UNDERFLOOR 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°C then distributed via a manifold to heating circuits made using Speedfit Barrier Pipe. The temperature and volume of water is altered to maintain the requirements of the system. The pipe is laid in concrete or suspended just below the surface of timber flooring. A wide range of...

Underfloor heating provides the most comfortable, even warmth of any heating system. It is economical to run and virtually maintenance free. Warm water from a heat source such as a boiler or heat pump is distributed via a manifold to heating circuits made using Speedfit Barrier Pipe. The pipe can be installed in a screed, floating or suspended timber floor. In screeded floors, the pipe is laid on insulation and then covered with a screed which can be laid almost any type of floor covering. For timber floors, spreader plates are laid between the joists and the floor decking or on the...

FEATURES & BENEFITS The Speedfit Underfloor Heating System offers many benefits to the consumer. These include: Efficiency Savings Underfloor Heating Systems are designed to operate at lower temperatures than radiator systems, making them especially suitable for condensing boilers and heat pumps. This results in reduced energy consumption and lower heating costs for the building. Installation It is simple to install, requiring the minimum of installation effort and little maintenance. Comfort The system uses mainly radiant heat, the most comfortable form of heating, giving an even...

Theoretically ideal heating Underfloor Heating Radiator heating on inside wall As the chart above shows, people are more comfortable when their feet are in a warm area and their head is slightly cooler. A system using radiators will have colder air at the bottom of a room which places your feet in the wrong place for comfortable living. This is because cold air is more dense (heavy) and it is pulled downwards by gravity. In contrast, Underfloor Heating heats the whole floor. This means that the warmest space is the area nearest the floor, which matches the preferred heat profile. UNDERFLOOR...

PREPARATION CONSIDERATIONS

PLANNING AND ORGANISING YOUR PROJECT The design of an underfloor heating system has a direct link to its output and efficiency. Careful consideration should be given to underfloor heating at an early stage in any project as the system needs to be integrated with construction and building programmes. The key to a successful installation is to invest time in planning the system. If your system has already been designed and you are ready to start your installation, it is useful to ensure you have covered all the points below. For example, the builder or architect needs to ensure that...

If you are new to installing Underfloor Heating, you need to understand that the floor construction will normally determine the way in which the system is installed. There are several options available to suit both new build and renovation projects. Before commencing work, it is important to take some time to familiarise yourself with the steps needed for the floor construction you are working with. Solid floors already have a requirement for insulation and screed. The pipework is fitted to the insulation using clips, staples, or using a number of other alternative methods. Once the...

PRODUCT CHECKLIST UNDERFLOOR HEATING MANIFOLD Manifolds distribute the heating water to each heating circuit in the system and allows the isolation and flow rate setting of each circuit. A unique feature to JG systems is that connections to the heating pipes are Speedfit push-fit, offering much reduced installation times. All manifolds are pre-fitted with brackets, vibration isolation mounts, and an automatic air vent. Flow rate indicators include the means to adjust flow rate and isolate the circuit. The Manifold can be assembled to suit left-hand or righthand supply depending upon project...

A pipe layout plan is supplied with each project upon request. The drawing shows all the important information to correctly install the Underfloor Heating pipework and Manifolds. There are also details of flow rates, pipe spacing and routing of pipe from the manifold to each heated zone. Before starting the installation, it is important to check that the drawing matches the site conditions as any deviation could result in the need to revise the plans and potentially the underfloor heating materials required. The manifold location and position of permanent fixtures such as kitchen units,...
