JG Underfloor 4 Port Manifold connects and centralises underfloor (UFH) pipework in one place and distributes warm water through the pipe circuits to provide even and comfortable heat. When combined with the JG Aura wiring centre and JG Aura heating controls, it also offers independent zone control.
Made from stainless steel, the manifold is manufactured to the highest standards. Fast and simple to install, it has a pre-fitted wall bracket and vibration isolation mount and uniquely features JG Speedfit connections and an integral air vent and fill valve. It also features pre-assembled flow rate indicators for adjusting flow and isolating pipe circuits.
Protective dust caps are supplied on the return rail, which can be removed when installing circuit actuator valves to open and close the flow of water to each pipe loop.

JG Underfloor control unit is used to provide heating to a conservatory or room extension up to 30m². It is suitable for use when the boiler serving the existing heating system has the capacity to take the extra output from 2KW to 3KW and the maximum area to be heated is 30m2 or less.
The unit is pre-assembled and pre-wired to allow for a fast and simple installation. It can be plugged into any convenient electrical socket or spur. It also has integral ball valves for isolation from the primary heating system, an adjustable blending valve and a six-metre head circulation pump.
It should ideally be connected to the main central heating flow and returns distribution system, but it can connect to the nearest radiator supply pipe. In this case, the pump will not operate independently and will only obtain hot water when the radiator system is on.

Always use a JG Speedfit superseal pipe insert when connecting Speedfit pipe to a Speedfit push-fit fitting. Inserts play a vital role in providing extra support to pipework, ensuring that the ends of the pipe are kept nice and round, and minimising any loss of shape that can occur when cutting.
JG Speedfit superseal pipe insert contains dual o-rings to provide even greater sealing security than a standard insert. The first o-ring is on the stem that is pushed into the pipe to prevent water from inside the pipe passing between the inside of the pipe wall and the outside surface of the insert. The second o-ring sits on the end of the insert and seals inside the push-fit fitting, becoming a seal between the main pipe and push-fit fitting. When superseal Inserts are used with Speedfit push-fit fittings a multi-seal is formed as all push-fit fittings also include a main o-ring seal.
2 extra O-Rings provide enhanced sealing
Maintains structural integrity of the pipe connection
