Applications / Benefits

Our insulated pipe can be used in a range of applications from new construction, to district and industrial heating and plumbing, to linked utility supply between detached buildings, to an increasing range of new renewable energy applications.

Geothermal heat pumps

Geothermal heat pumps operate on the basis that the earth beneath the surface remains at a constant temperature throughout the year, and that the ground acts as a heat source. They are used for space heating as well as water heating, in residential, commercial or institutional buildings.

Air/water pumps

Air/water heat pumps are based on the fact that heat from ambient air can be boosted to a higher temperature to heat a building throughout the year. They can be used in both residential and commercial or institutional buildings, for both space heating and water heating.

Wood pellet boilers

Using wood fuel instead of fossil fuels makes a positive contribution to the environment. Wood is a carbon neutral fuel; it absorbs as much CO2 when it grows as is released when it burns. Wood pellets are usually compressed sawdust or wood shavings. They are uniform in shape and composition, easy to ignite, create little ash and will flow freely through feeding mechanisms such as hoppers and augers.

Biomass and biogas

Biomass refers to living and recently dead biological material that can be used as fuel. Most commonly, biomass refers to plant matter grown for use as biofuels, but may also include biodegradable wastes that can be burnt as fuel. Biogas typically refers to a gas produced by the biological breakdown of organic materials such as manure, sewage, municipal waste and energy crops. The methane in biogas gives it the ability to be used as a fuel.

 

Benefits

Microflex is a pre-insulated, flexible, energy-saving PEX-a piping system used worldwide that is perfectly suited for transporting water in renewable energy and other heating and plumbing applications.

Unequalled flexibility for easy installation

Microflex pipes are the most flexible PEX-a pipes on the market. Two Microflex pipes of 40 mm can be bent to achieve an internal radius of only 25 cm.

Turning corners and avoiding obstacles has never been easier and leads to significant time and cost savings during installation. With no cutting required, the installer simply and quickly bends the Microflex pipe around the obstacle. And with fewer accessories and connections, there are real reductions in parts and labour, as well as less risk of leakages, and more time to install. Microflex system accessories can be mounted without any special tools.

Unique “closed chamber” design

A corrugated HD-PE twin-wall outer casing (“closed chamber”) protects both the carrier pipe and the insulating material from external influences. It is watertight, resistant to aggressive substances, and shock-resistant even at sub-zero temperatures.

Light weight

As Microflex pipes are light weight, they are easier to handle than comparable pipes, so can be laid rapidly, even over obstacles and around bends.

Highest quality standards

The Microflex piping system is manufactured according to the most stringent standards and Watts Industries manufacturing facilities and processes are fully ISO 9001 approved.

Excellent insulation

Microflex pipes consist of micro-cellular cross-linked polyethylene foam with a closed cellular structure, permitting low water vapour diffusion, good insulation and resistance to extreme temperatures. This positions them favourably against other materials (e.g. PUR foam) which show a decline in their insulation capabilities over time.

Oxygen diffusion barrier

The Microflex carrier pipe used in heating appliances incorporates an oxygen diffusion barrier which prevents oxygen permeating into the piping system. This barrier enhances the life of the system components.

A long, maintenance-free life

Tests carried out by major testing bodies on the different components of the Microflex piping system indicate that the expected lifetime of Microflex pipes is over 100 years. Throughout their life, Microflex pipes are virtually maintenance-free.

Environmentally friendly

The Microflex system is free from pollutants. The pipe imparts neither taste nor odour and is non-toxic. The manufacturing and recycling processes are also environmentally friendly.

Size flexibility

Microflex pipes are available as tailored lengths or full coils up to 100 m. A wide variety of pipe diameters are available from 25 mm o/d (DN20) to 110 mm o/d (DN90) to meet your specific application requirements
