Worcester Greenfloor heating
Global responsibility for nature and the environment
As part of the Bosch Group, Worcester is committed to
environmental protection. With product development being
prioritised in the interests of people’s safety, the economical
use of resources and environmental sustainability.
In just a few short years, Britain’s domestic heating and
hot water industry has changed dramatically.
With approximately 25% of the UK’s carbon dioxide
emissions being produced by home energy consumption,
75% of which is for the provision of heating and hot water,
such change is not only inevitable but crucial.
Words and expressions such as “renewable energy”,
“sustainable technology” and “carbon footprint” have
become part of everyday conversation and have been
fuelled by extreme weather and stark television images
of melting polar ice caps.
Worcester, Bosch Group, whilst continuing to satisfy the
daily demands for heating and hot water comfort, has taken
a lead in developing solutions which reduce the impact on
the environment by reducing CO2 emissions – not only for
today but well into the future.
As part of this philosophy we are proud to introduce
high efficiency Greenfloor heating systems. Part of the
Total System Solution offering from Worcester, Greenfloor
heating systems deliver efficient heating in their own right
as well as facilitating the use of low carbon technologies
such as air source and ground source heat pumps and
condensing boilers.
Greenfloor heating is suitable for both new build and
refurbishment applications, offering a number of major
benefits over traditional radiator systems. By operating at
lower temperatures, underfloor heating helps to increase
the efficiency of the boiler or heat pump and reduces
overall running costs. Unlike radiator systems underfloor
distributes heat more evenly, increasing user comfort
whilst helping to reduce dust and the risk of house mites.
Greenfloor provides a complete underfloor heating
package that’s robust and reliable. The range includes
PE-Xc pipe with a choice of different pipe fixing methods
and manifolds for between 2 and 16 zones. These
are complemented by controls and a full range of
other accessories.
The pipe fixing methods are designed to make installation
quick and easy and can be used with traditional sand and
cement screed, wet screed or as a dry construction system
to suit the requirements of each property.

Greenfloor features and benefits
Heat from a radiator travels up and around the
walls and ceiling of a room first, losing much of
its useful heat in the process...
...while the heat from underfloor heating is
evenly distributed from the surface of the floor
throughout the whole living space.
