JG Speedfit Underfloor Heating Videos

Speedfit Underfloor Heating LogoThe following videos show step-by-step how to install JG Speedfit underfloor heating and the various different ways in which this can be achieved.

The Speedfit system for Underfloor Heating has been designed to be as quick and easy as possible to install with component parts manufactured under an ISO9001 Quality Management System. The system has water pumped from a boiler or other heat source to a pump pack where it is mixed to approximately 50° then distributed via manifold to heating circuits made using Speedfit Barrier Pipe.

JG Speedfit Underfloor Heating - An Introduction (Video)

JG Speedfit Underfloor Heating - An Introduction


This first video gives a general overview and acts as a welcome to JG Speedfits underfloor heating video tutorials. It outline briefly why underfloor heating (UFH) is the ideal solution for today's needs and takes you through the various UFH systems, such as the staple, mounting rail, and floor panel systems for solid floors, the underfit and overfit systems for instalation over existing floors and the two heat spreader plate options for use with suspended floors.




How to Install the JG Speedfit Underfloor Heating Manifold (Video)


This in depth video tutorial covers the instalation of the JG speedfit Underfloor Heating manifold. The manifold performs a number of functions, primarily distributing hot water from a central location to various rooms in the house and this video covers such topics as the use of numerous circuits and how they are isolated and adjusted.

It shows how speedfit pipe is connected to the manifold and takes you through the various fearures of the manifold and clearly shows the role of actuators, flow meters, mixing valves and the control pack. There are also step by step instruction on how to to balance the system as well as the procedure for filling and pressure testing the manifold.

How to Install JG Speedfit Underfloor Heating Using the Mounting Rail System (Video)

!
This video tutorial covers the instalation of Underfloor Heating using the 'JG Speedfit Mounting Rail' system. Firstly the video takes you through the preparation of the floor, the use of multiple cicuits and the instalation of cicuits using the rails that are fixed by using their double sided sticky taped backing to the floor insulation.

The video shows the pipe being fitted in a 'serpentine' pattern, and concludes with information about the different kinds of screed that can be used and the approximate drying times that will be needed.

How to Install JG Speedfit Underfloor Heating Using the Staple System (Video)


This video tutorial covers the instalation of JG Speedfit Underfloor Heating using the 'Staple' system which is particularly well suited to large instalations in irregular shaped rooms. Firstly the video takes you through the preparation of the floor, the use of multiple cicuits and the instalation of cicuits using the staples and the custom-manufactured JG Speedfit Staple Gun that fires the 40mm or 60mm staples to safely and securely fix the barrier pipe to the floor insulation.

The system works best with a second person feeding the pipe from the coil as the first person secures it and the video shows the pipe being fitted in both a 'Serpentine' pattern that uses rows of straight parralell lines reurned at the end of each run, and a 'Counterflow' pattern that moves into the centre of the circuit in a spiral and then performs a double return at that point and spirals back out to the edge of the room.

The video then concludes with information about the different kinds of screed that can be used and the approximate drying times that will be needed.

How to Install JG Speedfit Underfloor Heating Using the Floor Panel System (Video)


The JG Speedfit Foor Panel system lends itself to large instalations in regular shaped rooms. Firstly the video takes you through the preparation of the floor, the use of multiple cicuits and the instalation of the cicuits using the black speedfit floor panels.

The panels make laying the pipe a one man job and the panels can be easily cut to size or simply overlapped and pushed together and the use of the new Speedfit Layflat Barrier Pipe makes installations using this method even easier still.

The video shows the pipe being fitted in both a 'counterflow' and 'serpentine' pattern, and concludes with information about the different kinds of screed that can be used and the approximate drying times that will be needed.

How to Install JG Speedfit Spreader Plate Underfloor Heating System (Video)


This JG Speedfit video tutorial covers the instalation of the spreader plate systems of underfloor heating. These are suited for use with suspended floors or fitted onto battens. They can even be fitted from below if required. When using this system you may need to minimize heat-loss by fitting extra insulation between the joists. If the JG Speedfit spreader plates are used over suspended floor then the pipework from the manifold can be routed through the joists as with conventional plumbing pipework.

The video covers preparing for the plates, installing them with a 25mm gap between plates. spreader plates can be cut with a jigsaw or scored with a sharp knife so they can be snapped by hand. The Layflat pipe fits tightly into the grooves and some force will be needed.

How to Install JG Speedfit 'Overfit' Underfloor Heating System (Video)


The JG Overfit system of underfloor heating is designed to be used with lightweight floor coverings such as laminate or engineered wood or carpet. It uses the JG Speedfit overfit boards which are lightweight insulated panels with a high compressive strength. One of the main benefits of this system is that it can be fitted over existing concrete floors.

This video takes you through how to lay the panels and join then with JG Tape, and outlines the differnet kinds of flooring and how they can be used. Togue and groove flooring can be used for example if battens are fitted to the overfit panels and tiles can be used if a heavy 'backer board' is used.

The Speedfit Technical Team Explain The Advantages Of Using Layflat Pipe (Video)


The new 'Layflat' pipe from Speedfit has a number of advantages. Primarily the increased flexibility makes jobs like cabling through joists almost as easy as fitting electrical cable. The pipe has a barrier to prevent the ingress of oxygen into the underfloor heating system and comes with the JG Speedfit 25 year guarantee.

When it is removed from the coil it keeps straight and lays flat unlike other pipe that will try to coil back into place and has to be wrestled into position. It is lead free and non-toxic and is manufactured in the UK to Bristish Standards BS7291 parts 2 and Class S.
