What about systems that contain

different products?

In these circumstances, there is a responsibility to

provide a package label when combining a heating

appliance with a temperature control and/or solar

device, cylinder or a supplementary heating

appliance (for example, a two-boiler cascade with

a combined total output of under 70kW).

The person who puts that package together will

need to produce a package document known as

a ﬁ che (data table) and label that provides the

combined energy efﬁ ciency rating rather than

ratings of each individual component.

For example, this could be the merchant’s

responsibility if they supply a complete package

under one part number or the installer if the

items are bought individually under separate

part numbers.

In either circumstance, Worcester will provide an

online tool that makes calculating the overall

package efﬁ ciency of a Worcester system effortless.

What about controls?

The ErP Directive covers all products that

consume energy, such as boilers, heat pumps,

solar thermal etc. It also includes controls,

which are deﬁ ned using ‘classes’. These run

from Class I (a simple on/off room stat) through

to Class VIII (multi-sensor room control for use

with modulating heating appliances).

Each control class equates to a certain percentage

uplift in system efﬁ ciency e.g. a class VI weather

compensating control and room thermostat will add

4% efﬁ ciency to the heating system. Details of the

controls class for each Worcester control can be

found on each product page.
