Warmth where it’s needed, when it’s needed in a single room
or across the home. A constant low level of background heat
prevents the fabric of the building from cooling. On demand,
this fast-acting appliance raises the temperature to meet your
needs, providing total control and low running costs.
Eco-Response
Intelligent heating technology
Advanced control heating systems – Eco-Response
Stored heat – maintains low level
background heat to keep the fabric of
the building warm, utilising economy
off-peak electricity.
Simple integral control on top of
the heater – allows easy adjustment
to achieve the user’s preferred
comfort temperature.
Radiant heat – rapidly raises
temperature to required comfort level
on demand.
PART L and SAP 2005
The Creda Eco-Response has been developed to help meet the needs of Part L 2006 Building Regulations and
provides enhanced SAP scores.
Specifiers will benefit from the ‘integrated storage/direct acting heater’ category within table 4a of SAP 2005
which rewards the enhanced controllability of Eco-Response with a 100% efficiency rating, placing this leading
technology in heating type 2 with a responsiveness weighting of 0.75.
Conventional heater
Why Eco-Response?
With a conventional ‘wet’
heating system, when heating
goes off, building shell cools.
The building shell has to then
be warmed again before room
feels comfortable.
This takes time and energy –
slow response.
Eco-Response
It is smarter to maintain low
level background heat.
The room temperature can be
raised quickly and efficiently
when needed.
Economical.
Responsive.
Intelligent.
Matching TPRIII E Electronic panel
heaters also available for pilot wire linked
heating systems (See pages 22-23).
Control options
4 zone pilot wire central controller
Allows 7 day programming of
comfort/setback time settings of
multiple pilot wire linked heaters in
up to 4 separate zones. See pages
22-23 for more details.
