Heating not available - Who bears the costs?

Good morning,

as is probably the case with many, our heat pump is currently not available for delivery.
Next week the screed will be installed and then sometime later probably the HotBoy, which surely consumes more electricity than the heat pump for heating the screed.
Also for after that, the question arises how the house should continue to be heated and who will cover the additional costs compared to the heat pump.

I had contact with the company Nibe, which told me about an alternative and supposedly immediately deliverable heating system, which, however, is more expensive than the one ordered –
also here the question is whether it is reasonable to expect the construction company to bear these costs in order to keep the contractually agreed construction time, or if I can be glad to receive even a one euro subsidy?

Maybe you can help.
Have a nice holiday!

What does the contract say regarding construction power?

Also from me the question, what is stated in the contract. GU or developer? What handover deadline? What contractual penalties? etc.

Hello,

this is a general contractor,
construction power is provided by the client,
the construction period is 6 months plus bad weather time from 12/1 to 3/31,
work started on 07/05/22.

But I really can't do anything about the fact that the ordered heating system is not delivered,
the general contractor also receives "compensation for damages" from the trade for the delay penalty to us, doesn't he?

Screed is usually dried by the heat pump's heating element. Therefore, it does not (significantly) matter. Energy usage is still 1:1.

Why would you do that if the heat pump is already installed?
Ours has a special screed drying program; it ran completely normally.
