M&E Event - New from JG Speedfit
Published:  07 October, 2008

JG Speedfit will be showcasing their plumbing, heating and underfloor heating systems which are easy to use, quick and cost effective.

The flexible pipe can be threaded through concealed or difficult to reach places easily and with over 200 products in the range, Speedfit has a solution for all your plumbing and heating needs.

Amongst the array of products on show will be the new Speedfit Grey range. Both Grey and the traditional White pipe and fittings are WRAS approved and are Kitemarked to BS7291 Parts 1, 2 & 3, Class S.

In addition to the new range they will be showcasing the Speedfit Underfloor Heating System which has been designed to be as simple as possible to install, requiring minimum installation effort and very little maintenance. Component parts have ease of installation built in and are manufactured to UK and European Standards including ISO9001 and DIN4726.

The Manifold for instance, with models available in 4 to 12 zone patterns, comes fully assembled with wall brackets, screws and plugs so it is easy to fix straight on to the wall.

A unique feature of the Speedfit Manifold is that flow and return pipe connections are Speedfit Push Fit so pipes can be connected in an instant, offering much reduced installation time. Flow and return rails are off-set and the angles can be altered further reducing installation time.

The Pump Pack, made up of a modulation pump, mixing valve and overheat temperature thermostat is fully assembled and pre wired. Simply take it out of the box and it is ready to use.

Weighing only 5.8 kilograms the compact pump pack can be installed in limited space and requires no bracket as it can be held in place by the manifold set. Flat face unions make for an easy pump pack to manifold connection. Where space is really at a premium, Manifold Elbow Connections allow for the Pump and Manifold to be installed at 90Þ to each other.

The Speedfit System has water pumped from a heat source to a pump pack, where it is mixed to approximately 50ÞC then distributed via a manifold to heating circuits made using Speedfit Barrier Pipe, the temperature and volume of water constantly alter to maintain the requirements of the system. The pipe is laid in concrete or suspended just below the surface of timber flooring.

The floor is typically warmed to between 25ÞC and 28ÞC, providing an even distribution of heat at just above room temperature. A thermostat will signal the pump pack when heat is required.

The Speedfit System is suitable for most floor finishes including ceramic tiles, carpet, vinyl and laminate. The thermal resistance of floor covering will have a marked effect on the performance of the heating system, advice on the use of floor coverings and their effect on the performance of a system is available from the Technical Help Desk.

Because underfloor heating operates at a lower temperature than radiators, it is more economic to run and especially suitable for alternative heat sources such as heat pumps and solar panels.
