Ideal's Concord range continues to lead the market with value for
money gas atmospheric boilers for commercial or industrial applications.
Ideal boasts the widest range of gas atmospheric boilers, which
incorporate outputs from 40kW to 380kW in a singular boiler and
up to 720kW in Modular format. The Concord range has a host of
features making them suitable for most heating systems.
The Concord range includes:
CXA/H
Now with Auto ignition
(40-120kW)
CXAP/H
Propane option
(40-100kW)
CXS/H
High / Low operation with Standard control panel
(40-120kW)
CXSi/H
High output with Standard control panel
(110-180kW)
ES/H
High output providing adjustable High / Low operation
(140-380kW)
Concord Modular
(80-720kW)
As well as having a boiler for every application, Ideal Boilers are
also committed to improving boiler efficiency and reducing
emissions, as a result we can now demonstrate conformance to the
new Building Regulations 2006 Part L2 (Section 6).
Ideal is the only company in its field to have achieved `Word Class
Manufacturer' accreditation in the prestigious IBM and London
Business School UK manufacturing survey. Our Hull based factory is
part of only 2% of all manufacturing sites in the UK that have been
independently judged as meeting the criteria of World Class manu-
facturing status, while our superior manufacturing facilities mean
that we can achieve `right first time' quality. In accordance with the
company's World Class status, we have adopted a programme of
continuous improvement which ensures that we constantly measure
and monitor our performance to drive improvement through
innovation.
To ensure the products' reliability, each of our boilers is subjected to
an extraordinarily stringent regime of product assessment. This
includes rigorous application testing, as well as extensive laboratory
and field trials.
