efficiency

The boilers featured in this pocket guide cover
the majority of applications, namely: system,
combi, heat-only and system store. So no
matter what system design the appliance will
be required to power, there is an Ideal boiler
that is perfect for the job.

isar high-efficiency combination boiler

The Ideal isar HE high-efficiency combination boiler
shares the same benefits as its heat-only counterpart but
has all the necessary components incorporated into the
product to enable easy installation to a fully pumped
sealed system.
The boiler is ideal for meeting the heating requirements for
the majority of houses and is available in three models, isar
HE 24, isar HE 30, and isar HE 35.

icos high-efficiency boiler

Thanks to its flexibility of siting, ease of installation and
advanced reliability, Ideal's icos HE high-efficiency boiler is
a further improvement on previous models. It can be fitted
in conjunction with any fully pumped system and is
available in four models, icos HE 12, icos HE 15, icos HE
18 and icos HE 24.

icos system high-efficiency boiler

The Ideal icos system HE high-efficiency boiler shares the
same benefits as its heat-only counterpart, but has all the
necessary components incorporated into the product to
enable easy installation to a fully pumped sealed system.
Available in two models, icos system HE 15, and icos
system HE 24.

istor high-efficiency boiler

A complete heating and unvented hot water system in a
single unit gives a simple and space saving installation.
The Ideal istor HE high-efficiency boiler ensures low
running costs in conjunction with a fast recovery cylinder
for large quantities of mains pressure hot water. The istor
HE is available in two models, the istor HE 260 and the
istor HE 325.

*For outputs exceeding 18kW (60,000 Btu/h), 28 mm primary pipework will be required.

Minimum clearance required at bottom of boiler for servicing is 100 mm, additional clearance will be
required for installation, depending upon site conditions. **More clearance required when fitting fluing
to the side.
Note: This appliance is not suitable for external installation. The wall on which the boiler is being mounted
must be able to support its total weight. The wall will not require special protection, but if the unit is
being fitted in a timber-frame building the guidelines set out in IGE/UP/ 7:1998 should be
observed.
