Each of Ideal's HE boilers contains only those parts that are necessary to
deliver dependability and performance, or that make the product easier to fit,
operate or install. As a result, they all offer exceptional levels of reliability and are
easily maintained and serviced.
Common components
Many Ideal HE appliances share a wide number of common parts making them
easier to install, service, and maintain. These items include components such as the
gas valve, burner, venturi, fan, fluing system and controls.
Easy siting
All Ideal HE appliances are available with a wide range of flue options. These make
siting the boiler in the property easier as long flues can be used. It also makes
positioning the flue terminal easier.
Simple to fit and service
Because they have so much in common, fewer spares are required to maintain the
range of boilers.
Most products are `self-adjusting'. This allows the installer to fit the products without
the need to make any alterations. The boilers, being fully modulating, (classic HE
excepted) adjust themselves to the required output to meet the heating load.
Unprecedented reliability
We have introduced new test procedures which are comprised of a demanding series
of application tests to ensure that the boiler is fault-free.
We have never been tougher on ourselves or our products, and you will find that it
shows in the new standards of reliability which these products have attained.

To comply with Part L of the Building Regulations 2005, Building (Scotland)
Regulations Section 6 or Northern Ireland Building Regulations Part F domestic
boilers are required to meet minimum SEDBUK ratings of 86%.
SEDBUK - Seasonal Efficiency of Domestic Boilers in the UK
The SEDBUK efficiency of a domestic boiler is an approved method of representing
the energy efficiency of a boiler under assumed typical operating conditions.
A boiler's efficiency is calculated using the SEDBUK rating (Seasonal Efficiency of
Domestic Boilers in the UK). This rating defines the average annual efficiency of a
domestic boiler achieved in typical domestic conditions, making reasonable
assumptions about pattern of usage, climate, control and other influences. SEDBUK
efficiencies are banded A-G (with A being the highest). The Ideal products icos HE,
icos system HE, mexico HE and imax W are SEDBUK A rating approved with energy
ratings over 90%. They are all Energy Efficiency List recommended. The classic HE is
SEDBUK B rated with an efficiency greater than 86%.
These high-efficiency boiler ranges meet the requirements of the Building
Regulations 2005.
Ideal Boilers Ltd hereby declare that the boilers listed below meet the essential requirements for heating plant as described in:

The Ideal high-efficiency heat-only boiler
The icos HE boiler combines a modern, stylish exterior with highly reliable
engineering, resulting in an appliance that is easily installed and requires minimal
servicing and maintenance. This advanced, dependable product looks at home in
any environment and offers years of trouble-free service, as well as a reduction in
gas bills.
Application and usage
Flexibility of siting, ease of installation and advanced reliability all mean that the icos
HE offers further improvements on previous models. A telescopic flue is standard for
concentric installations. The 80mm diameter twin-pipe fluing feature offers a
maximum combined fluing length of up to 60 metres that can be run horizontally or
vertically, so it can now be fitted safely and unobtrusively in almost any situation.
Compact 60mm diameter twin-pipe fluing feature systems are also available, along
with a range of high level fluing options. Condensate drainage is overcome using the
optional Ideal condensate pump kit.
The icos HE in operation
The icos HE is an automatically controlled, fan-flued high-efficiency boiler. It
modulates heat output to suit the demands of the heating load, incorporating a
variable thermostat for CH temperature control, adjustable from 30ºC to 82ºC.
The pre-mix burner allows control of gas input to the appliance to be linked to fan
speed; as the fan reduces speed to match heating load, the gas valve maintains the
correct proportional flow, ensuring high efficiency throughout its output range.

Fully Pumped Sealed System
The Ideal high-efficiency system boiler
The icos system HE boiler from Ideal features a contemporary, stylish exterior with
simple yet highly reliable engineering. The boiler is easily installed, and requires
only minimal servicing and maintenance. It is an advanced, dependable product
which fits into any environment and offers years of trouble-free service, as well as
a reduction in gas bills for the homeowner.
Application and usage
The icos system HE offers flexibility of siting, ease of installation in sealed systems
and advanced reliability. A telescopic flue is standard for concentric installations. The
80mm diameter twin-pipe fluing feature, offering a maximum combined fluing length
of up to 60 metres that can be run either horizontally or vertically, means the boiler
can be installed much further away from the outside wall. This allows the boiler to be
fitted safely and unobtrusively in almost any situation, whilst condensate drainage
can be overcome using the optional Ideal condensate pump kit.
The icos system HE in operation
The icos system HE is an automatically controlled, fan-flued high-efficiency boiler,
modulating its heat output to suit the demands of the individual heating load. It also
incorporates a variable thermostat for CH temperature control, adjustable from
30ºC to 82ºC.
The use of a pre-mix burner allows control of gas input to the appliance
to be directly linked to fan speed. So, as the fan reduces speed to match heating
load, the gas valve maintains the correct proportional flow ensuring a high boiler
efficiency throughout its output range.

icos HE 12-24 &
icos system fluing options
The heat-only HE range from Ideal
boilers benefits from a wide variety of
fluing options, making it possible for
the installer to fit each unit safely and
unobtrusively in almost any situation.
The following information sets out the
alternatives that are available and
demonstrates the siting flexibility that
is an inherent part of all our boilers.
The Ideal HE range comes with a
choice of concentric or twin-pipe
fluing options.
Twin-pipe fluing
Various twin-pipe options are available,
in both 80 mm and 60 mm diameters,
to assist in the termination of the flue
where the boiler is installed in a location
remote to an outside wall. These
options allow for separation of the air
supply from the pipe that discharges
the flue gases. All twin pipe flue
installations MUST be fitted with the
condensate drain trap supplied.
80 mm twin-pipe system
The maximum combined flue length
is 60 metres. The following graph
(FIG. 1) demonstrates the allowable
lengths for the air supply and flue gas
pipes. This system can be used for
both horizontal and vertical
applications.
60 mm twin-pipe system
The maximum combined flue length
is 18 metres. The following graph
(FIG. 2) demonstrates the allowable
lengths for the air supply and flue
gas pipes. This system can be
used for horizontal applications only.

High level flue outlet kit
High efficiency flue terminals produce a plume of vapour which can be a nuisance
at certain installations. To solve this, we have developed high level flue terminals
which are out of normal view. See pages 48 and 49 for further information.

Siting flexibility
There are a substantial number of fluing options available with our boilers, giving
excellent siting flexibility for almost all applications. The Standard B pack flue is
telescopic for easy installation. The range of options include components such as
roof flue and powered vertical flue kits which ensure that the installer encounters
minimum restricti
