the underside of the floor, which in turn heats the room.

Aluminium Heat Emission Plates

These are supported by the joists (400mm c/c). The plates are grooved so that the underfloor heating pipework can be fitted. The plates diffuse the heat for even heat distribution across the floor.

Floating Floors

We can supplies a range of polystyrene panels in various density grades. The panels range from 30mm to 100mm depending on the solution required. The panels are pre-routed so that heat emission plates can be laid directly into the panels. Once this is complete the pipework can be installed into the plates. A floating floor is then laid over the top of the system.
