SystemZone is a patented distribution manifold for use in zoned heating systems. It contains all the elements for correct system installation. Also available in commercial sizes up to 3" BSP
SystemZone has many unique features:
SystemZone is ideal for simplifying many complex installations.
Here are a few examples:
Large Boiler Arrays
Here SystemZones are used to collect water from multiple boilers and to distribute it to multiple heating zones.
Installation of a boiler array is less expensive than one or two large units with tall chimneys.
Multiple Systemzones and the SystemLex Wiring Centres can be cascaded together very simply to create an installation as large as you wish to.
Small Boiler Arrays
Here is a smaller boiler array suitable for a large dwelling or small commercial premises.
The boilers in use in an array will work most of the time at their optimum load and therefore will be most efficient.
Boilers also act as back-up for each other, allowing for maintenance and repair while keeping the system running as normal.
Simple Renewables Integration
Integrating renewable energy sourcesSystemZone is excellent for complex systems with a variety of heat sources and different heat emitters.
Here is a typical installation with an air-to-water heat pump, a back-up boiler (gas or oil), solar powered hot water with underfloor heating and radiators.
The illustration shows the SystemZone incorporated in the SystemLink Zoning Centre.
Solid Fuel Installations
Solid fuel combinationsSystemZone is ideal for systems where different heat emmitters are combined, such as solid fuel and oil or gas.

Benefits of SystemZone
SystemZone greatly simplifies design, installation and control of heating zones
Zone and boiler circuits are independent of each other
SystemZone's unique patented design ensures that each boiler and heating zone operates independently of all others. When the pump in a particular zone or boiler circuit is inactive, no water moves in that circuit. This is achieved without motorised valves and with all waterways open at all times. No other method achieves this result.
Safety is assured
Safety is guaranteed as no waterway is ever blocked by a valve. No separate bypass is required.
The hottest water is used for heating without any mixing
SystemZone's patented heat stratification system allows each zone to draw from the hottest water at the top layer of the unit. This makes for efficient operation and fast heating.
Automatic neutral point created
SystemZone automatically creates a neutral point within the unit. The neutral point can be difficult to locate in conventional plumbing layouts.
Simple layout and design
System design and implementation is greatly simplified with SystemZone, as each zone or boiler circuit can be planned as an individual module without needing to consider its effect on the rest of the system.
Less expensive installation
With SystemZone, fewer parts, simpler design and easier fitting significantly reduces installation costs.
Different flow rates automatically catered for
A further advantage of the independence of each circuit is that different flow rates can be specified without creating any conflicts provided that the primary pump is sized to cater for the total flow rate leaving the manifold. This makes it easy to create mixed systemswith a variety of heat sources and heat emitters.
Efficient, continuous air extraction
The water entering the SystemZone slows down because the units cross-sectional area is many times greater than that of the pipes feeding it. This allows any trapped air to accumulate at the top of the unit where it is continually extracted by an automatic air vent. The pumps in the system therefore work with maximum silence and efficiency, air locks are minimised and radiators are much less prone to need bleeding.
Reliable, no moving parts
As SystemZone has no moving parts, reliability is guaranteed.
