The SysteMate 2000 is an indirectly heated hot water only thermal store and is
supplied with the factory fitted controls and equipment shown in Section 1.2
Technical Data.
The indirect heat exchanger is highly efficient and designed to provide extremely
quick hot water recovery as well as back-up space heating when using‘Switch’.

Description
1.1 INTRODUCTION
An important feature of this product is that
hot water can be supplied directly from the
mains at conventional flow rates without the
needfortemperatureandpressurereliefsafety
valves or expansion vessels. This is achieved
by passing the mains water through a plate
heatexchanger. Theoutlettemperatureofthe
domestichot water ismaintained byaprinted
circuit board,which controls the speed of the
pump circulating the primary water from the
store through the plate heat exchanger.

The whole system is controlled by a special
electronic control p.c.b. complete with
programmer to which an external room
thermostat can be easily connected.

Any sealed system automatic boiler designed
to operate on an 820C flow and a 710C return
up to a maximum of 35kW can be linked to
anysuitablemodel of SysteMate2000and the
deciding factor is the space heating and the
hot water requirements of a dwelling. See
Section 1.2 Technical Data for further details.
TheSysteMate2000isavailablewiththeoption
of‘Switch’which will provide a 9kW electrical
emergency backup in case of failure of the
main heat source. See section 1.3 System
Details for further information.
There is no facility available to incorporate a
standard 3kW immersion heater for back up
hot water only.
