Some will need just seconds and go forthe last winter's solution, but others will seriously consider changes or even take action to implement those. What is driving their decision? The other side is the tenant, thousands of private households or the "consumer" paying for a service unavoidable linked to the winter season in Germany. This side most likely rethinks their spending when they get the annual receipt of operating expenses. There is not really an option they have to avoid or reduce the costs related to winter services. Moreover, those costs are not even related to direct consumption. So, do tenants look for ways to reduce costs for winter services? Do they see value in this service or how much they are willing to spend for it?The objective of this assignment is to answer the raised questions.
