2000
The BoilerMate 2000 shown schematically above is designed to provide improved
space heating and mains pressure hot water when coupled to any remotely sited
condensing or non condensing boiler.
A report by the Cranfield Institute of Technology found that this system gives a
potential for energy savings of up to 15%.
Because of the efficiency of the appliance improved SAP ratings can be achieved.
Further details are available from the Gledhill Technical Department.
The principle of a BoilerMate 2000 is to separate the heat generator e.g. a boiler
from heat emitters (radiators) by a thermal store, which evens out the fluctuating
demands for heating and hot water. Thus, by storing energy produced when the
demand is low and discharging it when the demand is high (i.e. during property
warm up or when hot water is drawn off), a smaller boiler can potentially be used.
An important feature of this concept is that hot water can be supplied directly from
the mains at conventional flow rates without the need for temperature and pressure
relief safety valves or expansion vessels. This is achieved by passing the mains
water through a plate heat exchanger. The outlet temperature of the domestic
hot water is maintained by a printed circuit board, which controls the speed of
the pump circulating the primary water from the store through the plate heat
exchanger.
Because of the innovative method of hot water production no in-line scale reducer
is normally required on the cold supply to the appliance.
If scale should become a problem the plate heat exchanger is easily isolated and
replaced with a service exchange unit

Description
1.1 INTRODUCTION
The pcb also incorporates the facility to operate
the heating pump for a few seconds every few
days when the heating is not being used, to
reduce the likelihood of the pumps sticking
as well as providing a boiler pump overrun
facility.
Any automatic boiler designed to operate
on an 82
0 C flow and a 71 0 C return up to
a maximum of 35kW can be linked to any
suitable model of BoilerMate 2000 and the
deciding factor is the space heating and the
hot water requirements of a dwelling. See
Section 1.2 Technical Data for further details.
The BoilerMate 2000 is available with the
option 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.
Gledhill are part of the ‘Benchmark’ scheme
and a separate commissioning/service log
book is included with the product.
