Contrary to solar panels or photovoltaics only scant attention is devoted
to the subject of modernization of heating systems. Studies have shown
that heating systems are being used much longer than the estimated life
span supposed by the manufacturers. In Germany the average age of a burner
is approximately 25 years. But oftentimes systems are in use for 30 years
and more. Experts therefore assume considerable backlog for the
modernization of heating systems.
Since November 2004 aggravate limit values for allowable stack loss of
heating systems are in effect. Since then heating systems with an output
of 25 kW, which are installed in most single or semidetached houses, have
to be renewed, if they show a stack loss of more than 11 percent.
On this occasion the Bremer Energie Konsens GmbH has been trying to motivate
homeowners to install energy efficient heating systems. For this purpose
the campaign "focus: heating" was started in mid of 2004 in cooperation
with swb Enordia, the heating-plumbing-air conditioning guild and the
guild of the chimney sweepers Bremen/Bremerhaven. The campaign has been
accompanied by intensive public relation. Its main focus has been to advise
homeowners on the subject of highly efficient burner technology, solar
systems and wood pellet heaters. The campaign includes the internet portal
www.brennpunkt-heizung.de as well as a hotline and information and
advisory offers.
Aim of the research project was the evaluation of the information and
advisory campaign "focus: heating" which was conducted by the Bremer
Energie Konsens GmbH. On the one hand motivational barriers and restraints
preventing a renewal of heating systems were explored. On the other hand it
was analyzed how far the information and advisory campaign was able
to reduce those restraints.
Using telephone interviews and group
discussions the needs on information and advice around the subject of
modernization of heating systems were being surveyed.
Furthermore the
knowledge about the information and advisory offered are being identified
and the assessment of the advisory services and their impact on a decision
against or in favour of modernization were being examined.
Based on the results of the evaluation proposals for the further
development of the campaign were being compiled. In addition hints
for further activities encouraging energy efficient modernization of homes
were being developed, to be picked up at coming activities of the Bremer
Energie Konsens GmbH.
