Underfloor room heating made simple
Hepworth Building Products has launched the Hep2O Underfloor Heating Room System providing an easy option when introducing underfloor heating to a single room within a property.
Hep2O Underfloor Heating - Ideal choice for homes
The benefits of Hep2O underfloor heating for domestic properties are undeniable.
The North Ferriby home has timber joist floors throughout.
Ground floor joists are just 95mm deep so 2mm packers were fixed to the underside prior to fixing floorboards at 90 degrees below the floor joists to cradle 75mm polyurethane insulation.
Aluminium conductor plates were then fixed to the tops of the joists with 100mm wide strips of 25mm polystyrene used to support the edges to improve heat diffusion.
Hep2O Underfloor Heating Pipe from Hepworth Plumbing Products is used to create the heating circuits.
First floor joists are deeper.
Battens are fixed between the joists, set 47mm below the joist tops.
These then support a 25mm layer of polyurethane insulation, again with inset conductor plates, which carry the Hep2O Underfloor Heating Pipe.
Other services including electrics and hot and cold water services are then run in the void below the insulation and above the downstairs ceiling.
The modern extension has a solid concrete floor, with the underfloor system installed prior to pouring of the screed.
The specification at first floor level is similar to that used in the original parts of the property.
The majority of the rooms within the property have timber laminate flooring but underfloor heating can be used efficiently with most floor coverings.
In this case, the homeowner has undertaken a full refurbishment involving most aspects of the interior and replacement of ceilings.
However, underfloor systems can today readily be installed in existing properties simply by lifting the floorboards - total refurbishment is not a pre-requisite.
Until quite recently, underfloor heating has tended to be viewed as mainly appropriate for new construction and at ground floor level, where pipes can be buried within the concrete screed.
However, today's systems and installation approaches mean it is possible to choose underfloor almost anywhere that traditional radiator systems might otherwise be used.
