Greenfloor heating
Worcester's Greenfloor heating system uses a water-filled
pipe system that turns the floor into a large surface area
radiator. The pipe system gently warms the space above it
through a combination of radiant energy and heat conduction.
In a modern, well-insulated space where heat loss factors
have been taken into consideration, underfloor heating can
act as the primary heating source and, in most cases, no
other space heating methods will be required.
Underfloor heating operates with lower water temperatures
than traditional radiator systems. This makes it the perfect
complement for Worcester's ground source and air to water
heat pumps. As well as space heating, Worcester heat
pumps are able to provide a constant supply of hot water
throughout the year.
The low return water temperature of underfloor heating
also makes it suitable for use with Worcester condensing
boilers, ensuring they remain at their optimum efficiency,
with significant energy savings.
As there are no radiators to take up space, Worcester
Greenfloor systems also provide maximum flexibility within
the property. They can also be used with a wide range of
floor coverings, including parquet, carpeting, marble or tiles.
Underfloor heating is a system where every component is
important to overall performance. Worcester Greenfloor
systems provide a comprehensive selection of high quality
system components, while offering considerable flexibility
to meet all of a project's needs.

Greenfloor PE-Xc system pipe
The Greenfloor PE-Xc system
pipe is oxygen impermeable
and highly flexible for ease
of installation. The pipe is
available in two sizes to
suit the panel system
(see table below).

Pipe positioning panel
Stapler panel systems
Dry construction system
Timber suspended floor
System pipe is available in coils, with a reel available to ease
unwinding, reduce waste and avoid the need for couplings.
