Emmeti Radiator Manifolds
The advantages
Heating manifolds, unlike today’s common practice of non-manifold ring heating circuits, allow independent circuits thermally different to each other. This is because they supply flow and return water directly to each radiator, in a star pattern. This makes it easy to hydraulically balance each independent circuit.
Taking into account pipe runs, the hot water is circulated to all the radiators at the same time. This avoids the balancing or sequencing issues with a non-manifold system, where one radiator can be producing maximum heat well before another has started. A more constant temperature across all manifolds circuits is maintained (providing the balancing is done correctly).
Manifolds encourage the use of small diameter pipes, 10 mm or 12 mm, PB, PEX or Multilayer. This type of pipe is easy to handle and flexible. No further connections are required between the manifold and the radiator. The connectors on the radiator and on the manifold are mechanical. This means that there are far fewer joints in total and none at all which are concealed so leaks are kept to a bare minimum and because they are not concealed, relatively easy to locate and deal with.
Manifold Types
To make understanding the Emmeti range of heating manifolds easier, we have organised them into three simple types, matching each type to a heating system and controls to make the application clear.
Type 1 (T1):
These are for wall hung radiator (WHR)systems with a Thermostatic Radiator Valve (TRV) and Lockshield valve (LS) on the radiator.
Type 2 (T2):
These are for either wall hung radiator or underfloor heating (UFH) systems. The manifold is fitted with an electrothermic valve and lockshield to control each circuit; this replaces for example the TRV and LS on a radiator. The electrothermic valves are controlled by a thermostat or programmable thermostat, via a wiring centre.
Type 3 (T3):
These are underfloor heating (UFH) systems only and have a temperature controller and pump to ensure that the water is at the correct temperature for the underfloor heating circuits, and there is sufficient flow for the greater amounts of pipe used.
Each type has its own section and further details of each manifold are given under each of the product headings.
